A kind of antirust agent for electrical copper flexible stranded wire

Abstract

The invention provides an antirust agent for electrical copper soft stranded wire, the antirust agent includes the following chemical components in weight percentage: scale and corrosion inhibitor: 15-30%, benzotriazole: 12-20%, Sodium molybdate: 1~5%, zinc salt: 2~6%, ethanolamine: 15~30%, ethanol: 5~10%, dodecenylsuccinic acid: 4~8%, phytic acid ester: 3~6%, sodium citrate: 0.5~2%, the rest is water. The antirust agent is non-toxic and environmentally friendly. After the copper wire is annealed and cooled, it can form a uniform, dense and hard-to-fall protective film on the surface of the copper wire, so that the copper wire has good anti-discoloration and anti-oxidation capabilities, and is effective Improve the shelf life and service life of copper wire, and reduce production costs.

Description

technical field [0001] The invention belongs to the field of wire protection for electrical equipment and electronic components, and in particular relates to an antioxidant for ultra-fine electrical copper braided wires. Background technique [0002] In today's metal 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, the proportion of which is occupied year by year rising trend.

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 metal, coupled with the high processing cost and labor cost, 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 to solve
