摘　　要：分析了常用矿物油抗氧剂的作用机理 ,从可生物降解润滑油对添加剂的要求出发 ,选择了T2 0 3、T70 6、CuDTP、DNA等常用抗氧剂 ,通过试验考察了以菜籽油为原料的汽油机基础油对单一抗氧剂的感受性 ,采用均匀试验设计分析了抗氧剂之间的复合性能 ,提出几种抗氧剂的最佳配比为 :DNA∶T70 6∶CuDTP∶T2 0 3=4 9∶1∶1∶16。The mechanism of general oil antioxidants were analyzed.Taking the requirement of biodegradable oil to additives into account,antioxidants such as T203,T706,CuDTP, DNA were chosen,the sensitivities of rapeseed gasoline base oil to single antioxidant were tested,the compound properties between antioxidants were studied by even design experiment method.The optimum ratio of several antioxidants are pointed out,DNA∶T706∶CuDTP∶T203 = 4.9∶1∶1∶16.
