Technical Field

The present invention relates to novel catechol surfactants, additives, emulsifiers, and the like, methods of making, and compositions and methods of using such compositions in a variety of applications.

Background

The dispersing additive helps to disperse small or fine particles into the liquid medium. Such dispersants are useful in coatings, plastics, cosmetics, and the like. Suitable dispersants are capable of dispersing such fine or small particles as finely and efficiently as possible into the liquid medium, which remains stable over time. However, one problem with the dispersants currently available is that the dispersion of the fine particles in the liquid is unstable, since these particles tend to agglomerate or flocculate over time in products where dispersibility is desired, causing changes in properties, such as different colour shades, uneven dyeing, changes in rheology, and other undesirable properties.

In particular, the coating may have a wide variety of other additives, which are typically added in small amounts, yet provide a significant impact on the product. Some examples include additives that alter surface tension, improve flow characteristics, improve final appearance, increase wet edge, improve pigment stability, impart freeze protection properties, control foaming, control skinning, and the like. Other types of additives include catalysts, thickeners, stabilizers, emulsifiers, conditioners, adhesion promoters, UV stabilizers, flatting agents (matting agents), biocides used to combat bacterial growth, and the like. Additives generally do not significantly alter the percentage of individual components in the formulation.

Surfactants are used as wetting agents, anti-foaming agents and dispersants in the paint and coating additives market.

Disclosure of Invention

Additives or thickeners may be used in a variety of liquid systems, including aqueous systems, such as paints, aqueous inks, and personal care products, and compositions for treating subterranean formations. These additives improve rheology by also affecting the dispersion, suspension, and emulsification of pigments, binders, and other solids within the vehicle.

The present invention relates to the use of a specific family of alkoxylated compounds with large hydrophobic groups, such as alkoxylated substituted catechols, for improving properties, in particular dispersibility, freeze-thaw stability, open time, low temperature film formation, stain resistance, film gloss, hiding and scrub resistance, blister resistance, blocking resistance, adhesion and water sensitivity, in compositions, such as in paints and coatings.

In another embodiment, the emulsifier added is between about 1.6% and 7.5% by weight of a polymer or monomers used to form the latex polymer. In another embodiment, the emulsifier added is between about 1.6% and 45% by weight of the polymer or monomer used to form the latex polymer, typically between about 1.6% and 35% by weight of the polymer or monomer used to form the latex polymer

In another embodiment, these compounds as described herein may be used as additives to an aqueous dispersion of an already formed latex polymer.

In some embodiments, the additive is a freeze-thaw additive that may be added at any point in the production of the aqueous coating composition, including but not limited to during the emulsification step, during formulation, and the like. It is also understood that the freeze-thaw additive may be added to the aqueous coating composition or concentrate thereof after addition.

This results in an aqueous composition comprising the surface active alkoxylated compound and the latex polymer. When the surface active alkoxylated compound is used as an additive to an already formed aqueous latex dispersion, the resulting composition has the alkoxylated compound additive in an amount of about 1 to 10, typically 2 to 8 or 2 to 6 parts per 100 parts by weight of the monomers used to form the latex polymer.

In another embodiment, the above surface-active compounds having any of the above structural formulae may be used as additives during formulation of a paint or water-borne coating composition. Formulation is the stage of adding the additive to the base aqueous latex polymer dispersion to render it a final product such as a paint or coating. When the surface active alkoxylated compound is used as an additive to an already formed paint or aqueous coating composition, such as an aqueous latex coating dispersion, the resulting composition has the alkoxylated compound additive typically in an amount of greater than about 1.3% by weight of the polymer or monomer used to form the latex polymer, more typically in an amount of greater than about 1.6% by weight of the polymer or monomer used to form the latex polymer, still more typically in an amount of greater than about 2% by weight of the polymer or monomer used to form the latex polymer, even more typically in an amount of greater than about 4% by weight of the polymer or monomer used to form the latex polymer, and most typically in an amount of greater than about 7.5% by weight of the polymer or monomer used to form the latex polymer. In another embodiment, the latex coating composition contains a surface active alkoxylated compound in an amount between about 1.6% and 7.5% by weight of the polymer or monomer used to form the latex polymer. In another embodiment, the latex coating composition contains a surface active alkoxylated compound in an amount of between about 1.6% and 45%, typically between 1.6% and 35%, by weight of the polymer or monomers used to form the latex polymer. Pigments are typical additives added, for example, during the formulation of paint coatings from raw aqueous latex polymer dispersions.

