Silicone rubber composition having flame-retardant and electrical insulating properties

摘要

A silicone rubber composition is disclosed that cures into a highly flame-retardant silicone rubber with excellent electrical insulation characteristics and that does so without sacrificing mechanical strength. Said silicone rubber composition comprises:(A) polyorganosiloxane described by average formula R_aSiO_(4-a)/, where R denotes substituted and unsubstituted monovalent hydrocarbon groups and a is a number from 1.95 to 2.05 and having at least 2 silicon-bonded alkenyl groups in each molecule;(B) silica filler;(C) the reaction mixture of(a) a platinum compoundand(b) a compound containing a carbon-carbon double bond and a carbon-carbon triple bond;(D) curing agent,and optionally(E) a triazole compound.
