Washing agent for electrical copper braided wire

Abstract

The invention provides a washing agent for electrical copper braided wire. The washing agent comprises the following chemical components in percentage by weight: 20 to 25% of scale and corrosion inhibitor, 1 to 5% of sodium tripolyphosphate, 0.5 to 3% of sodium citrate, 2 to 5% of trichloroethane, 10 to 20% of polyacrylic acid, 15 to 30% of phosphoric acid, 10 to 18% of fatty acid glyceride, 5 to 12% of osmotic agent, 3 to 5% of emulsifier, 2 to 6% of antifoaming agent, and the balance being water. The washing agent is nontoxic and environment-friendly, can effectively wash off the copper scales on the surface of electrical copper braided wires after oxidation, and can form a protective film on the surface of electrical copper braided wires after washing, because the film is uniform and compact and is hard to peel off, the electrical copper braided wire has a very good performance on preventing fading and oxidation therefore, the preservation time and service life of electrical copper braided wire are both prolonged, 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 cleaning agent for electrical copper braided wires.

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.
