Surface metallization decoration method

Abstract

The invention belongs to the field of surface chemical treatment or material plating with application of a metal material, relating to a method of performing metallized decoration on the surface of nonmetal material and products thereof. The method comprises the steps of: plating a metal layer on a surface of an object to be decorated, spraying UV cured photosensitive ink, and placing a negative film which is partly light-transmissive on the UV cured photosensitive ink, then exposing in UV light, wherein the ink in the light-transmissive area is cured, and the ink in the lighttight area is not cured; further processing by developing liquid, removing the ink in the lighttight area to expose the metal layer under the ink, spraying etching liquid for etching, wherein the metal layer is removed by etching and the metal layer under the cured ink layer is reserved; and then removing the ink layer on the metal layer by a film removing agent, thereby forming a metal pattern by exposing the metal layer. According to the method, lines and spaces in 50 microns or less can be obtained, and the products can present pattern decorative effects which cannot be presented by the prior art due to the degree of fineness of the obtained products.

Description

technical field [0001] The invention belongs to the field of surface chemical treatment or the field of plating materials with metal materials, and in particular relates to a method for performing metallization decoration on the surface of non-metal materials. Background technique [0002] Decorating with metal on the surface of plastic, ceramics, glass and other materials is a popular decoration method in recent years, which can improve the aesthetic feeling of materials and the grade of products. At present, the technical treatment of the surface of the material is mostly to use a coating machine to coat a metallized decorative film and laser engraving, or to solidify the metal powder on the surface of the material and then solidify the transparent layer. However, it is difficult to obtain metallized decorative films in local areas (such as various metallized patterns) only by using these methods. Even if the products obtained by combining some other methods, there will be...

AI Technical Summary

Problems solved by technology

[0003] 1) It cannot generate high-definition lines and spacing;

[0004] 2) The production time is quite long;

[0005] 3) The controllability of the production process is low, and the yield is low;

[0006] 4) Most of them are limited to planar structures;

[0007] 5) The laser engraving process cannot solve the problem of rough substrate at the laser engraving position

[0008] Especially on three-dimensional products, there is still no better method for finely modifying the surface of the product with metallized patterns; only very expensive laser equipment can make three-dimensional patterns, and for complex patterns, the production of laser methods very slow
