| 研究湿法混炼白炭黑母胶在全钢载重子午线轮胎胎面胶中的应用。结果表明：与采用传统干法混炼白炭黑胶料相比，湿法混炼白炭黑母胶混炼胶的门尼粘度增大，门尼焦烧时间和t90延长，硫化胶的密度增大，邵尔A型硬度、100%定伸应力和300%定伸应力提高，60和80 ℃时的损耗因子略大，白炭黑分散性相差不大；湿法混炼白炭黑母胶胶料混炼减少1段，混炼过程无白炭黑粉尘飞扬，半成品部件尺寸稳定性和质量较好，成品轮胎的耐久性能变化不大，符合国家标准要求。 |
| 英文摘要: |
| The application of the silica masterbatch prepared by wet mixing process in the tread compound of all-steel truck and bus radial tire was studied. The results showed that，compared with the compound prepared by traditional blending process，the Mooney viscosity of wet mixing silica masterbatch compound increased，the Mooney scorch time andand t90 were prolonged，the density increased，the Shore A hardness and modulus at 100% and 300% elongation increased，the loss factor at 60 and 80 ℃ was slightly enlarged，and the dispersion of silica was similar. The wet mixing process had fewer mixing steps comparing with dry process and the silica dust was minimized. By using the masterbatch from wet process，the dimension stability of the semi-finished parts was good，and the durability of the finished tires met the requirements of national standards. |
