This is a new decorative material, texture paint, which is popular in the market.
The batch scraping type sand wall texture coating has high construction requirements, but the existing batch scraping type sand wall texture coating usually adopts angular gravels, so that the construction difficulty is increased.
Disclosure of Invention
The purpose of the invention is: overcomes the defects in the prior art and provides the batch scraping sand wall texture coating with low construction requirements and the preparation method thereof.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a batch scraping type sand wall texture coating comprises the following components in parts by mass: 200 parts of water 180-type organic silicon-containing powder, 2-2.4 parts of modified cellulose, 2-3 parts of dispersing agent, 1.5-2.1 parts of defoaming agent, 25-30 parts of titanium dioxide, 12-15 parts of propylene glycol methyl ether acetate film-forming assistant, 16-20 parts of glycerol, 30-50 parts of river midstream gravel, 180 parts of pure acrylic emulsion 150-type organic silicon-containing powder, 2-6 parts of gas-phase silicon dioxide, 2.1-3.6 parts of dibutyl phthalate, 1.2-3.2 parts of flatting agent, 5-8 parts of inorganic thixotropic thickener, 1.2-2.4 parts of composite dispersing agent, 20-30 parts of calcined kaolin, 21-25 parts of redispersible rubber powder and 1.5-1.8 parts of mildew-proof bactericide.
Further, the modified cellulose is a mixture of cellulose inorganic acid ester, carboxymethyl cellulose and hydroxypropyl methyl cellulose, and the mass ratio of the cellulose inorganic acid ester to the carboxymethyl cellulose to the hydroxypropyl methyl cellulose is 1:1.2-1.8: 2.
Further, the compound dispersing agent is a mixture of sodium phosphate and sodium tripolyphosphate, and the mass ratio of the compound dispersing agent to the sodium tripolyphosphate is 2-3: 1.
Further, the particle size of the gravel at the midstream of the river is 40-100 meshes, wherein the proportion of 60 meshes or less accounts for 80%.
Furthermore, the inorganic thixotropic thickener is one of ATT-50, AT-33 and FDSS-5.
Furthermore, the redispersible rubber powder is a mixture of a lauric acid ethylene grafted tertiary carbonate ethylene copolymer and an organic silicon grafted ethylene-acetic acid copolymer, and the mass ratio of the lauric acid ethylene grafted tertiary carbonate ethylene copolymer to the organic silicon grafted ethylene-acetic acid copolymer is 1-3: 1.
Further, the flatting agent is one or more of a pure acrylic flatting agent, a fluorine modified acrylic flatting agent, a phosphate modified acrylic flatting agent and organic modified polysiloxane.
Furthermore, the leveling agent is a mixture of a phosphate modified acrylic leveling agent and organic modified polysiloxane, and the mass ratio of the phosphate modified acrylic leveling agent to the organic modified polysiloxane is 1: 2-3.
Furthermore, the mildew-proof bactericide selects one of JF-90, poly 2-methyl-4-isothiazoline-3-ketone compounds and poly 5-chloro-2-methyl-4-isothiazoline-3-ketone compounds.
A preparation method of a batch scraping type sand wall texture coating comprises the following steps:
(1) adjusting the stirring speed to 200-one-step stirring at 500r/min, adding water, modified cellulose, a dispersing agent, a defoaming agent, titanium dioxide, a propylene glycol methyl ether acetate film-forming aid, glycerol, a pure acrylic emulsion, fumed silica, dibutyl phthalate, a leveling agent, an inorganic thixotropic thickener, a composite dispersing agent, redispersible rubber powder and a mildew-proof bactericide into a reaction kettle, adjusting the rotation speed to 800-one-step stirring at 1000r/min, and continuously stirring for 20-30 min;
(2) adjusting the stirring speed to 300-; and continuously stirring for 20-30min to obtain the batch scraped sand textured coating.
The technical scheme adopted by the invention has the beneficial effects that:
the river midstream gravel is adopted, the surface of the river midstream gravel is usually in an arc shape after being washed by flowing water, and after edges and corners do not exist, the resistance in the construction process is reduced, the construction efficiency is improved, in addition, the raw materials of the river midstream gravel are easy to obtain, the cost is low, the production cost is obviously reduced, meanwhile, the leveling agent is also added, the flatness of the coating can be improved, the phenomena of shrinkage prevention, orange peel prevention, sagging prevention and the like are included, the surface tension between the coating and the substrate can be reduced, and the coating has good wettability to the substrate; the volatilization speed of the solvent is adjusted, the viscosity is reduced, the fluidity of the coating is improved, and the leveling time is prolonged; a very thin monolayer is formed on the surface of the coating film to provide uniform surface tension, thereby improving the batch effect of batch-scraping the gritty feel coating.
The plasticizer dibutyl phthalate is added in the invention, so that the strength of the coating film layer can be improved, and the spraying effect of the coating can be improved.
The composite dispersant in the invention adopts the mixture of sodium pyrophosphate and sodium tripolyphosphate, which can improve the system stability of the coating, and the sodium pyrophosphate can be used as a water softener, because the common water used for producing the water-based coating is usually high in hardness, and the addition of the sodium pyrophosphate can reduce the hardness of the water, and can be used as a dispersant and an emulsifier: sodium pyrophosphate has a deflocculation effect and plays an emulsification effect with the coating to improve the stability of the water-based coating; the aqueous solution of sodium tripolyphosphate is alkalescent (the pH value of 1% aqueous solution is about 9.7), and the aqueous solution of sodium tripolyphosphate forms suspension (similar to emulsion) in water with the pH value of 4.3-14, and the sodium tripolyphosphate can also make liquid and solid particles better dissolved in a liquid (such as water) medium, so that the sodium tripolyphosphate and the solid particles are mixed to be used as a dispersing agent, the system stability of the coating is improved, and the coating effect of the coating is improved.
According to the invention, by adding the inorganic thixotropic thickener, the addition amount of cellulose can be reduced, a paint film can be prevented from sagging, paint splashing in the coating process of the paint can be prevented, pigment deposition in the storage process of the paint can be prevented, liquid layering of the paint can be improved, and the appearance of the paint is uniform and consistent.
