A kind of water-based lychee surface stone material effect coating and preparation method thereof

Abstract

The invention discloses a water-based litchi-surface-stone-effect paint which comprises a component A, a component B and a component C, wherein the component A is composed of an organic silicon modified elastic emulsion, sodium polyacrylate, ethoxylated acetylene diol, emulsified mineral oil, hydroxyethyl cellulose ether, propanediol, organic modified laminar hectorite, sintered quartz sand, water, 2-amino-2-methyl-1-propanol and dimethyl phthalate; the component B is composed of organic modified laminar hectorite and deionized water; and the component C is composed of self-crosslinked matt organic silicon emulsion, lauryl alcohol ester and water. The paint has the self-crosslinking function and self-thickening property, and has the advantages of favorable water resistance, favorable acid / alkali resistance and excellent weather resistance. The product is flaky with colored points, and is diversified.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a water-based lychee surface stone effect coating and a preparation method thereof. Background technique [0002] As a natural stone, limestone is more and more widely used in the exterior wall decoration of modern high-end buildings. The imitation limestone effect coating is a new type of architectural coating. More than 80%, and has particularly excellent water resistance, weather resistance and other characteristics, can be widely used in high-end office buildings, villas and other buildings for exterior wall finishing, the market prospect is broad. But the use effect material of the imitation limestone coating used in the prior art is relatively poor, and the coating that forms will crack in a short time, affects attractive in appearance, and the coating layer that forms is well-defined, is difficult for relative penetration, and use effect is relatively poor. Poor...

AI Technical Summary

Problems solved by technology

However, the use effect material of the imitation limestone coating used in the prior art is relatively poor, and the coating formed will crack in a short time, which affects the appearance. Poor, in the production process, it is often necessary to add various additives to cause the paint to crosslink and thicken, but the weather resistance of the paint is reduced from the side. In addition, the flakes produced in the prior art are relatively single and cannot Multi-faceted production, poor scope of application
