Abstract

The invention discloses an antibacterial powder coating and a production technological method thereof. The antibacterial powder coating comprises, by weight, 40-50 parts of epoxy resin, 20-30 parts of polyester resin, 10-20 parts of antibacterial agent, 5-15 parts of titanium dioxide, 2-9 parts of iron oxide red, 3-10 parts of nanofiller, 2-7 parts of curing agent and 4-12 parts of flatting agent. The antibacterial powder coating prepared through the method is good in bactericidal performance, environmentally friendly, free of pollution, high in film hardness, high in adhesive force, simple in production technological method and suitable for the fields of kitchens, household appliances, food industrial equipment, medical treatment and the like by using the raw materials of the rational proportion.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an antibacterial powder coating and a production process thereof. Background technique [0002] With the increasing variety of coating products and the continuous expansion of the application range, the coating industry has become an important independent industrial production part of the chemical industry. In order to reduce the pollution to the atmosphere, the control of pollution sources by environmental laws and regulations is becoming increasingly strict, requiring the development of pollution-free and resource-saving coating varieties. Therefore, solvent-free, protective and decorative powder coatings have developed rapidly because of their economic and social benefits. [0003] However, the defects of the antibacterial powder coatings currently on the market are: poor antibacterial and antifungal effects, short duration, poor compatibility with the main film-forming substances in ...
