Water-based copper wire drawing liquid with excellent lubricity and preparation method of water-based copper wire drawing liquid

Abstract

The invention discloses a water-based copper wire drawing liquid with excellent lubricity. The water-based copper wire drawing liquid is characterized by comprising raw materials by weight: 1 to 2 parts of dichloro-tetrafluoromethane, 3 to 4 parts of propylene glycol, 0.8 to 1.5 parts of hydrofluoric acid, 1 to 2 parts of tea saponin, 2 to 3 parts of tritolyl phosphate, 2.5 to 4 parts of ricinolic acid polyester, 7 to 9 parts of SN 150 base oil, 3 to 4 parts of peregal O, 1 to 2 parts of methyl benzotriazole, 5 to 7 parts of nano aluminum oxide, 1 to 2 parts of melamine cyanurate, 5 to 7 parts of additives, and 900 to 950 parts of deionized water. The water-based copper wire drawing liquid is reasonable in formula, is low in flow viscosity and high in flowability and cooling performance by adopting a water-based formula, is favorable in lubricity by additionally adopting melamine cyanurate, is favorable in wear resistance, dispersity, lubricity and film-forming property by adopting the additives, and can form a protecting film on the surface of metal when being used with a surfactant. A copper wire drawn with the water-based copper wire drawing liquid is uniform in line font, bright in surface, and low in rust possibility.

Description

technical field [0001] The invention relates to the technical field of wire drawing, in particular to an aqueous copper wire drawing liquid with excellent lubricity 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] Copper wire (wire) is the main transmission wire for power transmission in the power industry. It is usually made by drawing process, that is, a metal wire with a large diameter such as steel wire passes through the hole of the...

Problems solved by technology

There are many kinds of lubricants used for copper wire drawing, and the performance varies greatly. Some wire drawing lubricants will turn black and smelly during use.

There are also some copper wire drawing lubricants that have adverse conditions such as increased tensile force, increased friction, increased oil temperature, increased oil consumption, fast loss of molds and tower wheels, and increased copper powder, which will cause the surface quality of the drawn wire to decrease, which is serious. It affects the quality of the drawn copper wire, so in order to improve the quality of the wire and save costs, it is particularly important to choose and use copper wire drawing lubricants reasonably
