Embodiment 1

[0028] Embodiment 1: Silver-white stainless steel plate or product are as base material: carry out pretreatment earlier: mirror surface polishing, degreasing, cleaning; (1) in containing chemical composition and concentration respectively CrO 3 : 250g / L and H 2 SO 4 : In 490g / L chemical coloring solution, chemical treatment is carried out under the condition of reaction temperature of 0-60°C, through chemical oxidation coloring, oxide films with different light interference colors are formed on the surface of stainless steel (the colors are: brown, also known as Bronze, purple, blue, gray, golden yellow, purple red, sky blue, grass green, yellow green, black and their transition colors, etc.); (2) the chemical composition and concentration are respectively CrO 3 : 250g / L and H 2 SO 4 : In the electrolytic hardening solution of 2.5g / L, the applied DC current density is I=0.6A / dm 2 Power on for about ten minutes under certain conditions; (3) The chemical composition is: Na ...

Embodiment 2

[0029] Embodiment 2: Silver-white stainless steel plate or product is used as the base material: pre-treatment first: mirror polishing, degreasing, cleaning, after cleaning and drying, print a layer of pre-designed image or The intermediate protective film of the text (positive or negative image), and then light or heat cure it according to the requirements of the ink; when the chemical composition and concentration are respectively CrO 3 : 250g / L and H 2 SO 4 : In 490g / L chemical coloring solution, chemical treatment is carried out under the condition of reaction temperature of 0-60°C, through chemical oxidation coloring, oxide films with different light interference colors are formed on the surface of stainless steel (the colors are: brown, also known as Bronze, purple, blue, gray, golden yellow, purple red, sky blue, grass green, yellow green, black and their transition colors, etc.); the chemical composition and concentration are respectively CrO 3 : 250g / L and H 2 SO ...

Abstract

The making process of mirror interference color stainless steel pattern includes the following steps: soaking bright mirror stainless steel product inside chemical coloring liquid to form ligh interference color oxide film; hardening the interference color oxide film in hardening electrolyte solution, enclosing and attaching and curing one layer of image and text protecting intermediate film; eliminating unprotected color oxide film; eliminating the said protecting intermediate film; washing, stoving, coating one layer of antifouling protection film of 5-80 nm thickness; and coating one or two layers of protecting film for packing. The process is simple, convenient, high in decoration effect, high in antifouling capacity and suitable for use in household appliance, kitchen apparatus, decoration, artistic work and other industry.

Description

technical field [0001] The invention relates to a method for making pattern patterns of colored stainless steel products. Background technique [0002] Existing methods for making pattern patterns on colored stainless steel products, such as the colored stainless steel convex-concave corrosion pattern pattern plates currently used in the elevator industry, have one of the most fatal shortcomings: the corroded surface is very rough , the anti-fouling performance is very poor, and it is easy to be stained; at the same time, the uncorroded surface is very rough, and its corrosion resistance is also poor, and it is easy to be corroded in the atmosphere; therefore, its development is greatly limited. Contents of the invention [0003] The purpose of the present invention is to provide a method for making mirror bright light interference colored stainless steel pattern patterns with good decorative effect, so as to solve the problem of poor anti-pollution performance of existing...
