Abstract

The invention discloses a nickel ecological copper plating water-based technological material. The nickel ecological copper plating water-based technological material is composed of the following rawmaterials of, by mass, 0.1-3% of an emulsifying agent, 0.3-2% of a levelling agent, 5-15% of neutral salt, 11-15% of nitrate, 3-13% of organic salt and the balance water. The nickel ecological copperplating water-based technological material provided by the invention is reasonable in formula, a direct-current power supply does not need to be additionally arranged, a heating source is not needed,a nickel-plated piece serves as the cathode, different electric potentials exist in the state of the nickel-plated piece, and thus through the mode of ion exchanging, copper ions on a lining copper roller dissociate into the nickel ecological copper plating water-based technological material and are combined with the nickel-plated piece, so that a compact copper-plated layer is formed on the surface of the nickel-plated piece; the copper plating effect is good, the thickness of the copper-plated layer is even, the comprehensive property of a product is effectively promoted, and the service life is prolonged; and additionally, a copper plating method is concise in technological step, easy to achieve, high in copper plating efficiency, low in cost and capable of saving energy, protecting theenvironment and facilitating wide application and popularization.

Description

technical field [0001] The invention relates to the technical field of copper plating of nickel parts, in particular to a nickel ecological copper plating water-based process material and a copper plating method thereof. Background technique [0002] There are three copper plating processes currently used in production, namely cyanide copper plating, pyrophosphate copper plating and sulfate copper plating. [0003] Cyanide copper plating is the earliest and most widely used copper plating process. The plating solution is mainly composed of copper cyanide complex and a certain amount of free cyanide, which is strongly alkaline. Because cyanide has a strong activation and complexing ability, the first feature of this electroplating method is that the solution has a certain degreasing and activation ability. Secondly, because this plating solution uses cyanide with strong complexing ability, the complex ion is not easy to discharge, so the cathodic polarization of the bath is...
