▎ 摘　　要

NOVELTY - Heat-conducting and caulking material comprises 14-20 wt.% silicon rubber, 20-40 wt.% graphene/carbon nano tube composite material, 30-60 wt.% metal oxide, 0.1-1 wt.% coupling agent and 1-2 wt.% liquid metal. USE - The material is useful for radiating electronic component (claimed). ADVANTAGE - The material has good synergistic effect, isotropic thermal conductivity, better isotropic conductivity and three-dimensional space network of micropores. The method solves the problem that the traditional graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing material, comprising (i) taking the raw material, (ii) adding the solid particles in the raw material into a ball mill, stirring and grinding for 20-30 minutes to obtain a solid mixture, (iii) placing solid mixture with the liquid material in the raw material into a stirrer, stirring uniformly, rolling process, and baking through high temperature, the baking time is 25 minutes and baking temperature is 120 degrees C.
