| 研究环保型促进剂TBzTD用量和再生时间对废旧轮胎胶粉再生效果的影响。结果表明：随着促进剂TBz-TD用量的增大或再生时间的延长，再生胶的门尼粘度减小，拉伸强度和拉断伸长率先增大后减小；当再生时间为10 min时，随着促进剂TBzTD用量的增大，再生硫化胶的储能模量和损耗模量增大，损耗因子总体呈先增大后减小趋势；当促进剂TBzTD用量为1.69-2.25份、再生时间为1O min时，再生胶的综合性能较好。扫描电子显微镜分析表明，加入促进剂TBzTD的再生硫化胶具有较好的界面结合。 |
| 英文摘要: |
| The influence of the addition level of environmentfriendly accelerator TBzTD and the reclaiming time on the reclaiming results of ground tire rubber were investigated. The results showed that，as the addition level of accelerator TBzTD increased or the reclaiming time extended， the Mooney viscosity of reclaimed rubber decreased， the tensile strength and elongation at break of the vulcanizates increased at first and then decreased. When reclaiming time was 10 min and the addition level of accelerator TBzTD increased， the storage modulus and loss modulus of the vulcanizates increased，and the loss factor tended to increase at first and then decrease. When the addition level of accelerator TBzTD was l. 69一2.25 phr，and the reclaiming time was 10 min，the overall properties of reclaimed rubber was better. SEM analysis results indicated that the vulcanizates with accelerator TBzTD had good interfacial bonding. |
