| 中文摘要: |
| 研究混炼工艺对丁腈橡胶（NBR）硫化特性和力学性能的影响。结果表明：混炼工艺对NBR胶料和制品的性能稳定性影响较大，密炼机混炼排胶后在开炼机上加入硫化体系的工艺的可控性较好，胶料性能更稳定；返炼可以适当改善胶料的加工性能和力学性能，但不能完全解决混炼不均的问题。 |
| 英文摘要: |
| The effect of mixing process on the vulcanization characteristics and mechanical properties of nitrile rubber（NBR） was studied. The result showed that the mixing process had great influence on the properties stability of NBR compounds and products，and the process of adding curing system on open mill after mixing in internal mixer had better controllability and more stable properties of compounds.The processability and mechanical properties of compounds could be improved by remixing，but the problem of uneven mixing could not be solved completely. |
