Abstract

The invention discloses a wear-resistant and anti-static antibacterial paint and a preparation method thereof. The method includes the following steps that 1, a film-forming substance is dissolved in a solvent, and after uniform mixing, a film-forming substance solution is obtained; 2, 10-20 parts of an antibacterial composite is taken and added into 1 / 3 of the film-forming substance solution, high-speed dispersion is carried out for 60-90 min, and antibacterial dispersion liquid is obtained; 3, 10-20 parts of conducting filler is taken and added into 1 / 3 of the film-forming substance solution, high-speed dispersion is carried out for 60-90 min, and conducting dispersion liquid is obtained; 4, the antibacterial dispersion liquid and the conducting dispersion liquid are added into 1 / 3 of the film-forming substance solution, high-speed dispersion is carried out for 60-90 min, 3-5 parts of a dispersing agent, 1-5 parts of a flattening agent, 1-3 parts of a defoaming agent and 1-5 parts of an anti-settling agent are added in sequence, and after high-speed uniform dispersion, the wear-resistant and anti-static antibacterial paint is obtained. The paint has excellent antibacterial performance, anti-static performance and wear-resistant performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wear-resistant, antistatic and antibacterial coating and a preparation method thereof. Background technique [0002] For the metal surface casing of electronic and electrical equipment, or the surface metal casing of various radiators, due to long-term exposure to the air, it is easily corroded by oxygen and moisture in the air, resulting in corrosion and rust, and the rust of the metal surface casing It affects the normal operation and beautiful appearance of these electronic and electrical equipment, or various radiators. Therefore, it is necessary to coat the metal shell with paint for protection. However, traditional ordinary coatings are usually insulator coatings with high resistivity, so that the electronic and electrical equipment or the surface shell of the radiator will gradually accumulate static electricity during daily use. The static electricity on the coating o...
