NOVELTY - Electroplating plastic surface comprises (i) mixing graphene, silicon dioxide sol, epoxy resin, curing agent and water, adjusting the pH value to 5-6, obtaining the mixed slurry, (ii) removing oil, first water washing, firstly drying, spraying the mixed slurry to the surface of the first dried plating piece, drying for the second time, then carrying out chemical plating and electroplating, second water washing, and drying to obtain the plastic after plating. USE - The plastic surface is useful for door guard plate of automobile. ADVANTAGE - The plastic surface: improves the bonding strength of the metal plating layer and the door guard plate of the plastic material, and prolongs the service life of the plate; simplifies the plating process and improves the characteristics-friendly performance of plating.
