Extreme pressure type aluminium plate and aluminum tape hot rolling emulsion and preparation method thereof

Abstract

The invention discloses an extreme pressure type aluminium plate and aluminum tape hot rolling emulsion which consists of refined vegetable oil, hydrogenation naphthene base oil, environment-friendly synthetic ester, a biodegradable efficient compound nonionic emulsifier, a compound antioxidant, an anti-wear reagent at extreme pressure, a corrosion inhibitor, a defoaming agent, a preservative, a wetting agent and a bactericide, wherein the compound antioxidant consists of a phenolic antioxidant, a phenylamino antioxidant and an olefine acid antioxidant. The invention further provides a preparation method of the hot rolling emulsion. The hot rolling emulsion has good biological emulsion stability, excellent hot rolling lubricating property, excellent thermal separation property and excellent aluminium plate and aluminum tape corrosion resistance; an aluminium plate and an aluminum tape have no crack or nigrescence, and are easy to clean, so that the surface qualities of the aluminium plate and the aluminum tape are improved effectively; the hot rolling emulsion is low in consumption; the service life of a roll is prolonged effectively; the hot rolling emulsion is stable; the operation is convenient; the maintenance is easy; the service life and the efficiency of a rolling mill is prolonged and improved effectively; and the yields and excellent and good rates of the aluminium plate and the aluminum tape are increased effectively.

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
