Water-borne colorful building coating resistant to coloring colloid adhesion and preparation method of water-borne colorful building coating

Abstract

The invention relates to a water-borne colorful building coating resistant to coloring colloid adhesion. The coating comprises a continuous phase and a disperse phase. The continuous phase includes a continuous phase emulsion, a film-forming auxiliary agent, a bactericide, a multifunctional auxiliary agent, a thickening agent, an antifoaming agent, an antifreezing agent, an anti-adhesion agent, and deionized water. The disperse phase comprises a disperse phase emulsion, hydroxyethyl cellulose, inorganic pigment, colorful special-purpose color paste, a filling material, a dispersant, an antifoaming agent, a multifunctional auxiliary agent, a film-forming auxiliary agent, an antifreezing agent, a thickening agent, a stabilizer, a super rheological auxiliary agent solution with the concentration of 6.0%, a bactericide, and deionized water. The pH of the coating is 8.0-9.5. The invention further relates to a preparation method of the water-borne colorful building coating. According to the coating and method, the repeatability of a production process, the stability in a product storage process, convenience of a product construction process and simulation degree of a product are improved.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a water-based colorful architectural coating, in particular to a colored colloid anti-blocking water-based colorful architectural coating and a preparation method thereof. Background technique [0002] As a new type of architectural coating product developed in recent years, water-based colorful architectural coatings are widely used in architectural engineering decoration due to their convenient construction and good environmental protection. However, there are many influencing factors in the production process of the existing water-based colorful architectural coatings on the market. The existing technology is still unable to list all the influencing factors and master the mature control methods of each influencing factor, so the repeatability of the production process is poor, especially for coloring. Colloidal adhesion often occurs, causing even if the same raw...

AI Technical Summary

Problems solved by technology

Existing companies of this type of products have strict regulations on production, transportation, storage, and construction conditions. However, even if existing products that meet the above technical requirements and implement various management regulations During the process, the phenomenon of coloring colloid sticking occurs from time to time, which eventually leads to poor repeatability in the production process and construction process, and directly fails to produce or construct

Even if such products on the market can be constructed, due to the existence of the adhesion of colored colloids, the degree of simulation is significantly reduced, and it has no use value.
