摘　　要：针对再生润滑油基础油在光照下容易发生变色、浑浊甚至出现沉淀技术问题,通过研究不同受阻胺型光稳剂、紫外线吸收剂以及抗氧剂对润滑油光照下光稳定性能,实验提出复合光稳剂添加浓度为:光稳剂770为120mg/L,紫外吸收剂UV-326为150mg/L,抗氧剂264为90mg/L。Under the radiation of sunlight, the rerefined oil will be discolored, muddy or even precipitated. In this paper, the effect of the three different light stabilizer including hindered amine light stabilizer, UV absorber and antioxidant on the light stability of the lubricant base oil was studied under different conditions, such as the addition and combinations, the formula of composite stabilizer is：light stabilizer 770 ： 120mg/L, UV - 326 ： 150mg/L, phenolic antioxidant： 90mg/L.
