| 中文摘要: |
| 研究硅烷偶联剂Si747在半钢子午线轮胎胎面胶中的应用。结果表明：在胎面胶配方中以硅烷偶联剂Si747等量替代硅烷偶联剂Si69，并相应调整硫化体系，胶料的门尼焦烧时间和t 10延长，t 90缩短，F L和F max均降低；硫化胶的物理性能稍有降低；胶料中白炭黑的分散性和动态力学性能明显改善；胶料混炼过程中挥发性有机物排放明显减少。 |
| 英文摘要: |
| The application of silane coupling agent Si747 in tread compound of steel-belted radial tire was studied.The results showed that，by using silane coupling agent Si747 to replace equivalently silane coupling agent Si69 in the formula of tread compound，and adjusting the curing system accordingly，the Mooney scorch time and t 10 of the compound were prolonged，t 90 was shortened，F L and F max were decreased，the physical properties of the vulcanizate were slightly decreased.The dispersion of silica in the compound and the dynamic mechanical properties of the compound were improved.The emission of volatile organic compounds in the mixing process was significantly reduced. |
