[0043] Please refer to FIG. 3 , a method for preparing a screen protective film 100 according to an embodiment includes the following steps:

[0044] S10. Coating a mixture of inorganic nanoparticles and solvent-based paint on one surface of the main film layer 140, followed by drying at 50°C to 100°C and curing with ultraviolet light to form an anti-glare layer 130, wherein the inorganic nanoparticles and solvent-based paint The coating mass ratio is 1-20:100.

[0045] The light transmittance of the main film layer 140 reaches above 80%. The haze of the main film layer 140 is less than 5%. The thickness of the main film layer 140 is uniform.

[0046] The antiglare layer 130 may have a thickness of 2 μm˜10 μm. The inorganic nanoparticles can be nano-silica or nano-alumina. It can be understood that the inorganic nanoparticles can also be other materials. The particle size of the inorganic nanoparticles may be 10 nm to 150 nm. Solvent based coatings can be urethane acryla...

Embodiment 1

[0072] A mixture of nano-silica and urethane acrylate is coated on one surface of the main film layer, wherein the mass ratio of nano-silica and urethane acrylate is 1:100, and then cured with ultraviolet light after drying at 50°C to form Anti-glare layer. The material of the main film layer is PET. The thickness of the main film layer is 50 μm. The light transmittance of the main film layer is 92%, and the haze is 1.3%. The antiglare layer formed had a thickness of 5 μm. The particle size of the nano silicon dioxide can be 10nm.

[0073] The other surface of the main film layer is coated with solvent-based acrylic and Cu by knife coating. 2+ Doped Ba 7 Si 2 o 7 Br 8 The mixture is then dried at 120°C to form an anti-blue light adhesive layer. Solventborne Acrylic and Cu 2+ Doped Ba 7 Si 2 o 7 Br 8 In the mixture, Cu 2+ Doped Ba 7 Si 2 o 7 Br 8 The mass percentage is 2%.

Abstract

The invention discloses a screen protection film which comprises an anti-dazzling layer, a main film layer and an anti-blue light glue layer which are sequentially overlapped, wherein the anti-dazzling layer is formed by curing a mixture of an inorganic nanometer particle and a solvent coating, with a weight ratio of (1-20):100. According to the screen protection film, through arranging the anti-dazzling layer on the surface of the main film layer, the anti-dazzling layer is formed by curing the mixture of the inorganic nanometer particle and the solvent coating, and the inorganic nanometer particle is doped in the solvent coating, so that a certain concave-convex effect is achieved on the surface of the anti-dazzling layer, and light rays scattered by the surface of the anti-dazzling layer are increased to cause the effect that the glossness is reduced, thus an image of a display screen is thinned, the anti-dazzling effect is achieved, the vision comfort degree is improved, and the hurt of the display screen to eyes is reduced. In addition, the invention further provides a preparation method of the screen protection film.

Description

technical field [0001] The invention relates to the field of display devices, in particular to a screen protective film and a preparation method thereof. Background technique [0002] With the application of capacitive screen technology more and more widely, display screens are becoming more and more common in people's daily life, and people cannot live without display screens. When people face the display screen for a long time, some defects and side effects of the display screen itself become more and more obvious. Since the liquid crystal display is a kind of display that cannot emit light automatically, the visual recognition of this kind of display will be significantly damaged when external light is reflected on the display surface, and the image is even more difficult to recognize when it is operated under high-brightness light. Watching this kind of screen for a long time will cause great damage to people's eyes and easily make people tired. Therefore, as people's r...
