添加剂在植物基基础油中的抗氧抗磨性

通过分析植物基基础油的生物降解性和使用性能的要求, 合理选用基础油及添加剂, 在均匀设计的基础上安排多因素多水平试验, 用逐步回归技术通过计算机对试验结果进行处理, 以此分析基础油对添加剂的感受性及添加剂的配伍性。在重点考察基础油的抗氧抗磨性的基础上, 得出复合添加剂的最佳配比为M_T202∶M_T203∶M_T204∶M_DNA∶M_CuDTP∶M_T115A∶M_T152为2∶4∶8∶6∶1∶16∶24;最佳加量范围为3%~5%。最后进行了研制油与参比油的性能对比试验, 结果表明, 研制油的抗氧抗磨性优于同类矿物基润滑油, 而且可生物降解。

Antioxidant and antiwear property of additives in vegetable base oil

By analyzing the vegetable base oil demands on the lubrication mechanism and biodegradable performance, base oil and additives were chosen reasonably. The uniform design was used for arranging multi-level and multi-factor tests, and the stepwise technique was adopted to analyze the datum by computer.The sensitivity and compatibility among additives and base oil are studied by a series of tests.The optimal proportion and the amount of the additives are pointed out: MT202∶MT203∶ MT204∶ MDNA∶ MCuDTP∶ MT115A∶ MT152 is 2∶4∶8∶6∶1∶16∶24, their amount is among 3% to 5%. At last, several experiments were made to evaluate the property of formulation by comparing with petrolatum-based lubricant. The results show the former has better antioxidant and antiwear property, and it is biodegradable.
