Abstract

The invention discloses cold rolling oil for aluminum strips, and a preparation method and application thereof. The invention mainly aims to solve the technical problem of poor annealing detergency ofconventional cold rolling oil for aluminum strips. The cold rolling oil for aluminum strips provided by the invention comprises the following components in parts by weight: 5-20 parts of base oil, 50to 80 parts of a long-chain fatty alcohol, 10 to 35 parts of a long-chain fatty acid ester and 0.2 to 2 parts of an antioxidant, wherein the long-chain fatty alcohol is a mixture of fatty alcohols with alkyl groups having 8-18 carbon atoms; the long-chain fatty acid ester is a mixture of fatty acid esters with alkyl groups having 8-22 carbon atoms; and the base oil is narrow-fraction poly-alpha olefin synthetic oil or refined mineral oil with a distillation range of less than 70 DEG C, a closed-cup flash point of more than 80 DEG C and kinematic viscosity of 1.0-4.0 mm<2> / s at 40 DEG C. According to a technical scheme in the invention, the above problem is well solved, and the cold rolling oil is used in an aluminum strip cold rolling process.

Description

technical field [0001] The invention relates to a rolling oil for cold rolling of aluminum strips, a preparation method and application. Background technique [0002] Aluminum cold rolling oil plays the role of lubrication, cooling and cleaning in the process of aluminum cold rolling, and has an important influence on the surface quality of aluminum strips. Rolling oil is mainly based on base oil, supplemented by appropriate amount of additives. Among them, additives are one of the most economical and effective ways to improve the performance of rolling oil. Adding a certain amount of polar additives to non-polar rolling oil can reduce friction and improve the strength of oil film. Considering the process characteristics of aluminum cold rolling and the annealing surface quality requirements of aluminum after rolling, the additives should focus on lubricity and annealing cleanliness. [0003] Chinese invention patent ZL96114016.X discloses an annealing detergency aluminum ...
