Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems that the copper layer of the copper-clad steel wire produced in the traditional process is not well bonded to the substrate, and a large amount of acid mist and waste liquid are generated in the production process. Copper-clad steel wire matrix pretreatment production process with complete layer treatment, bright steel wire surface, good anti-oxidation effect and good bonding force between the treated steel wire and the copper layer in the subsequent electroplating process

Embodiment Construction

[0015] The present invention is further described below.

[0016] A production process for the pretreatment of a copper-clad steel wire substrate, comprising the following steps in sequence.

[0017] (1) Peeling: Oxidation of the steel wire under natural conditions will generate an excessively thick oxide layer. Because the oxide layer is brittle and has low extensibility, it needs to be peeled off. The steel wire is derusted and peeled by machinery to remove the oxide layer on the surface of the steel wire. , Specifically, the steel wire is processed into a steel wire matrix with a diameter of 6.5mm or 5.5mm.

[0018] (2) Steel wire brush to remove rust, after mechanical shelling, use a steel wire brush to wipe off the residual oxide layer on the surface of the steel wire substrate.

[0019] (3) Pickling, pickling with a hydrochloric acid solution with a volume ratio of 50%, further removing the oxide layer remaining on the surface of the steel wire substrate due to incomple...

Abstract

The invention, relating to a production technology of copper-clad steel, particularly discloses a production technology of preprocessing a copper-clad steel wire matrix, successively comprising the following steps: husking, derusting with a wire brush, pickling, washing, boronizing, drawing, secondary washing, drying and spooling, and ammonia decomposition tempering. The technology has the following advantages: little pollution in the production process, complete treatment of the surface oxidation layer of the steel wire, bright surface of the steel wire, good anti-oxidation effect, and good binding force between the processed steel wire and the copper layer in the subsequent electroplating process.

Description

technical field [0001] The invention relates to a production process of copper-clad steel, in particular to a production process of pre-treatment of copper-clad steel wire matrix. Background technique [0002] Copper-clad steel wire is a new type of composite wire made of a steel core with a layer of copper on its surface and then drawn. This product not only has the strength and toughness of steel, but also has the good conductivity and corrosion resistance of copper. It has become an updated product of traditional pure copper single wire and is widely used in communications, transportation, metallurgy, electronic instruments, machinery, power transmission etc. However, copper-clad steel wire has always had a common industry problem of poor bonding force, which has not been effectively solved for a long time. After analysis and research, it is found that the pre-treatment of copper-clad steel substrate-steel wire has a great influence on the bonding force. [0003] The tr...
