Abstract

The invention relates to a resin formed composite material, and in particular relates to a heat-conducting water-proof gasket. The heat-conducting water-proof gasket is prepared by the following steps: initially mixing, namely adding 8-12 parts by weight of heat-conducting material into 40-100 parts by weight of matrix resin to obtain an initial mixture; plasticizing and granulating, namely adding 2-8 parts by weight of flame retardant, 6-10 parts by weight of softening and plasticizing agent, 3-7 parts by weight of toughening agent, 1-4 parts by weight of coupling agent and 0.6-1.2 parts by weight of antioxidant into the initial mixture, coblending, modifying, plasticizing, extruding and granulating to obtain first particles; remixing and foaming, namely mixing 15-25 parts by weight of either or both of fatty alcohol-polyoxyethylene ether sodium sulfate or an azoic compound with either or both of the first particles and 30-70 parts by weight of matrix resin, extruding and foaming to obtain a foamed material, compounding a fully-perforated foamed material layer and a moisture-proof film layer on the foamed material in sequence by using glue to form the heat-conducting water-proof gasket. The heat-conducting water-proof gasket is high in heat-conducting efficiency and resistant to water, and has a damping function.
