Pearl nickel electroplating additive, pearl nickel electroplating solution and electroplating method

Abstract

The invention provides a pearl nickel electroplating additive, a pearl nickel electroplating solution and an electroplating method. The pearl nickel electroplating additive comprises a brightening agent and a frosting agent, wherein the brightening agent comprises saccharin sodium and sodium allylsulfonate, and the frosting agent comprises succinate salt type surfactants and carboxylate type surfactants. The pearl nickel electroplating solution comprises a basic electronickelling solution and the pearl nickel electroplating additive. The electroplating method comprises the following steps: preparingthe pearl nickel electroplating solution; regulating the pH value and the temperature of the electroplating solution, and then performing electronickelling by using a preplating piece as a cathode. The pearl nickel electroplating additive disclosed by the invention is reasonable in formula, the dispersibility of the basic electronickelling solution is good, the frosting agent and the brightening agent mutually cooperate and act to enable the surface of the preplating piece to be uniformly frostedin a pearl nickel electroplating process, the frosting effect is good, the internal stress is ecreased, and the obtained pearl nickel plate is glossy, good in brightness and gentle.

Description

technical field

[0001] The invention relates to the technical field of pearl nickel, in particular to an additive for pearl nickel electroplating, a pearl nickel electroplating solution and an electroplating method. Background technique

[0002] Pearl nickel, also known as satin nickel, satin nickel, pitted nickel, is a coating with gorgeous appearance, fine and soft color, low internal stress, good corrosion resistance, and is a good protective decorative coating. The pearl nickel electroplating process first appeared in the 1950s and developed rapidly after the 1990s. Pearl nickel can be directly used as a protective decorative coating, and other metals, such as chromium, gold, silver, etc., can also be plated on pearl nickel, which has a stronger protective decorative effect. At present, pearl nickel coating has been widely used in automobile decoration, electronic products, daily hardware, stationery and other industries.

[0003] At present, there are mainly two kinds...
