| 中文摘要: |
| 用热空气老化和热分析的方法，考察了复合型防老剂8PPD对天然橡胶(NR)、顺丁橡胶(BR)和丁苯橡胶(SBR)的热氧老化防护性能，并与防老剂D，RD，40l0NA和4020进行了对比。实验结果表明，防老剂8PPD对NR，BR和SBR的热氧老化防护能力优于防老剂D和RD，接近防老剂4010NA和4020。防老剂8PPD对3种橡胶的硫化特性有一定的影响。 |
| 英文摘要: |
| The anti-heat and oxidative aging effect of the complex antioxidant 8PPD on NR，BR and SBR compound was investigated through the hot aging and thermal analysis.The result showed that the antioxidant 8PPD was better than antioxidant D and RD，similar to the antioxidant 4010NA and 4020 in terms of the anti-heat and oxidative aging effect on NR，BR and SBR compounds.The antioxidant 8PPD had a certain influence of the curing characteristics of 3 compounds. |
