| 中文摘要: |
| 研究国产异戊橡胶IR70在全钢载重子午线轮胎内衬层过渡层胶中的应用。结果表明，在内衬层过渡层胶中用并用比30/70的IR70/天然橡胶（NR）并用胶替代全NR，同时减小增粘树脂用量，胶料物理性能变化不大，半成品表面粘性明显提高，胎坯外观合格率升高，轮胎耐久性能略有改善，生产成本降低。 |
| 英文摘要: |
| In this study，domestic isoprene rubber IR70 was applied in the transition layer of inner liner of TBR tire.IR70 was blended with NR by the ratio of 30/70 to replace all NR compounds，and the amount of tackifying resin was reduced.The experimental test results showed that the physical properties of the compound changed little，the surface tack of semi-finished product increased significantly，the quality of green tire appearance was improved，the endurance performance of the tire increased and the production cost was reduced. |
