Description

technical field [0001] The invention relates to a conductive coating, in particular to a graphene conductive coating with conductivity. Background technique [0002] Automobiles are important industrial products. As an integral part of the automotive system, automotive plastic parts have a good market space. In order to prevent problems such as high cost and air pollution caused by the traditional painting process, a new electrostatic spraying process is adopted. A large part of the components of the car, such as the car body, bumper, interior and exterior trim, etc., are all plastic products, which cannot form an electric field. In order to realize the electrostatic spraying process, it is necessary to first coat a layer of conductive primer on the surface of the workpiece, and then carry out electrostatic spraying. At present, the conductive primer for automobile spraying is mainly made conductive by adding a large amount of conductive carbon black, which causes the pig...
