Abstract

The invention provides an anti-blue light protection film having fragrance. The anti-blue light protection film comprises a film protection layer, a usage layer and a stripping layer which are superposed in order, the film protection layer comprises a substrate protection layer and a viscose glue layer which are superposed in order, the usage layer comprises an aromatic hardening layer, a substrate usage layer and an anti-blue light layer which are superposed in order; the stripping layer is a release film; the viscose glue layer and the aromatic hardening layer are adjacently arranged, and the anti-blue light layer and the stripping layer are adjacently arranged. The aromatic hardening layer and the anti-blue light layer are arranged in the usage layer in order by the protection film, so that the protection film has fragrance and has anti-blue light effect.

Description

technical field [0001] The technical field of the mobile phone protective film of the present invention particularly relates to a fragrance-resistant blue light protective film and a preparation method thereof. Background technique [0002] The mobile phone screen has the advantages of low energy consumption, light weight, no radiation, no flicker, etc., and is currently the mainstream display screen on the market. Blue light is an important part of visible light. There are a lot of irregular short-wave blue light in the visible light emitted from 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 between 360nm and 500nm. Blue light will directly penetrate the cornea and cause damage to the retina in the fundus, leading to macular degeneration, especially the blue light in the range of 450nm to 460nm, which is the most harmful to the eyes. Currently, the screens of the most-use...
