Problems solved by technology

[0002] Interior wall coatings are an important part of building decoration materials. There are many manufacturers and many brands of products, but most of them still have weak coatings, weak adhesion, easy peeling off coatings, poor scrub resistance and durability. Contamination is not good, formaldehyde and other harmful substances greatly exceed the national limit standards and other deficiencies
To improve the performance and quality of interior wall coatings, many people have done exploratory work, and some people use the method of adding nano-components to improve the quality of interior wall coatings, but the improvement effect is not obvious

Abstract

The invention discloses environment-friendly internal wall paint and a preparation method thereof. The paint is prepared from the following raw materials including styrene-acrylic emulsion, polyvinyl alcohol resin, silica sol, sodium naphthenate, polyoxyethylene, talcum powder, modified diatomite powder, rosin glycerin ester, polyvinyl alcohol, dispersing agents, wetting agents, leveling agents, defoaming agents and coalescing agents. According to the preparation method, firstly, water is added into the styrene-acrylic emulsion, the polyvinyl alcohol resin, the silica sol, the talcum powder and the modified diatomite powder; uniform mixing is performed to obtain slurry A; then, the sodium naphthenate, the polyoxyethylene, the rosin glycerin ester and the polyvinyl alcohol are added into slurry A to be uniformly mixed for obtaining slurry B; finally, the rest raw materials are added into the slurry B. The environment-friendly internal wall paint has the advantages that the preparation is simple and convenient; green and environment-friendly effects are achieved; harmful substances such as formaldehyde are not contained; in addition, the bonding force is strong; the wiping-resistant performance, the waterproof and flame-retardant performance and the leveling performance are good; the cost is low; the shelf life is long; the paint belongs to a new generation of internal wall paint environment-friendly products.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to an environment-friendly interior wall coating and a preparation method thereof. Background technique [0002] Interior wall coatings are an important part of building decoration materials. There are many manufacturers and many brands of products, but most of them still have weak coatings, weak adhesion, easy peeling off coatings, poor scrub resistance and durability. Contamination is not good, formaldehyde and other harmful substances greatly exceed the national limit standards and other deficiencies. To improve the performance and quality of interior wall coatings, many people have done exploratory work, and some people use the method of adding nanometer components to improve the quality of interior wall coatings, but the improvement effect is not obvious. [0003] Diatom powder is a kind of siliceous rock powder with neutral pH value, non-toxic, strong adsorptio...
