LIQUID SILICONE RUBBER COMPOSITION FOR FIXING ROLL AND FIXING ROLL COATED WITH FLUORORESIN

摘要

PROBLEM TO BE SOLVED: To provide a liquid silicone rubber composition for fixation which hardly deteriorates hardness even when subjected to high temperature treatment and can be made silicone rubber which is excellent in durability and hardness stability and to provide a fixing roll coated with fluororesin which is excellent in hardness stability and reliability. SOLUTION: This liquid silicone rubber composition for fixing roll comprises diorganopolysiloxane (A) which has at least two Si-combined alkenyl groups in one molecule and is liquid at an ordinary temperature, inorganic filler (B), organohydrodiene polysiloxane which has at least two Si-combined hydrogen atoms in one molecule (C), platinum based catalyst (D) and powdery alkaline metal hydroxide or oxide, or powdery alkaline earth metal hydroxide or oxide (E). Also, this fixing roll coated with fluororesin is constituted by forming a fluororesin layer on the outer peripheral surface of the roll shaft via a silicone rubber layer which is a cured body of the said liquid silicone rubber composition.
