Title:
HIGH DURABILITY THERMALLY CONDUCTIVE COMPOSITE AND LOW PUMP-OUT GREASE
Document Type and Number:
WIPO Patent Application WO/2012/067247
Kind Code:
A1
Abstract:
Provided is a high durability thermally conductive composite containing 0.5-10 volume% of a high molecular weight silicone with vinyl groups on both ends with viscosity at 25°C of 10000-15000 Pa-s, 1-10 volume% of an alkylalkoxysilane, and 40-65 volume% of an inorganic filler with the remainder being an addition-reacting low molecular weight silicone with viscosity at 25°C of 0.2-0.5 Pa-s. Also provided is a grease characterized in containing 38-48 volume% of an addition-reacting low molecular weight silicone with viscosity at 25°C of 0.2-0.5 Pa-s, 2-8 volume% of a high molecular weight silicone with vinyl groups on both ends with viscosity at 25°C of 10000-15000 Pa-s, and 50-60 volume% of an inorganic filler. It is preferable that the alkylalkoxysilane is a triethoxysilane or trimethoxysilane wherein the number of carbons in the alkyl groups is six to ten.
