Problems solved by technology

[0005] The above-mentioned method needs to use the electroplating process, so it will generate waste water and heavy metals and pollute the environment, thereby creating environmental problems; moreover, the coating uniformity of the transparent paint layer is not good, and after a period of use, the transparent paint Layers come off easily

Embodiment Construction

[0018] see figure 2 , the manufacturing method disclosed in the present invention includes the following steps and implementation content:

[0019] The metal surface treatment step (22) is to take the metal body of non-copper material, and grind and polish the surface of the metal body; the metal body of the above-mentioned non-copper material itself has a silvery white color, or has a silvery white color after processing color;

[0020] The first spraying step (24) is to spray a primer layer on the surface of the polished metal body; especially, the color of the primer layer can be selected as a dark person;

[0021] The wire drawing step (26) is to grind the primer layer with a machine, so as to destroy part of the primer layer to produce a line-shaped or block-shaped hollow structure with different thicknesses, and to expose the surface color of the metal body. in the damaged area or location;

[0022] The second spraying step (28) is to be coated on this primer layer w...

Abstract

The invention discloses a method for making an antique color metal surface, which comprises the steps of: metal surface treatment, first spraying, wire-drawing, second spraying and surface curing; wherein a coating used in the second spraying is a colorful and diaphanous powder coating, so that an antique color, such as antique brass or antique silver can be presented by matching the metal color subjected to the wire-drawing with the color of the powder coating; furthermore, the surface curing step can make powder coating uniform, which further improves the protectiveness and uniformity of the metal surface.

Description

【Technical field】 [0001] The invention relates to the technical field of metal surface processing, in particular to a method for coloring non-copper or non-silver metal so that the surface finally presents an antique copper or antique silver color. 【Background technique】 [0002] Generally common copper or silver antique objects, due to long-term oxidation, the surface color will show a simple texture; consumers have a high degree of acceptance and favor for this color; however, the number of antique objects There are not many and the price is high, which is not available to ordinary people. [0003] Most of today's antique copper (color) or antique silver (color) utensils use surface processing to make the non-copper or non-silver metal surface present a color and texture similar to or close to bronze or ancient silver; Artifacts in antique copper or antique silver can be produced in large volumes and at low cost. [0004] see figure 1 , the traditional surface processin...
