The invention discloses high-heat-conductivity ternary rubber. An anti-aging agent is one type or more types of the following reagents: N-phenyl-alpha-aniline, N-phenyl-beta-naphthylamine, N-phenyl-N'-cyclohexyl p-phenylenediamine, N-phenyl-N'-isopropyl-p-phenylenediamine and N-N'-diphenyl-p-phenylenediamine. An accelerant is one type or more types of the following reagents: an accelerant T, N,N-tetramethyl dithio-dithiocarbonyl amine, tetramethylthiuram disulfide, thiram, a vulcanization accelerant TMTD and tetramethylthiuram disulfide. By adoption of mixed fillers, the heat conductivity of the composite material is greatly improved. Granules and crystal whiskers with a certain length-diameter ratio form continuous heat-conducting network chain; combination of fillers with different grain size is selected, so high filling density is achieved; and the interface of the fillers and a matrix is improved by a coupling agent, so the heat resistance at the interface is reduced.
