Problems solved by technology

[0005] The research topic of reducing the VOC content of coatings to a lower level without affecting the main performance of coatings has always been the subject of exploration and advancement in the global coatings industry, but in some ultra-low VOC products in the same industry, the reduction of VOCs will also cause coatings. The performance of the
[0006] In addition, due to the deterioration of the environment and serious ecological damage, the natural immune function of the human body is reduced; at the same time, various epidemic diseases are spreading rapidly, so people's demands for antibacterial functions of coatings are also getting higher and higher.

Abstract

The invention discloses a preparation method of an antibacterial environmentally-friendly interior wall coating. The preparation method is characterized in that a film forming material adopted in the preparation method is a combination of an acrylic copolymer emulsion with diacetone activity functional groups and an acrylic copolymer emulsion with functional groups capable of stably complexing silver ions, so that the film forming property of the interior wall coating is excellent; special functional groups on molecular chains of the emulsion polymers can be complex with the silver ions to form a stable compound; meanwhile, the silver ions are safe, efficient and environmentally-friendly inorganic antibacterial agents, so that the coating has certain antibacterial property; other additives do not contain APEO (alkylphenol ethoxylates), limited metals and VOC (volatile organic compounds), so that the content of a prepared organic volatile substance approaches zero, and meanwhile, the other additives have synergistic interaction effects when being compounded to the coating; attapulgite and diatomite serve as packing and have certain effects on organic substance adsorption apart from having effects owned by the coating, so that the coating is relatively environmentally-friendly.

Description
