【摘要】 本文介绍了可生物降解润滑剂抗氧化安定性的研究概况，通过分析汽油机主要摩擦副的摩擦磨损和润滑状态以及可生物降解润滑油在抗氧化安定性和可生物降解性能方面的要求，在润滑理论的指导下和参阅了大量资料的基础上，合理选择了各种添加剂。本文应用均匀设计试验方法，用逐步回归技术对试验结果进行处理，分析了基础油对抗氧剂的感受性及润滑油氧化前后的抗磨性。重点考察了抗氧剂间、抗氧剂与清净分散剂间的协同作用，在此基础上，提出了复合抗氧剂的优化配方。最后进行了研制油与参比油的抗氧化安定性对比试验和研制油的可生物降解性试验。结果表明，研制油不仅具有优良的抗氧性，而且是可生物降解的。更多还原

【Abstract】 In this paper the research general situation of the resisted oxygen capability of biodegradable engine oil is described. The tribology and lubrication characteristic, lubrication mechanism of the main tribo-pairs of gasoline engine and the biodegradable engine oil’ s demands on resisted oxygen capability are analyzed simply. In the paper some additives are chosen reasonable according to the lubrications principal and a lot of data.The uniform design of experiment is used to arrange multi-level and multi-factor experiment. The stepwise technique is adopted to analyze the result. The sensitivity and compatibility among additive and the base oil, and resisted wear capability of engine oil Before the oxide and After the oxide are studied by a series of tests. Interactions among oxidation-corrosion inhibitor, and among oxidation-corrosion inhibitor And The peace and quiet dispersing agent are stress researched. On this foundation the optimum formulation of compound oxidation-corrosion inhibitor is presented. At last, several experiments are made to evaluate the resisted oxygen capability of the developes oil by comparing with the import and the biodegradable capability of the developes oil. The results show that its resisted oxygen capability is equivalent and it is biodegradable.更多还原