The aqueous coating composition of the present invention is freeze-thaw stable, wherein the freeze-thaw additive is present in the aqueous coating composition in an amount of polymer as described above by weight, wherein the polymer may have a Tg between about-15 ℃ and about 12 ℃ and an average particle size of less than about 200nm, or a Tg between about-5 ℃ and about 5 ℃ and an average particle size of less than about 200nm, or a Tg between about-5 ℃ and about 0 ℃ and an average particle size of less than about 200nm, or a Tg between about-15 ℃ and about 12 ℃ and an average particle size of less than about 190nm, or a Tg between about-5 ℃ and about 5 ℃ and an average particle size of less than about 190nm, or a Tg between about-5 ℃ and about 0 ℃ and an average particle size of less than about 190nm, or a Tg between about-15 ℃ and about 12 ℃ and an average particle size of less than about 175nm, Or a Tg between about-5 ℃ and about 5 ℃ and an average particle size of less than about 175nm, or a Tg between about-5 ℃ and about 0 ℃ and an average particle size of less than about 175 nm. As noted above, the average particle size is typically between about 75nm and about 400 nm. The aqueous coating composition may be characterized by an open time of greater than about 2 minutes, an open time of greater than about 4 minutes, an open time of greater than about 6 minutes, or an open time of greater than about 12 minutes.

The present invention further comprises a process for preparing a paint or water-borne coating composition, which process comprises adding at least one surface-active alkoxylated compound of any of the formulae above during the formulation of the paint or water-borne coating composition comprising at least one pigment and further additives to produce the final paint or water-borne coating composition. The addition of the surface active alkoxylated compound surfactant (emulsifier) during the formulation of the paint or aqueous coating composition forms a coating composition with a lower VOC content while maintaining the freeze-thaw stability of the aqueous coating composition at a desired level.

As mentioned above, in some embodiments, the aqueous coating composition may comprise less than 2.0% of an anti-freeze agent, based on the total weight of the aqueous coating composition. Exemplary anti-freezing agents include ethylene glycol, diethylene glycol, propylene glycol, glycerol (1,2, 3-trihydroxypropane), ethanol, methanol, 1-methoxy-2-propanol, 2-amino-2-methyl-1-propanol, and FTS-365 (a freeze-thaw stabilizer from Inovache Specialty Chemicals). More typically, the aqueous coating composition comprises less than 1.0% of an anti-freeze or is substantially free of (e.g., comprises less than 0.1%) of an anti-freeze. Thus, the waterborne coating compositions of the present invention typically have VOC levels of less than about 100g/L, and more typically less than or equal to about 50 g/L. Although the waterborne coating compositions of the present invention contain little or no anti-freeze agent, these compositions have a level of freeze-thaw stability that is desirable in the art.

For example, waterborne coating compositions of the present invention can withstand freeze-thaw cycles without setting using ASTM method D2243-82 or ASTM D2243-95.

The balance of the aqueous coating composition of the present invention is water. Although much water is present in the polymer latex dispersion and in the other components of the aqueous coating composition, water is typically still added separately to the aqueous coating composition. Typically, the aqueous coating composition comprises from about 10% to about 85% by weight, and more typically from about 35% to about 80% by weight, of water. In other words, the total solids content of the aqueous coating composition is typically from about 15% to about 90%, more typically from about 20% to about 65%.

