Fully-synthetic drawing fluid for coarse drawing of copper and use method thereof

Abstract

The invention relates to a fully-synthetic drawing fluid for coarse drawing of copper and a use method thereof. The drawing liquid comprises the following raw materials in parts by weight: 5-25 partsof a lubricant, 1-7 parts of a regulating acid, 4-11 parts of boric acid, 4-11 parts of organic alcohol amine, 4-11 parts of ethylene glycol, 4-11 parts of an antirust agent, 1-7 parts of a diethyleneglycol monobutyl ether coupling agent, 0.1-2 parts of a hard water resistant agent, 1-6 parts of a copper corrosion inhibitor T706, 0.01-0.16 part of an organic silicon defoamer and 1-4 parts of a bactericide, with the balance being water. After the drawing liquid prepared by the method is mixed with water according to a certain proportion, the effects of emulsified oil and microemulsion can be achieved when the lubricating property is tested on a German Microtap tapping torque machine, and the field actual use is completely free from problems; in the use process of the drawing liquid, no floating oil problem exists, cleaning is easy, copper powder is easy to settle and filter, only subsequent addition is needed, replacement is not needed, no waste liquid is discharged, and environmentalpollution is reduced.

Description

technical field [0001] The invention relates to the technical field of copper wire drawing lubrication in the wire and cable industry, in particular to a fully synthetic copper wire drawing liquid and a method for using the same. Background technique [0002] Copper wire drawing refers to the technical processing method in which the copper wire busbar wire is forced through the mold under pressure to obtain the required cross-sectional area shape and size, and the wire drawing liquid is an indispensable auxiliary material in the wire drawing process. Its main function It plays the role of lubrication, cooling and anti-rust in the drawing process of large drawing, medium drawing, small drawing and micro drawing of various copper wires, and also protects the wire and mold to achieve a good drawing effect. Among them, copper drawing accounts for the largest proportion and consumes the most drawing liquid. The quality of the wire drawing fluid directly affects the wire drawing ...

AI Technical Summary

Problems solved by technology

The quality of the wire drawing fluid directly affects the wire drawing effect. The wire drawing fluid with excellent performance can protect the mold very well and reduce the phenomenon of wire breakage and mold wear. On the contrary, it will seriously affect the wire drawing quality. With the application of the wire drawing process, the market The quality requirements for wire drawing liquid are getting higher and higher. The existing copper wire drawing liquid mainly uses emulsion or microemulsion products containing mineral oil system, which has problems such as poor emulsion stability, corrosion of metal wires, high energy consumption, and difficulty in cleaning. , which restricts the quality of wire drawing and drawing, it is urgent to improve its formula and process to make it more efficient, environmentally friendly, free of mineral oil, and easy to clean later
