High-corrosion-resistance bright electronickelling plating solution as well as preparation method and use method thereof

Abstract

The invention discloses a high-corrosion-resistance bright electronickelling plating solution as well as a preparation method and a use method thereof, belongs to the technical field of electronickelling, and solves the problem of poor bright electronickelling corrosion resistance of a plating solution taking nickel sulfate as a main component in the prior art. The plating solution is prepared from 200 g / L-300 g / L of nickel sulfate, 30 g / L-50 g / L of nickel chloride, 30 g / L-50 g / L of boric acid, 0.006 g / L-0.10 g / L of sodium dodecyl benzene sulfonate, 5 mg / L-70 mg / L of MOSS, and 0.01 g / L-0.2 g / Lof sodium benzenesulfinate, and water serves as a solvent. The preparation method comprises the following steps: weighing the components according to the concentrations of the components in the high-corrosion-resistance bright electronickelling plating solution solution; and mixing the components to obtain the high-corrosion-resistance bright electronickelling plating solution. The use method comprises the following steps: carrying out pretreatment on a base material; heating the high-corrosion-resistance bright electronickelling plating solution; putting the base material into the high-corrosion-resistance bright electroplating nickel plating solution for nickel plating; and obtaining the base material with a nickel plating layer. According to the plating solution as well as the preparation method and the use method thereof, the brightness and the corrosion resistance of the nickel plating layer can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of nickel electroplating, and in particular relates to a highly corrosion-resistant bright nickel electroplating solution and a preparation method and application method thereof. Background technique [0002] Nickel electroplating has been widely used for a long time because of its simple electroplating process, low cost and good protection performance. At present, nickel plating mostly adopts a double-layer or three-layer nickel plating system. The bright nickel layer and the semi-bright nickel layer in the double-layer nickel plating layer will form a galvanic corrosion system. Corrosion, therefore, double-layer nickel coating will have better corrosion resistance. For the single-layer bright nickel plating layer, adding a variety of brighteners to the plating solution will increase the sulfur content in the plating layer and deteriorate the corrosion resistance.
