High-performance heat dissipation composite material

The invention discloses a high-performance heat dissipation composite material which is prepared from the following components in parts by weight: 1 part of silicone rubber, 20-60 parts of white carbon black, 1-2 parts of aluminum oxide, 1-2 parts of silicone oil, 2-60 parts of synthetic resin, 3-50 parts of conductive carbon black, 3-60 parts of silver powder, 3-50 parts of aluminite powder, 3-40 parts of quartz powder, 3-30 parts of silica powder, 3-30 parts of antimonous oxide and 1-6 parts of a pigment, wherein the raw materials are mixed by adopting a kneading machine and then molded by adopting a rubber injection molding machine. By adopting the high-performance heat dissipation composite material with the components, the heat dissipation effect of an electronic product is improved, the ratios of the silicone rubber, the white carbon black, the aluminum oxide and the silicone oil are adjusted according to the requirements of the volume of a radiator, the ratio of the synthetic resin is adjusted accordin
