| 中文摘要: |
| 以全钢载重子午线轮胎用高白炭黑含量胶料配方为基体，研究硅烷偶联剂Si69与活性剂PEG4000协同作用改性白炭黑对胶料性能的影响。结果表明：硅烷偶联剂Si69和活性剂PEG4000对提高白炭黑分散效果不存在协同作用；对降低胶料的门尼粘度、延长t10及提高硫化胶的抗硫化返原率、硬度、定伸应力和降低生热方面存在明显的协同作用；硅烷偶联剂Si69用量为5.2份、活性剂PEG4000用量为3份时，胶料的门尼粘度和硫化胶的生热最低，硫化胶的定伸应力、拉伸强度和拉断伸长率均较高，综合性能较佳。 |
| 英文摘要: |
| Based on the formula of high silica content compound for truck and bus radial tire，the effect of synergistic effect of silane coupling agent Si69 and active agent PEG4000 of silica modification on the properties of cmpound was studied.The results showed that silane coupling agent Si69 and active agent PEG4000 had no synergistic effect on improving the dispersion effect of silica.It had obvious synergistic effect on reducing Mooney viscosity of compound，prolonging t10，and improving the anti-reversion rate，hardness，modulus and reducing heat build-up of vulcanizate.When the amount of silane coupling agent Si69 was 5.2 phr and the amount of active agent PEG4000 was 3 phr，the Mooney viscosity of the compound was the lowest，the heat build-up of the vulcanizate was the lowest，the modulus，tensile strength and elongation at break of the vulcanizate were higher，and the comprehensive property was better. |
