This paper focused on adding a suitable lubrication effect at the interface between the rubber and mixer chamber wall on reducing the surface wear rate of the mixer chamber wall. In the research process, the contact model between the compound and internal mixer chamber wall was simplified to the pin-on-disc experimental model. The experimental results showed that the friction coefficient and the metal surface wear rate of the mixer chamber were reduced (by approximately 24%) by adding an appropriate amount of antifriction agent in the mixing process, while the comprehensive properties of the compound showed an improvement trend. By analyzing the surface elements of the rubber compound, the MoS with an anti-wear effect on the surface of the rubber compound can form a lubrication mechanism between the rubber, filler, and mixer chamber wall metal. Combined with the result of the comprehensive properties of rubber, which showed that although the appropriate amount of antifriction agent formed a lubrication protection mechanism between the rubber and the inner mixing chamber wall, the mechanism did not affect the friction behavior required for mixing. The study can effectively enhance the effective friction mixing and reduce the wear and power consumption of the mixing chamber caused by excess friction during the mixing process.
本文着重于通过在橡胶与密炼机腔壁界面添加适当的润滑效果来降低密炼机腔壁的表面磨损率。在研究过程中，将胶料与密炼机内膛壁之间的接触模型简化为销盘实验模型。实验结果表明，在混炼过程中添加适量的减摩剂可降低密炼机的摩擦系数和金属表面磨损率（约降低24%），同时胶料的综合性能呈改善趋势。通过分析胶料的表面元素可知，胶料表面具有抗磨作用的MoS可在橡胶、填料和密炼机腔壁金属之间形成润滑机制。结合橡胶综合性能的结果表明，适量的减摩剂虽在橡胶与内混炼腔壁之间形成了润滑保护机制，但该机制并未影响混炼所需的摩擦行为。该研究可有效增强有效摩擦混炼，并减少混炼过程中因过度摩擦导致的密炼机磨损和功耗。
