熱伝導性複合シリコーンゴムシート

Japanese Patent JP7149229

B2

The present invention is a thermal conductive composite silicone rubber sheet including a thermal conductive silicone rubber sheet and a thermosoftening silicone resin layer provided with a thickness of 0.5 to 10 µm on at least one side of the thermal conductive silicone rubber sheet, the thermosoftening silicone resin layer having an absolute viscosity at 70°C of 700 Pa·s or lower, where the thermosoftening silicone resin layer has adhesion of 0.5 N/25 mm or higher at a normal temperature and the thermal conductive composite silicone rubber sheet has a thermal resistance that is lower than a value obtained by adding 0.3 cm²·K/W per one layer of one side of the thermosoftening silicone resin layer to a thermal resistance of the thermal conductive silicone rubber sheet. This provides a thermal conductive composite silicone rubber sheet provided with an adhesive layer on at least one side of a thermal conductive silicone rubber sheet, that makes it possible to impart adhesion without sacrificing thermal conductivity as much as possible.
