description The invention relates to paste heat-conductive silicone grease and a preparation method of the paste heat-conductive silicone grease. The paste heat-conductive silicone grease comprises, by weight, 100 parts of methyl silicone oil, 400-1000 parts of heat-conductive padding, and 40-200 parts of coupling agents. Surface modification is carried out on the heat-conductive padding by selecting a proper amount of the coupling agents, compatibility of the heat-conductive padding and the methyl silicone oil is strengthened, the dispersing performance of the heat-conductive padding in the methyl silicone oil is improved, the heat-conductive performance of the heat-conductive silicone grease is largely improved, the coefficient of heat conductivity can reach 3.0 W/m.k, even 4.0 W/m.k, and the heat-conductive silicone grease has little leaked oil, good heat-resistant performance, and good anti-slipping performance, thereby being quite suitable for serving as heat-dissipation materials of electric elements and electronic
