Abstract

The invention provides a preparation method of a chemical nickel-plating solution. The preparation method includes the steps of coursing, sensitizing, activating and nickel plating. The preparation method is simple in process. The chemical nickel-plating solution which is prepared through the method and is high in stability and long in service life has relatively stable chemical nickel plating performance and is long in service life, and meanwhile the crystallization of a product obtained through chemical nickel plating is more delicate.

Description

technical field [0001] The invention relates to a preparation method of an electroless nickel plating solution with high stability and long service life. Background technique [0002] Electroless nickel plating is one of the effective processes for the metallization of non-metallic surfaces at present. The electroless nickel plating process can obtain a uniform and bright nickel plating layer. The traditional electroless nickel plating process has always had the problem of low solution stability. After a certain period of use, it is easy to cause the entire nickel plating solution to be scrapped. The process of nickel plating wastewater. Therefore, the development of an electroless nickel plating solution with high stability and long service life is of great significance for reducing the impact of wastewater treatment on the environment and improving the economic benefits of enterprises. Contents of the invention [0003] The invention aims to provide a preparation metho...
