Description
Technical field
The invention belongs to light absorbing material technical fields, and in particular to have in 280-450nm spectral regions to different wave length
Optical material of specific absorption and preparation method thereof.
Background technique
It is well known that ultraviolet light can injure the eyes of people, in addition, the blue light in visible light can also damage eyes.
The a part of blue light as visible light has high energy, and wave-length coverage is between 400~500nm, with computer, mobile phone,
The electronic products such as ipad it is widely available, non-natural light based on blue light will generate irreversible injury to human eye, make
It is dry and astringent at human eye, tired, shed tears, myopia accelerate, macular area disease the problems such as.According to the end of the year 2009 of the World Health Organization (WHO)
Issue orange warning: blue light will be considerably beyond tonyred, melamine, the destruction of SARS etc. to potential stealthy threaten of the mankind
Property, at least 30000 people blind because of the radiation of blue light every year.Existing photochromic optical material is in optics tree mostly
Off-color material is added in rouge, preparation process is " base is anti-" technique, these materials (bright environment) in solar radiation can obstruct
The injury of ultraviolet light and strong light, but blue light cannot be obstructed at dark environment (interior), that is, change colour not anti-blue light；Human eye is to 400-
440nm range blue light depending on object and distinguishing that color is insensitive, and the wave band optical wavelength is short, energy is high, big to eye injury, for nocuousness
Blue light, optical material (device) should keep low transmission to this some blue light；440-500nm range is middle long wave blue light, to people
Eye injury is relatively small, can help pupil contraction, show the color of object, to ensure that view object picture is true beneficial to blue light
In the case where, certain transmitance is kept to this some blue light.External blue light protective materials mostly uses greatly coating technique, preparation
Technique is " film anti-" technique, i.e., absorbs blue light by blue light protecting film, and overall blue light effective percentage can only achieve 17% or so, and
The protection of short, medium and long blue spectral region cannot distinguish between；In addition, under bright environment (daylight) to obstruct strong light more difficult, human eye by
Light irradiation injury is big, i.e., anti-blue light is non-discolouring.
For from preparation process, existing photochromic " base is anti-" technique can not be simultaneous with anti-blue light " film is anti-" process matching
Hold, this is because surface blue Light Film absorbs a large amount of ultraviolet lights, so that the ultraviolet light entered in optical material matrix is reduced, and
The excitation for lacking ultraviolet light significantly reduces photochromic efficiency.Optical material technology future developing trend is the more function of development
Energy integration technology, simple function have been unable to meet the following people to integrated, the intelligent requirements of optical material and device.Cause
This, needs to absorb to spectrum line, develops high-performance intelligent optical material technology and technique, can be according to light intensity
Automatically adjust transmitance, by selectivity through beneficial to light and cut-off harmful light, realize light and shade is controllable, on-demand light transmission have it is great
Meaning.
Summary of the invention
The object of the present invention is to provide difunctional coated optical materials of a kind of anti-blue light/discoloration and preparation method thereof.Wherein
Polyurethane/light absorber/TiOx nano complex microsphere is adulterated in anti-blue light coating.The composite nano-microsphere kernel is repaired for surface
The Titanium dioxide nanoparticle of light absorber is adornd, shell cladding polyurethanes simultaneously forms compound core-shell structure.The material block
Spectral region is extended to blue spectrum area from ultraviolet spectra area, in the case where keeping high transmittance, has to different-waveband indigo plant
Light distinguishes the performance of absorption, and wherein 280-380nm ultraviolet ray transmissivity is less than 1%, 400-440nm shortwave blue light transmitance
It is more than 50% lower than 5%, 460-500nm spectral regions blue light transmitance；The anti-blue light material can with photochromic coating material into
Row matching and function are integrated, can automatically adjust transmitance according to light intensity, by selectivity through harmful beneficial to light and cut-off
