Problems solved by technology

[0005] With the rapid development of electronic technology, many technical solutions have been proposed to solve the harm of blue light. Anti-blue light screens have become more and more mainstream configurations. However, the current anti-blue light protective film still has poor transparency and absorbs blue light in a narrow wavelength range. Therefore, it is still necessary to study a new type of anti-blue light eye protection terminal screen for children, so as to benefit human eye health

Embodiment 1

[0081] This embodiment provides an anti-blue light eye protection terminal screen protective film for children, denoted as film 1, including:

[0082] Peeling layer: polyethylene terephthalate release film with a thickness of 48 μm;

[0083] Anti-blue light adhesive layer: anti-blue light additives and adhesives, with a thickness of 10.2 μm;

[0084] Substrate layer: polyethylene naphthalate, with a thickness of 120 μm;

[0085] Anti-scratch layer: fatty acid modified polyurethane, inorganic blue light absorber, antistatic agent, with a thickness of 4.8 μm.

[0086] The preparation method of the above-mentioned anti-blue light eye-protecting terminal screen protective film for children specifically includes:

[0087] 1) Preparation of anti-blue light additives:

[0088] Dissolve 3g of 5-aminobenzimidazolone in a mixed solution of 30g of ethanol and water (the mixing weight ratio is 1:1), stir and add 1.7g of 3,5-pyridinedicarboxylic acid under the speed of 400r / min, and con...

Embodiment 2

[0097] Example 2 provides a series of anti-blue light eye protection terminal screen protective films for children, which are respectively recorded as films 2 to 5. The components and preparation methods are basically the same as those in Example 1, except that the anti-blue light used in this implementation The additives are different, as shown in Table 1:

[0098] Table 1 Screen protectors for children’s terminals with anti-blue light and eye protection

[0099]

[0100]

Embodiment 3

[0102] This embodiment provides an anti-blue light eye-protecting terminal screen protective film for children, denoted as Film 6. Its components and preparation method are basically the same as those in Example 1, except that in this implementation, no anti-scratch layer is added Anti-blue light additive.

Abstract

The invention belongs to the technical field of screen protection materials, and particularly relates to an anti-blue-ray eye-protection terminal screen protection film for children. The invention firstly provides an anti-blue-ray auxiliary agent which does not cause color distortion of a display screen while realizing blue-ray adjustment, is safe, non-toxic, high in stability and strong in protective effect, and further provides an anti-blue-ray eye-protection terminal screen protective film for children, which is prepared on the basis of the anti-blue-ray auxiliary agent. The anti-blue-ray eye-protection terminal screen comprises a stripping layer, an anti-blue-light glue layer, a base material layer and an anti-scratch layer; the anti-scratch layer covers the upper surface of the base material layer, the anti-blue-light performance is good, the problems of screen brightness reduction and color distortion cannot be caused, and the anti-blue-ray eye-protection terminal screen is highin hardness, resistant to scratch, good in heat resistance and long in service life.

Description

technical field [0001] The invention belongs to the technical field of screen protection materials, in particular to a terminal screen protection film for children with anti-blue light and eye protection. Background technique [0002] Since human society entered the information age, electronic products such as mobile phones, computers, and televisions have almost become people's necessities. 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 Blue light that is very harmful to the human body. [0003] Blue light refers to high-energy light with a wavelength of 400-500nm. Blue light exposure can cause damage to retinal cells, resulting in myopia, cataracts, macular degeneration, eye pathological hazards and human rhythm hazards. Blue light with a wavelength between 380 and 410 nm is called high-energy blue-violet light, and blue light with a wavelength between 420 and 4...
