Abstract

The invention discloses an anti-static acrylic coating and a preparation method thereof. The anti-static acrylic coating is prepared from the following components: hydroxylated acrylic resin, terminal carboxyl polyester resin, conductive filler, polyvinyl butyral, polysiloxane, a silane coupling agent, a wetting agent, a dispersing agent, an anti-foaming agent, modified carbon fibers and deionized water. According to the anti-static acrylic coating disclosed by the invention, by using the hydroxylated acrylic resin as a base material, the terminal carboxyl polyester resin and the conductive filler are combined with the base material in a certain proportion, and auxiliaries such as the polysiloxane, the wetting agent, the dispersing agent, the anti-foaming agent, the modified carbon fibers, the polyvinyl butyral are added so as to form a formula; therefore, the excellent temperature resistance, the water resistance and the corrosion resistance of the coating are enhanced while the anti-static performance of the coating can be improved; an anti-static demand of electronic products can be met.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to an antistatic acrylic paint and a preparation method thereof. Background technique [0002] Most polymer materials are excellent electrical insulating materials, and their surface resistivity ρs (1014-1017Ω) and volume resistivity ρv (1015-1018Ω m) are very large, and they have good electrical insulation properties, but in general industrial production and In product application, the process of friction and peeling often occurs, and a large amount of static electricity is easy to accumulate, which hinders the production process and product quality, brings electrostatic hazards, and affects the use of electronic products. The use of antistatic coatings can conduct the charge on the surface of polymer materials and eliminate the accumulated charges, so as to achieve a good antistatic effect, thereby avoiding the performance problems of electronic products caused...