Latex paints and coatings may contain various adjuvants, such as pigments, fillers, and extenders. Useful pigments include, but are not limited to, titanium dioxide, mica, and iron oxide. Useful fillers and extenders include, but are not limited to, barium sulfate, calcium carbonate, clay, talc, and silica. The compositions of the invention described herein are compatible with most latex paint systems and provide very effective and efficient thickening.

Physical properties that may be considered in formulating latexes and latex paints/coatings include, but are not limited to, viscosity versus shear rate, ease of application to a surface, expandability, and shear thinning.

Emulsion Polymerization is discussed in g.pohlein, "Emulsion Polymerization [ Emulsion Polymerization ]", Encyclopedia of Polymer Science and Engineering [ Polymer Science and Engineering Encyclopedia ], volume 6, pages 1-51 (John Wiley & Sons [ John Wiley father publishers, new york, 1986), the disclosure of which is incorporated by reference herein. Emulsion polymerization is a heterogeneous reaction process in which unsaturated monomers or monomer solutions are dispersed in a continuous phase with the aid of an emulsifier system and polymerized with free radicals or redox initiators. The product, i.e., a colloidal dispersion of a polymer or polymer solution, is referred to as a latex.

Monomers typically used in emulsion polymerization to prepare latexes for latex painting include monomers such as: methyl acrylate, ethyl acrylate, methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, other acrylic esters, methacrylic esters and blends thereof, acrylic acid, methacrylic acid, styrene, vinyl toluene, vinyl acetate, vinyl esters of higher carboxylic acids than acetic acid (e.g., vinyl versatate), acrylonitrile, acrylamide, butadiene, ethylene, vinyl chloride, and the like, and mixtures thereof. This is further discussed in the section entitled "latex monomers" below.

In the above process, suitable initiators, reducing agents, catalysts and surfactants are well known in the art of emulsion polymerization. Typical initiators include Ammonium Persulfate (APS), hydrogen peroxide, sodium, potassium or ammonium peroxodisulfate, dibenzoyl peroxide, lauroyl peroxide, di-t-butyl peroxide, 2' -azobisisobutyronitrile, t-butyl hydroperoxide, benzoyl peroxide, and the like. A commonly used redox initiation system is described, for example, by A.S. Sarac in Progress in Polymer Science [ Advance in Polymer Science ]24(1999), 1149-.

Suitable reducing agents are those that increase the rate of polymerization and include, for example, sodium bisulfite, sodium dithionate, sodium formaldehyde sulfoxylate, ascorbic acid, erythorbic acid, and mixtures thereof.

Suitable catalysts are those compounds which increase the polymerization rate and which, in combination with the abovementioned reducing agents, promote the decomposition of the polymerization initiator under the reaction conditions. Suitable catalysts include transition metal compounds such as, for example, ferrous sulfate heptahydrate, ferrous chloride, copper sulfate, copper chloride, cobalt acetate, cobalt sulfate, and mixtures thereof.

The emulsion polymerization takes place in the presence of an emulsifier. Typically, the mixture contains 0.01 to 6 wt% (or 0.05 to 6 wt% in other embodiments) emulsifier based on the weight of the latex monomers.

Typical emulsifiers, in addition to the compounds as described herein, are ionic or nonionic surfactants that may or may not be polymerizable in aqueous coating compositions comprising latex polymers. Suitable ionic and nonionic surfactants are alkyl polyglycol ethers, such as ethoxylation products of lauryl, tridecyl, oleyl and stearyl alcohols; alkylphenol polyglycol ethers, such as ethoxylation products of octylphenol or nonylphenol, diisopropylphenol, triisopropylphenol; alkali metal or ammonium salts of alkyl, aryl or alkylaryl sulfonates, sulfates, phosphates and the like, including sodium lauryl sulfate, sodium octylphenol glycolether sulfate, sodium dodecylbenzene sulfonate, sodium lauryl diglycol sulfate, and ammonium tri-tert-butylphenolate and ammonium penta-and octa-ethyleneglycolsulfonates; sulfosuccinates such as ethoxylated nonylphenol half ester disodium salt of sulfosuccinic acid, disodium n-octyldecyl sulfosuccinate, sodium dioctyl sulfosuccinate, and the like.

