| 中文摘要: |
| 利用傅立叶转换红外光谱法原位跟踪NR传统硫黄硫化体系的硫化过程，研究新型抗硫化返原剂Z-500对NR胶料硫化过程的影响。试验结果表明，在硫化返原过程中，NR主链上形成了共轭多烯结构，抗硫化返原剂Z-500可与共轭多烯结构发生反应，减小共轭多烯的数量，从而抑制硫化返原。 |
| 英文摘要: |
| The vulcanization course of NR with traditional sulfur curing system was tracked in situ by FTIR and the effect of the new anti-reversion agent Z-500 on the vulcanization of NR was investigated.The test results showed that the conjugated polyene formed on the molecular chains of NR during reversion course，and the anti-reversion agent Z-500 could react with the conjugated polyene to inhibit the reversion. |
