Description

technical field [0001] The invention relates to the technical field of conductive paint, in particular to a conductive paint and a preparation method thereof. Background technique [0002] Conductive coatings are special coatings that are coated on high-resistivity polymer materials to enable them to conduct current and eliminate accumulated static charges. They can be coated on the surface or inside of substrates of any shape. In recent years, with the rapid development of the coating industry and modern industry, a functional material is a coating that is coated on a non-conductive substrate so that it has a certain ability to conduct current and dissipate static charges. The film-forming substance is large Most are insulated. In order to make the coating conductive, a common treatment method is to incorporate conductive particles. As a conductive coating, conductive coatings have important practical value in the electronics industry, construction industry and aviation t...
