| 中文摘要: |
| 试验研究在全钢载重子午线轮胎胎肩垫胶中采用白炭黑来改善胎肩脱层现象。结果表明，在胎肩垫胶配方中使用白炭黑部分替代炭黑，同时加入硅烷偶联剂，可以提高硫化胶的拉伸强度、撕裂强度和弹性，降低硫化胶动态生热和压缩生热，提高轮胎耐久性能，改善轮胎胎肩脱层现象。 |
| 英文摘要: |
| The application of silica in the shoulder pad compound of truck and bus radial tire (TBR) to solve the shoulder separation problem was investigated.The results showed that,by using silica to partly replace carbon black in the shoulder pad compound of TBR tire,and adding silane coupling agent,the tensile strength,tear strength and resilience of the vulcanizates were increased,the dynamic heat build-up and compression heat build-up of the vulcanizates were reduced,the endurance of tire was improved,and the shoulder separation was minimized. |
