| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
