Example Embodiment

[0025] Example 1

[0026] A single-phase water-based lubricating fluid for aluminum cold rolling. The water-based lubricating fluid is composed of the following components by weight percentage: polyoxyethylene-polypropylene polymer (molecular weight: 1000) 10%, polyoxyethylene Phosphate ester 1%, benzotriazole 0.5%, and the rest made up with deionized water.

[0027] The preparation method of the above-mentioned single-phase water-based lubricating liquid for aluminum cold rolling, the steps are: first pour half of the above-mentioned polyoxyethylene-polypropylene polymer into a container, and then pour polyoxyethylene phosphate and benzotriazole Pour into containers one by one, heat to 50°C and stir evenly until all components are completely dissolved, and finally add the remaining amount of polyoxyethylene-polypropylene polymer and stir well.

Example Embodiment

[0028] Example 2

[0029] A single-phase water-based lubricating fluid for aluminum cold rolling. The lubricant is composed of the following components by weight percentage: polyethylene glycol (molecular weight: 200) 90%, polyoxyethylene phosphate 1%, benzene Triazole 0.5%, triethanolamine 1.5%, and the rest are supplemented with deionized water.

[0030] The preparation method of the above-mentioned single-phase water-based lubricating liquid for aluminum cold rolling, the steps are: first pour half of the above-mentioned polyethylene glycol into a container, and then pour polyoxyethylene phosphate, benzotriazole and triethanolamine in sequence Pour into a container, heat to 50°C and stir evenly until all components are completely dissolved, then add the remaining amount of polyethylene glycol and stir well.

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. [000...
