Embodiment 1

[0036] (1) After spraying UV curable paint on the surface of the mobile phone case with PC substrate, use vacuum coating equipment to coat a layer of indium tin alloy on the surface; (2) Spray UV curable photosensitive ink on the metal surface; (3) Place it on the workpiece A negative with a black graphic of the target decorative pattern (graphics such as figure 1 As shown), the thickness is 0.18mm, the sheet is tightly attached to the surface by vacuuming, and the exposure energy is 85mj / cm in a standard UV exposure machine. 2 , the ink in the light-transmitting area is cured, while the ink in the opaque area is not cured; (4) After exposure, use a 0.95% mass fraction of sodium carbonate solution as a developing liquid to spray in the developing equipment transported at the standard level , the ink in the opaque area is removed, and the metal layer below it is exposed, while the ink layer in the light-transmitting area remains on the surface of the metal layer; (5) On standar...

Embodiment 2

[0038] (1) After spraying UV curable paint on the surface of the mobile phone case of the PC substrate, coat a layer of aluminum on the surface with vacuum coating equipment; (2) Spray UV curable photosensitive ink on the metal surface; (3) Place a piece of paint on the workpiece Negative film with a black graphic of the target decorative pattern (e.g. image 3 As shown), the thickness is 0.18mm, the sheet is tightly attached to the surface by vacuuming, and exposed in a standard UV exposure machine, the exposure energy is 80mj / cm 2, the ink in the light-transmitting area is cured, while the ink in the opaque area is not cured; (4) After exposure, use a 0.95% mass fraction of sodium carbonate solution as a developing liquid to spray in the developing equipment transported at the standard level , the ink in the opaque area is removed, and the metal layer below it is exposed, while the ink layer in the light-transmitting area remains on the surface of the metal layer; (5) On sta...

Embodiment 3

[0040] As in Example 1, but the plated metal is silicon-aluminum alloy, and the developer solution used is dichloromethane solvent.

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...
