▎ 摘　　要

NOVELTY - Silicone insulating gasket includes a thermally conductive silica gel base layer (1) and a graphene dispersion liquid (2), and the top surface and the bottom surface of the thermally conductive silica gel base layer are respectively coated with graphene dispersion liquid. The thermally conductive silica gel base layer includes a silicone gel and a modified filler. The modified filler includes a thermally conductive filler, a reinforced thermally conductive filler, anhydrous ethanol, silane, and polysiloxane. The graphene dispersion liquid includes a silicone rubber matrix and modified graphene powder. USE - Silicone insulating gasket. ADVANTAGE - The silicone insulating gasket uses graphene dispersion coated on the heat conducting silica gel layer, using the graphene super hardness andspecific physical properties, makes up the traditional heat conducting silica gel matrix toughness difference, increases the bending strength of the system, at the same time, combining graphene of ultra-high heat conductivity and excellent heat radiation ability, resulting in system heat conducting and heat dissipation ability, in the traditional heat conducting silica gel system has one more channel heat radiation capability, and both are combined, so that more heat be radiated out. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a silicone insulating gasket, which involves brush-coating graphene dispersion liquid on the top surface of the thermal conductive silica gel base layer, and after being completely cured, continuously brush-coating the graphene dispersion liquid on the bottom surface of the thermal conductive silica gel base layer. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of silicone insulating gasket. Thermally conductive silica gel base layer (1) Graphene dispersion liquid (2)
