Abstract

The invention is suitable for the technical field of electroplating, and provides a low-concentration and long-acting pearl nickel electroplating additive, electroplating solution and electroplating method.The low-concentration and long-acting pearl nickel electroplating additive comprises a bath building agent and a coarse and fine sand agent and further comprises an auxiliary agent, the bath building agent comprises 80-120 g/L of saccharin sodium salt and 5-40 g/L of sodium allysulfonate, and the auxiliary agent comprises 15-30 g/L of hydrophilic natural colloid. The coarse and fine sand agent comprises 0.1-0.6 g/L of a succinate surfactant and 15-25 g/L of a polyoxyethylene alcohol surfactant. The nickel sulfate-based sand raising agent has the beneficial effects that the addition of the ultralow-concentration nickel sulfate can play a role in assisting the sand raising, the stability and the long-acting effect of the sand agent can be maintained by the aid of the auxiliary agent, and the coarse and fine sand agent and the bath building agent are good in auxiliary synergistic cooperation.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to a low-concentration, long-acting pearl nickel electroplating additive, an 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...
