Description
Technical field
This utility model relates to a kind of anti-blue light and antifog protecting film, is particularly suitable for being pasted onto the glass surface of the glass surface of building or automobile.
Background technology
Blue light be wavelength be the high-energy visible ray of 380～500nm, wherein the shortwave blue light of 380～440nm can stimulate retina to make it excite radical ion to cause retinal pigment epithelium atrophy, cause the death of photosensitive cell again, finally causing the dimness of vision, vision is gradually reduced and even completely loses.Blue light injects optical fundus after over-focusing, and focus does not falls within retina, but falls between retina and crystalline lens, which increases the aberration distance that light focuses within the eye.Injecting of blue light can aggravate aberration and dimness of vision degree, then eye muscle hypertonicity, eye blood supply hypertonicity, and ocular blood supply is strengthened, thus increases the weight of fatigue；Blue light also can increase the weight of macula retinae district disease, and after exposure for a long time, the shortening along with wavelength is increased by amphiblestroid toxicity, thus increases the weight of macular area disease.
Building or automobile have the substantial amounts of glass structure for transmitted light, and glass or glass fenestrated membrane currently on the market does not all have good anti-blue light effect.Owing to the light source of sunlight and headlight for vehicles all also existing substantial amounts of high energy shortwave blue light, therefore in this case, for a long time by blue ray radiation, the eyes of meeting harm people, and then cause eye vision impairment and be difficult to recover.Therefore, it is badly in need of developing the protecting film that a kind of anti-blue light is effective, in order to effectively protection human eye health is not injured by blue light, has again antifog effect.
Summary of the invention
The purpose of this utility model is: provide a kind of blue light that can efficiently intercept to have again the anti-blue light of anti-fog effect and antifog protecting film.
The technical scheme realizing this utility model purpose is: a kind of anti-blue light and antifog protecting film, and its innovative point is,
It is by anti-fog layer, first polyester film, anti-blue light substratum transparent, second polyester film, pressure-sensitive adhesive layer and mould release membrance is constituted and each layer is complex as a whole；Described anti-fog layer ultraviolet light polymerization is combined on a surface of first polyester film, anti-blue light substratum transparent heat cure is combined on another surface of first polyester film, one surface recombination of second polyester film is at the outer surface of anti-blue light substratum transparent, pressure-sensitive adhesive layer heat cure is combined on another surface of second polyester film, and mould release membrance is compounded in the outer surface of pressure-sensitive adhesive layer.
In technique scheme, first described polyester film and second polyester film are all transparent polyester films, or are all dyeing polyester films or are all primary colors polyester film, or are all ultraviolet-resistant polyester films, or it is all aluminized polyester film, or is all magnetron sputtering polyester film；Or described first polyester film and second polyester film are the polyester films of different cultivars.
