Problems solved by technology

[0005] At present, the colored dots of water-in-sand on the market are all small and medium dots, and their sizes are basically below 6mm. It is difficult to imitate large colored dots and large patterns of stone, which limits its application.
For the imitation of this kind of stone, at present, multi-gun real stone paint is used to spray the effect of large color dots. Although the size of the color dots finally formed by this method is similar to that of stone, the simulation degree of color and texture is still difficult to break through.

Abstract

The invention relates to the technical field of stone-like materials, and in particular relates to large-color-point sand-in-water base paint, a preparation method and a large-color-point sand-in-water coating. The base paint is prepared from the following components in percentage by weight: 20-30% of deionized water, 0.2-0.3% of a dispersing agent, 0.2-0.5% of a defoaming agent, 1.0-2.0% of an anti-freezing agent, 1.0-2.0% of a coalescing agent, 1-4% of titanium dioxide, 1-6% of kaolin, 0.1-0.5% of ethyl hydroxyethyl cellulose, 0.2 to 1.0% of methyl ethyl hydroxyethyl cellulose, 1.0 to 2.0% of a pH regulator, 20 to 40% of emulsion, 0.1 to 0.5% of a preservative, 5 to 10% of a 10wt% protective glue solution, 0.1 to 0.5% of a thickener and 25 to 45% of quartz sand. The base paint has good toughness, and the prepared large-color-point sand-in-water coating has the simulation degree of sand-in-water and can meet the simulation requirements of large-color-point and large-pattern stones.

Description

technical field [0001] The invention relates to the technical field of imitation stone materials for building exterior walls, in particular to a large color dot sand-in-water base paint, a preparation method and a large color dot 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, but it is not as good as water in imitation stone effect. Water and sand in wat...
