NOVELTY - The utility model claims a plating structure for sealing red copper and nano graphene, comprising a metal substrate, and a cyanide pre-plating copper layer, a middle copper plating layer, a bright copper plating layer, a gun black tin nickel alloy plating layer and a graphene sealing layer from inside to outside in turn on the metal substrate. The red copper plating layer structure of the utility model uses the aqueous graphene sealing agent to replace the traditional solvent type transparent paint, has no pollution to the production environment, and has good corrosion resistance. according to GB/T 10125-2012 artificial atmosphere corrosion test salt mist test for neutral salt fog test for 48 h, the plating surface without corrosion, the corrosion resistance is higher than the traditional solvent transparent paint sealed red copper plating.
