Improved copper rolling oil and additive thereof

The invention discloses a composite additive of copper rolling oil. The composite additive comprises benzotriazole phosphate and benzotriazole borate, and the benzotriazole phosphate ester is selected from benzotriazole dithiophosphate ester compounds. In addition, the invention further discloses copper rolling oil using the composite additive. Compared with the prior art, when the composite additive is used in the improved copper rolling oil, not only is the bearing capacity improved, but also the antifriction performance is remarkably improved. 公开了一种铜轧制油的复合添加剂，包括苯并三唑类磷酸酯和苯并三唑类硼酸酯；苯并三唑类磷酸酯选自苯并三唑类二硫代磷酸酯化合物。此外，还公开了使用该复合添加剂的铜轧制油。与现有技术相比，改进的铜轧制油使用所述复合添加剂时，不仅提高了承载能力，而且显著改善了减摩性能。
