| 中文摘要: |
| 研究促进剂MTT对硫黄调节型氯丁橡胶（CR）性能的影响，并与促进剂ETU进行对比。结果表明：随着促进剂MTT用量增大，硫黄调节型CR焦烧时间延长，硫化速度加快，定伸应力和拉伸强度提高，耐磨性能和弹性变化不大，耐热空气老化性能改善；与促进剂ETU相比，促进剂MTT胶料的加工安全性能好，硫化速度快，胶料物理性能相差不大，且符合环保要求。促进剂MTT可替代促进剂ETU用于硫黄调节型CR中。 |
| 英文摘要: |
| The influence of curing accelerator MTT on the properties of sulfur modified CR was investigated and compared with accelerator ETU. The experimental test results showed that with the increase of MTT amount， the scorch time of the compound was extended， the curing speed increased， the modulus and tensile strength of the vulcanizates increased， the wear resistance and resilience changed little， and the heat aging properties were improved. Compared with ETU， the processing properties of the compound with MTT were better， the curing speed was faster， the physical properties of the vulcanizates were similar and the product met the requirements of environmental regulations. It was concluded that MTT could be applied to replace ETU in the sulfur modified CR compound. |
