| 中文摘要: |
| 研究改性剂OCST在半钢子午线轮胎胎面胶中的应用。结果表明：随着改性剂OCST用量的增大，胶料的门尼粘度增大，硫化速度变化不大，硫化胶的定伸应力呈增大趋势，回弹值逐渐增大，60 ℃时的损耗因子逐渐减小，压缩生热降低，耐磨性能下降；当改性剂OCST用量为0.2份时，胶料的综合性能较优，成品轮胎的滚动阻力降低。 |
| 英文摘要: |
| The application of modifier OCST in the tread compound of steel-belted radial tire was investigated.The results showed that，as the addition level of modifier OCST increased，the Mooney viscosity of the compound increased，the curing rate changed little，the modulus of the vulcanizate tended to increase， the rebound value increased gradually，the loss factor at 60 ℃ decreased gradually，the compression heat build-up and wear resistance decreased.When the addition level of modifier OCST was 0.2 phr，the comprehensive properties of the compound were better，and the rolling resistance of the finished tire decreased. |
