Abstract:
      The effect of raw rubber system，anti-aging system，plasticizing system and vulcanization system on the properties of nitrile butadiene rubber （NBR） vulcanizates was studied.The results showed that when NBR2707 or NBR N640 with 29% acrylonitrile content was used alone，NBR vulcanizate had excellent oil resistance，but poor low temperature resistance.A suitable anti-aging system could improve the oil resistance and compression set resistance of NBR vulcanizate without affecting the mechanical properties.The mechanical properties and oil resistance of NBR vulcanizate using plasticizer DOS/TP-95 system were better than those of the NBR vulcanizate using the plasticizer DOS or TP-95 alone.The comprehensive properties of NBR vulcanizates using peroxide DCP/magnesium methacrylate and peroxide BIPB/sulfur donor vulcanization systems were excellent.
