Abstract

The invention discloses bright dispersant for imitation gold plating and a preparation method thereof and belongs to the technical field of surface plating treatment for metal or nonmetal articles. The bright dispersant comprises butynediol ethoxylate, nicotinic acid, potassium hydroxide, saccharin, and sodium allylsulfonate, all these components are nontoxic, phosphorus (phosphine) free and ammonia free, and are nontoxic and harmless to the environment and human; in addition, the bright dispersant has good brightness and dispersibility, provides a wide golden current density range for a coating of imitation gold, and provides uniform gold appearance for the imitation gold coating; additionally, the bright dispersant is more applicable to imitation gold plating of complex workpieces and long-hole workpieces.

Description

technical field [0001] The invention relates to the technical field of surface electroplating treatment of metal or non-metal products, in particular to a bright dispersant for imitation gold electroplating and a preparation method thereof. Background technique [0002] Imitation gold electroplating process is an important electroplating process technology in the field of metal or non-metal surface treatment technology. It can be divided into electroplating Cu-Zn binary alloy and adding a small amount of tin or nickel elements to form ternary, Quaternary alloy coating and other types. It can plate a layer of 12-24K gold on the surface of metal and non-metal, but it is actually an alloy coating of non-gold elements. [0003] Because of its excellent performance and metal-like color, imitation gold coating is widely used in hardware, furniture, lighting, bags, clocks, audio, building materials, indoor and outdoor advertising, signboards, jewelry, etc., and has an irreplaceabl...
