Anticorrosive wire drawing liquid used for metal and preparation method thereof

Abstract

The invention discloses an anticorrosive wire drawing liquid used for metal, and is characterized by comprising the following raw materials by weight: 3-5 parts of sodium alcohol ether sulphate, 1-2 parts of citric acid, 2.5-3 parts of zinc butyl octyl dithiophosphate, 1.5-2.5 parts of diisobutyl phthalate, 3-4 parts of pentaerythritol, 2-3 parts of tributyl phosphate, 8-12 parts of rapeseed oil, 8-10 parts of nanometer titanium dioxide, 1-2 parts of dispersant NNO, 5-7 parts of auxiliary agent and 900-950 parts of deionized water. A formula of the wire drawing liquid is reasonable, the added zinc butyl octyl dithiophosphate has good antioxidant and anti-corrosive property, odor of the wire drawing liquid can be avoided, and service life is prolonged; and the added auxiliary agent has good antiwear, dispersion, lubrication and film forming ability. The aqueous formula is employed, and the wire drawing liquid has the advantages of low flow viscosity and good fluidity, has good heat radiation effect and excellent lubrication performance, the wire type of brass wires and aluminum wires drawn by the product of the invention is uniform, surface is bright, and corrosion is difficult.

Description

technical field [0001] The invention relates to the technical field of wire drawing, in particular to a metal-specific anti-corrosion wire drawing liquid and a preparation method thereof. Background technique [0002] 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 method to obtain the required cross-sectional area shape and size is called the metal wire drawing process. The factors that affect the tensile strength of the wire mainly include the tensile strength and deformation degree of the wire, the friction coefficient between the wire and the grinding hole, the size of the die hole of the wire die, and the position of the wire die. 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, th...

Problems solved by technology

However, the heat dissipation of the lubricating oil is slow, which will damage the mold and affect the 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.

There are many types of wire-drawing agents, and their performance varies greatly. Some wire-drawing lubricants will turn black, deteriorate, and stink during use.
