The invention discloses a graphene composite material with high electrical conductivity. The graphene composite material is prepared from the following components: graphene, carbon nanotubes, conductive carbon black, epoxy resin, hydroxy acrylic resin, a curing agent, aniline, nano silicon powder, FeSO4.7H2O, FeCl3.6H2O, an ethylene-vinyl acetate copolymer, white oil, zirconium hydrogen phosphate,butyl acrylate emulsion, N-methylpyrrolidone, polytetrafluoroethylene, polyvinylidene chloride emulsion, sodium dodecyl sulfonate and additives. The graphene composite material with high electrical conductivity is prepared from a series of materials which have compatibility with the graphene and can improve the electrical conductivity of the graphene composite material, so that the problem that the traditional graphene composite material is low in electrical conductivity is solved.
