Multiple etching imitation cast copper process

Abstract

The present invention proposes a multi-etching imitation cast copper process, including the following steps: processing plate, preparing etchant, embossed etching, concave etching, dotted etching, color treatment, polishing and anti-oxidation treatment; Convex patterns and concave patterns are combined with etched convex dotted patterns and concave dotted patterns to make the pattern plump, and the present invention has three steps of convex pattern etching, concave pattern etching and dotted pattern etching, and the etching depth is uniform. It is not the same, so that the surface of the copper plate has a lack of beauty, and the subtle bumps and convexities are strengthened and enlarged to create a sense of unevenness, achieving the effect of a cast copper surface, and a stronger visual impact. Finally, with the treatment of color, the copper green and copper The hue is coordinated, the historical atmosphere is thick, and it has the artistic effect of ancient bronzes. At the same time, the present invention uses a special etching catalytic solution for treatment, which has higher efficiency and more obvious treatment effects. After adding the final anti-oxidation treatment, the color perception is not easy to change. Guarantee artistic effect.

Description

technical field [0001] The invention relates to the field of metal surface treatment technology, in particular to a multi-etching copper imitation casting technology. Background technique [0002] Bronze carving skills, traditional handicrafts in Hangzhou City, Zhejiang Province, one of the national intangible cultural heritage, copper carving is the continuation of ancient bronze ware manufacturing, it has been greatly developed in the Wuyue and Southern Song Dynasties. The art of Hangzhou copper carving represented by "Art" is becoming more and more mature and has been passed down from generation to generation. In June 2008, the bronze carving skill was included in the second batch of traditional skills in the national intangible cultural heritage list. [0003] In the existing copper carving techniques, chemical etching points, lines, and planes are generally used to form patterns on the metal surface. This type of pattern is relatively monotonous, and one-time etching is...

AI Technical Summary

Problems solved by technology

[0003] In the existing copper carving techniques, chemical etching points, lines, and planes are generally used to form patterns on the metal surface. This type of pattern is relatively monotonous, and one-time etching is generally used to obtain a pattern with a flat horizontal plane and no unevenness. sense, lack of visual impact effect, serious sense of modernity, does not conform to the heavy historical atmosphere of copper sculpture, therefore, the present invention proposes multiple etching imitation copper casting process to solve the deficiencies in the prior art
