Embodiment 1

[0040] A surface-evaporated aluminum anti-spy film with anti-reflection performance, its structure is as follows figure 1 As shown, it includes a PET layer 120 , an anti-peeping structural layer and a moth-eye anti-reflective structural layer 140 . The anti-peeping structural layer is composed of a UV photocurable resin layer 130 and an evaporated film layer 110 . The UV light-curable resin layer 130 is composed of a resin bottom layer and a resin structure disposed on the bottom layer in an array, wherein the resin structure can be a trapezoidal structure arranged in an array, or a circular frustum structure, or a prism structure. In this embodiment, The elongated structure with trapezoidal array in cross section is adopted, the trapezoid upper base is 20-200 microns, the lower base is 20-200 microns, and the height is 20-200 microns. In a preferred embodiment, the upper base of the trapezoid is 63 microns, the lower base is 106 microns, and the height is 120 microns.

Embodiment 2

[0045] A surface-evaporated aluminum anti-spy film with anti-reflection performance, its structure is as follows figure 2 As shown, its structure is roughly the same as that of Example 1, except that the truncated-cone-shaped resin structures are arranged in a rectangular array. The moth-eye anti-reflection structure layer is a cone arranged in an array, and the diameter of the bottom of the cone is less than one-half of the incident light wavelength. In this embodiment, the ratio of the depth of the cone to the bottom diameter is 0.5, and the distance between the center and the diameter of the bottom of the cone is 0.5. The ratio is 1.

Embodiment 3

[0047] A surface-evaporated aluminum anti-spy film with anti-reflection performance, its structure is as follows image 3 As shown, its structure is roughly the same as that of Example 1, except that the frustum-shaped resin structures are arranged in a regular hexagonal array. The moth-eye anti-reflective structure layer is a cone arranged in an array, and the diameter of the bottom of the cone is less than one-half of the incident light wavelength. The ratio is 8.

Abstract

The invention relates to a surface-aluminum-evaporated peep-proof film with anti-reflection performance and a preparation method thereof. The peep-proof film comprises a PET layer and a peep-proof structure layer arranged on the surface of one side of the PET layer, wherein the peep-proof structure layer comprises a UV light-cured resin layer and an evaporated film layer evaporated on the surface of the resin layer; and the surface-aluminum-evaporated peep-proof film further comprises a moth-eye anti-reflection structure layer arranged on the surface of the other side of the PET layer. The preparation method comprises an adhesive dripping process, a filling process, a UV illumination process and a demolding process. Compared with the prior art, the surface-aluminum-evaporated peep-proof film disclosed by the invention has the advantages that different surfaces can be imprinted on both side surfaces of the PET layer; and the preparation method is simple, and commercial requirements on high speed, large area, high resolution and high flux can be met.

Description

technical field [0001] The invention belongs to the technical field of optical polarization, and in particular relates to a surface-evaporated aluminum anti-spy film with anti-reflection performance and a manufacturing process thereof. Background technique [0002] The rapid development of electronic products has not only changed people's production and lifestyle, but also brought great convenience and fun to people's life. However, the problem of leakage caused during the use of electronic products has gradually attracted people's attention. Due to the large viewing angle of the screen of existing electronic products, for individuals, the security of personal privacy such as bank account numbers and passwords is not guaranteed. For enterprises, commercial secrets may also be peeped, and they face a great risk of leakage. . Therefore, an optical film is needed to reduce the risks of privacy leakage caused by the use of electronic products. [0003] At present, the anti-pe...
