Colorful color-changing mobile phone shell with anti-counterfeiting and anti-scratching functions and manufacturing method thereof

Abstract

The invention provides a colorful color-changing mobile phone shell with anti-counterfeiting and anti-scratching functions. A complex adhesive layer is used for pasting a colorful color-changing PET (PET (Poly Ethylene Terephthalate) substrate layer on an insulation plastic layer; the anti-scratching layer is arranged on the upper surface of the colorful color-changing PET substrate layer; the anti-counterfeiting layer is arranged on the upper surface of the anti-scratching layer. The manufacturing method of the mobile phone shell comprises the following steps: extruding by virtue of a twin-screw extruder to form the insulation plastic layer, coating the upper surface of the insulation plastic layer with the complex adhesive layer, pasting the colorful color-changing PET substrate layer on the upper surface of the complex adhesive layer; curing the upper surface of the colorful color-changing PET substrate layer by virtue of an UV device to obtain the ant-scratching layer; and finally pasting anti-counterfeiting labels made from anti-counterfeiting ink on the upper surface of the anti-scratching layer or directly spraying codes on the upper surface of the anti-scratching layer by virtue of the anti-counterfeiting ink so as to obtain the anti-counterfeiting layer. The mobile phone shell is capable of effectively preventing objects such as fingers, pendants and the like from scratching and rubbing the mobile phone shell; the manufacturing method of the mobile phone shell is simple, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to a mobile phone case, in particular to a seven-color color-changing mobile phone case with anti-counterfeiting and anti-scratch functions and a process method thereof. Background technique [0002] At present, there are a large number of fake and counterfeit mobile phones on the market, often under the guise of a certain famous brand.

Problems solved by technology

[0002]Currently, there are a lot of shoddy and counterfeit mobile phones on the market, often under the guise of a certain famous brand. , Consumers are damaged while also affecting the goodwill of regular brands. Therefore, merchants of regular brands generally affix unique anti-counterfeiting labels on the mobile phones they sell to prevent this kind of situation. Generally, consumers do not have special equipment to identify them. , and the existing film products of this type cannot use anti-counterfeiting labels or can not directly spray anti-counterfeiting inkjet ink, the reason is that in the prior art, alkyd resin, vinyl resin, phenolic resin, etc. are often used as the main raw materials to produce All kinds of inkjet inks, and this type of inkjet ink is difficult to adhere to glass, polypropylene film, PET film, light-cured resin layer and other materials with smooth surface, these inks are easy to be wiped off after spraying; especially It is generally necessary to add some luminous or discolored powders to the anti-counterfeiting inkjet inks used to make anti-counterfeiting trademarks or directly spray. Adding these powders will further seriously affect the adhesion of the ink to the smooth surface.
