▎ 摘　　要

NOVELTY - A silicon dioxide/graphene/graphite composite heat-conducting silicone grease comprises 20-40 parts mass silicone oil, modified silicon dioxide/graphene/graphite compound thermal conductive filler, 3-8% thermal conductive filler coupling agent, 0.1-1% crosslinking agent comprising dimethicone, 0.1-1 part mass surface modifier and 0.1-1 part mass antioxidant. USE - Silicon dioxide/graphene/graphite composite heat-conducting silicone grease (claimed). ADVANTAGE - The silicon dioxide/graphene/graphite composite heat-conducting silicone grease: can effectively lower interface contact heat resistance between high-power electrical appliance node and cooling device; can accelerate heat transfer; and can be prepared in a simple and economical manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of silicon dioxide/graphene/graphite composite heat-conducting silicone grease.
