| 中文摘要: |
| 以胺类和酚类防老剂为主防老剂、以亚磷酸酯类和硫酯类防老剂为辅助防老剂、以复配环保单剂的形式制备复合环保防老剂，并研究其在丁腈橡胶（NBR）中的应用。结果表明：复合环保防老剂可以加快NBR的硫化速度，提高交联密度和物理性能；当主防老剂4010NA质量分数为0.25～0.30、主防老剂Anox 1315质量分数为0.20～0.25、辅助防老剂Weston 705质量分数为0.15～0.20、辅助防老剂1520质量分数为0.10～0.15、溶剂为环烷油时，复合环保防老剂对NBR防护效果最佳，可以满足NBR在高温下的耐油性能要求。 |
| 英文摘要: |
| The environmentally friendly compound antioxidant was prepared by using amine and phenolic antioxidant as the main antioxidants，phosphite ester and sulfur ester antioxidant as the auxiliary antioxidants，which were all environmentally friendly components. The application of the environmentally friendly compound antioxidant in NBR compound was investigated. The results showed that，with the addition of the compound antioxidant，the curing rate of NBR compound increased，the crosslink density increased and the physical properties were improved. It was found that the compound antioxidant with following formulation provided NBR compound the best anti-aging effect：antioxidant 4010NA 0.25～0.30 （mass fraction），Anox 1315 0.20～0.25，auxiliary antioxidant Weston 705 0.15～0.20，antioxidant 1520 0.10～0.15，and naphthenic oil as the solvent. The NBR compound with this compound antioxidant could meet the requirements of oil resistance at high temperature. |
