摘　　要：研究生胶体系、防护体系、增塑体系、硫化体系对丁腈橡胶(NBR)硫化胶性能的影响。结果表明:当单独采用丙烯腈含量为29%的NBR2707或NBR N640时,NBR硫化胶的耐油性能优异,但耐低温性能较差;适宜的防护体系可以在不影响NBR硫化胶的力学性能的前提下,提高其耐油性能和抗压缩永久变形性能;采用增塑剂DOS/TP-95体系的NBR硫化胶的力学性能和耐油性能优于单独采用增塑剂DOS或TP-95的NBR硫化胶;采用过氧化物DCP/甲基丙烯酸镁和过氧化物BIPB/硫黄给予体硫化体系的NBR硫化胶的综合性能优异。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.
