在高档的润滑油中除了加有主抗氧剂ZnDTP外，还需加入其它助抗氧剂以弥补其高温抗氧性的不足。本研究合成了几种有机铜盐高温抗氧剂，用DTA法评价了它们及一些常用抗氧剂对润滑油的热稳定性的影响，发现铜铜盐的高温抗氧性能比一些常用抗氧剂好，可满足高档油的需求。
In addition to high-grade lubricating oil in addition to the main antioxidant ZnDTP, but also need to add other antioxidants to make up for its lack of high-temperature oxygen. In this study, several organic copper salt high temperature antioxidants were synthesized. The effects of them and some common antioxidants on the thermal stability of lubricating oil were evaluated by DTA. It was found that the high temperature oxidation resistance of copper and copper salts is better than that of some commonly used antioxidants Good agent to meet the needs of high-grade oil.
