Multifunctional assembled protective film

Abstract

The invention discloses a multifunctional assembled protective film. The multifunctional assembled protective film comprises a film substrate layer 1, a film substrate layer 2, a blue-light resistant coating, an anti-scratching layer and an adhesive coating, wherein the blue-light resistant coating coats between the film substrate layer 1 and the film substrate layer 2; the other side of the film substrate layer 1 is coated by the anti-scratching layer; the anti-scratching layer and the other side of the film substrate layer 2 are coated by the adhesive coating; the adhesive coating is laminated with the protective film. The protective film disclosed by the invention has the functions of resisting scratch, resisting water, resisting peep and the like and is capable of preventing the blue light from harming the eyes, preventing the high-energy short-wave blue light from deepening myopia, blocking the blue light and protecting the eye health of the human body.

Description

technical field [0001] The invention relates to a protective film, in particular to a protective film with multiple functions such as anti-scratch and anti-blue light and a preparation method thereof. Background technique [0002] Blue light is an important part of visible light. There is no separate white light in nature itself. When blue light is mixed with green light and yellow light, it presents white light. There is a large amount of irregular short-wave blue light in the visible light emitted by the screens of electronic products such as computers, mobile phones, and digital cameras. The most harmful to the eyes is the high-energy short-wave blue light between 360nm and 500nm. It will directly penetrate the cornea and reach the retina, causing the retina to produce free radicals, which will lead to the decline of retinal pigment epithelial cells, and then make the photosensitive cells lack nutrients, causing vision damage, macular degeneration, squeezing and shrinking...

[0003] However, for modern people, staring at computer screens for a long time is already a kind of civilization that is harmful to the eyes, and after a large number of tablet computers and smart phones are launched, more people become the so-called "head-down people", making staring Eye damage caused by large and small screens has become a more common disease of civilization

[0004] On the other hand, in order to prevent scratches or spray damage on various screens, users often use screen protectors for screen protection, and such screen protectors usually use transparent films, on the one hand, they will not hinder the screen image. On the one hand, it protects the screen from being scratched or sprayed. However, the current screen protectors often only have the function of protecting the screen mentioned above. still not enough
