Copper wire braided wire passivation agent

Abstract

The present invention provides a copper wire braided wire passivation agent including the following chemical components by weight 15-25% of a phosphate salt, 22-30% of a molybdate salt, and 10-20% of phosphate, 2-20% of a titanium salt, 3-10% of fluotitanic acid, 1-10% of citric acid, 10-20% of phytic acid and balance of water. The copper wire braided wire passivation agent is non-toxic and environmentally-friendly, after copper wire annealing cooling, a layer of uniform, dense and hard-to-fall off protective film is produced on the copper wire surface, so that the copper wire has good capability of preventing discoloration and oxidation resistance, storage time limit and service life of the copper wire braided wire obtained by copper wire braiding can be effectively improved, and the production cost can be 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 passivator 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 surface...

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.
