Problems solved by technology

[0003] In order to improve the simulation effect of frosting, the existing paint uses a large amount of pigments. Although the simulation effect is good, it causes more pollution, and it is easy to dry and crack, which is neither beautiful nor practical
and it is difficult to achieve a natural effect
[0004] Moreover, due to the unevenness of the surface, the frosted paint is easy to be stained and difficult to clean.

Abstract

The invention discloses a stain-resistant frosted coating and a preparation method thereof, belonging to the technical field of coatings. The coating comprises the following components in parts by weight: component A: water-based hydroxyacrylic acid dispersion, defoamer, pH regulator, Dispersants, pigments and fillers, substrate wetting agents, deionized water, thickeners, anti-rust additives, water-based anti-graffiti additives, film-forming additives, matting agent; and B component: amine curing agent and Propylene glycol diacetate; The stain-resistant frosted paint of the present invention has excellent surface tension and water repellency, and makes the surface of the coating film more compact simultaneously. When pollutants adhere to the coating film, due to the water repellency of the coating film The performance prevents the contamination of pollutants and the infiltration of water into the coating film, so the coating film has super stain resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a stain-resistant frosted coating and a preparation method thereof. Background technique [0002] With the advancement of science and technology and the improvement of human living standards, people have higher and higher requirements for indoor environment and air quality. In order to achieve the special effect of the interior walls and reflect the graininess of the wall surface, frosted paint is usually used. For example, the Chinese patent application with the application number CN201510332783.8 discloses a frosted coating. First, castor oil is used to crosslink the prepolymer: the multifunctional structure in castor oil can endow the polymer with a certain crosslinking ability and improve the polymer’s durability. The degree of cross-linking increases the interaction force between the molecular chains, hinders the movement of the molecular chains, and makes it difficult for...
