High-speed wire drawing lubricant used for drawing metal wires and preparation method of the lubricant

Abstract

The invention discloses a high-speed wire drawing lubricant used for drawing metal wires. The lubricant is prepared from following raw materials by weight: 1-2 parts of nanometer titanium dioxide, 2-3 parts of triethyl citrate, 2-3 parts of sodium carbonate, 5-6 parts of soybean oil, 1-2 parts of cobaltous sulfate, 15-25 parts of palm oil, 2-3 parts of sodium petroleum sulfonate, 2-3 parts of sulfurized olefin cottonseed oil, 1-2 parts of a silane coupling agent KH-550, 3-4 parts of vinyl acetate, 2-3 parts of an antiwear agent and 1000 parts of water. Nano aluminium nitride powder is added into wire drawing liquid, thus promoting heat dissipation, enhancing the film-forming property and increasing the processing speed. The lubricant has excellent anti-oxidation and anti-discoloration effects so that a working fluid is not prone to densification or turning blue. The lubricant is suitable for being used at various wire drawing speeds, and especially at a high wire drawing speed not less than 6 m / s. The lubricant is capable of enhancing rust resistance of the wires and can be easily cleaned. The wires drew by utilization of the lubricant have good quality. The service lifetime of a wire drawing die can be prolonged.

Description

technical field [0001] The invention relates to the technical field of wire drawing of copper and aluminum wires, and relates to a high-speed wire drawing lubricant for drawing metal wires and a preparation method thereof. Background technique [0002] In the existing wire drawing process, lubricating oil is mostly used as the wire drawing medium. The surface of the drawn wire is round, delicate, smooth, transparent, free of debris, the broken wire rate is reduced, and the product quality is greatly improved. However, the lubricating oil dissipates heat slowly, damages the mold, and affects product quality. At the same time, the high temperature can easily ignite the oil or cause the oil to evaporate and smoke, resulting in the deterioration of the site environment. [0003] The wire drawing process is a metal processing process. Under the action of pressure, the metal is forced to pass through the mold, the metal cross-sectional area is compressed, and the technical process...

Problems solved by technology

[0004] The main function of the wire drawing fluid is lubrication and cooling, so it is necessary to ensure that the wire drawing fluid has sufficient lubricating effect. Currently, the commonly used wire drawing fluid in the market is not bad in lubricity, but the foam is large, the cleanliness is not enough, and the amount of liquid taken away is large.
