High-grade high-speed copper wire drawing lubricant and preparation method thereof

Abstract

The invention discloses a high-grade high-speed copper wire drawing lubricant. The lubricant is prepared from following raw materials by weight: 12-15 parts of polyoxyethylated castor oil, 2-3 parts of triethanolamine borate, 1-2 parts of sodium citrate, 2-3 parts of tetradecyl trimethyl ammonium chloride, 1-2 parts of stannous mono-sulphate, 1-2 parts of sodium diisopropyl naphthalene sulfonate, 1-2 parts of carboxymethyl cellulose, 2-3 parts of an antiwear agent and 1000 parts of water. Nano aluminium nitride powder is added into the lubricant, thus promoting heat dissipation, enhancing film-forming property and increasing the processing speed. The lubricant has excellent lubricating property, thus improving the processing precision and the surface smoothness. The consumption of a wire drawing die is low. Threads or wires are protected effectively. Generation of surface quality defect and other phenomena is reduced. The service lifetime of the die can be prolonged. The lubricant has firm film formation, high-temperature resistance, no layering, no degeneration, small viscosity change and long shelf-life.

Description

technical field [0001] The invention relates to the technical field of wire drawing of copper and aluminum wires, and relates to a high-grade high-speed copper wire drawing lubricant 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 processing me...

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 good in lubricity, but the foam is large, the cleanliness is not enough, and the amount of liquid taken away is large.
