Jewelry white surface treatment plating solution, preparation method and electroplating method thereof

Abstract

The invention discloses a jewelry white surface treatment plating solution, a preparation method and an electroplating method thereof. The preparation method comprises the steps that about 90 g of ammonium sulfamate and about 20 g of nickel aminosulfonate are weighed and poured into a 1 L beaker; 700 ml of water is added for dilution and dissolution; a stirrer is added, the beaker is added into a thermal-collection type constant temperature heating magnetic stirrer for performing heating and stirring for 40 min; the mixture is taken out, and then dinitroso-diamine palladium is added, wherein the content is palladium is about 6 g; water is added to reach about 950 ml and the mixture is added into the thermal-collection type constant temperature heating magnetic stirrer for performing heating and stirring for 15 min; the beaker is taken out, a solution is filtered, the filtered solution is subjected to testing of PH value through PH paper of the specification of 6-9, if the PH value is 8-9, the plating solution is obtained; if the PH value is not 8-9, a dropper is used for taking ammonium hydroxide, a half amount of the ammonium hydroxide in the dropper is added, a glass rod is used for performing stirring for 203 min, then, the PH value is tested, and the steps are repeatedly executed till the PH value is 8-9; finally, pure water is added to supplement the solution to reach 1 L so that the plating solution can be formed.

Description

technical field [0001] The invention relates to the technical field of jewelry treatment, in particular to a white surface treatment plating solution for jewelry, a preparation method and an electroplating method thereof. Background technique [0002] Treating the surface of jewelry to white is very popular with consumers, so people usually treat the surface of jewelry to white, but the existing treatment methods have poor corrosion resistance, and the white brightness of jewelry after wearing for a period of time It is not so high, so it is easy to affect its use effect. Contents of the invention [0003] Aiming at the deficiencies in the above technologies, the present invention provides a white surface treatment plating solution for jewelry, a preparation method and an electroplating method thereof. The white surface electroplating effect is good, the electroplating brightness is high, and the color will not fade after long-term use. The phenomenon. [0004] In order ...