The polymer latex binder may be produced by first preparing an initiator solution comprising an initiator and water. A monomer pre-emulsion is also prepared that contains one or more surfactants (emulsifiers), and other latex monomers to be used in forming the latex polymer, water, and additional additives such as NaOH.

Thus, a typical process for emulsion polymerization preferably involves filling the reactor with water and feeding the monomer pre-emulsion and initiator solution as separate streams. Specifically, the polymer latex binder can be prepared by: using emulsion polymerization, monomers for forming the latex binder are fed into a reactor in the presence of at least one initiator and at least one surfactant and the monomers are polymerized to produce the latex binder. Typically, the initiator solution and monomer pre-emulsion are continuously added to the reactor over a predetermined period of time (e.g., 1.5-5 hours) to polymerize the latex monomers, thereby producing the latex polymer.

A seed latex, such as a polystyrene seed latex, may be added to the reactor prior to the addition of the initiator solution and monomer pre-emulsion. For example, a small amount of pre-emulsion and a portion of the initiator may be initially charged at the reaction temperature to produce the "seed" latex. This "seed" latex procedure results in better particle size reproducibility.

Polymerization is carried out under "standard" initiation conditions (i.e., initiation conditions under which the initiator is activated by heat), typically at about 60 ℃ to 90 ℃. A typical "standard" initiation procedure may employ, for example, ammonium persulfate as the initiator at reaction conditions of 80+/-2 ℃. The polymerization is carried out under "redox" initiation conditions (i.e., initiation conditions under which the initiator is activated by a reducing agent), typically at 60 ℃ to 70 ℃. Typically, the reducing agent is added as a separate solution. A typical "redox" initiation procedure may, for example, employ potassium persulfate as the initiator and sodium metabisulfite as the reducing agent at reaction conditions of 65+/-2 ℃.

The reactor is operated at the desired reaction temperature at least until all of the monomers are fed to produce the polymer latex binder. Once the polymer latex adhesive is prepared, it is preferably chemically stripped to reduce its residual monomer content. Preferably, it is chemically stripped by continuously adding an oxidizing agent such as a peroxide (e.g., t-butyl hydroperoxide) and a reducing agent (e.g., acetone sodium bisulfite) or another redox pair (such as those described by a.s. sarac in polymer science evolution 24(1999), 1149-. The pH of the latex binder may then be adjusted and other additives added after the chemical stripping step.

In the above emulsions, the polymer is preferably present as generally spherical particles dispersed in water having a diameter of about 50 nanometers to about 500 nanometers.

For the purposes of this specification, monomers from which latex polymers can be derived are referred to as "latex monomers".

The latex monomers fed to the reactor to prepare the polymer latex binder preferably include at least one acrylic monomer selected from the group consisting of: acrylic acid, acrylic acid esters, methacrylic acid, and methacrylic acid esters. In addition, these monomers may include styrene, vinyl acetate, or ethylene. These monomers may also include one or more monomers selected from the group consisting of: styrene, (alpha) -methylstyrene, vinyl chloride, acrylonitrile, methacrylonitrile, ureido methacrylate, vinyl acetate, vinyl esters of branched tertiary monocarboxylic acids (e.g., the vinyl esters commercially available under the trademark VEOVA from Shell Chemical Company or sold as EXXAR new vinyl esters by ExxonMobil Chemical Company), itaconic acid, crotonic acid, maleic acid, fumaric acid, and ethylene. It is also possible to include C4-C8 conjugated dienes, such as 1, 3-butadiene, isoprene or chloroprene. Monomers commonly used in making acrylic paints are butyl acrylate, methyl methacrylate, ethyl acrylate, and the like. Preferably, the monomers include one or more monomers selected from the group consisting of: n-butyl acrylate, methyl methacrylate, styrene, and 2-ethylhexyl acrylate.

