Application of expanded glass beads in sand-in-water base paint, sand-in-water base paint, preparation method and sand-in-water coating

Abstract

The invention relates to application of expanded glass beads in sand-in-water base paint, the sand-in-water base paint, a preparation method and a sand-in-water coating. The sand-in-water base paint is prepared from components in parts by weight as follows: 20-30 parts of deionized water, 0.2-0.3 part of a dispersing agent, 0.2-0.5 part of a defoaming agent, 1.0-2.0 parts of an anti-freezing agent, 1.0-2.0 parts of a coalescing agent, 1-5 parts of expanded glass beads, 1-5 parts of titanium dioxide, 1-8 parts of kaolin, 0.8-2.0 parts of cellulose, 1.0-2.0 parts of a pH regulator, 20-40 parts of an emulsion, 0.1-0.5 part of a preservative, 5-10 parts of a 10wt% protective glue solution, 0.1-0.5 part of a thickening agent and 40-50 parts of quartz sand. The expanded glass beads are added tothe sand-in-water base paint, the specific gravity of particles in the sand-in-water base paint is reduced, the suspension property of particles in the base paint is improved, so that the particle suspension property in the sand-in-water coating prepared from the sand-in-water base paint is improved, the size of sand-in-water particles in shear and granulation processes is more uniform, the coverage rate of finished sand-in-water products is increased, and the spray consumption of the sand-in-water coating is reduced.

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 exterior 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
