Copper wire drawing lubricating fluid and preparation method thereof

Abstract

The invention discloses a copper wire drawing lubricating fluid and a preparation method thereof. The lubricating fluid and the preparation method are characterized in that: the lubricating fluid is prepared from following raw materials by weight: 15-25 parts of palm oil, 2-3 parts of sodium petroleum sulfonate, 30-35 parts of polyethylene glycol, 1-2 parts of sulfurized calcium alkyl phenolate, 1-2 parts of a sodium naphthenate, 2-3 parts of a water soluble phosphate ester, 1-2 parts of sodium benzoate, 2-3 parts of triethanolamine oleate, 0.2-0.4 part of diamond nanoparticles, 10-14 parts of an antiwear agent and 1000 parts of water; nano aluminium nitride powder is added into the antiwear agent, thus promoting heat dissipation, enhancing cooling effects, enhancing film-forming property and prolonging the service lifetime; the service cycle of the lubricating fluid is long; and copper wires after wire drawing processes have significant characteristics of shining surfaces, capability of being stored for a long time, difficult surface oxidation, simple manufacturing technology, low technical requirements, and the like.

Description

technical field [0001] The invention relates to the field of metal processing, in particular to a copper wire drawing lubricant and a preparation method thereof. Background technique [0002] The wire drawing process is a metal processing process. In metal pressure processing. Under the action of external force, 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 tool that makes it change shape and size is called a wire drawing die. [0003] At present, many manufacturers of wire and cable use soapy water-based drawing oil when drawing wire cores, mainly using the alkalinity of soapy water to clean the wire cores, and also have a lubricating function. But it has the following disadvantages: because the lubricating effect of soapy water is not strong, it is easy to damage the product and the mold...

AI Technical Summary

Problems solved by technology

But it has the following disadvantages: due to the weak lubricating effect of soapy water, it is easy to damage the product and the mold; the alkalinity of soapy water is relatively heavy, which makes the drawn product easy to oxidize and deteriorate, which affects the quality of the finished product

However, foreign wire drawing oil products are expensive, which greatly increases the production cost.
