Abstract

The invention relates to an anti-scratch eye-protecting screen protective film. The screen protective film comprises an anti-scratch polyethylene terephthalate (PET) substrate layer, a first OCA optical polyacrylic adhesive layer, a first optical-grade PET substrate layer, a second OCA optical polyacrylic adhesive layer, a second optical-grade PET substrate layer and an anti-static layer which aresequentially attached, wherein the PET base material layer material comprises: 80-85 wt% of polyester resin, 10-15 wt% of chlorinated polypropylene and 2-8 wt% of a wear-resistant assistant, and thewear-resistant assistant comprises perfluorinated ethylene propylene, hydrophobic fumed silica and sodium stearate with a ratio of 3:(1-2):1. According to the anti-scratch eye-protecting screen protective film disclosed by the invention, through the change of components and proportions of the PET substrate layers, the overall wear-resistant and scratch-resistant performance of the protective filmare effectively improved. A blue-ray resistant agent and an auxiliary agent are added to the first OCA optical-grade polyacrylic adhesive layer and the second OCA optical polyacrylic adhesive layer, so that the overall blue-ray resistant performance of the protective film is effectively improved.

Description

Technical field [0001] The invention belongs to the technical field of films, and specifically relates to a scratch-resistant eye-protecting screen protective film. Background technique [0002] Blue light can be seen everywhere in daily life, but the main source of harmful blue light is the LED LCD screen. Today's LCD screens are all LED backlights. Since the backlight requires the effect of white light, the industry uses blue LEDs mixed with yellow phosphors to form white light. Since the blue LED is a main body hardware, the blue spectrum of this white light has a peak, which causes what we call the problem of harmful blue light hurting the eyes. [0003] Studies have shown that blue light accelerates the oxidation of cells in the macular area of ​​the retina, damages visual cells, increases the risk of macular degeneration, reduces vision, and may even cause permanent damage to vision. The mobile phone screen will produce harmful light mainly blue. [0004] With the developme...
