Problems solved by technology

However, most of the protective leather cases used in the market now have a layer of transparent PET anti-scratch protective film on the front. Since the protective film is only treated with anti-scratch treatment, when people use this product, when protecting When the film surface is attached to the display screen, due to the film interference phenomenon, there will be some concentric rings with alternate light and dark, and they are rainbow rings, also called "Newton rings".
will seriously affect people's visual effects

Embodiment 1

[0036] The main layer of the product designed by the present invention is divided into three layers in total, and the main layer (use layer) includes: a hardened coating 11 , a base material 10 , and a rough coating 12 .

[0037] Firstly, a layer of transparent hardened coating 11 is coated on the upper surface of the substrate 10 . The surface hardness of the product treated by the hard coating 11 can reach more than 2H, up to 6H.

[0038] The hardness test is to use a pencil tester to test the surface hardness with a force of 500g. At the same time, the product has a certain anti-friction effect, and the surface of 0000# steel wool has been tested for more than 20 times without obvious scratches.

[0039] Then the lower surface of the substrate 10 is coated with a rough coating 12 with a certain surface roughness, and the rough coating 12 is coated on the lower surface of the substrate 10, so that the lower surface of the substrate 10 has a certain concave-convex effect , ...

Embodiment 2

[0042] In the present invention, different coating treatments are applied on the front and back sides of the base material 10 to achieve a protective film for resisting rainbow rings with a certain anti-scratch performance.

[0043] The inner surface of the transparent film (upper release film 21, lower release film 22) can be selectively coated with an adhesive layer (upper adhesive layer 31, lower adhesive layer 32), or not coated with an adhesive layer. Depends on the product demand. When the adhesive layer (the upper adhesive layer 31 and the lower adhesive layer 32) needs to be coated, silica gel, acrylic glue, pressure-sensitive adhesive, or OCA glue can be used.

[0044] The upper and lower two layers of peeling film (upper peeling film 21, lower peeling film 22) are respectively compounded on the upper and lower sides of the main layer (use layer) by coating the adhesive layer (upper adhesive layer 31, lower adhesive layer 32) Both sides, forming a protective effect. ...

Abstract

The invention discloses a protective film with rainbow ring resistance and a preparation method thereof. The protective film has a rainbow ring eliminating phenomenon, and meanwhile has a certain anti-scraping effect. The protective film comprises a base material, wherein the base material is the basic layer of a main layer, the upper surface of the base material is coated by a transparent hardening coating, the lower surface of the base material is coated by a rough coating with certain surface roughness, the upper surface of the hardening coating is coated by an upper stripping film layer with glue, and the lower surface of the rough coating is coated by a lower stripping film layer with glue. The protective film has a good abrasion resistance effect and is applied to the surface of a protective leather sheath of an electronic product, so that the electronic product has good rainbow ring resistance, and further the visual effect for people in the use process cannot be influenced.

Description

technical field [0001] The present invention relates to an optical protective film, and more particularly to a protective film capable of eliminating rainbow rings in display screens which are often used under different light source conditions. Background technique [0002] Liquid crystal display has the advantages of low energy consumption, light weight, no radiation, and no flicker. It is the mainstream display on the market at present. Now the liquid crystal display technology is very mature. Indispensable product. At the same time, when people use these electronic products, especially smart phones, tablet computers, and notebook computers, they often put a leather case on the electronic product for the protection of the display screen, and put a protective umbrella on the product. However, most of the protective leather cases used in the market now have a layer of transparent PET anti-scratch protective film on the front. Since the protective film is only treated with a...
