Protective agent for braided copper wire

Abstract

The invention provides a protective agent for braided copper wires. The protective agent includes the following chemical components in weight percent: polyacrylate emulsion: 15-20%, ethanol: 15-30%, benzotriazole: 12-20%. 20%, rare earth salt: 15~25%, sodium molybdate: 1~5%, zinc salt: 2~6%, fatty acid glyceride: 0.5~3%, propylene glycol methyl ether acetate: 4~8%, the rest is water. The protective agent is non-toxic and environmentally friendly. After the copper wire is annealed and cooled, a uniform, dense and hard-to-fall protective film can be formed on the surface of the copper wire, so that the copper wire has good anti-discoloration and anti-oxidation capabilities, effectively improving The shelf life and service life of the copper wire are improved, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of wire protection for electrical equipment and electronic components, and in particular relates to a protective agent for braided copper wires. Background technique [0002] In today's copper wire processing industry, the market share of copper processing is increasing, especially in electroplating, spraying, cables, circuit boards, CNC, molds, stamping hardware, powder metallurgy and other industries. It is showing an upward trend year by year. [0003] With the continuous growth of the industry, the quality requirements of the products are also continuously improved. However, in the process of copper processing, the problem of oxidation of copper and copper alloys after processing and cleaning has always been a problem in the industry, especially for electrical equipment, Copper wires, copper braided wires and electrical copper flexible stranded wires connected to electronic components are easily oxidized on the s...

Problems solved by technology

[0003] With the continuous growth of the industry, the quality requirements of the products are also continuously improved. However, in the process of copper processing, the problem of oxidation of copper and copper alloys after processing and cleaning has always been a problem in the industry, especially for electrical equipment, Copper wires, copper braided wires and electrical copper flexible stranded wires connected to electronic components are easily oxidized on the surface after being made into copper wires. It will form a patina, that is, basic copper carbonate, which is green; or it may be oxidized to cuprous oxide, which is brick red, and oxidized slag will form after a few days

Copper is originally a relatively expensive copper wire, coupled with the current expensive processing costs and labor costs, many manufacturers are worried about a pile of oxidized products. How to deal with the delivery of oxidized products has become an urgent problem for many manufacturers.
