Abstract

A method for preparing a silicone rubber from a silicone rubber compound, characterized in comprising (A) 100 parts by weight of an organopolysiloxane of the following general compositional formula (1) (1) in which R1 is a substituted or unsubstituted monovalent hydrocarbon group, 0.001 to 0.5 mol% of R1 being an alkenyl group, and letter a is a positive number of 1.95 to 2.05, the organopolysiloxane having an average degree of polymerization of at least 100, (B) 5 to 200 parts by weight of a reinforcing silica filler having a specific surface area of 50~800 m2/g as measured by a BET method, and (C) 0.1 to 10 parts by weight of an organohydrogenpolysiloxane of the following general compositional formula (2): (2) in which R2 is a substituted or unsubstituted monovalent hydrocarbon group, and letters b and c are positive numbers satisfying 1≰b≰2, 0.1≰c≰1.2, and 1.8≰b+c≰2.2, the method comprising the steps of: mixing component (C) with components (A) and (B) and heating them at a temperature of 100℃~300℃ to form the silicone rubber compound, adding an organic peroxide or a platinum group metal catalyst to the compound, and crosslinking the compound.
