Problems solved by technology

[0003] The existing white and other light-color real stone paints are prone to yellowing and other color deepening problems with the increase of use time
The reasons are as follows: 1. Because the surface microstructure of real stone paint is uneven and the paint film is not dense, solid particles such as dust are easy to accumulate on the surface, which is easy to cause contamination and yellowing problems.
2. The acrylic emulsion used as a binder in the base material, especially the styrene-acrylic emulsion, after being irradiated by ultraviolet rays, its benzene ring is easily oxidized to quinone and yellows, and even decomposes in severe cases, causing sand loss and other problems

Abstract

The invention provides a yellowing-resistant real stone paint. The yellowing-resistant real stone paint comprises, by mass, 60-90 parts of natural quartz sands, 0.5-1.2 parts of an aqueous titanium dioxide slurry, 7-20 parts of a waterproof white emulsion, 5-10 parts of ethylene glycol butyl ether, 3-9 parts of xylene, 2-9 parts of an antibacterial agent, 10-15 parts of a silicone-acrylic emulsion, 3-6 parts of a thixotropic agent, 2-6 parts of a thickener, 0.4-1 part of a film forming assistant, 1-5 parts of calcium chloride and 20-50 parts of water. The yellowing-resistant real stone paint has the advantages of effective improvement of the waterproof property of a paint film, prevention of the stain and yellowing of the surface of the paint film, caused by dusts and other solid particles penetrating the paint film with water, improved storage stability and improved construction performance; and the waterproof white emulsion adopts an acrylate copolymer, soap-free emulsion polymerisation and surface cross-linking technology treatment are adopted, and the waterproof white emulsion is a film forming material, and provides very good waterproof whiteness and weatherability.

Description

technical field [0001] The invention belongs to the field of real stone paint research and development, and in particular relates to a yellowing-resistant real stone paint and a preparation method thereof. Background technique [0002] As a new type of environmentally friendly building material, real stone paint has occupied an important position in the field of exterior wall engineering coating, gradually replacing traditional decorative materials such as ordinary stone, and it will continue to maintain this advantage in the future, with broad market prospects. [0003] Existing white and other light-color real stone paints are prone to color deepening problems such as yellowing as the use time increases. The reasons are as follows: 1. Because the microstructure of the real stone paint is uneven and the paint film is not dense, solid particles such as dust are easy to accumulate on the surface, which is easy to cause contamination and yellowing. 2. The acrylic emulsion use...
