Problems solved by technology

However, due to the increasingly fierce competition in the real stone paint market, in order to compete with their peers and increase profits, many real stone paint manufacturers and construction parties do not carry out surface treatment after the construction of the real stone paint. It will soon become gray, the color of the real stone paint is obviously different from that at the beginning of construction, and the coating is not easy to wash off, which affects people's perception of the appearance of the building. produce bad mood

Abstract

The invention provides a stain-resistant pure acrylic natural stone paint emulsion which comprises the following components in parts by weight: 50-80 parts of alkyl methacrylate, 30-40 parts of alkyl acrylate, 0.7-1.4 parts of acrylic acid, 0.5-0.8 part of methacrylic acid, 0.6-1.6 parts of silane coupling agent, 0.5-0.9 part of initiator, 0.9-1.6 parts of emulsifier and 90-120 parts of deionized water. The molecular structure is divided into to a hydrophilic layer and a hydrophobic layer by a core-shell technique, so that the emulsion particles form a structure with a hydrophilic inner layer and a hydrophobic outer layer; silane molecules in the silane coupling agent are coated on the emulsion particle surface under the mutual association and oligomerization actions; and in the paint film forming process, a compact hydrophobic layer is formed on the paint film surface, so that the paint film has excellent hydrophobicity, and effectively prevents the pollutants from being attached to the paint film surface and influencing the beautiful appearance of the paint film. The pure acrylic natural stone paint emulsion has the characteristics of stain resistance, favorable paint film hardness, favorable water resistance, favorable yellowing resistance, stable paint properties and the like.

Description

technical field [0001] The invention relates to an emulsion additive added to real stone paint for construction, in particular to a stain-resistant pure acrylic real stone paint emulsion obtained by optimally copolymerizing acrylic acid and methyl methacrylate and a preparation method thereof. Background technique [0002] In recent years, because the decorative effect of real stone paint is similar to that of marble and granite, buildings decorated with real stone paint have natural and real natural luster, giving people a sense of elegance, solemnity and harmony, and are suitable for the decoration of interior and exterior walls of buildings. Real stone paint has fire protection, waterproof, acid and alkali resistance, and pollution resistance. Non-toxic, tasteless, strong adhesion, never fade and other characteristics, can effectively prevent the external harsh environment from eroding the building, prolong the life of the building, because the real stone paint has good a...
