A gold decoration process for ceramic products suitable for industrial production

Abstract

The invention provides a ceramic product gold decoration technique suitable for industrial production. The technique comprises steps as follows: (1) melting gold with strong acid; (2) reducing the gold to pure gold powder with ethanol; (3) adding resin, metal rhodium and bismuth, and mixing the mixture to prepare gold powder paste; (4) printing the gold powder paste on the surface of ceramic patterned paper to prepare gold decorated patterned paper; (5) producing a ceramic product body; (6) pasting the gold decorated patterned paper on the surface of a ceramic product, compacting the paper, and applying transparent ceramic glaze; (7) performing decorating firing in a kiln, naturally cooling the ceramic product and taking the ceramic product out of the kiln; (8) performing surface treatment; (9) checking, packaging and storing the ceramic product. The ceramic product adopting the decoration technique is high in grade, high in quality, magnificent, bright in color, friction-resistant and antioxidant, cannot fade easily, can prevent harmful substances such as lead, cadmium and the like from dissolving out, and is sanitary and safe; besides, the method is adaptable to industrial production, high in production efficiency, lower in production cost and adaptable to fields of domestic ceramic, art ceramic and the like, the domestic ceramic and the art ceramic are raised to a new grade, and the increasing material and cultural life demand of people is met.

Description

technical field [0001] The invention relates to a decoration process method of ceramic products, in particular to a gold decoration process method suitable for industrial production of ceramic products. Background technique [0002] The traditional surface decoration of ceramic products is mainly done by decals or artificially painted patterns and colors. Although it can achieve a certain decorative effect, the color of the product is not durable enough, and it will fade after a long time, affecting the decorative effect; And some of the chemical pigments used in the decal paper or artificial painting contain harmful substances such as lead and cadmium. If they are used to decorate daily tableware, these harmful substances are easy to leak out and cause harm to the human body and affect people's health. and the grade of the pottery products that adopt this decoration is also not high, can not satisfy the demands of people's increasing material and cultural life. Therefore, ...

AI Technical Summary

Problems solved by technology

The ceramic products made by this technical scheme are of high grade, elegant quality, bright colors, friction resistance, oxidation resistance and no fading, and will not dissolve harmful substances such as lead and cadmium, and are hygienic and safe; The flat gold sheet of 0.1-0.22mm after hammer pressing generally needs to be processed by manual hammer pressing, which has low production efficiency and high production cost, and is not suitable for industrial production, which also limits its popularization and application.
