Abstract

The invention relates to the technical field of coatings, and provides a sand-in-water multicolor coating and a preparation method thereof. The sand-in-water thermal insulation coating provided by theinvention comprises base paint, a protective glue solution and a continuous phase, wherein the base paint is prepared from the following components in parts by weight: 0.6-0.65 part of cellulose, 0.5-1 part of inorganic color paste, 40-50 parts of quartz sand, 3.5-4 parts of a filler, 2.5-3 parts of acrylic emulsion, 10-11 parts of silicon dioxide dispersion liquid, 0.3-0.4 part of protective glue and 30-36 parts of water. The sand-in-water multicolor paint has good stability and long storage period, meets the requirements of inorganic paint standards for buildings on the content of macromolecular organic matters, and can meet the requirements of energy conservation, environmental protection, safety, fire prevention and the like, so that a formed paint film has rich and full patterns, high simulation degree and vivid stone effect.

Description

technical field [0001] The application belongs to the technical field of coatings, in particular to a sand-in-water multi-color coating and a preparation method thereof. Background technique [0002] Water-in-sand colorful paint, also known as liquid granite paint, is a stone-like paint. Because it can produce realistic and durable granite colors, and the simulation degree can reach 99%, it is often used to prepare granite-like interior and exterior walls. [0003] Sand-in-water multi-color coatings are formed by dispersing the colored dispersed phase in the continuous phase. The coating system includes pigments, quartz sand, fillers, film-forming substances and protective glue. Since the film-forming substances currently used in coatings are mainly organic substances, organic film-forming substances Poor compatibility with inorganic substances such as pigments, quartz sand, fillers, etc., makes the sand-in-water colorful coatings generally poor in stability and short in sto...