The latex polymer is typically selected from the group consisting of: pure acrylic (including acrylic acid, methacrylic acid, acrylate esters, and/or methacrylate esters as the main monomers); styrene acrylics (including styrene and acrylic acid, methacrylic acid, acrylates, and/or methacrylates, as the primary monomers); vinyl acrylics (including vinyl acetate and acrylic, methacrylic, acrylate, and/or methacrylate esters as primary monomers); and acrylated ethylene vinyl acetate copolymers (including ethylene, vinyl acetate and acrylic acid, methacrylic acid, acrylates, and/or methacrylates as primary monomers). These monomers may also include other primary monomers such as acrylamide and acrylonitrile, and one or more functional monomers such as itaconic acid and ureido methacrylate, as will be readily understood by those skilled in the art. In a particularly preferred embodiment, the latex polymer is pure acrylic, such as a butyl acrylate/methyl methacrylate copolymer derived from monomers including butyl acrylate and methyl methacrylate.

In a typical acrylic paint composition, the polymer is composed of one or more esters of acrylic or methacrylic acid, typically a mixture of, for example, about 50/50 by weight of a high Tg monomer (e.g., methyl methacrylate) and a low Tg monomer (e.g., butyl acrylate) along with a minor proportion (e.g., about 0.5% to about 2% by weight) of acrylic or methacrylic acid. Vinyl-acrylic paints generally comprise vinyl acetate and butyl acrylate and/or 2-ethylhexyl acrylate and/or vinyl versatate. In vinyl-acrylic paint compositions, at least 50% of the polymer formed is composed of vinyl acetate, the remainder being esters selected from acrylic or methacrylic acid. Styrene/acrylic polymers are typically similar to acrylic polymers in that styrene replaces all or part of its methacrylate monomers.

The latex polymer dispersion preferably comprises from about 30% to about 75% solids and an average latex particle size of from about 70nm to about 650 nm. The latex polymer is preferably present in the aqueous coating composition in an amount of from about 5% to about 60% by weight, and more preferably from about 8% to about 40% by weight (i.e., weight percent of dry latex polymer based on the total weight of the coating composition).

The aqueous coating composition is a stable fluid that can be applied to a wide variety of materials, such as, for example, paper, wood, concrete, metal, glass, ceramic, plastic, gypsum, and roofing substrates such as asphalt coatings, roofing felts, foamed polyurethane insulation; or to a previously painted, primed, abraded or weathered substrate. The aqueous coating compositions of the present invention can be applied to these materials by a variety of techniques well known in the art, such as, for example, brushes, rollers, mops, air-assisted or airless spray, electrostatic spray, and the like.

In one embodiment, the liquid carrier is an aqueous carrier comprising water, and the treatment solution is in the form of a solution, emulsion, or dispersion of the materials and additives. In one embodiment, the liquid carrier comprises water and a water-miscible organic liquid. Suitable water-miscible organic liquids include saturated or unsaturated mono-and polyhydric alcohols, such as, for example, methanol, ethanol, isopropanol, cetyl alcohol, benzyl alcohol, oleyl alcohol, 2-butoxyethanol and ethylene glycol; and alkyl ether glycols such as, for example, ethylene glycol monoethyl ether, propylene glycol monoethyl ether and diethylene glycol monomethyl ether.

As used herein, the terms "aqueous medium" and "aqueous medium" are used herein to refer to any liquid medium in which water is the major component. Thus, the term includes water per se as well as aqueous solutions and dispersions.

VI.Other additives

As noted above, latex paints and coatings may contain various adjuvants.

