Abstract

The invention discloses a method for carrying out one-side copper plating on a wide stainless steel band and an electroplating bath. The method comprises the following steps: carrying out oil removal and activation on the pre-plating surface of the stainless steel band of a substrate; carrying out nickel pre-plating and general nickel plating on the activated pre-plating surface of the stainless steel band of the substrate, and carrying out copper plating in an alkaline cyanide-free plating solution; passivating and drying the copper-plated stainless steel band. The improved electroplating bath is adopted in the copper plating process, at least two transmission rotary rollers are hermetically mounted on two groove walls at a transmission inlet and a transmission outlet of the electroplating bath respectively, and the electroplating bath can be used for guaranteeing the liquid level of the bath and preventing a plated layer of the stainless steel band from being scratched and is especially suitable for continuous one-side copper plating of the wide band-shaped stainless steel band. The method is safe, environment-friendly, low in cost and capable of carrying out high-speed one-side copper plating on the wide stainless steel band; the one-side plated layer of the stainless steel band, prepared by the method, is uniform, bright and compact in surface, good in corrosion resistance, high in electric conductivity and excellent in stamping resistance, meets the requirements of electronics and military industry, and can be industrially produced.

Description

technical field

[0001] The invention relates to a single-sided copper plating method for a wide stainless steel strip and an electroplating tank, belonging to the field of metal electroplating. Background technique

[0002] Single-sided copper-clad stainless steel materials will be widely used in electronic information materials, decorative materials and military materials industries due to their characteristics of brightness, high hardness, strong corrosion resistance, and good conductivity of the copper layer. A lot of research has been done on the copper plating process both at home and abroad. At present, the main copper plating methods are: cyanide copper plating, pyrophosphate copper plating, sulfate copper plating, ethylenediamine copper plating, fluoboric acid copper plating, citric acid-tartaric acid copper plating, HEDP copper plating and sulfamic acid copper plating system etc. Cyanide copper plating has fine crystallization, good bonding force, plating solution...
