A kind of drawing liquid for rapid drawing of copper wire

Abstract

The invention relates to a drawing fluid, in particular to a drawing fluid for rapidly drawing a copper wire. The drawing fluid is prepared by raw materials in parts by weight as follows: 25-30 parts of perfluoropolyether oil, 15-18 parts of trihydroxymethylpropyl trioleate, 10-12 parts of polyglycerol fatty acid ester, 1-2 parts of sodium monofluorophosphate, 4-5 parts of microcrystalline cellulose, 2-3 parts of zinc dialkyl dithiophosphate, 2-4 parts of polyethylene glycol, 1-2 parts of Schiff base, 2-3 parts of polydimethylsiloxane, 4-5 parts of an auxiliary and 800-1,000 parts of deionized water. According to the drawing fluid, perfluoropolyether oil and trihydroxymethylpropyl trioleate which still have excellent lubricating property under high-temperature and high-speed drawing are taken as base oil and matched with additives such as microcrystalline cellulose, sodium monofluorophosphate and the like, so that the prepared drawing fluid can effectively improve the wiredrawing efficiency and better protect wires and molds, the wire surfaces are smooth and complete, oxidizing blackening is avoided, less wire breaking is caused, and rapid and efficient drawing requirements can be met..

Description

technical field [0001] The invention relates to a wire drawing liquid, in particular to a wire drawing liquid for rapid drawing of copper wires and a preparation process thereof. Background technique [0002] The wire drawing process is a metal processing process, which refers to the technical processing method in which the metal wire is forcibly passed through the mold under pressure to obtain the required cross-sectional area shape and size, and the wire drawing liquid is an indispensable auxiliary agent in the wire drawing process. Its main function is to lubricate in the wire drawing process of various copper wires and aluminum wires, such as medium drawing, small drawing, micro drawing, etc., and protect the wires and molds to achieve a good drawing effect. The quality of the liquid directly affects the wire drawing effect. The wire drawing liquid with excellent performance can protect the mold very well, reduce the phenomenon of wire breakage and mold wear, and has the...

[0002] The wire drawing process is a metal processing process, which refers to the technical processing method in which the metal wire is forcibly passed through the mold under pressure to obtain the required cross-sectional area shape and size, and the wire drawing liquid is an indispensable auxiliary agent in the wire drawing process. Its main function is to lubricate in the wire drawing process of various copper wires and aluminum wires, such as medium drawing, small drawing, micro drawing, etc., and protect the wires and molds to achieve a good drawing effect. The quality of the liquid directly affects the wire drawing effect. The wire drawing liquid with excellent performance can protect the mold very well, reduce the phenomenon of wire breakage and mold wear, and has the functions of rust prevention, cooling and cleaning. On the contrary, it will seriously affect the drawing quality; As the wire drawing process is widely used, the market has higher and higher requirements for the quality of the wire drawing liquid. The existing wire drawing liquids mainly have problems such as poor emulsion stability, corrosion of metal wires, high energy consumption, and difficulty in cleaning, etc., which restrict wire drawing and drawing. To improve the quality, it is urgent to improve its formula and process to make it more efficient and environmentally friendly
