Problems solved by technology

[0002] Existing metal decorative panels are painted or electroplated on the surface of smooth metal panels, and the color is single, easy to be scratched and difficult to repair; if it is two-color, it is silk screen or sprayed on the surface of the coating again. Different colors of pigments or paints, such metal decorative panels are easy to fade or part of the color is delaminated after a long time of use, the color is not good, and the decorative effect is not good

example 1

[0071] Example 1: If figure 1 , figure 2 Shown: an etched two-color decorative metal plate, the etched two-color decorative metal plate includes a metal plate 1, the surface of the metal plate 1 is etched with a concave pattern 11, and the non-concave part is opposite to a raised pattern 12; the concave pattern 11. The raised pattern 12 is colored with a black titanium coloring layer (black), and the black titanium coloring layer 2 is vacuum-plated with a PVD coating pattern layer (for example: titanium gold) PVD coating pattern layer (titanium gold) and a black titanium coloring layer ( The color of black) is different, and the part of the black titanium coloring layer 2 not covered by the PVD coating pattern layer forms a delamination pattern (hollow pattern) relatively, and the black titanium coloring layer can be seen through the delamination pattern (hollow pattern). The black titanium coloring layer within the hollow area of ​​the pattern (hollowout pattern) also relat...

specific Embodiment 1

[0074] A production process for etching two-color decorative metal plates is characterized in that it comprises the following steps:

[0075] 1) Lift the metal plate onto the screen printing platform, and print the pattern with ink through the screen printing screen; this pattern can be any design pattern style; the selected metal plate is a stainless steel metal plate;

[0076] 2) Dry the ink that has been screen-printed on the surface of the metal plate in an oven to cure the ink on the surface of the metal plate;

[0077] 3), transport the metal plate with solidified ink to the etching machine, etch the surface of the metal plate not covered by the ink with etching solution, so that the surface of the metal plate is etched with a concave pattern;

[0078] 4) Transport the metal plate with etched patterns to the ink removal equipment, soften and wash the previously printed ink with sodium hydroxide, so that the surface of the metal plate is formed with concave patterns due t...

Abstract

The invention discloses a production process of an etched two-color decorative metal plate. The production process comprises the following steps of: performing silk-screening of patterns on a metal plate by using printing ink, drying the metal plate, using etching liquid to etch the surface of the metal plate which is not covered by the printing ink, and cleaning the printing ink, so that the concave pattern and the convex pattern are formed on the surface of the metal plate; then coloring a black titanium coloring layer, and coating a PVD (physical vapor deposition) coating layer in vacuum, wherein the color of the PVD coating layer is different from that of the black titanium coloring layer; performing silk-screening of the patterns by using the printing ink again, drying, then using a deplating agent to remove the PVD coating layer which is not covered with the printing ink, cleaning the printing ink to obtain a PVD coating pattern layer, and baking varnish, wherein the baking varnish completely covers the delaminated patterns and the PVD coating pattern layer to form a baking varnish layer for realizing surface protection, and the front two colors can be clearly seen through the baking varnish layer; and performing the surface film pasting protection and completing. The production process can be used for producing a plurality of decorative metal plates with different colorsfor free selection by customers; and the decorative metal plate has the advantages of attractive surface decoration, high grade, good overall decorative effect and the like.

Description

technical field [0001] The invention relates to a production method of a decorative metal plate, in particular to a production process of an etched two-color decorative metal plate. Background technique [0002] The existing metal decorative panels are painted or electroplated on the surface of the smooth metal plate, and the color is single, easy to be scratched and difficult to repair; if it is two-color, it is silk screen or sprayed on the surface of the coating again. Different colors of pigments or paints are formed. Such metal decorative panels are easy to fade or part of the color is delaminated after a long time of use. The color is not good and the decorative effect is not good. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a production process for etching two-color decorative metal plates with high production efficiency, reasonable process design and stable color. [0004] A production process f...
