Problems solved by technology

Although the combination of styrene-acrylic emulsion and vinegar-acrylic emulsion can improve the weather resistance of the composite rock slice, the improvement of the tensile strength and liquid absorption rate of the composite rock slice is limited, and the emulsion in the composite rock slice formula needs to be further modified. , to meet the needs of high-quality composite rock flakes, and at the same time carry out a series of functional modifications on water-based paints to meet the needs of the development of colorful rock flake coatings for interior walls

Abstract

The invention discloses a waterborne colorful rock slice paint added with rice husk silicon nitride based porous ceramic powder. Rice husks are carbonized and then sintered with silicon nitride to obtain porous ceramic powder, the porous ceramic powder is added in paint preparation to enhance the mechanical strength and wear resistance of a coating film, and at the same time porous ceramic has small pore size, high porosity and good sound absorption effect. The colorful rock slice paint imitates the granite pattern, has the advantages of elegant appearance, excellent weather resistance, long service life, and good noise adsorption effect, can be used in walls of cinemas, theaters, subways and the like, the construction is convenient, and the use effect is excellent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based colorful rock flake coating added with rice husk silicon nitride-based porous ceramic powder. Background technique [0002] Water-based composite rock flake imitation granite paint is also called rock flake paint and granite stone paint. It is a new type of pure water-based sand wall-shaped architectural paint that does not contain any solvent-based substances. It is rich in the style of granite, the connotation of granite, the nobility of granite, and the grade of granite. , is an upgraded variety of traditional natural stone paint. With the wide application of new coatings in the construction market, the research on the formulation of composite rock slices in architectural coatings has attracted more and more attention from researchers. Water-based composite rock flake imitation granite paint is prepared from high-quality synthetic resin emulsion, colored compos...
