Embodiment 1

[0026] A PET film with a thickness of 50 μm is used as the substrate layer;

[0027] Coating silica gel on the surface of the substrate layer, the silica gel is added with a color paste with a mass content of 0.1%, forming an adhesive layer with a thickness of 50 μm, and the peeling force between the adhesive layer and the substrate layer is 3.2gf / 25mm ; A PET film with a thickness of 50 μm is coated on the surface of the adhesive layer to form a peeling layer one;

[0028] Apply UV transfer glue on the other surface of the substrate layer for photocuring to form a structural layer with a thickness of 60 μm and a regular arrangement of a plurality of isosceles trapezoidal protrusions. The acute angle of the isosceles trapezoid is 84°, and two adjacent The interval between each trapezoidal protrusion is 16 μm, and the anti-peeping structure layer is obtained, and the shrinkage rate of the anti-peeping structure layer is 3.2%.

Abstract

The invention provides an anti-peeping film. The anti-peeping film comprises a first peeling layer, a use layer arranged on the surface of the first peeling layer and a second peeling layer arranged on the surface of the use layer, wherein the use layer comprises a hardened filling layer arranged on the surface of the first peeling layer, an anti-peeping structure layer arranged on the surface ofthe hardened filling layer, a substrate layer arranged on the surface of the anti-peeping structure layer and a glue layer arranged on the surface of the substrate layer; the second peeling layer is arranged on the surface of the glue layer. Compared with the prior art, UV glue with low shrinkage and high hardness is used as the hardening filling layer, and the anti-peeping effect produced by theanti-peeping structure layer and the color in the glue layer are combined, the protective film with high surface quality and good anti-peeping effect can be obtained, and information safety and an electronic screen can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of film materials, in particular to an anti-peeping film. Background technique [0002] With the continuous popularization of electronic equipment, information-based office is becoming more and more popular, and the protection of information is becoming more and more recognized by the public. At present, most of the anti-peeping films are used after the anti-peeping AB glue is attached to tempered glass. There are few anti-peeping films suitable for electronic equipment, and the anti-peeping tempered film suitable for electronic equipment needs to be developed urgently. Contents of the invention [0003] In view of this, the object of the present invention is to provide an anti-peeping film. The anti-peeping film provided by the present invention is a tempered film with better anti-peeping effect. [0004] The invention provides an anti-peeping film, comprising: [0005] first peeling layer; [0006] a ...
