A kind of long-acting wire drawing fluid for cemented carbide

Abstract

The invention relates to a drawing fluid, in particular to a long-acting drawing fluid for hard alloys. The drawing fluid is prepared by raw materials in parts by weight as follows: 25-28 parts of naphthenic oil, 4-5 parts of tetrabutyl titanate, 15-20 parts of pentaerythritol oleate, 1-2 parts of sodium gluconate, 10-12 parts of polyoxyethylene glycol (6000) bisstearate, 5-6 parts of sodium alcohol ether sulphate, 1-2 parts of dibromo dimethylhydantoin, 1-2 parts of phytic acid, 4-5 parts of auxiliaries and 800-1,000 parts of deionized water. According to the drawing fluid, naphthenic oil and pentaerythritol oleate are mixed to serve as base oil, raw materials such as phytic acid, sodium gluconate and the like are taken as chelation, corrosion inhibition, rust resisting and antibacterial additives, alloy wire surfaces are effectively protected, the cleaning capacity is improved, and the storage life of the drawing fluid is prolonged. The drawing fluid is resistant to extreme pressure and abrasion, the friction force of the hard alloys in the drawing process can be reduced, the loss of molds and wires is reduced, and the drawing efficiency is improved.

Description

technical field [0001] The invention relates to a wire drawing liquid, in particular to a long-acting wire drawing liquid for cemented carbide 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
