Abstract

The invention provides an anti-static screen protection film and a preparation method thereof. The anti-static screen protection film sequentially comprises an anti-static layer 1, a hardened coatinglayer 2, a PET base material layer 3, a hardened coating layer 4 and a release film layer 5 from top to bottom; the preparation method comprises the steps: 1) respectively preparing coatings of the hardened coating layer 2 and the hardened coating layer 4; 2) uniformly coating one surface of the PET base material layer 3 with the coating of the hardening coating layer 2 and hardening to form the hardening coating layer 2; 3) uniformly coating the other surface of the PET base material layer 3 with the coating of the hardening coating layer 4 and baking; and 4) pasting the release film, pastingthe release film layer 5 on the surface, coated with the coating of the hardened coating layer 4, of the PET base material layer 3, and curing to obtain the hardened coating layer 4 clamped by the PET base material layer 3 and the release film layer 5. The screen protection film prepared by the preparation method has good antistatic performance, wear resistance, blue light resistance and long service life.

Description

technical field [0001] The invention relates to a preparation method of an antistatic screen protective film and a protective film prepared by the preparation method. Background technique [0002] In the prior art, most of the mobile phone protective films sold on the market are tempered PET protective films. Wherein, the layered structure of the film includes an anti-fingerprint coating layer, a tempered glass layer, a glue layer, a PET substrate layer, a glue layer, and a release film layer that are stacked together in sequence. Although the protective film is easy to produce and low in cost, due to the limitation of its material, its impact resistance and durability will be relatively weak. Contents of the invention [0003] The invention provides an antistatic screen protective film and a preparation method thereof. The antistatic screen protective film comprises from top to bottom: an antistatic layer 1, a hardened coating 2, a PET base material layer 3, a hardened c...
