用蜡膏稠化成品润滑油是生产烃基润滑脂的传统方法．基于对减压馏分油的结构及化学组成的分析，提出了直接采用减压馏分油制备烃基润滑脂的新方法，并制备出合格的烃基润滑脂．对制备烃基润滑脂的合理工艺流程及影响产品性能的主要工艺因素进行了分析，提出了合理的工艺条件． Thickened waxy finished lubricants are the traditional method of producing hydrocarbon-based greases. Based on the analysis of the structure and chemical composition of vacuum distillate, a new method of preparing hydrocarbon greases by vacuum distillation was proposed and the qualified hydrocarbon greases were prepared. The reasonable process of preparation of hydrocarbon grease and the main process factors affecting the performance of the product were analyzed, and the reasonable process conditions were put forward.
