Problems solved by technology

The existing nickel-plating brighteners with better performance are the fourth-generation brighteners, but if only softeners, secondary brighteners or auxiliary brighteners are used, the porosity of the coating is high, the brightness is poor, and the dispersion ability of the plating solution is low. , Poor plating ability

Abstract

A nickel plating brightener and an electroplating method are disclosed. The nickel plating brightener comprises 100-120 g / L of saccharin sodium, 40-60 g / L of p-toluenesulfonamide, 45-60 g / L of pyridinium hydroxy propyl sulfobetaine, 30-40 g / L of propynol ethoxylate, 5-10 g / L of sodium propynesulfonate, and 0.5-2 g / L of sodium vinylsulfonate. The nickel plating brightener combines a primary brightener, a secondary brightener and an auxiliary brightener which are prepared from intermediates, and is capable of reducing porosity of platings, improving brightness of the platings, and enhancing dispersibility and throwing power of a plating solution.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a nickel plating brightener and an electroplating method. Background technique [0002] Nickel electroplating is one of the most important plating types in the electroplating industry. Nickel coating has the advantages of high hardness, wear resistance, corrosion resistance and good decoration, and has been widely used in aviation, automobile, material engineering and other fields. In order to improve the performance of the coating and obtain a high-quality nickel coating, electroplating additives are often added to the plating solution. Although the concentration of additives in the plating solution is very low, it has a great influence on the quality of the coating. To some extent, the quality of the nickel coating depends on the quality of the additives. [0003] After decades of development, nickel plating brighteners have gone through four stages: the first...
