NOVELTY - Graphene-metal composite material comprises metal powder, graphene powder and adhesive. The metal powder comprises multiple metal particles. The adhesive comprises wax material. The graphene powder comprises multiple graphene micro sheet with graphene molecules containing 6 carbon atoms that are annularly connected. The graphene molecule of carbon atom is triple covalent bond that is connected to functional radical. The production of graphene-metal composite material involves mixing metal powder, graphite powder and adhesive to obtain powder raw material, mixing under friction heat to every functional group to connect each triple covalent bond, breaking absorbing heat, and cleaving each of graphene molecule bond by triple covalent bonds to obtain graphene molecules that covers metal particles; and sintering dewaxed product to form metal particles fusion, and mixing with metal main body and graphene molecules to form three-dimensional net shape combined metal main body.

The metal powder comprises multiple metal particles. The adhesive comprises wax material. The graphene powder comprises multiple graphene micro sheet with graphene molecules containing 6 carbon atoms that are annularly connected. The graphene molecule of carbon atom is triple covalent bond that is connected to functional radical. The production of graphene-metal composite material comprises mixing metal powder, graphite powder and adhesive to obtain powder raw material, mixing under friction heat to every functional group to connect each triple covalent bond, breaking absorbing heat, subjecting functional group from graphene into molecular separation, and cleaving each of graphene molecule bond by triple covalent bonds to obtain graphene molecules that covers metal particles; heating raw material powder to melt into liquid state mixed raw material, mixing with metal powder, adhesive and graphene powder liquid, mixing liquid raw material into mold, placing into injection molding and curing to obtain blank; removing adhesive in the blank to obtain de-waxed product, subjecting into solvent dewaxing to remove adhesive portion of blank and hot dewaxing at 140-170 degrees C to form dewaxed product into gap; and sintering dewaxed product to form metal particles fusion, and mixing with metal main body and graphene molecules to form three-dimensional net shape combined metal main body.
