NOVELTY - High thermal conductive composite material comprises copper foil that is used as a substrate, and graphene acrylic resin composite material that is bonded to the surface of the copper foil, where the graphene acrylic resin composite material comprises an acrylic resin material and graphene, and is prepared by subjecting graphene and acrylic resin to ball-milling and pre-heat treatment to obtain the product. USE - High thermal conductive composite material used in radiating field. ADVANTAGE - The high thermal conductive composite material has good contact between the layers of graphene sheets, enables to realize the smooth conduction of the graphene heat conduction channel, and realize the integration of the structure and function of the material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing high thermal conductive composite material, which involves involves subjecting graphene and acrylic resin to ball-milling and pre-heat treatment to obtain a graphene acrylic resin composite material, raising the temperature to a certain temperature, coating the acrylic resin composite material uniformly on the surface of the copper foil, performing continuous rolling until the thickness of the graphene acrylic resin composite material layer is between 2-100 mu m and cooling to obtain high thermal conductive composite material.
