Embodiment 1

[0015] Embodiment 1: This metal surface shadow etching special effect process mainly includes the following steps:

[0016] (1), the metal plate is surface-leveled and cleaned, and the basic figure that needs to be etched is selected; the anti-corrosion printing material is printed by silk screen at the place complementary to the basic figure, so that there is no anti-corrosion printing material on the basic figure;

[0017] (2) Etch the basic pattern on the metal plate by chemical etching or electroetching, and the depth is controlled between 0.2-0.4mm;

[0018] (3), select the texture graphics that need to be etched inside the basic graphics, and print anti-corrosion printing materials by screen printing at the places complementary to the basic graphics and texture graphics, and texture graphics and figurative patterns can be made according to design requirements. Or make dot graphics.

[0019] (4), by chemical etching or electroetching, etch the texture pattern, the depth ...

Embodiment 2

[0023] Embodiment 2: The difference from Embodiment 1 is that the steps (3) and (4) are repeated after the step (4), and the secondary texture pattern is etched inside the texture pattern, and the depth is controlled at 0.1-0.2 Between mm, the depth is based on the texture graphic plane after etching, so that the surface of the metal plate presents three levels, and so on, up to four levels.

Abstract

The present invention relates to the manufacturing technology of metal surface image etching particular effect, comprising the steps as follow:(1) the etched basic figure is chosen, corrosion proof paint is printed on the places which are complemented with the basic figure through a web;(2) the basic figure is etched on the metal board;(3) corrosion proof paint is printed on the places which are complemented with the texture figure through a web;(4) the texture figure is etched to lead the surface of the metal board to appear two layers;(5) the corrosion proof paint printed on the surface is washed out, the colored baking varnish is fully spayed and then is roasted to dry; the spray-paint surface is burnished to abrade the surface spray-paint of the non-etched figure, and then the whole body is burnished;(6) a protective disposal is maken to the burnished metal surface after being wiredrew and polished. The beneficial effect of the present invention is that the metal surface appears particular texture efficiency after multiple flows such as etching, coloring and burnishing, and has the advantages of clear layer, colorful and firm adhering of the color, and having particular artistic effect.

Description

technical field [0001] The invention relates to the field of etching, and mainly relates to a metal surface shadow etching special effect process. Background technique [0002] The surface graphic representation of existing metal surfaces (stainless steel, copper, aluminum, iron, etc.) mostly adopts flat printing to present shapes and colors, and a large number of etching methods are used to present unevenness. Generally, one-time etching is used for single-color and multi-color , the pursuit of a smooth surface, less blocky color changes, and poor layering, it is mostly used for nameplate production. In the past, the texture effect was mostly realized by the formula and time of etching solution, which was difficult to control, could not be produced on a large scale, and the effect change was also difficult to control. Contents of the invention [0003] The present invention aims to solve the above-mentioned existing shortcomings, and provides a metal surface shadow etchi...
