Abstract
The invention relates to a rubber member, and particularly relates to a filter rubber member capable of resisting a low temperature of -43 DEG C. The filter rubber member is composed of N230S acrylonitrile, N250S acrylonitrile, a vulcanizing agent, high abrasion-resistant carbon black, a plasticizer, zinc oxide, stearic acid and a processing aid. The filter rubber member has the beneficial effects that (1) by controlling the content of acrylonitrile reasonably and co-using N230S acrylonitrile and N250S acrylonitrile, low temperature-resistant performance, high temperature-resistant performance and oil resistance are increased significantly; (2) a peroxide curing system is employed in the vulcanization system, so that tensile strength of the rubber is high, rebound resilience is excellent and high and low temperature resistance are excellent; (3) the high abrasion-resistant carbon black and spray carbon black are co-used in a rubber reinforcing system, so that physical and mechanical properties of the rubber are excellent and compression permanent deformation is small; and (4) amine and heterocyclic anti-ageing agents are co-used in an anti-ageing system, so that the oil resistance is excellent.
