Problems solved by technology

The preparation of the paint needs to use color paste for color matching, and the process is not simple enough
In the invention with the patent application number CN201410005877.X, a preparation method of a high-weather-resisting imitation granite water-in-water multi-color coating is disclosed. The water-based polymer synthetic emulsion is used as the base material, and various water-soluble substances are used as additives. The preparation of the finished paint also discloses the use of water-repellent additives and waterproof emulsions. However, the addition of the two is only to prevent the colorful paint from bleeding after film formation, and does not consider the water resistance, anti-pollution and Easy to clean

Abstract

The invention provides a water-in-water colorful coating and a preparation method thereof. The coating comprises a colloidal solution, a disperse phase and a continuous phase, the colloidal solution is formed by dissolving sodium pyrophosphate and magnesium lithium silicate in water, the disperse phase is mainly composed of a hydrophobic regulator, a wetting dispersant, cellulose, a pigment, the colloidal solution, an emulsion and water, and the continuous phase is mainly composed of the hydrophobic regulator, a film forming agent, an antifoaming agent, propylene glycol, a thickener, the emulsion and water, wherein the hydrophobic regulator is a divinyl benzene and 1-vinyl imidazole copolymer and / or a divinyl benzene and vinyl ionic liquid copolymer. The coating needs no organic solvents, and the waterproof property of the coating is increased through the hydrophobic regulator, so the colorful coating has the advantages of good waterproof property, bleeding resistance, stability, automatic cleaning and pollution prevention.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-in-water multicolor coating with waterproof performance and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the upsurge of interior decoration has quietly risen, and people have higher and higher requirements for the decorative effect of coatings. With its bold conception, multi-color paint breaks the traditional single-color and flat coating decoration effect, and creates a colorful and three-dimensional decorative surface, which is favored by consumers. At present, most of the colorful paints for walls in my country use oil-in-water type colorful paints. Due to the use of a large amount of organic solvents, the amount of organic solvents discharged during use is large, the production cost is high, and multiple sprayings are required during the construction process, resulting in construction speed. Slowly, it was reje...
