The invention relates to a graphite composite gasket. The graphite composite gasket comprises an artificial graphite flake, wherein one side of the surface of the artificial graphite flake is coated with a heat conducting layer, the heat conducting layer is formed by the following components in percentage by weight: 5%-15% of siloxane group resin, 80%-90% of heat conducting filler and 1%-10% of addition agent and is formed by a production method in a surface modification treatment technology. The graphite composite gasket disclosed by the invention has the advantages that since the artificial graphite flake has 1500W/mK-2500W/mK of high heat conducting coefficient in the horizontal direction, and heat can be rapidly and uniformly dispersed to a cooling platform; due to the excellent elasticity characteristic of the heat conducting layer, air between devices can be squeezed out to a larger extent, holes can be filled, and thus the accumulation of the heat can be reduced; the advantages of the artificial graphite flake and the heat conducting layer can be integrated, the heat is prevented from being accumulated on the surface of the graphite composite gasket, the devices are prevented from being used under high temperature, the damage to the devices is reduced, the service life of the devices is prolonged, heat conducting layers of different devices can subject to selective processing according to heating situations of different devices, the practical performance is increased, and the using effect is good.
