▎ 摘　　要

NOVELTY - Low-pressure and high-temperature resistant silicone rubber comprises 100 pts. wt. silicone rubber, 0.5-5 pts. wt. vulcanizing agent, 0-5 pts. wt. cross-linking agent, 5-50 pts. wt. white carbon black, and 0.1-5 pts. wt. nano-filler modified with fluorine-containing silane coupling agent. USE - The silicone rubber is useful as sealing material for high temperature working conditions. ADVANTAGE - The silicone rubber has high mechanical strength, and good elasticity. The method improves the dispersibility of nano-filler and high temperature thermal stability of silicone rubber. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the silicone rubber, comprising uniformly mixing the raw materials, placing the uniformly mixed material at room temperature for more than 16 hours, re-refining, pressing and molding by hot molding, and curing after high temperature heat treatment.
