Copper wire drawing annealing liquid and using method thereof

Abstract

The invention relates to the technical field of copper wire drawing annealing, in particular to copper wire drawing annealing liquid and a using method thereof. The copper wire drawing annealing liquid is prepared from, by weight, 40-60 parts of copper antioxidant, 1-5 parts of solubilizer, 3-5 parts of boric acid, 5-10 parts of organic alcohol amine, 5-10 parts of antirust agent, 5-20 parts of self-emulsifying ester, 0.01-0.1 part of defoaming agent, 5-10 parts of bactericide and the balance water, and the total weight part of the copper wire drawing annealing liquid is 100. Compared with a traditional AB double-component wire drawing annealing solution, the copper wire drawing annealing liquid is more convenient to use, long in anti-oxidation time, good in lubricating property on an annealing cone pulley and not prone to abrasion, the single-component wire drawing annealing solution is high in antibacterial property, the service life of the single-component wire drawing annealing solution can exceed 6 months even under the concentration of 0.5%, wastewater discharge and treatment cost of the traditional double-component wire drawing annealing solution are reduced, the single-component annealing liquid is convenient and fast to use, errors are not prone to occurring, the oxidation resistance of the copper antioxidant and the lubricity of the wire drawing liquid are combined into a whole to the maximum extent, and management and control are convenient.

Description

technical field

[0001] The invention relates to the technical field of copper wire drawing annealing, in particular to a copper wire drawing annealing liquid and a use method thereof. Background technique

[0002] Copper wire drawing refers to the processing method in which the copper wire busbar wire is forced through the mold under mechanical action to obtain the required cross-sectional shape and size. After the copper busbar is drawn and formed by several combined dies, the diameter of the wire is reduced proportionally to the required size. At the same time, in order to eliminate the internal stress of the wire during the drawing process, it is often necessary to anneal the copper wire.

[0003] Copper wire annealing is divided into two processes: stuffy tank annealing (no need for annealing liquid) and online annealing (requiring annealing liquid). In the past, the annealing solution used in the factory was generally AB two-component. The drawing solution and copper a...
