Jewellery rose gold surface treatment plating solution, preparation method and electroplating method thereof

Abstract

The invention discloses a jewellery rose gold surface treatment plating solution, a preparation method and an electroplating method thereof. The preparation method comprises the following steps: weighing and pouring about 1 g of copper sulphate, about 120 g of ammonium sulphite, about 40 g of EDTA-2Na and about 100 g of potassium citrate into a beaker of 1L; then, adding 600 ml of water for diluting and dissolving, adding a stirring bar, placing the beaker in a heat collection type constant temperature heating magnetic stirrer, and heating and stirring the beaker for 40 minutes; taking out the beaker, and adding diamminedichloropalladium and sodium gold sulphite, wherein the palladium content of the diamminedichloropalladium is about 6 g, and the gold content of the sodium gold sulphite is about 10 g; adding water to about 950 ml, placing the beaker into the heat collection type constant temperature heating magnetic stirrer again, heating and stirring for 15 minutes, taking out the beaker, and filtering the solution; testing the acidity and alkalinity of the filtered solution by using PH paper with the specification of 6 to 9, wherein when the PH value is 8, the solution is the plating solution; if the PH value is less than 8, taking ammonia water by using a plastic cap dropper, adding half of the plastic cap dropper of the ammonia water, stirring for 2 to 3 minutes by using a glass rod, and testing the PH value again until the obtained PH value is 8; adding pure water to complement the solution to 1L to obtain the plating solution.

Description

technical field [0001] The invention relates to the technical field of jewelry treatment, in particular to a plating solution for rose gold surface treatment of jewelry, a preparation method and an electroplating method thereof. Background technique [0002] Rose gold is a metal alloy material used to produce jewelry, which usually contains gold, silver, copper and other precious metals. For example, in 8K rose gold, the gold content is 33%, and in 18K rose gold, the gold content is 75%. %. In the market, rose gold has always been loved by consumers, so people usually treat the surface of jewelry as rose gold, but the existing treatment methods have poor corrosion resistance, and the jewelry will turn rose gold after wearing for a period of time. The brightness 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-mentioned technologies, the present invention provides a rose-gold surface treatme...
