▎ 摘　　要

NOVELTY - Thermally conductive silicone rubber composite material comprises methylphenyl vinyl silicone rubber, modified graphene oxide having amount 0.1-0.8% of the weight of the thermally conductive silicone rubber composite material, boron nitride having amount 1-3% of the weight of the thermally conductive silicone rubber composite material, and aluminum oxide having amount 0.5-2% of the weight of the thermally conductive silicon rubber composite material. The modified graphene oxide is prepared by dispersing graphene oxide in tetrahydrofuran uniformly, adding vinyltrimethoxysilane to the dispersion, irradiating under ultraviolet light of 280-190 nm, washing product with tetrahydrofuran to remove homopolymer of polysiloxane and unreacted vinyltrimethoxysilane to obtain modified graphene oxide. USE - Used as thermally conductive silicone rubber composite material. ADVANTAGE - The thermally conductive silicone rubber composite material has good thermal conductivity, and mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing thermally conductive silicone rubber composite material comprising (1) uniformly dispersing graphene oxide in tetrahydrofuran, adding vinyltrimethoxysilane to the dispersion, irradiating under ultraviolet light of 280-190 nm for 30-60 minutes, washing product with tetrahydrofuran to remove homopolymer of polysiloxane and unreacted vinyltrimethoxysilane to obtain modified graphene oxide, and drying at below 30 degrees C, (2) adding methylphenyl vinyl silicone rubber in mixer, (3) adding modified graphene oxide, boron nitride, and aluminum oxide to the uniformly mixed methylphenyl vinyl silicone rubber and mixing uniformly in the mixer, and (4) vulcanizing obtained rubber in a flat-plate vulcanizer at 160-180 degrees C at 12-16 MPa.
