Problems solved by technology

In the market, rose gold has always been loved by consumers, so people usually treat the surface of jewelry as rose gold. However, the existing treatment methods have poor corrosion resistance. After wearing for a period of time, the jewelry will turn rose gold The brightness of gold is not so high, so it is easy to affect its use effect

Embodiment 1

[0039] This embodiment discloses a rose gold electroplating solution, which includes 0.5-2g of copper sulfate, 100-125g of ammonium sulfite, 25-55g of disodium edetate, 85-115g of potassium citrate, palladium-containing 4-7g of palladium dichloride and 5-15g of sodium gold sulfite.

[0040] This electroplating solution can provide a kind of electroplating solution that is electroplated into rose gold on the jewelry surface, and the corrosion resistance of the electroplating solution is not good, and it can be used for a long time without fading.

[0041] 0.5g of copper sulfate, 100g of ammonium sulfite, 25g of disodium edetate, 85g of potassium citrate, 4g of palladium dichlorodiammine palladium and 5g of gold sodium sulfite. The surface of the coating is light rose gold, reaching mirror brightness, the hardness of the coating is high, the bonding force between the coating and the substrate is good, and the cathode current efficiency reaches 99%.

[0042] 1g of copper sulfate...

Embodiment 2

[0046] like figure 1 Shown, the invention discloses a kind of preparation method of rose gold electroplating solution, comprises the steps:

[0047] a, the copper sulfate of 1g, the ammonium sulfite of 120g, the disodium edetate of 40g, and the potassium citrate of 100g are put into beaker;

[0048] b. Add 600ml of water into the beaker to dilute and dissolve;

[0049] C, in beaker, add the dichlorodiammine palladium containing palladium amount 6g and the gold sodium sulfite of gold content 10g;

[0050] d. Add water to 950ml in the beaker, stir and filter;

[0051] e, after filtering, adjust to a solution with a pH value of 8;

[0052] f. Add supplement to the solution to 1L to form an electroplating solution.

[0053] The preparation method of the electroplating solution can provide a kind of electroplating solution that is electroplated into rose gold on the surface of jewelry. The electroplating solution produced by the invention has good corrosion resistance and can b...

Embodiment 3

[0061] Such as figure 2 Shown, the present invention discloses a kind of electroplating method of rose gold electroplating solution, comprises the steps:

[0062] S1. Turn on the pulse power supply heat engine for 30 minutes before electroplating, and turn on the heat-collecting constant temperature magnetic stirrer and set the temperature to 50°C;

Abstract

The invention provides rose gold electroplating liquid, a preparation method and an electric casting method. The rose gold electroplating liquid comprises 0.5-2 g of copper sulfate, 100-125 g of ammonium sulfite, 25-55 g of ethylene diamine tetraacetic acid, 85-115 g of potassium citrate, dichlorodiamminepalladium with a palladium content of 4-7 g, and sodium gold sulfide with a gold content of 5-15 g. In the rose gold electroplating liquid, the preparation method and the electric casting method, the rose gold electroplating liquid is excellent in electroplating effect, high in electroplating brightness and incapable of fading after long-time use.

Description

technical field [0001] The invention relates to the field of electroplating solution preparation, in particular to an electroplating solution, a preparation method and an electroforming method. Background technique [0002] Rose gold is a metal alloy material used in the production of jewelry, which usually contains gold, silver, copper and other precious metals, for example, in 8K rose gold, the gold content is 33%, 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. However, the existing treatment methods have poor corrosion resistance. After wearing for a period of time, the jewelry will turn rose gold The brightness of gold is not so high, so it is easy to affect its use effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rose gold electroplating solution with good electroplating effect, h...
