%X 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t<sub>90</sub>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。;The application of wet mixing silica masterbatch in tread compound of all-steel truck and bus radial tire was studied.The results showed that，compared with the traditional dry mixing sillica compound，the Mooney viscosity of wet mixing silica masterbatch compound was increased，the Mooney scorch time and t<sub>90</sub> were prolonged，the density was increased，the Shore A hardness and modulus at 100% and 300% elongation were increased，the loss factor at 60 and 80 ℃ was slightly enlarged，and the dispersion of silica had little difference.The number of mixing sections of wet mixing silica masterbatch compound was reduced by one section，no silica dust was flying in the mixing，the size stability of semi-finished parts was good，and the durability of finished tires had little change，which met the requirements of national standards
