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 surface 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

Embodiment 1

[0036] (1) After spraying UV curing primer on the surface of the PC mobile phone case, spray UV curing photosensitive ink; (2) Place a piece of negative film with black graphics of the target decorative pattern on the surface of the mobile phone case sprayed with UV curing photosensitive ink (Such as figure 1 As shown), the thickness is 0.18mm, the film is closely attached to the surface by vacuuming, and then exposed in a standard UV exposure machine with an exposure energy of 85mj / cm 2 . The ink in the light-transmitting area is cured, while the ink in the opaque area is not cured; (3) After exposure, use a sodium carbonate solution with a mass ratio of 0.85% as a developing liquid to spray in the developing equipment transported at a standard level , the ink in the opaque area is removed by the developer solution, while the ink layer in the transparent area remains on the surface of the material; (4) The vacuum coating equipment further coats a layer of indium tin alloy on...

Embodiment 2

[0038] (1) After spraying UV curing paint on the surface of the ABS bluetooth earphone shell, spray UV curing photosensitive ink; image 3 As shown), the thickness is 0.18mm, the sheet is tightly attached to the surface by vacuuming, and then exposed in a standard UV exposure machine with an exposure energy of 50mj / cm 2, the ink in the light-transmitting area solidifies, while the ink in the opaque area does not solidify; (3) after exposure, use a sodium carbonate solution with a mass ratio of 1.2% as a developing liquid in a developing device transported at a standard level. The ink in the opaque area is removed by the developing solution, while the ink layer in the transparent area remains on the surface of the material; (4) The vacuum coating equipment further coats a stainless steel metal layer on the surface of the material, and the metal layer above the transparent area and The ink layer is attached, and the metal above the rest of the area is directly attached to the su...

Embodiment 3

[0040] As embodiment 1, but what sprayed earlier on the surface of the mobile phone case of PC material is thermosetting varnish; The metal plated is aluminum; The developing liquid used is tetramethylammonium hydroxide solution.

Abstract

The invention belongs to the field of surface chemical treatment or the field of plating materials with metal materials, and relates to a method for performing metallization decoration on the surface of non-metal materials and a product thereof. Spray UV-curable photosensitive ink on the surface of the material to be decorated, and then cover the ink with a light-transmitting negative film in a part of the target pattern, and then expose and cure the ink in the light-transmitting part under UV light, and then treat it with a developing solution to remove the unsightly ink. After the ink is cured, the metal layer is plated, and the ink layer and the metal layer plated on the ink layer are removed by using a film remover to obtain a patterned metal layer. This method can obtain lines and spacings of 50 microns or even finer. The fineness of the obtained product enables the product to present a variety of pattern decoration effects that cannot be presented by the existing technology, and the method is highly controllable and reproducible. High rate.

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...
