Abstract

The invention relates to a method for displaying a three-dimensional pattern through vacuum coating. The method comprises the following steps of: machining a PET (polyethylene terephthalate) film into preset shape and size; carrying out optical vacuum evaporation on the surface of the PET film for preparing a continuous metal-texture thin film, and then coating a first titanium dioxide film layer, a second silicon dioxide film layer and a third titanium dioxide film layer in sequence; placing the coated PET film below a printer screen board, carrying out screen printing on a discontinuous metal-texture silver thin film, and then putting the printed PET film into a baking oven for baking; putting the PET film after screen printing into a stripping solution for soaking and stripping; and allowing one side of the PET film after coating and screen printing to be stuck with a glass panel, and carrying out defoaming treatment after the completion of film laminating. The products prepared by the method are strong in metal texture, good in weatherability, stable in preparation process and suitable for mass production, and effectively solves the defects of the prior art.

Description

technical field [0001] The invention relates to surface decoration technology, in particular to a method for realizing three-dimensional pattern display through vacuum coating. Background technique [0002] With the rapid development of the mobile electronic technology industry in recent years, the function of electronic equipment is no longer the only goal consumers pursue. The casing and capacitive touch screen glass touch panel can better meet people's requirements for aesthetics, so the development of these appearance processes has become an irreplaceable part of mobile phone decoration. [0003] Since the shell of metal or metal film layer will shield the signal emitted by the mobile phone, mobile phone manufacturers hope to obtain a mobile phone shell that has a metal effect and will not affect the signal of the mobile phone. At present, the domestic vacuum coating method for preparing discontinuous film layers of mobile phone shells usually uses indium tin alloy as t...
