Effect of Thermostatic Mixing on Properties of Tread Compound Filled with Silica

研究恒温混炼工艺对白炭黑胎面胶性能的影响。结果表明:与原混炼工艺相比,采用恒温混炼工艺可使混炼效率提高5.25%,能耗降低4.41%;胶料的门尼粘度略微提高,焦烧时间略微缩短,但完全可以满足生产工艺要求;硫化胶的300%定伸应力、拉伸强度、撕裂强度和磨耗性能均有明显改善,滚动阻力和动态生热降低。

The effect of thermostatic mixing on the properties of the tread compound filled with silica was studied. The results showed that,compared with the original mixing process,by using thermostatic mixing,the production efficiency increased by 5.25 %, the energy consumption was reduced by 4.41% ;the Mooney viscosity of the compound was slightly higher,and the scorch time was shorter, but it could meet the production requirement. The modulus at 300 % elongation,tensile strength, tear strength and abrasion resistance of the vulcanizates were improved by using thermostatic mixing,and the rolling resistance and dynamic heat build-up were reduced.
