COMPOSITE MATERIAL OF RUBBER COMPOSITION WITH FIBER AND HOSE

摘要

PURPOSE:To obtain the title composite material having high oil resistance and high heat resistance by bonding a highly hydrogenated acrylonitrile copolymer rubber composition with a specified organic fiber material. CONSTITUTION:The title composite material is obtained by bonding a rubber composition (A) comprising 100 pts.wt. copolymer rubber having 10-45wt.% unsaturated nitrile units, 0-5wt.% conjugated diene units and 90-50wt.% units formed by hydrogenating units derived from an ethylenically unsaturated monomer other than the unsaturated nitrile and/or units derived from a conjugated diene in the polymer chain, 0.2-15 pts.wt. organic peroxide vulcanizer (in terms of the net peroxide) and 1-20 pts.wt. MgO with an organic fiber material (B) treated with a mixture containing 30-70 pts.wt. resorcinol/formalin precondensate of a resorcinol to formalin feed molar ratio of 5:3-1:1. In this way, the title composite material of a rubber composition with a fiber, having high oil resistance and high heat resistance can be obtained.
