Problems solved by technology

[0003] However, during the spraying process of the existing texture paint, gravel, stone particles and stone powder will be sprayed out at a very high speed. After the gravel, stone particles and stone powder fly out, the emulsion on the surface will dry instantly, causing it to lose its cohesiveness , affect the spraying effect of the textured paint, and also cause the coating film to fall off and fly sand

preparation example Construction

[0033] A kind of preparation method of texture coating, described preparation method comprises the following steps:

[0034] (1) Adjust the stirring speed to 200-500r / min, add water, modified cellulose, dispersant, defoamer, pigment, alcohol ester twelve film-forming aids, ethylene glycol, silicon acrylic emulsion to the reactor , elastic emulsion, inorganic thixotropic thickener, anti-mildew bactericide and redispersible rubber powder, after adding, adjust the speed to 800-1000r / min, and continue to stir for 20-30min;

[0035] (2) Adjust the stirring speed to 300-600r / min, add round sand, bentonite, and calcined kaolin to the reaction kettle, adjust the speed to 800-1000r / min, and then adjust the pH value to below 10 with ammonia water; continue stirring 20-30min to get texture paint.

Embodiment 1

[0037] A kind of texture paint, its composition by mass is as follows: 100 parts of water, 1.2 parts of modified cellulose, 1.5 parts of dispersant, 0.8 part of defoamer, 15 parts of pigment, 8 parts of alcohol ester twelve film-forming aids, ethylene glycol 10 parts of alcohol, 150 parts of silicone acrylic emulsion, 50 parts of elastic emulsion, 500 parts of round sand, 30 parts of bentonite, 10 parts of calcined kaolin, 12 parts of redispersible rubber powder, 4 parts of inorganic thixotropic thickener, anti-mold and fungicide 0.8 servings.

[0038] Wherein, the modified cellulose is selected from microcrystalline cellulose.

Abstract

The invention relates to the technical field of decorative coatings, and in particular to a texture coating and a preparation method thereof.The texture coating comprises the following components in parts by mass: 100-150 parts of water, 1.2-1.8 parts of modified cellulose, 1.5-2.5 parts of dispersant, 0.8-1.2 parts of defoamer, 15-25 parts of pigment, 8-10 parts of coalescing agent 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 10-15 parts of ethylene glycol, 150-160 parts of silicone acrylic emulsion, 50-100 parts of elastic emulsion, 500-600 parts of round grain sand, 30-80 parts of bentonite, 10-20 parts of calcined kaolin, 12-18 parts of dispersible adhesive powder, 4-6 parts of inorganic thixotropic thickener, and 0.8-1.2 parts of fungus proofing fungicide. By adding the inorganicthixotropic thickener to the texture coating, the addition amount of cellulose can be reduced, and film sagging can be prevented, preventing coating splashing in the application process; in addition,pigment deposition during the storage of the coating can be prevented and the problem of liquid layering of the coating can be ameliorated, providing uniform appearance of the coating.

Description

technical field [0001] The invention relates to the technical field of decorative coatings, in particular to a textured coating and a preparation method thereof. Background technique [0002] With its infinitely varied three-dimensional textures and multiple choices of individual collocations, the texture paint presents a unique spatial perspective, which is rich and vivid, which is refreshing.
