And the existing marginally blue light of filter 23 80nm-450nm wave band of screen sticking film of pasting on device display that produces at number cannot filter harmful blue light of the 400nm-500nm wave band of more wide scope.
Utility model content
The utility model provides a kind of screen sticking film, its more high efficiency or filter more broadly that digital product display screen sends to the great blue light of eye injury, realize and intercept blue light, the upper phototoxicity of reduction is to the full extent the strongest and cause the blue wave band of having a sleepless night, and reduces the injury of blue light to eyes.
For achieving the above object, the utility model adopts following technical scheme: a kind of screen sticking film, it comprises that the silicone protective layer that sets gradually from top to bottom, blue light barrier layer that PETG is done substrate, substrate layer that PETG is made material and PETG make the release protective layer of material, between described substrate layer and release protective layer, sets firmly by a silica gel layer;
Further, in described blue light barrier layer, contain resistance photoion, described resistance photoion is metal ion;
Further, described blue light barrier layer is the nano coating that contains the anti-fingerprint nano paint being combined by fluorin radical and silicon group, and it is transparent crystallization film plating layer;
Further, the thickness of described silicone protective layer is 40 μ m-60 μ m;
Further, the thickness of described blue light barrier layer is 4 μ m-7 μ m;
Further, the thickness of described substrate layer is 90 μ m-110 μ m;
Further, the thickness of described release protective layer is 30 μ m-50 μ m;
Further, the thickness of described silica gel layer is 30 μ m-50 μ m.
Adopt after technique scheme, screen sticking film provided by the utility model, because introducing blue light barrier layer, by filtering out the blue light of more than 99% 320nm-400nm wave band, and filtering out 60% 415nm-455nm and the blue light of two wave bands of 465nm-495nm, i.e. effective filtering noxious blue light, reduces light poison the strongest and cause the blue wave band of insomnia to the full extent, thereby protection eyes are not endangered by blue light, and can effectively prevent from promoting sleep because of the insomnia that blue light causes; Simultaneously because the composite construction of this screen sticking film makes it have the light transmittance up to 90%, and it is without rainbow line, plays scratch resistant, anti-fingerprint, effectively protect the effect of screen.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
Described in figure 1; a kind of screen sticking film that the utility model provides, it comprises that the silicone protective layer 1 that sets gradually from top to bottom, blue light barrier layer 2 that PETG is done substrate, substrate layer 3, silica gel layer 4 and PETG that PETG is made material make the release protective layer 5 of material.Wherein substrate layer 3 sets firmly by silica gel layer 4 with release protective layer 5.
The thickness of silicone protective layer 1 is 40 μ m-60 μ m, and it has good toughness and elasticity, is not easy because of external force permanent deformation.Silicone protective layer 1, as the top layer of screen sticking film, can be protected not sensitive for damages of whole screen sticking film, and its material is touching the surface of screen sticking film can be smooth to the touch.
The thickness of blue light barrier layer 2 is 4 μ m-7 μ m.Blue light barrier layer 2 is to make nano coating substrate and that contain anti-fingerprint oil nano paint with PETG, it is transparent crystallization film plating layer, described anti-fingerprint oil nano paint is to be combined by fluorin radical and silicon group, it is through cure process, can improve hardness, toughness, glossiness, the water-sprinkling of lacquer painting, and allow screen sticking film can prevent that display screen is subject to the injury of scratch and fingerprint oil.
In blue light barrier layer 2, contain resistance photoion, this resistance photoion is a metal ion species.The metal ion coating of blue light barrier layer 2 can intercept the light of 400nm-500nm wavelength, thereby reaches the effect of the anti-myopia of anti-blue light.Described metal ion can intelligently intercept the light in 400nm-500nm wave band, and other light that is greater than or less than this wave band all can be let pass, make like this screen sticking film not only reach the effect of anti-blue light, and can also accomplish effectively to keep a good light transmittance, can reach 90%.
The thickness of substrate layer 3 is 90 μ m-110 μ m, and material is PETG, and light transmission is more than 90%.
The thickness of silica gel layer 4 is 30 μ m-50 μ m, connects substrate layer 3 and release protective layer 5 for pasting.Wherein, the silica gel of silica gel layer 4 has the series of advantages such as automatic vent is fast, excellent adsorption, light transmittance is high, temperature tolerance good, long service life, environmental protection.
The thickness of release protective layer 5 is 30 μ m-50 μ m, is positioned at the orlop of screen sticking film, and as the contact layer of screen sticking film and display, its material is PETG.Release protective layer 5 has that transparency is high, nonpoisonous and tasteless, tensile strength is large, deflection is good, anti-ly hardening crack, not cracky, electric and excellent optical performance, resistance oxygen and hinder moist good, cold-resistant (70 DEG C), heat-resisting (+200 DEG C), the good characteristic such as corrosion-resistant, shrinkage is stable.
The silica gel with automatic absorbing of silica gel layer 4 is critically coated on substrate layer 3 through high-tech, more release protective layer 5 is close to the another side of silica gel, and substrate layer 3 is just pasted together with release protective layer 5.
In the manufacturing process of screen sticking film, silicone protective layer is processed and ensures that each even film layer is smooth through frosted, and therefore screen sticking film there will not be rainbow line.
The screen sticking film that observation Fig. 2 the present embodiment detects is known to the rejection rate of 350nm-800nm band of light, its screen sticking film of the present utility model is 20%-80% to the blue light wavelength section rejection rate of 380nm-450nm, the rejection rate of the blue light wavelength section to 470nm-500nm reaches more than 80%, and the blue light of 470nm-500nm wavelength period can reduce the secretion of human body melatonin, thereby make people's mental excitation, have difficulty in going to sleep, therefore this screen sticking film can effectively prevent from improving sleep quality because of the insomnia that blue light causes.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
