| 中文摘要: |
| 研究噻唑类促进剂M与次磺酰胺类促进剂CZ，NS，TBSI，DZ对天然橡胶（NR）性能影响的差异。结果表明：次磺酰胺类促进剂胶料的加工安全性能、抗硫化返原性能、拉伸性能和耐磨性能均优于噻唑类促进剂胶料；促进剂TBSI兼顾了胶料加工安全性能好、交联密度大和硫化速度快的优点，是一种优秀的促进剂；促进剂DZ有产生亚硝胺致癌物的风险，其胶料物理性能和耐磨性能也较差，应谨慎使用。 |
| 英文摘要: |
| The effect of different accelerators on the properties of NR was investigated.The studied accelerators included thiazole accelerator M and sulfonamide accelerator CZ，NS，TBSI，and DZ.The experimental testing results showed that，with sulfenamide accelerators，the processing safety，anti-reversion properties，tensile properties and wear resistance of the compounds were better than that with thiazole accelerator.The compound with TBSI showed good processing properties，high crosslink density and fast curing speed.The compound with DZ showed poor physical properties and wear resistance while DZ presented the risk of producing carcinogenic nitrosamines. |
