| 中文摘要: |
| 对夏季超高性能（UHP）轮胎胎面胶分别采用等量替换法和目标值法进行配方设计，考察两种方法对溶聚丁苯橡胶（SSBR）实用性的评价效果。结果表明：将SSBR进行等量替换并通过调节树脂用量设计胎面胶的玻璃化温度在－（6±2） ℃范围内的目标值法针对性地满足UHP轮胎胎面胶关键性能指标需求，可更加有效地对SSBR进行选型；只对SSBR进行等量替换的等量替换法无法客观地评价各SSBR性能的优劣，实用性较差。本研究A—D四个牌号的SSBR中C牌号和D牌号SSBR的抗湿滑性能、干地操纵稳定性和滚动阻力更具优势。 |
| 英文摘要: |
| The tread compound formula of summer ultra high performance（UHP） tire was designed by equal replacement method and target value method respectively，and the evaluation effect of the two methods on the practicability of solution polymerized styrene butadiene rubber（SSBR） was investigated.The results showed that the target value method which substituting SSBR in the same amount and designing the glass transition temperature of tread compound within the range of －（6±2） ℃ by adjusting the resin content met the key performance index requirements of UHP tire tread，and could more effectively select SSBR.The equivalent substitution method which only carried out equivalent substitution for SSBR could not objectively evaluate the performance of each SSBR，and had little practical reference significance.In this study，grades C and D SSBR in SSBR of four grades A—D had more advantages in wet skid resistance，dry handling stability and rolling resistance. |
