利用正交试验设计考察了EAK、SCO和T304作为极压添加剂在铜板带冷轧乳液中的综合摩擦学性能,分析影响基础油极压抗磨性能的主要因素;研究不同类型的添加剂复配后的协同润滑特征,优选了最佳的复配比例,并通过轧制试验研究极压剂复配体系的工艺润滑效果.结果表明:添加剂影响基础油极压抗磨性能因素大小顺序为EAK>SCO>T304;硫系添加剂SCO和磷系添加剂EAK复配,可以有效提高润滑油的油膜承载能力和极压抗磨性能,当两者添加比例为6∶1时复配体系协同作用效果最佳;以EAK-SCO体系配制的乳化液能有效减少轧制过程的摩擦,降低轧制能耗,铜带轧后表面十分光洁平整,因此在铜板带轧制润滑中具有良好的应用前景.
The orthogonal tribological properties of EAK, SCO and T304 as extreme pressure additives in cold rolled copper clad strip were investigated by orthogonal experimental design. The main factors affecting the extreme pressure and antiwear performance of base oil were analyzed. After the different types of additives were compounded , The optimal compounding ratio was optimized and the process lubrication effect of the extreme pressure agent compounding system was studied through rolling test.The results showed that the order of the factors influencing the extreme pressure and antiwear properties of additives was EAK> SCO > T304. The combination of sulfur-based additive SCO and phosphorous-based additive EAK can effectively improve the oil film carrying capacity and extreme pressure and antiwear performance. When the additive ratio is 6: 1, the synergistic effect is best. The emulsion prepared with EAK-SCO system can effectively reduce the friction during the rolling process and reduce the energy consumption of rolling. The surface of the copper strip is smooth and smooth after rolling. Therefore, it has a good application prospect in rolling and lubrication of copper strip.
