| 中文摘要: |
| 研究硅烷改性液体聚丁二烯橡胶ST-E60（简称ST-E60）在冬季轿车轮胎胎面胶中的应用。结果表明：与环保芳烃油（TDAE）相比，ST-E60的相对分子质量增大，硫含量减小，玻璃化转变温度降低；在冬季轿车轮胎胎面胶中以ST-E60等量替代TDAE，胶料的硫化特性相当，填料的分散性提高，硫化胶的300%定伸应力和回弹值增大，生热降低，耐磨性能提高；成品轮胎的高速和耐久性能达到国家标准要求，雪地抓着性能提高，抗湿滑性能相当，滚动阻力降低。 |
| 英文摘要: |
| The application of silane-modified liquid polybutadiene rubber ST-E60（abbreviated as ST-E60） in the tread compound of winter passenger tire was studied.The results showed that compared with environmentally friendly aromatic oil（TDAE），the relative molecular weight of ST-E60 was increased，the sulfur content was decreased and glass transition temperature was lower.When ST-E60 was used as an equivalent substitute for TDAE in the tread compound of winter passenger tire，the vulcanization characteristics of the compound were comparable，the dispersion of filler improved，the 300% modulus and rebound value of the vulcanizate increased，while heat built-up decreased and wear resistance improved.The high-speed and durability performance of the finished tires met national standards，the snow grip performance improved，wet skid resistance was comparable and rolling resistance reduced. |
