Problems solved by technology

At present, most manufacturers of magnesium alloy strips do not use any lubricant in the production process and directly dry-roll, but it will cause defects such as poor surface quality, uneven thickness, and edge cracking of the strip; if full-oil lubricating fluid is used, Although the lubricity and rust resistance are good, the cooling effect is poor, and adverse effects such as sticking of the rolled piece to the roll are prone to occur; at the same time, the lubricating oil seriously pollutes the surface of the plate and strip, and a large amount of magnesium powder particles are produced during the production process, causing huge At the same time, the insulation and heat preservation effect of the roll is not ideal, and the rolling temperature is not stable enough. Therefore, it is necessary to develop an emulsion with uniform oil-water dispersion

Abstract

The invention discloses a magnesium alloy plate and strip rolling emulsion and a preparation method thereof, and relates to the field of lubricants and magnesium alloy plate and strip rolling. The magnesium alloy plate and strip rolling emulsion with lubricating, antirust, cleaning, environmental protection and recycling properties is prepared through selecting pentaerythritol oleate, mixed acid ester of trimethylol propane and PAO-10 as base oil, TX-4 and TX-7 as an emulsifier, butyl stearate and C12-14 alcohol as an oily agent, phosphate ester and nitrogen-containing borate as an extreme pressure agent, triethanolamine and fatty acid alkanolamide as an antirust agent, emulsified silicone oil as an antifoaming agent and phenyl naphthylamine as an antioxidant. The emulsion has the advantages of reduction of damages caused by plate and strip surface adhesion, reduction of the corner cracking of products, wash-off of a large amount of magnesium powder generated in the rolling process, effective improvement of the surface quality and the dimension precision of the products, and reduction of the enterprise's production cost.

Description

technical field [0001] The invention belongs to the technical field of lubrication for rolling plate and strip processing, and in particular relates to an emulsion for rolling magnesium alloy plate and strip and a preparation method thereof. Background technique [0002] Magnesium alloy, as the lightest metal structural material in practical application so far, has been more and more widely used in the fields of automobiles, aerospace, and electronic circuits. Strip rolling is one of the most important deformation methods of magnesium alloys, but there are relatively few studies on the rolling lubrication of magnesium alloys. [0003] During the rolling process of magnesium alloy sheet and strip, due to the friction between the roll and the rolled piece, the phenomenon of "magnesium sticking" occurs, which not only wastes energy, but also reduces the rolling speed. In addition, magnesium is easy to oxidize at high temperature, and magnesium alloy is generally rolled at medi...
