Problems solved by technology

[0002] Acrylic glossy emulsion paints for walls are all thin coatings. It is a thin coating made of organic polymer materials as the main film-forming substance, plus different pigments, fillers and aggregates. It is water-resistant, acid-resistant, and alkali-resistant. , freeze-thaw resistance and other characteristics, the current coatings on the market have imperfect functions and defects. The main disadvantage of this coating is that the elasticity of the coating film is easy to age, resulting in a decrease in elongation, and it cannot effectively protect the strength of the bottom layer of the wall. As a result, the wall surface cracks and falls off, which not only affects the appearance of the building, but also causes the wall surface to crack and cause water leakage on the wall surface.

Abstract

The invention discloses a self-cleaning coating, which is composed of the following raw materials by weight: 52.1-60 parts of acrylate emulsion, 0.1-0.2 part of 2, 4-dimethyl acetophenone, 0.6-1 part of ureido propyltriethoxysilane, 0.4-1 part of zinc oxide, 0.4-1 part of methylparaben, 4-6 parts of illite powder, 14-18 parts of titanium white, 2-3 parts of Poly (butyl acrylate), 1.3-2 parts of 2-amino-2-methyl-1-propanol, 1.3-2 parts of ethylene bis stearamide, 5-7 parts of a film forming assistant and 26-40 parts of deionized water, the self-cleaning coating is long-lasting in stain resistance, can achieve the self-cleaning effect through the rain washing, is especially suitable for building exterior wall coatings, the coating stability is strong, antibacterial anti-corrosive properties are good, and the comprehensive quality is high.

Description

technical field [0001] The invention mainly relates to the field of coatings, in particular to a self-cleaning coating. Background technique [0002] Acrylic glossy emulsion paints for walls are all thin coatings. It is a thin coating made of organic polymer materials as the main film-forming substance, plus different pigments, fillers and aggregates. It is water-resistant, acid-resistant, and alkali-resistant. , freeze-thaw resistance and other characteristics, the current coatings on the market have imperfect functions and defects. The main disadvantage of this coating is that the elasticity of the coating film is easy to age, resulting in a decrease in elongation, and it cannot effectively protect the strength of the bottom layer of the wall. As a result, cracking and falling off of the wall surface not only affects the appearance of the building, but also cracks the wall surface, causing water leakage on the wall surface.
