Abstract

The invention relates to a drawing fluid, in particular to a drawing fluid for high-speed drawing of a superfine copper wire. The drawing fluid is prepared by raw materials in parts by weight as follows: 26-30 parts of polymethylphenyl siloxane fluid, 4-5 parts of tripolyglycerol monostearates, 20-22 parts of poly alkylene glycol, 2-4 parts of sulfurized isobutylene, 1-2 parts of sodium metaborate, 2-3 parts of methyl 4-hydroxybenzoate, 1-2 parts of a bamboo leaf antioxidant, 4-6 parts of alkylphenol ethoxylates, 3-5 parts of isobutyltriethoxysilane, 4-5 parts of auxiliaries and 800-1,000 parts of deionized water. The drawing fluid takes a mixture of polymethylphenyl siloxane fluid and poly alkylene glycol as base oil, and additives such as sulfurized isobutylene, sodium metaborate, the bamboo leaf antioxidant and the like are supplemented, so that extreme pressure wear resistance, oxidation resistance and antibacterial property of the emulsion are improved. The prepared drawing fluid still has good lubricating property and is not easy to scale after repeated use, and the problem that fine copper wires are easy to break is thoroughly solved.

Description

A kind of ultra-fine copper cash high-speed wire-drawing wire drawing liquid

Technical field

The present invention relates to a kind of wire drawing liquid, be specifically related to a kind of ultra-fine copper cash high-speed wire-drawing wire drawing liquid and preparation technology thereof.

Background technology

Drawing process is a kind of metal working process, refer to that metal wire passes through mould under pressure by force, obtain the technology working method of desired sectional area shape and size, wire drawing liquid is requisite auxiliary in drawing process, its main effect is at multiple copper wire, in the multiple wire rod of aluminium wire, draw, little drawing, finely the wire drawing such as draw, lubricate in bracing wire technological process, have protection wire rod concurrently, mould, reach good wire-drawing effect, the quality of wire drawing liquid directly has influence on wire-drawing effect, the wire drawing liquid of excellent property can well be protected mould, reduce wire rod broken end, die wear phenomenon, have concurrently antirust, cooling, the effects such as cleaning, otherwise, can have a strong impact on wire drawing quality, along with the application of drawing process is extensive gradually, market is more and more higher to the quality demand of wire drawing liquid, existing wire drawing liquid mainly exists that stability of emulsion is poor, corroding metal wire rod, energy consumption are high, the problem such as easy cleaning not, restricting wire drawing, drawing quality, be badly in need of improving its composition and engineering, make its more high-efficiency environment friendly.

Summary of the invention

The object of the invention is to, a kind of ultra-fine copper cash high-speed wire-drawing wire drawing liquid is provided, situation about easily breaking in drawing process to alleviate ultra-fine copper cash, to achieve these goals, the technical solution used in the present invention is as follows:
