The invention discloses a graphene plastic color masterbatch. The graphene plastic color masterbatch is prepared from the following raw materials in parts by weight: 15 to 25 parts of carrier resin, 25 to 35 parts of conductive carbon black, 30 to 40 parts of nano-graphene sheets, 5 to 10 parts of chlorinated paraffin, 1 to 3 parts of butyl stearate, 0.1 to 0.5 part of N-(beta-aminoethyl)-gamma-amino propyl trimethoxy silane, 0.01 to 0.1 part of 2,6-butylated hydroxytoluene, 0.1 to 0.5 part of an ultraviolet light absorbent and 0.1 to 1 part of an anti-oxygen synergist. According to the graphene plastic color masterbatch provided by the invention, the construction process is simple and stable and the added graphene sheets improve the interface strength, so that the graphene plastic color masterbatch has excellent mechanical property, ageing resistance, acid and alkali resistance and long service life.
