石油基航空润滑油抗氧剂种类和抗氧化机理

Types and Antioxidative Mechanism of Antioxidants in Petroleum Base Aviation Lubricating Oil

添加抗氧剂是减缓航空润滑油氧化变质的有效途径。本文主要介绍了石油基航空润滑油的氧化机理,添加的抗氧剂的主要类型,以及这些抗氧剂的抗氧化机理以及协同作用机理。

At present, adding antioxidants to aviation lubticating oil is an effective way to slow oxidation. The oxidation mechanism of petroleum base aviation lubricating oil （PBALO） was described. The main types of antioxida- nts in PBALO were introduced. The antioxidative mechanism and synergistic effect of these antioxidants in PBALO were summarized.
