Heat-conducting gasket and preparation method thereof

The invention discloses a heat-conducting gasket and a preparation method thereof. The heat-conducting gasket is prepared from the following components in parts by weight: 600-2700 parts of heat-conducting powder; 3-50 parts of vinyl silicone oil; 0.01 to 10 parts of a cross-linking agent; 0.1 to 20 parts of a chain extender; 0.01 to 3 parts of an inhibitor; 0.01 to 3 parts of a catalyst; 0.1 to 1 part of a silane coupling agent; wherein the heat conduction powder is prepared from 400 to 1800 parts of aluminum nitride; the cross-linking agent is side chain hydrogen-containing silicone oil, and the hydrogen content of the side chain hydrogen-containing silicone oil is 0.05%-0.75%; the chain extender is end hydrogen-containing silicone oil, and the hydrogen content of the end hydrogen-containing silicone oil is 0.01%-0.75%. The heat-conducting gasket prepared according to the proportion has the advantages of low volatilization, high compression and high heat conductivity. 本申请公开了一种导热垫片及其制备方法。以重量份计，导热垫片由以下组分制备而成：
