摘　　要：在 3 5 0SN基础油中考察油溶性羧酸铜对二烷基二硫代磷酸锌 (T2 0 2 )抗氧化性能的影响。结果表明 ,T2 0 2 与铜剂复合后在温度较低的氧化试验中抗氧化效果变差 ,在温度较高的试验中则具有协同抗氧性 。The antioxidant properties of the oil carboxylic-acid copper on Zinc Dialkyl Dithiophosphate(T 202 ) in 350 SN base oil have been investigated. The results indicate that the antioxidant properties of T 202 through its combination with the copper additive can be enhanced in higher temperature oxidation tests,and decreased in lower temperature tests,which is related with the antioxidant properties of the copper additive.
