Copper-clad aluminum conductor production process

Abstract

The invention discloses a copper-clad aluminum conductor production process comprising the following processing steps of: 1, deoiling the aluminum conductor by soaking the aluminum conductor in a chemical solvent; 2, cleaning; 3, pickling the aluminum conductor in a pickling solution for activating; 4, pre-nickeling the aluminum conductor in a solution containing 5-30 g / L of nickel chlorite, 50-150 g / L of nickel aminosulfonate, 20-100 g / L of boric acid and additives; 5, cleaning; 6, coppering the pre-nickeled aluminum conductor in a solution containing 30-50 g / L of copper nitrate, hydroxy ethylidene diphosphate and additives at 25-40 DEG C and with current density of 2-5 A / dm<2>; 7, cleaning the aluminum conductor through clear water at 30-40 DEG C; and 8, winding and packaging the aluminum conductor. The copper-clad aluminum conductor production process disclosed by the invention is reasonable in process, the aluminum conductor is nickeled and coppered by the environmentally-friendly and non-pollution plating solutions, the plating combination strength of produced copper-clad aluminum conductors with various diameters is high, and the subsequent drawing quality of the conductors is good.

Description

technical field [0001] The invention belongs to the field of electroplating technology, and in particular relates to a copper-clad aluminum wire production process. Background technique [0002] Copper wire has good conductivity and shielding, which is a high-quality material for wires and cables, but it is expensive and costly. Aluminum wire is cheap and light in weight and has high economic efficiency. The current copper-clad aluminum wire adopts the coating process, which cannot be fully combined. , Subsequent drawing will break away or there will be gaps affecting product quality.
