A kind of inorganic water-in-sand colorful coating and preparation method thereof

Abstract

The invention discloses an inorganic sand-in-water colorful paint, which is prepared by mixing a protective colloid solution, a granulated base paint and a continuous phase; in parts by mass, the protective colloid solution includes 90-100 parts of deionized water and 0.1-100 parts of an anti-sedimentation agent 1 part, 1-10 parts of protective rubber powder; granulation base paint includes 25-35 parts of deionized water, 0.5-1.5 parts of cellulose ether, 1-10 parts of kaolin, 0.1-1 part of titanium dioxide, 10-30 parts of inorganic resin 1-5 parts of protective rubber powder, 0.1-0.5 parts of color paste, 30-50 parts of 80-120 mesh snowflake white; the continuous phase includes 40-70 parts of inorganic resin, 30-50 parts of deionized water, and multifunctional additives 0.1‑1 part, thickener 0.5‑1 part. The inorganic sand-in-water multicolor coating prepared by the invention meets the standard that the organic matter in the inorganic coating does not exceed 5%, and has excellent hardness, weather resistance, water resistance, alkali resistance and storage stability.

Description

technical field [0001] The invention relates to an inorganic sand-in-water multicolor coating and a preparation method thereof. Background technique [0002] Colorful paint is composed of incompatible two-phase components, one of which is the continuous phase of the dispersion medium, and the other is the dispersed phase. The dispersed phase is also called the base paint. It is composed of high molecular polymers and inorganic materials. Rich and colorful colored particles make the colorful paint have richer colors than traditional real stone paint, and more realistic imitation granite effect. However, due to the limitation of existing technology, multi-color coatings in the market have poor hardness and water resistance. After construction, encountering rainy days or high humidity climates will cause quality accidents such as white spots and easy to fall off. Traditional coatings contain certain voc additives. In recent years, inorganic coatings have become more and more p...

Problems solved by technology

However, due to the limitation of existing technology, multi-color coatings in the market have poor hardness and water resistance. After construction, encountering rainy days or high humidity climates will cause quality accidents such as white spots and easy to fall off. Traditional coatings contain certain voc additives. In recent years, inorganic coatings have become more and more popular due to their environmental protection, but conventional inorganic coatings have the disadvantages of poor stability and easy cracking of film formation.
