High-strength heat-conducting silica gel material and preparation method thereof

The invention relates to the technical field of heat-conducting silica gel, and particularly relates to a high-strength heat-conducting silica gel material and a preparation method thereof. The high-strength heat-conducting silica gel material is prepared from 46 to 60 parts by weight of graphene oxide, 30 to 38 parts by weight of polydimethylsiloxane, 8 to 15 parts by weight of dimethylformamide, 6 to 10 parts by weight of dicyclohexylmethane diisocyanate, 5 to 12 parts by weight of absolute ethyl alcohol and 4 to 8 parts by weight of dihydroxy polydimethylsiloxane. The graphene oxide filler added in the invention has a reinforcing effect on the silicone rubber, and the composite coating makes the heat-conducting silica gel material have certain elasticity and viscosity, so the whole system has a certain buffer effect, the contact thermal resistance between the heat-conducting silica gel material and a battery is reduced, the heat dissipation performance of the whole system is further improved; the cellulose
