Problems solved by technology

[0003] Conventional sand-in-water imitation stone coatings have the following problems in production and use: 1. Poor aging resistance: because the color points in the water-in-sand are toned by colorants, some organic colorants, such as phthalocyanine blue, bright red, and lemon yellow Such as poor aging resistance, resulting in poor aging resistance of sand-in-water coatings and easy to fade; 2. Long production time: sand-in-water is composed of different color points, and each color point needs to be manually added color paste for color matching; 3. There are hidden dangers in the stability of th

Abstract

The invention provides a stone-imitating coating and a preparation method thereof. The stone-imitating coating includes, by weight, 300-500 parts of deionized water, 2-3 parts of a sterilizing agent,2-5 parts of cellulose, 1-2 parts of a dispersant, 2-4 parts of a defoaming agent, 7-10 parts of a film forming additive, 7-10 parts of propylene glycol, 1-3 parts of a pH regulator, 150-200 parts ofa binder, 2-4 parts of a thickener, 300-500 parts of sintered colored sand, and 5-15 parts of protective glue. The sintered colored sand is made from quartz sands in 40-120 meshes, toner percentage being 0.8-1.2%. By using the sintered colored sand instead of calcium carbonate sand, regulating raw material ratio and optimizing process parameters, the coating has excellent performance, good stability and good anti-aging effect. The preparation method has simple process and can achieve industrial large-scale production; the product brings excellent economic benefit to enterprises and has extensive prospect.

Description

Technical field [0001] The invention relates to the field of coatings, and mainly relates to an imitation stone coating and a preparation method thereof. Background technique [0002] Sand-in-water imitation stone paint is a common decorative paint on the market at present. Its decorative effect is similar to natural stone. Compared with natural stone, it has the characteristics of low cost, small wall load, easy renovation and maintenance. Sand-in-water coatings are mainly made of natural quartz sand, calcium carbonate sand, polymer emulsion and related additives. Using the principle of steric hindrance and charge repulsion, different color points are prepared. The construction method is colorful paint spray gun spraying, and its decorative effect is similar to natural stone. Compared with natural stone, it has the characteristics of low cost, small wall load, easy renovation and maintenance. [0003] Conventional sand-in-water imitation stone coatings have the following problem...
