no. 1 example

[0016] The additive for filtering blue light is added to PET plastic particles, and the PET plastic particles are biaxially stretched to become a polyester film substrate with a thickness of 20-350um, and the addition ratio is 2-150 grams per kilogram of PET particles.

no. 2 example

[0018] The blue light filter additive is added to silica gel (Silica gel chemical formula is mSiO2·nH2O) and coated on PET film or TPU film, and the addition ratio is 5-180 grams per kilogram of silica gel.

[0019] Among them, the formula of the blue light filtering additive is as follows: the addition of antioxidant is 1-5%, the addition of ultraviolet absorber is 10-15%, the addition of hindered amine light stabilizer is 5-8%, and the addition of carbazole-based stilbene 15-30% of the substance, 10-35% of the fluorescent agent, 20-30% of the photochromic agent, and the sum of each component is 100%.

[0020] At the same time, the ingredients are mixed and dissolved in the Hard-coating UV coating or silica gel (Silica gel) to filter the blue light additive, and the temperature range when dissolving is 20-30°C; Stirring: Stir until the material is evenly dispersed, and the concentration of each material in the matrix is ​​controlled. More than 5%; control the temperature of t...

Abstract

The invention relates to the technical field of screen protection, and in particular relates to a screen protection film capable of filtering blue light and a preparation method of the screen protection film. The prepared protection film as a finished product can be used for converting the high-energy shortwave blue light below 400nm into blue-green light above 410nm to 580nm, thereby filtering the blue light which is in a wave band within 380nm to 480nm and harmful to eyes. The protection film is capable of absorbing the ultraviolet rays and the blue light of sunlight with the wave length within 380nm to 400nm under sunshine, so that the protection film can glow blue or green. The protection film is suitable for the screens of mobile phones, tablet computers, displays and televisions. The protection film is also suitable for the fields of the film pasting of automobiles, the film pasting of building doors and windows in a blue light filtering manner and the like. Thus, the protection film provided by the invention is worthy of being further applied and popularized.

Description

technical field [0001] The invention relates to the technical field of screen protection, in particular to a screen protection film capable of filtering blue light and a preparation method thereof. Background technique [0002] With the advancement of science and technology, LED electronic screens are very popular in the market now. They usually emit high-energy short-wave blue light. Cellular necrosis of the lens, and macular degeneration or cataracts. [0003] In addition, using such products for a long time will cause visual fatigue, tension of eye muscles and lenses, and deepening of myopia, which will affect people's health. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a screen protective film that can filter blue light and its preparation method, which can not only filter out all wavelengths of ultraviolet rays but also filter or convert most of the higher-energy violet-blue ligh...
