Embodiment 1

[0042] This embodiment 1 provides a high-transmittance anti-glare and explosion-proof protective film, including a substrate layer, which is sequentially coated with a recoatable anti-glare particle layer, a recoatable low refractive index layer and a non-recoatable layer from the front of the substrate layer upwards. Coat the low-refractive index layer, and coat the optical adhesive layer and the release film layer sequentially from the back of the substrate layer downwards.

[0043] The substrate layer is a TAC transparent substrate with a thickness of 40 μm, and the manufacturer is Fuji, Japan.

[0044] The recoatable anti-glare particle layer is composed of anti-glare particles and UV-curable resin, with a thickness of 3 μm; among them, the anti-glare particles are acrylic (polymethyl methacrylate) particles, specifically FPM-1 provided by Japan Arakawa Chemical ; The UV curing resin is epoxy acrylic resin FPB-6 provided by Arakawa Chemical in Japan.

Embodiment 2

[0062] Embodiment 2 provides a high-transmittance anti-glare and explosion-proof protective film, which differs from Embodiment 1 only in that the thickness of the non-recoatable low-refractive index layer is 110 nm, and the parameters of other components are the same.

[0063] The preparation method of the high-transmittance anti-glare and explosion-proof protective film provided in this embodiment 2 is only different from that of embodiment 1 in that: the preparation of the non-recoatable low-refractive index layer coating liquid in step 3 is: coating SL037 The solution was diluted with propylene glycol methyl ether solvent to obtain a non-recoatable low-refractive index layer coating solution with a solid content of 2.2%, and the rest of the steps were the same.

Embodiment 3

[0065] Embodiment 3 provides a high-transmittance anti-glare and explosion-proof protective film. The only difference from Embodiment 1 is that the thickness of the non-recoatable low refractive index layer is 90 nm, and the parameters of other components are the same.

[0066] The preparation method of the high-transmittance anti-glare and explosion-proof protective film provided in this Example 3 is only different from Example 1 in that: the preparation of the non-recoatable low-refractive index layer coating liquid in Step 3 is: coating SL037 The solution was diluted with propylene glycol methyl ether solvent to obtain a non-recoatable low-refractive index layer coating solution with a solid content of 1.8%, and the rest of the steps were the same.

Abstract

The invention discloses a high-transmittance anti-dazzle explosion-proof protective film and a preparation method thereof, and belongs to the technical field of protective films. The protective film comprises a substrate layer, a recoatable anti-dazzle particle layer, a recoatable low-refractive index layer and a non-recoatable low-refractive index layer sequentially coat the film from the front surface of the substrate layer to the top, and an optical adhesive layer and a release film layer sequentially coat the film from the back surface of the substrate layer to the bottom. The high-transmittance anti-dazzle explosion-proof protective film not only has an excellent anti-dazzle function, but also has ultrahigh transmittance and definition, and also has the functions of protecting a screen against explosion and fingerprints. The product is reasonable in design, simple in preparation process and high in practicability, and can be widely applied to various fields.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to an anti-glare and explosion-proof protective film with high transmittance and a preparation method thereof. Background technique [0002] With the development of information technology, liquid crystal displays have been widely used in smart phones, TVs, computers, vehicle displays and other fields due to their light weight, high-definition picture quality, and low energy consumption. There are many applications. However, during use, due to the superimposition of the light source emitted by the liquid crystal display device itself and the reflected light of the light source in the environment on the display screen, strong glare will be generated, which will cause unclear vision and dizziness after acting on the human eye. Exposure to glare over time can also pose a blindness hazard. In addition, since the current screen is almost made of glass, it will be broken during ...
