Copper wire drawing liquid

Abstract

The invention relates to a copper wire drawing liquid, which comprises the following raw materials by weight: 3-8% of pentaerythritol isooctanoate, 1-5% of an extreme pressure agent, 0.1-0.8% of a water-soluble copper corrosion inhibitor, 1.0-5.0% of ammonium borate, 0.2-1.5% of phosphate, 4-12% of fatty alcohol polyoxyethylene ether, 5-15% of polyether, 0.5-2.5% of diethylene glycol, 0.5-1.5% ofa sterilization agent MBM, and the balance of base oil. According to the present invention, the copper wire drawing liquid can meet the rapid copper wire drawing requirement, is the micro-emulsification liquid containing a small amount of mineral oil, uses the synthetic polyol fatty acid ester as the oily agent, uses the water-soluble phosphorus-containing compound as the extreme pressure agent, uses the polyether-based nonionic surfactant as the main emulsifier, has effects of good lubrication, good cooling and good cleaning, does not easily generate copper soap, has characteristics of long service life and good oxidation resistance, and can completely meet the rapid copper wire drawing requirement.

Description

technical field [0001] The invention belongs to the field of chemical products, in particular to a copper wire drawing liquid. Background technique [0002] The copper wires used in wires and cables, enameled wires, etc. are all drawn by water tank wire drawing machines. With the rapid development of modern industry, the drawing speed is getting higher and higher (some are drawn by multiple heads), and the requirements for the surface quality of copper wires are also greatly increased. At the same time, environmental protection requirements are becoming more and more serious. In the copper wire drawing process of my country's cable industry, copper material and enameled wire industry, there are generally phenomena such as oxidative discoloration and blackening, which are more serious in spring and summer. With the popularity of existing high-speed machines, the drawing speed has been greatly improved, and the contradictions have become more and more prominent. All these pr...

Problems solved by technology

The main disadvantage of saponified oil is that in the case of copper wire drawing, a tribochemical reaction occurs to form copper soap. The fatty acid copper soap is hydrophobic and is easy to deposit on the metal surface, causing broken wires and dirtying the copper wire. At the same time, the lubricant consumption is greatly increased. , causing demulsification in severe cases and shortening the service life

Animal and vegetable oils have good lubricity, but due to the existence of a large number of double bonds, they are easy to oxidize and deteriorate, and black pollutants are easily carbonized during the drawing process. Sulfonated castor oil is easy to corrode copper wire due to its sulfur content, making the copper wire The oxidation resistance is greatly reduced, and the surface quality is not good
