Abstract

The invention relates to a brass gold color dyeing solution comprising the following components in weight percentage of 20-50% of hydrogen peroxide, 1-20% of hydrogen peroxide stabilizing agent, 0.1-6% of acidic salt, 0.1-12% of citric acid and the balance being water. The preparation method of the brass gold color dyeing solution comprises the following steps of: adding water which is 20-80% of a formula amount; then sequentially adding the citric acid, the acidic salt, the hydrogen peroxide stabilizing agent and the hydrogen peroxide by agitating; and finally adding water which is the balance of the formula amount and agitating for at least 5 minutes, and packaging to obtain a product. The invention further relates to a method for dyeing a gold color on a brass by using the brass gold color dyeing solution, which sequentially comprises the following steps of: pre-treating and dying the gold color by utilizing the brass gold color dyeing solution; and drying and closing. The method disclosed by the invention can be used for machining hardware accessories. The method for dyeing the gold color is toxin-free and pollution-free, reduces the loss of resources and the pollution to an environment, and can achieve the effects of 18K and 24K gold colors.

Description

technical field [0001] The invention relates to the field of metal surface treatment. Specifically, the invention relates to a brass gold-dyeing water, a preparation method thereof, and a method for using the brass gold-dyeing water to dye a brass substrate with gold. Background technique [0002] Gold is an important color for surface treatment. At present, there are mainly two methods of gold treatment: one is to carry out gold treatment on the metal surface by electroplating; the other is to use surface dyeing, that is, to use gold dyeing water. [0003] The cost of electroplating real gold is too high and consumes a lot of resources. Cyanide is used in traditional electroplating imitation gold, which is very harmful to environmental protection, and cyanide is highly toxic and harmful to the health of production workers. Electroplating processes that do not use cyanide have been developed. [0004] For example, CN 101798693A discloses a new gold-yellow electroplating p...
