Abstract

PURPOSE: To prepare a rubber composition having excellent kneadability, and giving a vulcanized rubber having high heat resistance, low-tepmerature resistance, and oil resistance, by compounding a silicone green rubber and an acrylic green rubber with a third component comprising an organosiloxane-acrylic ester copolymer.
CONSTITUTION: A composition composed of (A) 100 parts by weight of a rubber mixture containing (a) 10W90 parts of a polysiloxane of the formula (R is monofunctional hydrocarbon, provided that 0.02W10 mol% of R is vinyl; a is 1.90W 2.05), having a polymerization degree of ≥2000, and (b) 90W10 parts of an acrylic green rubber having a Mooney viscosity of 10W80 (ML1+4, 100°C),(B) 5W50 parts of an organosiloxane-acrylic ester copolymer containing 20W80 wt% of acrylic ester component, and (C) 0.1W15 parts of an organic peroxide.
EFFECT: Free from separation of each component after kneading, easily curable only by the use of the organic peroxide, and having advantages of both components.
