Example Embodiment

[0022] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention, but the examples cited are not intended to limit the present invention.

[0023] A method for preparing privacy film, the specific preparation steps are as follows:

[0024] S01: Carry out UV resin coating molding on the PET layer 1. In order to distinguish easily, this UV resin is named the first transparent resin, and the first transparent resin layer 2 covering the PET layer 1 and several rows are evenly distributed The protrusion unit 3 on the first transparent resin layer 2, such as figure 1 As shown, the protrusion unit 3 can be a rectangular parallelepiped, a prism, or figure 1 As shown, the cross section of the protruding unit 3 is trapezoidal, and the upper base is smaller than the lower base, and the manufacturing p...

Abstract

The invention discloses a preparation method of a peep-proof membrane, comprising the following steps: 1) coating a PET layer with UV resin for forming so as to prepare a first transparent resin layer which covers the PET layer and several columns of raised units which are uniformly distributed on the first transparent resin layer; 2) carrying out wet-type coating in gaps between the raised units with a black or grey filler; 3) removing a surface layer formed by the black or grey filler on the top of the peep-proof membrane; 4) roasting: a solvent in the filler is volatilized, solid components in the filler are deposited on the bottom of the gaps and a thin layer is adhered to the side surface of the gaps; and 5) second transparent resin is filled between the raised units. Refractive index of the second transparent resin is lower than refractive index of the first transparent resin, and a protection layer is formed on the top of the peep-poof membrane by the second transparent resin. Light transmittance of a viewable area is enhanced. Visual effect is better. User experiment is more comfortable. In addition, the peep-proof function outside the viewable area of the peep-proof membrane provided by the invention is the same with as effects of a traditional peep-proof membrane.

Description

technical field [0001] The invention relates to a preparation method of an anti-peeping film. Background technique [0002] The anti-spy film adopts the world-leading ultra-fine louver (MICROLOVER) optical patent technology, so that the information displayed on the screen is exclusively for the user to read from the front. The viewing area is 60 degrees, that is, when viewed from the left, it is 30 degrees from the leftmost side of the screen Visible within, when viewed from the right, within 30 degrees from the far right of the screen. Anyone outside the viewing area can only see a pitch-black picture. Effectively protect commercial secrets and personal privacy, users can use computers, mobile phones and other electronic products as they like in the office, on the road, in public places and in any environment. [0003] The traditional anti-spy film preparation method is a two-stage process, the first stage: UV coating or hot embossing to produce a prism structure; the sec...
