| 中文摘要: |
| 研究防肩空剂ST在全钢载重子午线轮胎胎肩垫胶中的应用。结果表明：在胎肩垫胶中采用防肩空剂ST等量替代白炭黑/偶联剂Si69体系，胶料的硫化特性和硫化胶的物理性能变化不大，压缩生热降低；成品轮胎的耐久性能提高，实际行驶里程增加，肩空发生率降低。 |
| 英文摘要: |
| The application of additive ST in the shoulder compound of truck and bus radial tire in order to reduce shoulder separation issue was studied.The results showed that，by using additive ST to replace equal amount of coupling agent Si69 modified silica in the shoulder compound，the curing behavior of the compound and physical properties of the vulcanizates changed little，and the compression heat build up decreased.As a result，the endurance performance of the finished tire was improved，tire mileage increased，and the defect rate of shoulder separation decreased. |
