| 中文摘要: |
| 研究改性锦纶短纤维在高性能轿车子午线轮胎胎面胶中的应用。结果表明：改性锦纶短纤维替代部分炭黑后，混炼胶的硫化速度加快，焦烧时间缩短；硫化胶的密度减小，压缩疲劳温升降低，60 ℃的损耗因子（tanδ）减小，撕裂强度增大，但拉伸强度和耐磨性能有所下降，且变化趋势随着改性锦纶短纤维用量的增大而增大。采用6份改性短纤维替代4份炭黑用于胎面胶配方，胶料的温升降低1～2 ℃，60 ℃的tanδ值减小；成品轮胎的高速和耐久性能均提高，滚动阻力降低。 |
| 英文摘要: |
| In this study，application of modified nylon short fiber in the tread compound of high performance passenger car radial tire was investigated.The results showed that，as the carbon black was partly replaced by modified nylon short fiber，the curing rate of the rubber mix increased and scorch time was shortened，density of the vulcanizates decreased，heat build-up and tanδ（60 ℃）decreased，tear strength was increased，but tensile strength and wear resistance decreased，and the change magnitude increased as the addition level of modified nylon short fiber increased.By using 6 phr modified short fibers to replace 4 phr carbon black in the tread compound，the heat build-up decreased by 1～2 ℃，both high speed performance and endurance performance of the test tire were improved，and rolling resistance was lower. |
