Abstract

The invention belongs to the field of electronic product screen protection films and in particular relates to a protection film with a blue-ray-resistant and full-ultraviolet-preventing adhesive layer. In order to endow a conventional scratch-resistant protection film with two new functions of blue ray resistance and ultraviolet shielding, the invention provides the protection film with the blue-ray-resistant and full-ultraviolet-preventing adhesive layer. The protection film with the blue-ray-resistant and full-ultraviolet-preventing adhesive layer consists of a peeling layer, the blue-ray-resistant and full-ultraviolet-preventing adhesive layer, a main film layer and a scratch-resistant coating layer, wherein the scratch-resistant coating layer is arranged on the upper surface of the main film layer; the blue-ray-resistant and full-ultraviolet-preventing adhesive layer is arranged on the lower surface of the main film layer; the peeling layer is arranged on the lower surface of the blue-ray-resistant and full-ultraviolet-preventing adhesive layer. According to the protection film with the blue-ray-resistant and full-ultraviolet-preventing adhesive layer, on the basis that an original function scratch resistance is not destroyed, the protection film is endowed with the two new functions of blue ray resistance and full ultraviolet prevention, the three overall effects of scratch resistance, eye protection and skin aging delaying are achieved for the protection film.

Description

[0001] The invention belongs to the field of screen protective films for electronic products, in particular to a glue layer anti-blue light full anti-ultraviolet protective film. Background technique [0002] With the rapid development of electronic technology, electronic products such as mobile phones, computers, and televisions have almost become necessities for people. People need to spend a lot of time facing these electronic products every day. However, the light emitted by the screens of these electronic products contains harmful Blue light and ultraviolet rays are very harmful to the human body. [0003] Blue light refers to high-energy light with a wavelength of 400-500 nanometers, which can penetrate the lens to reach the retina, causing the retinal pigment epithelial cells to die, resulting in a lack of nutrients for light-sensitive cells, causing irreversible vision damage, and blue light in the air Medium and small particles have a higher chance of scattering and a...
