Application of expanded vitrified microspheres in sand-in-water base paint, sand-in-water base paint, preparation method and sand-in-water coating

Abstract

The present invention relates to the application of expanded vitrified microspheres in sand-in-water base paint, sand-in-water base paint, preparation method and sand-in-water paint. The sand-in-water base paint is prepared from the following components by weight: 20-30 parts of ionized water, 0.2-0.3 parts of dispersant, 0.2-0.5 parts of defoamer, 1.0-2.0 parts of antifreeze, 1.0-2.0 parts of coalescence aid, 1-5 parts of expanded vitrified microbeads, titanium dioxide 1-5 parts, 1-8 parts of kaolin, 0.8-2.0 parts of cellulose, 1.0-2.0 parts of pH regulator, 20-40 parts of emulsion, 0.1-0.5 parts of preservative, 5-10 parts of 10wt% protective colloid solution, 0.1-0.5 parts of thickener and 40-50 parts of quartz sand; add expansion vitrified microbeads in the sand-in-water base paint, reduce the proportion of particles in the sand-in-water base paint, improve the suspension of particles in the base paint, and make The suspension of particles in the sand-in-water coating prepared by it is improved, which makes the size of the sand-in-water particles more uniform during the shear granulation process, improves the coverage of the finished sand-in-water coating, and reduces the spraying consumption of the sand-in-water coating. quantity.

Description

technical field [0001] The invention relates to the technical field of imitation stone materials for building exterior walls, in particular to the application of expanded vitrified microbeads in sand-in-water base paint, the sand-in-water base paint, a preparation method and the sand-in-water paint. Background technique [0002] With the rapid development of exterior wall coatings, various coating names began to appear, such as water in water, sand in water, texture paint, real stone paint and so on. Water-in-water, sand-in-water, and real stone paint are all stone-like paints, which have the characteristics of imitating marble, natural stone, and granite, and are ideal substitutes for dry-hanging stone on external walls. [0003] Real stone paint is also called "stone paint, imitation stone paint". It is mainly made of natural colored sand and emulsion additives. It has weather resistance, crack resistance, safety and environmental protection. It is not as good as water-in...

AI Technical Summary

Problems solved by technology

Although the real stone paint has the natural stone texture of litchi surface, it cannot achieve the colorful visual effect of imitation marble, while the water-in-water colorful paint has surface luster, but it does not have the texture of natural stone with litchi surface.

[0005] However, due to the large proportion of sand-in-water particles, the particles tend to sink to the bottom when shearing and granulating the toned slurry, and it is not easy to shear the particles evenly; after the finished product sand-in-water is stored after granulation, Delamination will occur due to its large specific gravity, which will make the spraying uniformity of the product poor and affect the spraying effect
