NOVELTY - An ultra-high-speed dry-grinding fluororubber oil seal material comprises 100 pts. wt. modified fluororubber raw rubber, 0-40 pts. wt. modified crystal whisker, 0-20 pts. wt. fiber, 0-10 pts. wt. graphite, 0-10 pts. wt. PTFE micropowder, 0-5 pts. wt. graphene, 0-15 pts. wt. acid acceptor and 0-3 pts. wt. release agent. USE - Ultra-high-speed dry-grinding fluororubber oil seal material. ADVANTAGE - Ultra-high-speed dry-grinding fluororubber oil seal material has improved high and low temperature resistance, finish degree of the surface, rebound resilience and mechanical property and reduced friction coefficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of ultra-high-speed dry-grinding resistant fluororubber oil seal material, which involves blending all the raw materials in the internal mixer for banburying, molding, adding the ultra-high-speed dry-resistant fluororubber into the extruder, extruding and forming.
