Problems solved by technology

[0002] At present, the surface decoration of jewelry and jade products mainly adopts the following processing techniques. 1. Manual filigree method. First, carve fine grooves on the surface of jewelry by hand or computer, and then fill gold and silver filaments by hand. Then smooth the surface, this method belongs to the traditional manual technique, not only the process is difficult, the efficiency is low, and the labor cost is high, it is not suitable for large-scale mass production; Carve out decorative grooves, and then use a brush to brush in gold powder paint or gold foil. This method has poor adhesion to gold powder or gold foil, is easy to fade, is not resistant to sweat and water, and is not suitable for close-fitting wear; , Paste the decal on the surface of the jewelry, and then bake at high temperature to transfer the decoration on the decal to the surface of the jewelry. This processing technology requires a high temperature of 800 ° C. Natural gemstones will be chapped, and the material and color will be seriously damaged. , although low-temperature flower paper has appeared in recent years, its pattern adhesion is poor, it is not resistant to abrasion, and it is not resistant to sweat erosion

Embodiment 1

[0012] The manufacture of embodiment 1 gold-removing liquid:

[0013] According to the above technical scheme, first add 400g sodium cyanide to 1kg of LZ101 concentrated gold stripping solution and stir, then add 7 liters of clear water to dilute and stir evenly. The stripping time is about 40-50 seconds.

[0014] The titanium stripping solution is prepared by mixing sodium hydroxide solution with a concentration of 3%-10% and hydrogen peroxide, and the mixing ratio is 1:1.

Abstract

The invention discloses a gold decoration process on a precious stone. The method comprises the steps of plating a titanium nitride TiN film layer on the surface of a the precious stone by vacuum ion plating, then plating a layer of a gold film on the surface of the precious stone through vacuum plating, printing preset grain decorations on the gold film of the precious stone by using printing ink, and drying the printing ink at the drying temperature of 150-300 DEG C; then eliminating the portion of the gold film, which is free from printing ink shielding by using gold eliminating liquid; eliminating the portion of a titanium metal film layer, which is free from printing ink shielding by using a titanium eliminating solution; and finally immersing the products of which the portions of titanium and gold, which are free from printing ink protection are eliminated, in acetone, and wiping out the protection printing ink on the surface by using the acetone. According to the process, the natural non-conducting precious stone with complex components, the titanium gold compound and gold are combined firmly, the overall appearance attractiveness and ornament of the precious stone are improved greatly, and the process effects and the process aesthetic perception of 'wire inlay' and 'slivering and gold plating' in traditional process and techniques can be achieved with low cost.
