Abstract

The invention discloses a plastic part surface antibacterial mildew-proof coating and a preparation method thereof. The coating comprises 30-40 parts of potash water glass, 0.5-1 part of sodium hexametaphosphate, 2-3 parts of zinc oxide, 4-6 parts of copper oxide, 20-30 parts of a vinyl chloride-vinylidene chloride copolymer emulsion, 15-20 parts of an ethylene-propylene emulsion, 2-5 parts of anantibacterial mildew inhibitor, 0.5-2 parts of a hardening wear-resistant agent, 0.5-2 parts of a scratch-resistant agent, 2-5 parts of a salt spray resistance additive, 0.1-1 part of a leveling agent, 1-3 parts of a dispersant and 4-8 parts of a solvent. According to the invention, the antibacterial mildew inhibitor is arranged, so that the prepared coating has antibacterial and mildew-proof properties; the hardening wear-resistant agent is arranged, so that the prepared coating has good wear-resisting performance; by arranging the scratch-resistant agent, the prepared coating has good anti-scraping performance.

Description

technical field [0001] The invention relates to the technical field of antibacterial plastic parts, in particular to an antibacterial and mildew-proof coating on the surface of plastic parts and a preparation method thereof. Background technique [0002] The surface of electric tool products currently on the market does not use antibacterial and antifungal coatings. If there are harmful microorganisms on the surface of the coating, they will infect various diseases after contact with the human body. Pathogenic microorganisms such as bacteria are one of the main killers of human health and threaten human health. The application of antibacterial materials is still almost a blank field. As electric tools are in contact with hands for a long time, as human beings pay more attention to their own health, the tools we use every day are getting more and more attention. Contents of the invention [0003] The object of the present invention is to provide an antibacterial and antif...
