Problems solved by technology

[0003] However, the screen protectors currently used in the market are prone to bubbles when pasted and are not easy to discharge, which affects the aesthetics of the product after the film is applied. Moreover, the screen protectors currently used have low light transmittance, poor scratch resistance, and shield electromagnetic waves and eliminate static electricity. The performance is not strong, so the protective film on the market is still easily scratched by hard objects such as fingers and pendants, the service life of the electronic display is shortened, and the electromagnetic waves radiated by various electronic displays can cause different degrees of damage to the human body, etc. Similar problems still exist

Abstract

The invention discloses an electromagnetic wave shielding protective film. The protective film mainly comprises a main film, a composite glue layer, a metal nano layer, a composite PET (polyethylene terephthalate) film, an assembly glue layer, an assembly glue protective film, a scratch-resistant layer, a protective film glue layer and a scratch-resistant layer protective film. The protective film has the following advantages: the protective film is easy to assemble; the bubbles can be rapidly and automatically eliminated; the screen surface is free of residual glue after the protective film is removed; the protective film can be repeatedly pasted and used after being removed from the screen and has the functions of resisting scratch, resisting wear and preventing fouling; and due to addition of the metal nano layer, the screen protective film can shield the electromagnetic waves harmful to the human bodies, has the capabilities of eliminating the static electricity, reflecting infrared rays and ultraviolet rays and can be widely used for protecting the screens of various liquid crystal displays. A manufacturing method of the screen protective film is simple, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to a protective film, in particular to an electromagnetic wave shielding protective film for shielding electromagnetic waves and eliminating static electricity and a manufacturing method thereof. Background technique [0002] With the vigorous development of electronic technology, such as mobile phones, MP4, MP5, cameras, digital cameras, notebook computers and other electronic products have been introduced. In order to prevent the screen surface of electronic products from being scratched or worn, which affects the use, and to shield electromagnetic waves and eliminate static electricity, a screen protector is generally attached to the screen surface of electronic products. [0003] However, the screen protection films currently used in the market are prone to bubbles when they are pasted and are not easy to discharge, which affects the aesthetics of the products after filming. Moreover, the currently used screen protection films...
