The technical scheme protects a novel water-based emulsified glue which is used for gluing different materials such as plates, decorative materials, paper materials, glass, films and the like, is particularly suitable for gluing organic materials and inorganic materials, has excellent gluing sealing property and gluing firmness, and does not contain pollutants such as benzaldehyde and the like; the novel water-based emulsified glue comprises the following components in percentage by mass:

5-10% of chloroprene resin;

35-40% of butyronitrile resin;

water-based auxiliary agent: 1 to 2 percent;

functional auxiliary agents: 0.5-1%;

the balance of water.

The chloroprene resin is also called chloroprene rubber or chloroprene rubber, can also be called chloroprene rubber, and is an elastomer prepared by alpha-polymerization of chloroprene (namely 2-chloro-1, 3-butadiene) serving as a main raw material. The chloroprene resin has good physical and mechanical properties, and is excellent in oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, aging resistance and chemical corrosion resistance; the adhesive has high tensile strength, elongation and reversible crystallinity, and good adhesion; the weather resistance and the ozone aging resistance are second to those of ethylene propylene rubber and butyl rubber; the heat resistance is equivalent to that of nitrile rubber, the decomposition temperature is 230-260 ℃, the rubber can resist 120-150 ℃ in a short period, the rubber can be used for a long time at 80-100 ℃, and the rubber has certain flame retardance; the oil resistance is second only to nitrile rubber; good inorganic acid and alkali corrosion resistance.

Moreover, the chloroprene rubber is similar to a natural rubber in structure, and is different from the chloroprene rubber in that polar electronegative groups in the chloroprene rubber replace methyl groups in the natural rubber, so that the ozone resistance, oil resistance and heat resistance of the chloroprene rubber are improved, and the comprehensive physical and mechanical properties of the chloroprene rubber are better, so that the chloroprene rubber has very wide application, can be used as general rubber and special rubber, and has the following main physical and mechanical properties:

(1) strength of chloroprene rubber: the tensile property of the chloroprene rubber is similar to that of natural rubber, and the raw rubber has high tensile strength and elongation at break and belongs to self-reinforcing rubber; the molecular structure of the chloroprene rubber is regular, and the molecular chain contains chlorine atom polar groups, so that the intermolecular acting force is increased. Therefore, under the action of external force, the crystal is easy to stretch and crystallize (self-reinforcing property) and the molecules are not easy to slip. In addition, the molecular weight is large (2.0 to 20 ten thousand), so that the tensile strength is large.

(2) Excellent aging resistance: chlorine atoms connected with double bonds of a chloroprene rubber molecular chain enable the double bonds and the chlorine atoms to be inactive, so that the storage stability of vulcanized rubber is good; is not easy to be influenced by heat, oxygen and light in the atmosphere, and has excellent aging resistance (weather resistance, ozone resistance and heat resistance). The ageing resistance of the rubber is particularly weather resistance and ozone resistance, and is inferior to ethylene propylene rubber and butyl rubber in general rubber and far superior to natural rubber.

(3) Excellent flame resistance: the chloroprene rubber has the best flame resistance in general rubber, has the characteristic of non-spontaneous combustion, can be combusted when contacting with flame, but can be automatically extinguished when blocking the flame, because the chloroprene rubber can decompose hydrogen chloride gas under the action of high temperature when being combusted, so that the fire is extinguished.

(4) Chloroprene rubber is also excellent in chemical resistance, and other acids and alkalis have little effect on it except for strong oxidizing acids. Neoprene also has better water resistance than other synthetic rubbers.

The nitrile-butadiene resin is nitrile-butadiene rubber (NBR), is a copolymer formed by polymerizing acrylonitrile and butadiene monomers, is mainly produced by a low-temperature emulsion polymerization method, has excellent oil resistance, higher wear resistance, better heat resistance and strong bonding force, and has the following main physical and mechanical properties:

(1) NBR has excellent oil resistance, and the NBR typically has a structure in which trans forms about 78%. Because the NBR contains cyano in the molecular chain structure, the oil resistance (such as mineral oil resistance, liquid fuel resistance, animal and vegetable oil resistance and solvent resistance) is superior to that of natural rubber, chloroprene rubber and styrene-butadiene rubber.

(2) The NBR has good chemical stability and good processing performance, and the relative density of the NBR is increased along with the content of acrylonitrile in the structure, so that the vulcanization speed is accelerated, and the tensile strength performance is improved.

(3) The NBR has better heat resistance, the heat resistance of the NBR is better than that of natural rubber and styrene butadiene rubber, the long-term use temperature can reach 100 ℃, and the NBR can be used for 40 days at 120 ℃. Meanwhile, the NBR has good low temperature resistance, and the minimum glass transition temperature can reach-55 ℃.

