| 中文摘要: |
| 研究新型封端巯基硅烷偶联剂Si-818在轮胎缓冲层胶料中的应用。结果表明，与添加硅烷偶联剂Si69的胶料相比，添加硅烷偶联剂Si-818胶料的Payne效应弱，白炭黑在橡胶中的分散性较好，混炼胶的门尼粘度减小，t10延长，Fmax－FL增大，硫化胶的100%定伸应力和拉伸强度略增大，压缩疲劳温升较低，屈挠裂纹长度减小，耐屈挠疲劳性能提高。 |
| 英文摘要: |
| The application of a novel end-capped mercapto silane coupling agent Si-818 in breaker compound of tire was investigated.The results showed that compared to the compound with silane coupling agent Si69，the Payne effect of the compound with silane coupling agent Si-818 was weaker，indicating better dispersion of silica in rubber，the Mooney viscosity of the compound with silane coupling agent Si-818 decreased，t10 was prolonged，and Fmax－FL increased，the 100% modulus and tensile strength of the vulcanizate slightly increased，the fatigue temperature rise was lower，the flex crack growth was reduced，and the flex fatigue resistance was improved. |
