Description
Technical field：
The present invention relates to a kind of production field of glass, is specifically exactly a kind of preparation method of anti-blue light high transmission glass.
Background technology：
With popularization of the mobile devices such as smart mobile phone in the whole world, the time of consumer's viewing information display screen is significantly increased, because
This, the different degrees of eye illness such as visual impairment, even cataract or blindness occurs in part netizen.There is the important of such case
Reason is injury of the blue light to eyes.Because it is the most frequently used white light synthetic method to excite yellow fluorescent powder with blue chip, and
This white light colour temperature is generally higher, turns into " cold light ".When for a long time in face of various backlight displays such as smart mobile phone or computers,
Eyes will be in the injury of blue ray radiation.When blue light and ultraviolet are to eyes long-term irradiation, neural retina and retina
Pigment epithelial cell can produce serious light injury, and retinal pigment epithelium is more sensitive to blue light, it is easier to by
Blue ray radiation damages, and easily causes macular degeneration, or even trigger blindness.
For the ray radiation injury to eyes such as blue light, researcher utilizes the function of accomplished in many ways glass anti-blue light.
Glass anti-blue light method is roughly divided into interferometric method and absorption process.In interferometric method, multilayer film is plated in glass surface, utilizes multilayer film
Interference performance filter a wavelength range in light.Anti-blue light glass prepared by interferometric method is to rely on any angle incident light,
Therefore can be ended when the light in a wavelength range is impinged perpendicularly on glass, but from the incident light in other directions just not
It can be ended, and it is difficult to obtain precipitous H103 resin to end effect.And absorption process prepare glass bag containing it is light absorbing from
Son, colloid, semiconductive particles etc..Especially, semiconductive particles possess fabulous absorbability, including CdS, CdSe, CdSSe with
And similar cadmium compound.Transmitance of the glass comprising above-mentioned cadmium compound when wavelength is higher than 450nm is higher, and has
Narrower inclination wave-length coverage, thus precipitous absorption curve is easily obtained, this is brighter than the effect that interferometric method anti-blue light obtains
It is aobvious.
Blue light can also be ended by coating process, increase by one layer of anti-blue light coating on the surface of adhering film to glass, can be with
Effectively filter shortwave blue light and harmful ultraviolet so that the light in this section of wavelength can not pass through.Patent
CN201610807137.7 uses magnetron sputtering membrane process, with TiO2And SiO2As deielectric-coating, tool is prepared on a glass substrate
There is the function and service film of cut-off blue light characteristic.The blue light cutoff rate of the glass is up to 98%, more than the spectrum of blue light wavelength
