Abstract: The performance of copper foil rolling oil has a profound impact on the product quality. A variety of straight chain alcohols, esters and new phosphoric acid amines (CAP) and azoles corrosion inhibitors is applied as the main additives to produce a new generation of copper foil rolling oil CFCO. The tribological performance of CFCO and its corrosion inhibition properties were studied. The lubrication performance was comprehensively investigated with a cold rolling test in a commercial scale. The results show that the CFCO copper foil rolling oil has excellent tribological properties, significantly reducing surface roughness, increasing the uniformity of surface morphology; at the same time, it has a good corrosion inhibition performance which can be used to resolve the problems in rolled surface oxidation and discoloration and increase surface quality of products.

Key words: rolled copper foil, rolling oil, friction and wear, corrosion inhibition
