A kind of lubricating oil for aluminum foil rolling, preparation method and application

Abstract

The invention relates to a lubricating oil for aluminum foil rolling. The raw material components and parts by weight are as follows: base oil: 50-94 parts of Fischer-Tropsch synthetic light oil; lubricant: 2-8 parts of polyricinoleate; oily agent : 2‑12 parts of unsaturated fatty acid ester; extreme pressure antiwear agent: 0.5‑3 parts of fatty alcohol ethoxylated phosphate ester or phosphate ester amine salt. The aluminum foil rolling oil of the invention has the characteristics of low viscosity, good lubricity, good low-temperature annealing cleanliness, no corrosion, good processing surface quality, etc., and satisfies the technical requirements of aluminum foil continuous multi-roller finishing rolling.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, in particular to an aluminum foil rolling lubricating oil, a preparation method and an application. Background technique [0002] The aluminum foil rolling process is formed by rolling from thick to thin. It is divided into rough rolling and fine rolling. Generally, the exit thickness is greater than 0.05mm for rough rolling, and the exit thickness is less than 0.05mm for fine rolling. In the manufacturing process, there are multiple rollers for reversible continuous rolling mill process. This process will generate high friction, which will increase the rolling pressure, increase the wear of the rolls, and seriously damage the surface of the aluminum foil, which requires rolling oil for lubrication. [0003] Under the continuous multi-roll finishing rolling process, the thermal deformation and frictional heat of aluminum will increase the temperature of the rolled parts and rolls, which w...
