摘  要:以地沟油为原料,制备了一种油溶性有机稀土化合物(ORE),并通过红外光谱和等离子发射光谱对其化学结构和元素组成进行了表征。用万能摩擦磨损试验机考察了有机稀土化合物在液体石蜡中的摩擦学性能,结果表明:有机稀土化合物作为润滑添加剂具有比ZDDP更好的抗磨减摩性能,有望作为新型的环境友好型润滑添加剂在工业实际中得到应用。当基础油中加入1.0%ORE时,其减摩性能和抗磨性能分别提高23%和34%,其承载能力是基础油的2.4倍。分析认为有机稀土化合物在摩擦过程中形成的含稀土的边界润滑膜可能是其具备良好极压抗磨和减摩效果的主要原因。由地沟油制备环境友好型润滑添加剂,是探索地沟油资源化利用技术的有益尝试,具有良好的推广应用前景。A novel oil soluble organo rare-earth( ORE) was prepared by illegally waste-cooking oil as a raw material. The chemical features and elemental composition of ORE were confirmed by IR and ICP. The tribological behaviors of ORE as lubricating oil additive in liquid paraffin were evaluated with a multifunctional friction and wear tester. The results showed that ORE exhibited better anti-wear behavior and friction-reducing capacity in the base stock than that of ZDDP,which indicated that ORE may be applied as an environment-friendly and multifunctional lubrication additive in industrial field. When 1. 0 % ORE was added,its friction-reducing and anti-wear capacities increased 23 % and 34 % individually,and its load-carrying capacity was 2. 4 times that of base stock. The excellent performance of ORE maybe attribute to the formation of a boundary lubricating film mainly composed ofrare-earth compounds on the rubbed surface which lubricated by lubricant contained ORE additive. The preparation of environment-friendly lubricating additives industrial products by illegally recycled waste-cooking oil,was a beneficial attempt to solve the resource utilization technology of illegally recycled waste-cooking oil,which perhaps has good popularization and application prospect,which perhaps has good popularization and application prospect.
