Copper and aluminum wire drawing oil and preparation method and use method thereof

Abstract

The invention relates to the technical field of petroleum base lubricant composition and a preparation method thereof, which is copper and aluminum wire drawing oil and a preparation method thereof. The copper and aluminum wire drawing oil comprises base oil, an emulsifying agent, an auxiliary emulsifying agent, a defoaming agent, an antirusting agent, a preservative and an antiwear agent. The preparation method can be carried out by the following steps that: the copper and aluminum wire drawing oil is mixed into 3 percent to 45 percent of water-based emulsion according to the weight percentage. The water-based emulsion is showered into a wire drawing die cavity in the copper and aluminum wire drawing process. The product of the invention has good lubricating property, excellent light stability and storage stability, low cost, good cooling effect, fast heat-transfer speed, little temperature-rise amplitude, nonflammability and easy cleaning, thus guaranteeing safety of use environment. Copper wires and aluminum wires which are drawn by adopting the product have even line shapes, bright surfaces, and rustless property, and also have good ultraviolet and storage stability and good stability.

Description

technical field [0001] The invention relates to the technical field of a petroleum-based lubricant composition and a preparation method thereof, and relates to a copper-aluminum wire drawing oil and a preparation method thereof. Background technique [0002] Copper wires (wires) and aluminum wires (wires) are the main transmission wires for power transmission in the power industry. They are usually made by drawing process, that is, metal wires with large diameters such as steel wires pass through the pores of the mold and are pulled out under the action of external force to cut them off. The area is reduced to form a wire of the desired diameter. For those with a forming diameter below 1.8mm, the wet drawing method is usually used, that is, the drawing method using lubricating oil as the lubricating medium. This method uses a water-based lubricant, which not only has a good cooling effect on the copper and aluminum blanks and molds, but also solves the problem The dry drawi...

Problems solved by technology

Oil-based lubricant technology, its raw materials are base oil, emulsifier and other anti-corrosion, anti-oxidation and other additives. The lubricating oil composition is used directly, which is expensive and wastes a lot of petroleum resources. Although it has a good lubricating effect, it is difficult to A large amount of heat generated in the metal processing process is quickly removed, the cooling effect is poor, and the lubricating oil is not easy to biodegrade, and the environmental friendliness is poor; the water-based lubricant technology uses synthetic functional additives soluble in water, and then adds other anti- Abrasives are prepared as lubricating fluids. Although water with a large specific heat can quickly remove the heat generated during processing, its film-forming performance on the metal processing surface is poor and its bearing capacity is low, so it is difficult to achieve the ideal lubrication effect.
