Cleaning agent for electrical copper braided wire

Abstract

The invention provides a cleaning agent for electrical copper braided wire. The cleaning agent includes the following chemical components in weight percentage: scale and corrosion inhibitor: 20-25%, sodium tripolyphosphate: 1-5%, sodium citrate: 0.5~3%, trichloroethane: 2~5%, polyacrylic acid: 10~20%, phosphoric acid: 15~30%, fatty acid glyceride: 10~18%, penetrant 5~12%, emulsifier: 3 ~5%, defoamer: 2~6%, the rest is water. The cleaning agent is non-toxic and environmentally friendly, and can effectively clean and remove the copper rust produced on the surface of the oxidized electrical copper braided wire, and after cleaning, a layer of uniform, dense and hard-to-fall protective film can be formed on the surface of the electrical copper braided wire. The electrical copper braided wire has good anti-discoloration ability and anti-oxidation ability, effectively improves the shelf life and service life of the electrical copper braided wire, and reduces 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 a cleaning agent for 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

[0004] Copper is originally a relatively precious metal, coupled with the current expensive processing costs and labor costs, many manufacturers are worried about a pile of oxidized products. How to deal with oxidized copper products has become an urgent problem for many manufacturers.
