Abstract

PURPOSE: Titled composition having excellent lubricating properties and oil resistance, prepared by vulcanizing and molding a composition prepared by mixing a nitrile rubber polymer, carbon black, fine powder of a parallel cleaving mineral and fine powder of cellulose, and then impregnating the molded product with aliphatic and aromatic lubricating oil.
CONSTITUTION: A nitrile rubber composition is obtained by mixing (A) 100pts.wt. of a nitrile rubber polymer with (B) 30W50pts.wt. of carbon black, (C) 30W 50pts.wt. of fine powder of a parallel cleaving mineral and (D) 5W30pts.wt. of cellulose fine powder. Then, this composition is vulcanized, molded and immersed in aliphatic and aromatic lubricating oil heated to 100W150°C to impregnate the fine cellulose powder with the lubricating oil. Thereby, it is made possible to give satis factory lubricity to the lip part without impairing the sealability of sealing fluid.
