Double-side adhesion hard screen protection film, production method thereof and use method thereof

Abstract

The invention discloses a double-side adhesion hard screen protection film. The double-side adhesion hard screen protection film comprises a PET base material layer. An organosilicone bottom adhesive layer is arranged on one side surface of the PET base material layer, and an acrylic ester adhesive layer is arranged on the other side surface the PET base material layer. A release film layer is arranged on the surface of the acrylic ester adhesive layer. An organosilicone surface adhesive layer is arranged on the surface of the organosilicone bottom adhesive layer in a coating mode, and another release film layer is arranged on the organosilicone surface adhesive layer in an attaching mode. Due to the adoption of the structure and the method, the double-side adhesion hard screen protection film has the advantages that the adhesion strength is high, the light transmission performance is good, and the film has high fastness, will not bubble or be scratched easily and has compression resistance; bottom adhesives are additionally applied before applying organosilicone adhesives, and therefore the organosilicone adhesive layers and the PET base material layer can be bonded more firmly; the film is ultrathin and can exhaust air quickly and automatically in the adhering process, and adhesive residues will not remain when the protection film is replaced; the film is stable in performance.

Description

technical field

[0001] The invention relates to a double-sided adhesive hard screen protective film and its production and use methods. Background technique

[0002] At present, the screens of desktop computers, notebook computers, and LCD (plasma) TVs all use soft screens. This kind of soft screen cannot touch hard things. Deformation, so the soft screen is not suitable for promotion on portable electronic products such as mobile phones, tablet computers, and notebook computers. The general protective film is made of PE (polyethylene). The PE film has poor light transmission and low strength, and cannot effectively protect the toughened glass hard screen. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a double-sided adhesive hard screen protective film and its production and use methods to achieve high light transmittance, the adhesive surface is not easy to foam, and has no watermark. There is no purpose of ...

Embodiment Construction

[0014] Such as figure 1 A kind of hard screen protective film pasted on both sides as shown, comprises PET (polyethylene terephthalate) substrate layer 1, and PET substrate layer 1 side surface is provided with organic silicon primer layer 2, can make organic The silicone layer can be combined more firmly with the PET substrate. The surface of the other side of the PET substrate 1 is provided with an acrylate adhesive layer 3, the surface of the acrylate adhesive layer 3 is provided with a release film layer 4, and the surface of the silicone primer layer 2 is coated with a silicone surface adhesive layer 5. Another layer of release film 6 is pasted on the surface of the adhesive layer 5 .

[0015] A production method for sticking a hard screen protective film on both sides, the method comprises the following steps:

[0016] a) On one side of the PET base material, first coat the silicone primer, then coat the silicone surface glue and then apply the release film;
