Patent ID: 7601773

Claim:
A room temperature-curable, heat-conductive silicone rubber composition, comprising: (A) 100 parts by mass of an organopolysiloxane represented by a general formula (1) shown below: wherein, each R 1 represents, independently, a hydrogen atom, or an unsubstituted or substituted monovalent hydrocarbon group, R 2 represents identical or different, unsubstituted or substituted monovalent hydrocarbon groups, each Z represents, independently, an oxygen atom or a bivalent hydrocarbon group, a represents 0, 1 or 2, and n represents an integer of 10 or greater, (B) 10 to 4,000 parts by mass of aluminum powder, (C) 1 to 50 parts by mass of an organosilicon compound represented by a general formula (2) shown below: R 3 b SiX 4-b (2) (wherein, R 3 represents an unsubstituted or substituted monovalent hydrocarbon group, X represents identical or different hydrolyzable groups, b represents 0, 1 or 2, and when b=2, the R 3 groups may be identical or different, and/or a partial hydrolysis-condensation product thereof, and (D) 0.01 to 1.0 parts by mass of a palladium powder per 100 parts by mass of the aluminum powder.
