Embodiment Construction

[0008] The technical solutions of the present invention will be further specifically described below through examples.

[0009] Example. This example is the purple gold engraving copper carving process of large-scale copper paintings, according to the following procedures:

[0010] 1. Etching: Carry out photo-etching and cleaning on the copper plate according to the design graphics, and obtain four major patterns of houses 1, flying apsaras 2, trees 3, and plantains 4, which are composed of etched outlines.

[0011] 2. Oxidation: Apply a protective layer to the aforementioned four parts, and oxidize the background part 5 without pictures and texts with sulfide to obtain the background part 5 whose oxidized color is dark purple;

[0012] Partially protect the parts of house 1, tree 3, and plantain 3 (excluding flowers), and carry out secondary oxidation with different formulas of sulfide to obtain light purple house 1, tree 3, and plantain 3 (excluding flowers);

[0013] 3. M...

Abstract

The present invention relates to a purple red copper etching-carving process, it includes the etching procedure of picture and characters portion and cleaning procedure, and it is characterized by that it also has the following procedures: (1) local oxidation procedure on base surface and / or first etched surface and local secondary oxidation procedure on the picture and characters etched surface; (2) in which at least making once purple colour effect oxidation; and (3) making local moving plating procedure so as to obtain the copper picture product whose picture and characters have three kinds of more than three kinds of metal pure colours and purple tone oxidation colour.

Description

technical field [0001] The invention relates to a technique for producing a decorative effect on a copper plate, in particular to a purple gold copper carving technique. The copper painting made by the technique is based on purple and partially plated with gold and silver. Background technique [0002] Chinese patent application 88105267.1 discloses a "copper-etched mural and its technique", which is to enlarge the drawing on the copper plate → partially apply glue → dry → corrode → remove glue → bake → surface treatment (i.e. once Etching method plus embedded color) to complete the production of copper etching murals. However, this technique has the following shortcomings. First, the decorative effect of the one-time etching method is single, and second, the embedded color baking covers up part of the copper characteristics. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, pro...
