Abstract

The invention belongs to the technical field of nanomaterial processing and non-metal surface electroplating, and in particular relates to a nano-conductive carbon paste for surface electroplating of non-metal insulating materials and a preparation method thereof, comprising conductive carbon black, nonylphenol polyoxyethylene ether, polyvinylpyrrolidone , Styrene acrylate emulsion, tetraethyl orthosilicate and water. Coating the conductive carbon paste prepared by the present invention on the surface of non-metal substrate can save the process of sensitization, activation and electroless metal plating, without using formaldehyde as reducing agent, without using expensive metals such as palladium and silver, which greatly simplifies The electroplating process reduces the cost of electroplating and reduces the pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of nano material processing and non-metal surface electroplating, and in particular relates to a nano-conductive carbon paste for non-metal insulating material surface electroplating and a preparation method thereof. Background technique [0002] Before electroplating non-metallic materials such as plastics, ceramics, glass, gypsum, wood, etc., surface treatment is required to make the plated parts have a good surface state and electrical conductivity. Traditional non-metallic electroplating uses chemical electroplating. The process includes: (1) Mechanical roughening, generally using sandblasting to increase the contact area between the coating and the substrate and improve the bonding strength; (2) Chemical degreasing; (3) Chemical roughening to further improve the effect of mechanical roughening; (4) ) sensitization and activation, sensitization makes the non-metal surface adsorb a layer of easily oxidiza...
