Problems solved by technology

[0004] In order to make the appearance of the whole mobile phone harmonious and uniform, indium tin alloy, the coating film material, is coated on the glass surface with poor adhesion and poor mechanical strength. Screen printing ink on the coating surface is easy to scratch the coating surface. Indium tin alloy is prepared on the glass surface. The surface is very easy to oxidize when exposed to the air, and the oxidized indium tin film layer will change color, which does not show the original neutral characteristics of indium tin alloy, so it is not suitable for mass production

Abstract

The invention discloses a discontinuous metallic silver membrane and a membrane coating method for the same. The membrane is coated on a glass base plate, and comprises a titanium dioxide membrane layer, a silicon dioxide membrane layer, a titanium dioxide membrane layer, a silicon dioxide membrane layer, and a titanium dioxide membrane layer in sequence from the glass base plate to the outside; the membrane coating method comprises the steps as follows: a silver membrane is prepared through optical vacuum membrane coating, conducting the silk screen printing to a membrane-coated product, and finally conducting the membrane layer stripping. The discontinuous metallic silver membrane has the advantages of strong adhesion power, good resistance to mechanical strength, strong metallic feeling, good weather resistance, and suitability for mass production; and moreover, the membrane coating surface is not scratched by ink silk-screened on the membrane coating surface; the preparation process is stable; and the membrane layer is not easily oxidized after being exposed in the air for a long time.

Description

technical field [0001] The invention relates to a vacuum coating film for a glass panel of a mobile phone touch screen, in particular to a silver-white film with a discontinuous metallic texture and a coating method thereof. Background technique [0002] With the rapid development of the mobile phone industry in recent years, functions are not the only goal consumers pursue. The appearance of mobile phones also attracts the attention of the public. Therefore, mobile phone casings with metallic luster and colors and capacitive touch screen glass touch panels have developed into an irreplaceable part of mobile phone decoration. [0003] Since the shell of metal or metal film 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. The coating method uses indium tin alloy as the coating raw material. For example, Patent Application No. 20112006...
