High-cleanness and environment-friendly copper plate strip rolling oil

Abstract

The invention discloses high-cleanness and environment-friendly copper plate strip rolling oil which is prepared by mixing 7# hydrogenated white oil, 32# hydrogenated white oil, dioctyl sebacate, C12-C14 alcohol, 2,6-di-tert-butyl-p-cresol and a benzotriazole derivative. The product is narrow in distillation range and excellent in cleaning performance; and the product permeability is good, the rolling speed can be greatly increased, and the rolling machining efficiency of equipment is improved.

Description

technical field [0001] The invention relates to a copper strip rolling oil. Background technique [0002] Copper plate and strip rolling oil is mainly used in the rolling process of copper plate and strip to lubricate, cool, clean, and prevent corrosion, so that the copper plate and strip can obtain higher precision and better finish. [0003] There are more than 300 copper plate and strip production enterprises in my country, with an annual output of more than 3 million tons (of which the annual output of high-precision strip exceeds 1 million tons). In recent years, with the continuous expansion of enterprise scale and continuous improvement of equipment level (key strip processing enterprises all adopt internationally advanced equipment imported from Germany, Japan, etc.), therefore, the performance and quality requirements for copper plate and strip rolling oil are also required. Higher and higher. [0004] In the rolling process, the copper plate and strip are difficu...

AI Technical Summary

Problems solved by technology

However, the currently commercially available copper strip rolling oils generally have a wide distillation range (initial boiling point ≤ 240°C, final boiling point ≥ 400°C), poor cleanliness, and more oil residue on the surface of the strip after heat treatment, which seriously restricts the copper strip rolling oil. The improvement of the surface finish of the strip (this is also a long-standing and difficult problem for domestic copper strip processing enterprises)

In addition, the following two problems of the copper plate and strip rolling oil currently available in the market need to be solved urgently: one is the poor permeability, which leads to a slow rolling speed (generally lower than 120m / min), which seriously affects the equipment Second, the formula generally contains toxic and harmful substances such as aromatic compounds, which affects environmental safety and human health
