Sand-in-water type granite-imitating coating and preparation method thereof

Abstract

The invention provides a sand-in-water type granite-imitating coating and a preparation method thereof, and relates to the field of architectural coating; the sand-in-water type granite-imitating coating comprises the following raw materials in parts by weight: 1400-1600 parts of water, 8-15 parts of a preservative, 10-15 parts of hydroxyethyl cellulose, 2-5 parts of ethylene glycol, 1-3 parts ofa pH regulator, 3-5 parts of a defoaming agent, 2-5 parts of an anionic wetting agent, 2-5 parts of a dispersant, 10-20 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 5-10 parts of rutile titanium dioxide, 70-80 parts of kaolin, 300-350 parts of an acrylic emulsion, 180-220 parts of lithium magnesium silicate, 5-10 parts of snow white sand, 5-10 parts of a color paste, and 4-12 parts ofother auxiliary agents. The sand-in-water type granite-imitating coating has the advantages of rich and full patterns, strong stereoscopic texture, high simulation degree, good decorative effect andthe like, and a coating film has high strength and good weather resistance.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a sand-in-water imitation granite coating and a preparation method thereof. Background technique [0002] Coatings refer to materials that are coated on the surface of objects, can bond with the substrate and form a complete and tough protective film. Coatings usually use resin, oil or emulsion as the main component, and may add pigments, fillers, additives and other components, and are formulated with organic solvents or water. Coatings belong to organic chemical polymer materials, and the formed paint film belongs to the type of polymer compounds. At the effect level, the use of coatings can not only protect the items, but also give the items color and luster, so as to play a decorative role. . [0003] Natural stone is a common material for architectural decoration. Its appearance is exquisite and its quality is high. It can beautify the building and improve the decorat...

Problems solved by technology

Water-in-water colorful paint is environmentally friendly and light in weight. It has its unique advantages in imitating smooth granite. However, because of its low concave-convex feeling, to imitate the effect of rough granite, real stone paint or brushed aggregates are needed as the supporting middle layer. Increased the complexity of the construction, but also increased the construction cost

In addition, the water-in-water multi-color coatings of the prior art often lose the strength of the aggregate component in order to pursue the realistic texture, and the selection of bonding materials, anti-cracking resin and other components is not reasonable enough, which directly affects the wear resistance of the paint film. Sexuality, leading to wear and tear of the coating during use, affecting the appearance
