Abstract

The invention relates to the technical field of coatings, and particularly discloses a base paint and a Macai stone coating. The basic paint comprises, by weight, 0.4-2 parts of cellulose, 5-10 parts of a protective glue aqueous solution, 30-50 parts of a silicone acrylic emulsion, 5.8-21.1 parts of an additive, and 30-50 parts of deionized water, wherein the protective glue aqueous solution comprises, by weight, 85-95 parts of deionized water, 1-10 parts of a basic glue material, and 1-10 parts of a reinforcing glue material, the basic rubber material is LAPONITE-S482, and the reinforcing glue material is GT-R, GS, LAPONITE-RD or R105. The Macai stone coating prepared in the invention has relatively high strength and toughness, the qualified rate of color points can reach 87% or above under the air pressure of 0.6 MPa, the highest qualified rate is 99%, and color points are relatively uniform in size, free of color bleeding and clear.

Description

technical field [0001] The application relates to the technical field of coatings, more specifically, it relates to a base paint and a hemp-colored stone coating. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments, fillers, and adding corresponding Auxiliary, a viscous liquid formulated with organic solvents or water to form a functional protective layer. [0003] In terms of coating selection, hemp colored stone paint is the most widely used paint in China. Hemp colored stone paint includes base paint, granulation liquid and continuous phase. At present, the main construction method is to spray hemp colored stone paint with spray gun. On the surface of the object to be protected, the spray gun generally uses a sand-in-water spray gun and a real stone paint spray gun to s...
