Abstract:
1. A method for producing a silicone rubber compound comprising the steps of mixing the components (A) to (C): (A) 100 parts by weight of an organopolysiloxane having a degree of polymerization of at least 100 represented by the following average compositional formula (I): wherein R 1 is independently a substituted or unsubstituted monovalent hydrocarbon group, and a is a positive number of 1.95 to 2.05, (B) 5 to 100 parts by weight of a reinforcing silica having a specific surface area as measured by BET absorption method of at least 50 m (C) a preliminary hydrolysis product of wherein R 2 is independently hydrogen atom or a substituted or unsubstituted monovalent hydrocarbon group, R 3 is independently a substituted or unsubstituted alkyl group, and m is 0, 1, 2, or 3, and subjecting the mixture to a heat treatment.
