Abstract

The invention relates to a resin foam material, and particularly relates to a high thermal conductivity foam material. The high thermal conductivity foam material is prepared by adopting the following steps: uniformly mixing 8-12 parts of heat conduction material and 40-100 parts of one or more of low density polyethylene, high density polyethylene, linear low density polyethylene or ethylene-vinyl acetate copolymer by weight so as to obtain a primary mixture; plasticizing and pelleting, to be specific, adding 2-8 parts of flame retardant, 6-10 parts of softening plasticizer, 3-7 parts of toughening agent, 1-4 parts of coupling agent and 0.6-1.2 parts of antioxidant by weight to the primary mixture, carrying out blending modification, plasticizing, and extruding and pelleting so as to obtain first particles; blending again and foaming, to be specific, mixing 15-25 parts of one or more of fatty alcohol polyoxyethylene ether sodium sulphate or azo-compounds, the first particles and 30-70 parts of one or more of low density polyethylene, high density polyethylene, linear low density polyethylene or the ethylene-vinyl acetate copolymer by weight, and extruding and foaming. The prepared high thermal conductivity foam material has high thermal conductivity and is waterproof and shock-proof.
