Technical Field

The invention provides a preparation method of a hard colored stone coating in the field of wall coatings.

Background

The existing paint mixed with colored stone usually takes natural stone as filler, and the prepared wall paint can generate stone effect after being brushed.

Because the color of natural stone is limited by stone species and stone components, the prepared stone paint is often not bright in color and can not be changed along with the design, so that artificial hard stone is required to be used as a filler to prepare the hard colored stone paint with rich colors so as to meet the market demand.

Disclosure of Invention

The invention provides a preparation method of a hard colored stone coating, which aims to prepare the coating by using artificial hard colored stones. The method uses ceramic glaze to prepare hard colored stone, and the hard colored stone is added into the coating to solve the technical problem of preparation of the hard colored stone coating.

The technical scheme adopted by the invention for solving the technical problems is as follows:

preparing a ceramic glaze material:

according to different fixed proportions, ceramic glazes with different colors are combined to form the same color series with different formulas. Melting the ceramic glaze in a crucible at a constant temperature, measuring the temperature by a high-temperature physical property tester and a light-measuring pyrometer at the measuring range of 800-3200 ℃, and uniformly stirring by ultrasonic waves. Then the crucible is gradually inclined, the molten liquid is blown into liquid drops under a hot air blow pipe, and the liquid drops fall into the cold water circulating at the lower part for sudden cooling to form small particles. And collecting the ceramic glaze particles, drying in a drying kiln, crushing by using a grinder, and sieving by using a 40-800-mesh sieve to obtain the ceramic glaze.

Preparing hard color stone particles:

mixing dry and clean natural sand with a certain grain size and Na₂CO₃Borax fluxing agent, COO and Ni₂O₃The adhesion agent is mixed and stirred, then the mixture is placed into a rotary kiln, natural gas is ignited, and the mixture is fired at 800-1000 ℃ for thirty minutes to melt glaze for coloring. The color is different, and the firing temperature of each specific color stone particle needs to be accurately controlled and recorded.

The positive effects are as follows: the hard color stone coating prepared by the method uses ceramic hard color stones to replace natural stones, so that the hard color stone coating has the decorative effects of variable and adjustable colors and bright and soft colors. Is suitable for being used as a hard colored stone coating and a preparation method thereof.

Detailed Description

Preparing a ceramic glaze material:

according to different fixed proportions, ceramic glazes with different colors are combined to form the same color series with different formulas. Melting the ceramic glaze in a crucible at a constant temperature, measuring the temperature by a high-temperature physical property tester and a light-measuring pyrometer at the measuring range of 800-3200 ℃, and uniformly stirring by ultrasonic waves. Then the crucible is gradually inclined, the molten liquid is blown into liquid drops under a hot air blow pipe, and the liquid drops fall into the cold water circulating at the lower part for sudden cooling to form small particles. And collecting the ceramic glaze particles, drying in a drying kiln, crushing by using a grinder, and sieving by using a 40-800-mesh sieve to obtain the ceramic glaze.

Preparing hard color stone particles:

mixing dry and clean natural sand with a certain grain size and Na₂CO₃Borax fluxing agent, COO and Ni₂O₃Mixing the adhesive, stirring, and standingAnd putting the glaze into a rotary kiln, starting to ignite natural gas, and firing for thirty minutes at 800-1000 ℃ to melt the glaze and color. The color is different, and the firing temperature of each specific color stone particle needs to be accurately controlled and recorded.

And (3) slowly cooling the particles which are melted at high temperature into glaze coloring under a rotating dispersion state to a non-adhesive dispersion and solidification state, and slowly cooling to room temperature in warm air at 120 ℃ to package the particles into a finished product. This process prevents cracking of the homogeneous glaze layer.

The hard colored stone is a melting temperature-reducing particle attached with ceramic glaze, and is also called colored pottery sand.

The glaze particles can be used as glaze for coloring ceramic sand and can also be used as filler in various colored paints.

The components in the following table are combined in different and fixed proportions to form the same color series with different formulas.

The glaze comprises the following components:

the hard color stone coating comprises the following raw materials:

clean soft water, HPMC, ASE-60, preservative, AMP-95, colored glaze ceramic particles, emulsion, mildew preventive, polyurethane rheological agent, defoaming agent and composite film forming auxiliary agent.

The HPMC is hydroxypropyl methyl cellulose.

The ASE-60 is an aqueous paint thickener.

The AMP-95 is a multifunctional amine auxiliary agent.

Preparing the hard colored stone coating:

adding the raw materials into a stirring cylinder, stirring and mixing to obtain the hard colored stone coating.

The preferable mixture ratio is as follows: in 100 parts, clean soft water is 5.80-7.10 parts, HPMC is 0.05-0.10 part of 10-20 million CP grade, ASE-600.05 parts, preservative is 0.10-0.30 part, AMP-95 is 0.05-0.20 part, 20-120 mesh painted pottery particles are 70.00-75.50 parts, emulsion with Tg of more than or equal to 30 ℃ and 50 percent is selected, mildew preventive is 0.10-0.80 part, polyurethane rheological agent is 0.10-0.15 part, defoaming agent is 0.05-0.10 part, and composite film forming additive is 1.90-2.50 parts by mass.

Selecting the hard color stone coating auxiliary agent:

film-forming auxiliary agent:

different types of synthetic resins differ in the film-forming aid used because different resins have specific solubility parameter ranges. The solubility parameter of the solvent that is a film-forming aid for a resin must be within the solubility parameter range of the resin in order to be a film-forming aid for the resin. There is no general film-forming aid.

The film forming assistant used in the hard color stone coating is a compound type, and the effect is better.

Selection of rheological aid:

the rheological additives include plasticizers, plasticizing thickeners, leveling agents, and the like.

Since the hard color stone coating is a binder, ASE, cellulose ethers, and polyurethanes are used.
