Totally-synthetic high-speed copper drawing fluid

Abstract

The invention relates to a totally-synthetic high-speed copper drawing fluid, which comprises, by mass percentage, 5-10% of triethanolamine, 5-9% of amide caproic acid triethanolamine salt, 8-15% of polyethylene glycol, 0.5-3.0% of special amine, 0.5-2.0% of disodium EDTA, 0.1-0.5% of T706, 3.0-6.0% of diglycol, 3.0-6.0% of polyether 1740, 1.5-4.0% of sebacic acid, 6.0-12.0% of diethanolamine, 0.5-1.5% of an MBM bactericide, and 0.03-0.15% of an antifoaming agent, with the balance being water. The fluid gives off faint smell, and is excellent in lubricity, cleaning ability and copper corrosioninhibition performance. During high-speed drawing of copper wires, the liquid protects a die and cone pulley from being attached with copper powder and copper sludge, so that the service life of thedie and cone pulley is greatly prolonged.

Description

technical field [0001] The invention belongs to the field of lubricating oil, and relates to a copper wire drawing liquid, in particular to a fully synthetic high-speed 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 [0003] It is getting higher and higher (some are drawn by multiple heads), and the requirements for the surface quality of copper wires are also greatly improved, and the requirements for environmental protection are also 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 imp...

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