Although the chloroprene resin has the advantages, the chloroprene resin also has the defects of poor heat resistance, poor cold resistance, incapability of being used for bonding in contact with water or under a humid condition and the like, and the butyronitrile resin has better heat resistance and cold resistance (the butyronitrile resin can resist the low temperature of minus 40 ℃), and can obtain better balance of performances such as aging resistance, oil resistance, cold resistance and the like when used together with the chloroprene resin; although the combination of the chloroprene resin and the nitrile resin can achieve a balance of various properties, in actual production and use, the chloroprene resin and the nitrile resin are rarely used together because the chloroprene resin and the nitrile resin cannot be well emulsified at all by using a common emulsification method (because the surface tension of the chloroprene resin and the nitrile resin is large and the common emulsification method cannot emulsify the chloroprene resin and the nitrile resin), and the chloroprene resin and the nitrile resin cannot be uniformly dispersed with each other to form a latex state, so that the use requirement cannot be met. In the technical scheme, in order to solve the emulsification problem of the chloroprene resin and the nitrile resin, the chloroprene resin and the nitrile resin are prepared into emulsion glue by adopting an ultrasonic high-efficiency vacuole emulsification function, so that the chloroprene resin and the nitrile resin can be used together.

In certain embodiments, the aqueous adjuvant includes, but is not limited to, one or more combinations of dispersants, suspending agents, defoamers, and release agents.

Aqueous suspensions are those using water as the solvent, such as aqueous nanocellulose suspensions). The oil suspending agent is oil as main solvent and contains no water, wherein the common oil is vegetable oil such as corn oil, rapeseed oil, etc., or artificially synthesized oil.

The defoaming agent can be used for breaking, inhibiting and defoaming foams in materials in the process of material mixing reaction, so that the foam is prevented from influencing the mixing reaction of the materials, and the obtained water-based emulsified glue is ensured to meet the performance requirement.

In certain embodiments, the defoaming agent includes, but is not limited to, non-silicon type, polyether type (including GP type, GPE type, GPEs type), silicone type, and polyether modified silicone type, and the like, for example, polysiloxane defoaming agent, polyether modified silicone oil, trialkyl melamine, cyanuric chloride melamine, fatty amine, and the like.

The release agent can enable the prepared water-based emulsified glue to be smoothly released from a device, and meanwhile, the surface of the prepared water-based emulsified glue is smooth and clean, so that the production efficiency is improved, and the production quality is ensured.

In some embodiments, the release agent includes, but is not limited to, inorganic, organic and polymer, inorganic release agents, such as talc, mica powder, and compounds prepared from clay, white clay, etc. as main components; the organic release agent includes fatty acid soap (potassium soap, sodium soap, ammonium soap, zinc soap, etc.), fatty acid, paraffin, glycerin, vaseline, etc.; the high polymer release agent comprises silicone oil, polyethylene glycol, low molecular weight polyethylene and the like, and the release agent efficiency and the thermal stability of the high polymer release agent are much better than those of organic release agents.

In certain embodiments, the functional adjuvant includes, but is not limited to, one or more combinations of stain repellents, antimicrobial agents, flame retardants, plasticizers.

The anti-fouling agent can form a hydrophilic and durable film on the surface of the prepared novel flexible decorative material, and the film can play an anti-fouling role, so that the prepared novel flexible decorative material has an anti-fouling function.

In certain embodiments, the soil resist agents include, but are not limited to, polyacrylates, fluoro-products thereof, and the like.

The antibacterial agent can enable the surface of the prepared novel flexible decorative material to have the functions of inhibiting bacteria and preventing bacteria from breeding, so that the prepared novel flexible decorative material meets the use requirement.

In certain embodiments, the antimicrobial agents include, but are not limited to, inorganic antimicrobial agents, organic antimicrobial agents, and natural antimicrobial agents, such as nano-silver antimicrobial agents, nano-copper antimicrobial agents, nano-zinc antimicrobial agents, antimicrobial powders, antimicrobial masterbatches, and the like.

The plasticizer is a high polymer material auxiliary agent, and the flexibility of the water-based emulsified glue is enhanced by adding the substance in the water-based emulsified glue processing, so that the water-based emulsified glue with the performance meeting the requirement is obtained and is easy to process.

In certain embodiments, the plasticizer includes, but is not limited to, aliphatic dibasic acid ester polyol esters, chlorinated hydrocarbons, epoxies, citrates, polyesters, and the like.

Referring to fig. 1, according to the preparation method of the novel aqueous emulsified glue, neoprene resin, nitrile-butadiene resin, an aqueous auxiliary agent and a functional auxiliary agent are subjected to ultrasonic cavitation emulsification treatment to obtain the aqueous emulsified glue.

In some specific embodiments, in the preparation method, the chloroprene resin, the nitrile-butadiene resin, the aqueous auxiliary agent and the functional auxiliary agent are subjected to an ultrasonic high-efficiency cavitation emulsification function to prepare the aqueous emulsion glue, the average droplet size of the formed emulsion is small and can be 0.2-2 um, the concentration of ultrasonic emulsion is high, and the formed emulsion is more stable.

When ultrasonic wave acts on liquid, a large number of small bubbles can be generated, one reason is that tensile stress locally appears in the liquid to form negative pressure, and the reduction of the pressure leads the gas originally dissolved in the liquid to be supersaturated and to escape from the liquid to be small bubbles; another reason is that strong tensile stresses "tear" the liquid into a void, known as cavitation. The mechanical action of ultrasound can cause emulsification of liquids, liquefaction of gels, and dispersion of solids. Through ultrasonic cavitation emulsification treatment, chloroprene resin and nitrile resin which cannot be used together can be emulsified to prepare aqueous emulsified glue, so that the combined use of the chloroprene resin and the nitrile resin becomes possible.

The novel aqueous emulsified glue and the preparation method thereof are illustrated by the following examples:
