Problems solved by technology

2. Lead to macular degeneration, which gradually becomes cloudy and forms cataracts. Most of the blue light will penetrate the lens, especially for children. The lens is relatively clear and cannot effectively resist blue light, which makes it easier to cause macular degeneration and cataracts
3. It is easy to cause visual fatigue
4. Affect sleep
However, the product has white edges and yellowing at the bends, which is prone to scratches, and its anti-blue light effect cannot meet the demand.

preparation example Construction

[0033] The preparation method of the self-repairing material is as follows: the raw materials are dispersed and polymerized in a high-pressure reactor.

[0034] Specifically, the preparation method of the self-healing material is: mix the main raw materials and solvents except additives in a high-pressure reactor, stir for 15 minutes, slowly add cross-linking agents, catalysts and other additives and stir for 10 minutes, and then use vacuum pumping Principle The large amount of air bubbles generated during the stirring process in the coating solution is sucked away, and then left to defoam for 20 minutes to obtain a self-healing material. At this time, the self-healing material can be directly coated on the substrate 10 . This preparation method greatly reduces undesirable phenomena such as uneven coating surface and concave-convex points caused by the influence of bubbles in the coating liquid on coating, significantly improves the appearance of the coating, and can greatly im...

Abstract

The invention discloses a curved screen protective film. The curved screen protective film comprises a base material, and a self-repairing layer and a blue-light-proof layer which are respectively connected with two opposite surfaces of the base material, wherein the base material is one of a TPU base material, a PVC base material, a PP base material and an EVA base material; wherein the self-repairing layer is formed by coating with a self-repairing material, and the blue-light-proof layer is formed by coating with a blue light preventing material; the self-repairing material is prepared fromthe following components in parts by weight: nano silicon dioxide, ester substances, silicate, nano calcium, a solvent and an auxiliary agent, the blue-light-proof layer is prepared from the following components in parts by weight: azophenyl methacrylate, ethyl isoacrylate phenyl 2H-benzotriazole, an azo compound, a solvent and an auxiliary agent. The curved screen protective film is good in bluelight prevention effect, can prevent white edges and yellow edges, and can be attached to a wide screen.

Description

technical field [0001] The invention relates to the technical field of protective films for electronic products, in particular to a protective film for curved screens. Background technique [0002] With the rapid development of electronic products, electronic products such as tablets, notebooks, and mobile phones have become an indispensable part of our lives. In the current mobile phone screen and various electronic display markets, touch 2.5D and 3D curved glass screens have become the mainstream. Taking iPhone8, Samsung Galaxy, Huawei, and OPPO as precedents, batches of curved glass screens of different degrees have broken consumers' aesthetics for straight touch screens. Fatigue has also become the mainstream of product innovation and touch screen market of major brands in the future. [0003] However, while we are enjoying the pleasure of life that comes with the development of technology, vision problems are also unknowingly highlighted. Symptoms such as dry eyes, ey...
