Liquid form addition curing type silicone rubber composition for fluororesin covered fixing roller and fluororesin covered fixing roller |
摘要 |
A liquid form addition curable silicone rubber composition for forming a fluororesin covered fixing roller is provided. This composition includes (a) 100 parts by weight of an organopolysiloxane with at least two alkenyl groups bonded to non-terminal silicon atoms; (b) an organohydrogenpolysiloxane with at least two silicon-bonded hydrogen atoms, in a sufficient quantity to produce a molar ratio of silicon-bonded hydrogen atoms within said constituent (b) relative to silicon-bonded alkenyl groups within said constituent (a) of 0.4 to 5.0; (c) an effective quantity of a platinum based catalyst; (d) 0.1 to 10 parts by weight of dry process silica; and (e) 0.05 to 5 parts by weight of a cyclic diorganopolysiloxane with at least three silicon-bonded alkenyl groups. This composition is used for formation of the silicone rubber layer of a fixing roller made up of a metal core, a silicone rubber layer on the core, and a fluorine based coating provided on the rubber layer. Good adhesion is obtained between the silicone rubber layer and both of the metal core and the fluorine-based coating, and as a result excellent durability is achieved.
