Method for electrodeposition painting of CFRP and paint-electrodeposited CFRP therefrom

摘要

The present invention relates to an electrodeposition coating method of carbon fiber reinforced plastic and an electrodeposited carbon fiber reinforced plastic. The electrodeposition coating method of carbon fiber reinforced plastic according to the present invention comprises: a step of increasing surface roughness through surface-treating the surface of the carbon fiber reinforced plastic; an activation step of forming a palladium layer on the surface of the carbon fiber reinforced plastic with increased surface roughness; a step of giving conductivity to the carbon fiber reinforced plastic through chemically plating nickel after the activation; a step of electroplating the nickel after the nickel chemical plating; and a step of forming an electrodeposition coating layer through electrodepositing electrodeposition paint after the nickel electroplating.