The aqueous coating composition of the present invention comprises less than 2% by weight and preferably less than 1.0% by weight of an anti-freeze, based on the total weight of the aqueous coating composition. For example, the aqueous coating composition may be substantially free of an anti-freeze agent.

The aqueous coating composition typically comprises at least one pigment. The term "pigment" as used herein includes non-film-forming solids such as pigments, extenders, and fillers. The at least one pigment is preferably selected from the group consisting of: TiO2 (in both anatase and rutile form), clay (aluminum silicate), CaCO3 (in both ground and precipitated form), alumina, silica, magnesia, talc (magnesium silicate), barite (barium sulfate), zinc oxide, zinc sulfite, sodium oxide, potassium oxide, and mixtures thereof. Suitable mixtures include blends of metal oxides such as those sold under the following trademarks: MINEX (oxides of silicon, aluminum, sodium and potassium, commercially available from UNIMIN Specialty Minerals), CELITES (alumina and silica, commercially available from SHICINE CORPORATION), ATOMITITES (commercially available from English China Clay International), and ATTAGELS (commercially available from Engelhard, Inc.). More preferably, the at least one pigment comprises TiO2, CaCO3, or clay. Typically, the average particle size of the pigment ranges from about 0.01 to about 50 microns. For example, the TiO2 particles used in the aqueous coating composition typically have an average particle size of from about 0.15 to about 0.40 microns. The pigment may be added to the aqueous coating composition as a powder or in the form of a slurry. The pigment is preferably present in the aqueous coating composition in an amount of from about 5% to about 50% by weight, more preferably from about 10% to about 40% by weight.

The coating composition may optionally contain additives such as one or more film forming or coalescing agents. Suitable coalescing or film forming agents include plasticizers and drying inhibitors such as high boiling polar solvents. Other conventional coating additives such as, for example, dispersants, additional surfactants (i.e., wetting agents), rheology modifiers, defoamers, thickeners, additional biocides, additional mildewcides, colorants (e.g., colored pigments and dyes), waxes, fragrances, co-solvents, and the like, can also be used in accordance with the present invention. For example, nonionic and/or ionic (e.g., anionic or cationic) surfactants can be used to produce the polymer latex. These additives are typically present in the aqueous coating composition in an amount of from 0% to about 15% by weight, more preferably from about 1% to about 10% by weight, based on the total weight of the coating composition.

The aqueous coating composition typically comprises less than 10.0% of an anti-freeze agent, based on the total weight of the aqueous coating composition. Exemplary anti-freezing agents include ethylene glycol, diethylene glycol, propylene glycol, glycerol (1,2, 3-trihydroxypropane), ethanol, methanol, 1-methoxy-2-propanol, 2-amino-2-methyl-1-propanol, and FTS-365 (a freeze-thaw stabilizer from Inovache Specialty Chemicals). More preferably, the aqueous coating composition comprises less than 5.0% or is substantially free (e.g., comprises less than 0.1%) of antifreeze. Thus, the waterborne coating compositions of the present invention preferably have VOC levels of less than about 100g/L, and more preferably less than or equal to about 50 g/L.

The balance of the aqueous coating composition of the present invention is water. Although much water is present in the polymer latex dispersion and in the other components of the aqueous coating composition, water is typically still added separately to the aqueous coating composition. Typically, the aqueous coating composition comprises from about 10% to about 85% by weight, and more preferably from about 35% to about 80% by weight, of water. In other words, the total solids content of the aqueous coating composition is typically from about 15% to about 90%, and more preferably from about 20% to about 65%.

These coating compositions are typically formulated such that the dried coating comprises at least 10% by volume of dry polymeric solids, and additionally from 5% to 90% by volume of non-polymeric solids in the form of pigments. The dry coating may also include additives that do not evaporate upon drying the coating composition, such as plasticizers, dispersants, surfactants, rheology modifiers, defoamers, thickeners, additional biocides, additional mildewcides, colorants, waxes, and the like.
