| 中文摘要: |
| 试验研究丁苯橡胶（SBR）1739在绿色环保轿车子午线轮胎胎面胶中的应用。结果表明：在胎面胶配方中用SBR1739等量替代SBR1723，并调整炭黑/白炭黑并用比以及硅烷偶联剂和促进剂的用量，胶料的门尼粘度增大，300%定伸应力提高，拉断伸长率降低，压缩生热和滚动阻力大幅降低，其他物理性能变化不大；0 ℃下损耗因子（tanδ）增大，而60 ℃下tanδ减小，符合绿色环保轮胎胎面胶的性能要求。试制的205/60R15 91V轿车子午线轮胎强度、耐久和高速性能良好，湿牵引性能和操控性能极佳，油耗低。 |
| 英文摘要: |
| The application of styrene butadiene rubber（SBR） 1739 in the tread compound of green radial tire for passenger cars was investigated experimentally.The results showed that，by using equal weight of SBR1739 to replace SBR1723，and adjusting carbon black/silica ratio and the addition level of silane coupling agent and accelerator，the Mooney viscosity of tread compound increased，the modulus at 300% strain improved，elongation at break decreased，compression heat build up and rolling resistance decreased significantly，other physical properties changed little，tanδ at 0 ℃ increased，and tanδ at 60 ℃ decreased.Its properties reached the requirement of green tread compound.The strength，endurance and high speed performance of finished 205/60R15 91V passenger car radial tire were good.The results of road test showed that，the wet traction and controlling performance of tire were extremely good，and the fuel consumption was low. |
