| 中文摘要: |
| 研究芳纶短纤维在轿车子午线轮胎胎面胶中的应用。结果表明：在轿车子午线轮胎胎面胶中直接加入芳纶短纤维，胶料性能较差，且芳纶短纤维用量越大的胶料性能越差；添加分散剂TNB88并采用恒温密炼工艺后，添加芳纶短纤维的胶料门尼粘度和门尼焦烧时间变化不大，硫化速度加快，强伸性能、耐磨性能、压缩疲劳性能、抗切割性能、炭黑分散性能和动态力学性能均较好，其中添加2份芳纶短纤维的胶料比添加4份芳纶短纤维的胶料综合性能更好。 |
| 英文摘要: |
| The application of aramid short fiber in the tread compound of passenger car radial tire was studied.The results showed that with the direct addition of aramid fiber into the tread compound，the properties of the compound were poor，and the properties became worse with increased fiber content.With the addition of dispersing aid TNB88 and constant temperature mixing process，the Mooney viscosity and Mooney scorch time of the compound with aramid fiber changed little，the curing speed increased，and the tensile properties，wear resistance，compression fatigue property，cutting resistance，carbon black dispersion and dynamic mechanical properties of the compound were good.It was found that the properties of the compound with 2 phr of aramid fiber were better than those of the compound with 4 phr of aramid fiber. |
