Abstract

The invention discloses a sand-in-water granite-imitating coating and a preparation method thereof. The sand-in-water granite-imitating coating comprises the following components in percentage by mass: 10-20% of a protective glue, 60-70% of mixed color points and 20-30% of coating gloss oil, wherein the mixed color points comprise, by mass, 1-3 parts of a suspending agent and 0.3-1 part of a thickening agent; and the coating gloss oil comprises, by mass, 0.3-1 part of a thickening agent; the suspending agent is hollow plastic microbeads; and the thickening agent is an associative waterborne polyurethane thickening agent. The sand-in-water granite-imitating coating disclosed by the invention has the advantages that 1, the sand-in-water granite-imitating coating has a stable reticular coating structure, and the storage stability is greatly improved; and 2, the problem of poor granulation texture is solved, and the sand-in-water granite-imitating coating has the advantages of full granulation, strong three-dimensional textures, high simulation degrees, good decorative effects and the like.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a sand-in-water imitation granite coating and a preparation method thereof. Background technique [0002] With the development of economy and the progress of society, consumers tend to pursue the elegant and solemn natural beauty of buildings, and natural granite is often used for decoration of exterior walls. However, natural granite patterns are limited in color, heavy in weight, troublesome in construction, high in cost, and may fall off over time; in addition, long-term mining will also cause exhaustion of resources and damage to the ecological environment. To this end, people have developed various artificial granite coatings to achieve the effect of natural stone. Among them, the excellent performance of water-based colorful paint and the high simulation of stone endow it with a broad application field. Water-in-water colorful paint adopts the wrappi...
