Production method for graphene-metal material

The invention relates to a production method for a graphene-metal material. The production method comprises the following steps: (1) coating the surfaces of metal wires with certain wire diameters with a graphene slurry by virtue of a multilayer continuous coating process, and carrying out drying and shaping to obtain a film; (2) combining a plurality of the graphene-coated wires and then enablingthe graphene-coated wires to continuously pass through a wire compounding winding system composed of one or more wire compounding dies, and carrying out one-time wire compounding or multi-time wire compounding to prepare a graphene-alloy compound wire with the needed wire diameter or wire number; and (3) carrying out extrusion forming on one or more graphene-alloy compound wires through a continuous wire compounding extruder to prepare a wire rod with a certain length and certain section shape dimensions or a granular graphene-alloy intermediate. The graphene-metal material produced through the abovementioned process
