有机铜作为润滑油高温抗氧剂的研究

Study of organic copper salts as antioxidants in lubricating oils

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。

Anti-oxidative inhibitors are often used to formulated high quality engine oils in addition to the base inhibitors ZnDTP. In this work several antioxidative inhibitors have been prepared and evaluated by means of DTA. The copper salts show good results.
