A kind of extreme pressure type aluminum strip hot rolling emulsion and preparation method thereof

Abstract

The present invention is an extreme-pressure hot-rolled emulsion for aluminum plate and aluminum strip, which is composed of refined vegetable oil, hydrogenated naphthenic base oil, environmentally friendly synthetic ester, biodegradable high-efficiency composite nonionic emulsifier, composite antioxidant, and extreme-pressure antiwear agent , corrosion inhibitor, defoamer, preservative, wetting agent, bactericide, composite antioxidant is made up of phenol-based antioxidant, anilino antioxidant and alkenoic acid antioxidant, the present invention also provides above-mentioned thermal Preparation method of rolling emulsion. The invention has excellent biological emulsion stability, excellent hot-rolling lubricating performance, excellent thermal separation performance, excellent anti-corrosion performance of aluminum plate and aluminum strip, no cracking and blackening of aluminum plate and aluminum strip, easy cleaning, and effective improvement of aluminum plate and aluminum strip. Strip surface quality, low product consumption, effectively extending the service life of the roll, stable emulsion, easy operation, easy maintenance, effectively improving the service life and efficiency of the rolling mill, and effectively improving the yield and good rate of aluminum sheets and strips.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an extreme pressure emulsion used in hot rolling of aluminum sheets and strips, in particular to an extreme pressure emulsion for hot rolling of aluminum sheets and strips and a preparation method thereof. Background technique [0002] Hot-rolling emulsion is an essential additive in the hot-rolling process of aluminum sheets or strips. During hot rolling, aluminum strips and rolls are rolled under conditions of high temperature, high pressure, and high friction. Therefore, during hot rolling, an emulsion with both cooling and lubricating effects must be used as a cooling lubricant to form a uniform lubricating layer on the surface of the roll and avoid direct contact between the roll and the aluminum plate. The performance of the emulsion largely determines the The quality of hot rolled aluminum sheet and strip. The aluminum industry, including the aluminum processing industry...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a kind of extreme pressure hot-rolled emulsion of aluminum plate and aluminum strip, and the described extreme-pressure type aluminum plate and aluminum strip hot-rolled emulsion should solve the problem that the aluminum plate and aluminum strip in the prior art are prone to cracking during hot rolling , blackening phenomenon, the surface of aluminum plate and aluminum strip is not easy to clean, the surface of aluminum plate and aluminum strip has poor corrosion resistance, the stability of the emulsion itself is poor, the lubrication performance is poor during hot rolling, the product consumes high in use, and at the same time affects the service life of the roll. Technical problems that can also cause serious damage to the environment and ecology
