Water-base lubricating fluid for aluminum cold-rolling and preparation method thereof

Abstract

The invention discloses a water-base lubricating fluid for aluminum cold-rolling, which comprises the following components in percentage by weight: 5-99% of water-soluble polymer, 0.1-2.0% of lubricant additive, 0.05-5% of functional additive and the balance of deionized water. The invention also discloses a preparation method of the water-base lubricating fluid. The water-base lubricating fluid disclosed by the invention overcomes the defects in pure oil and emulsion, and can ensure the rolling safety and effective control on oil consumption on the premise of providing favorable rolling effect.

Description

technical field [0001] The invention relates to a water-based lubricant for aluminum cold rolling and a preparation method thereof. Background technique [0002] Aluminum cold rolling is an important process content in aluminum processing. Among them, lubricating fluid is an important factor to ensure its continuous operation and rolling quality. In the traditional cold rolling process, pure oil or emulsion is generally used for rolling. But both lubricants have obvious advantages and disadvantages. [0003] First of all, for pure oil rolling, it can provide high-quality rolled board surface quality, but most of these products have a low boiling point, which is extremely volatile and can cause fires. Moreover, the fuel consumption is large, resulting in high rolling costs. [0004] The emulsion product does not have the above two defects, but due to its poor lubricating performance, the quality of the rolled board surface cannot be compared with that of pure oil.

Problems solved by technology

However, both lubricants have obvious advantages and disadvantages.

[0003] First of all, for pure oil rolling, it can provide high-quality surface quality after rolling, but most of these products have a low boiling point, which is extremely volatile and can cause fire

Moreover, the fuel consumption is large, resulting in high rolling costs

[0004] The emulsion product does not have the above two defects, but due to its poor lubricating performance, the quality of the rolled board surface cannot be compared with that of pure oil.

[0005] At the same time, such products generally contain a large amount of surfactant components, which can easily emulsify system miscellaneous oil into the lubricating fluid system, which will further reduce the rolling effect
