Problems solved by technology

[0002] The Chinese patent application titled "A Gold Electroplating Method for Flowers" (Notice No. 1339620) discloses a method of using cyanide to perform pure gold electroplating on flowers. Because cyanide is used in the electroplating technology, it is easy to pollute the environment. Second, the cost of pure gold plating is higher

Embodiment Construction

[0008] The best way to realize the present invention is as follows: first, wash the flower surface with thick soapy water at 35°C for 35 minutes, take it out and rinse it with clear water, rub it with silk to make its surface rough, and soak it in alcohol for 8 minutes; Then use the prepared coarsening aqueous solution for 3 minutes roughening treatment at 25°C; use the prepared sensitizing aqueous solution for 4 minutes sensitization treatment at 23°C; use the prepared activation aqueous solution for 3 minutes activation treatment at 23°C; The prepared reducing solution was reduced for 3 minutes; the prepared electroless copper plating solution was used for 18 minutes at 35°C for 18 minutes; the prepared bright copper plating solution was used for 18 minutes at 25°C, 3A / dm 2 Under the conditions of cathodic current density, carry out bright acidic copper plating for 8 minutes; use the prepared cyanide-free imitation gold plating solution at 33 ℃, Ph value 8.5-8.8, cathodic cur...

Abstract

A non-cyanogen golden electroplating on the surface of flower, tree leaf, or beetle, includes such steps as preparing golden electroplating liquid from copper sulfate, zinc sulfate, stannous chloride, potassium pyrophosphate, potassium sodium tartrate, potassium citrate and aminotriacetic acid, washing, roughening, sensitizing, activating, reducing, chemically plating copper, polishing, electroplating golden layer, passivating and coating protective film.

Description

technical field [0001] The invention relates to the technical field of cyanide-free electroplating imitation gold, specifically, relates to a method for cyanide-free electroplating imitation gold on the surface of flowers, and is also suitable for leaves or beetles to perform cyanide-free electroplating imitation gold. Background technique [0002] The Chinese patent application titled "A Gold Electroplating Method for Flowers" (Notice No. 1339620) discloses a method of using cyanide to perform pure gold electroplating on flowers. Because cyanide is used in the electroplating technology, it is easy to pollute the environment. Second, the cost of pure gold plating is higher. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a cyanide-free imitation gold electroplating method for flowers, which meets the requirements of environmental protection and has extremely low cost, and can realize large-scale produ...
