Description
Technical field
The invention belongs to anti-blue light technical field, and in particular to anti-blue light resin combination, cured film and preparation method, guarantor
Cuticula.
Background technology
Blue light is the important component of visible ray, and in itself without single white light, blue light is mixed nature with green glow, gold-tinted
White light is showed after conjunction.Blue light is stronger near the part of ultraviolet, energy in visible ray, and wavelength is between 380-500nm.
Because wavelength is shorter, the through retina of crystalline can be penetrated.Blue light easily causes visual fatigue and macula retinae portion disease.It is yellow
Spot portion lesion is irreversible process, ultimately results in visual impairment even as blind as a bat.Other blue light can stimulate brain, suppress to take off
Melanocyte is secreted and improves the generation of corticoid and directly affects sleep quality so as to destroy hormone secretion balance.
Under field conditions (factors), the lesion of macula area is slower.With developing rapidly for electronics technology, increasing people
Using electronic products such as computer, mobile phone, digital cameras, daily life is even more too busy to get away electronic product.Electronic product is glimmering
Containing substantial amounts of irregular blue light and ultraviolet in the light that screen sends.
For this kind of situation, anti-blue light diaphragm arises at the historic moment, and such as Chinese invention patent CN105086570A discloses one
Kind《Intercept blue light hardening resin and intercept blue light cured film and manufacture method》, embodiment discloses the hardening resin by propylene
Acid resin, isobornyl methacrylate monomer, hydroxyethyl methacrylate, hydroxy propyl methacrylate, azo complexing
Dyestuff, and polymerization initiator is mixed, by hardening resin add filter blue light dyestuff (azo complex dyestuff),
Make it have the performance for intercepting blue light.
But the ultraviolet of electronics fluorescent screen residual can also be damaged to human body, and ultraviolet in external environment condition can be caused
Display screen is aging and xanthochromia, and the invention can not effectively be absorbed to ultraviolet, so anti-blue light antiultraviolet diaphragm
Exploitation is even more important.
And such anti-blue light cured film of commercial type is mostly hard by coating on base material film anti-blue light successively at present
Change coating and ultraviolet-proof to realize, such as patent CN103935097B is disclosed《A kind of anti-blue light cured film》, in basement membrane
Side anti-blue light hardening coat and ultraviolet-proof is set gradually to absorb ultraviolet and blue light, its operation is more, cost
It is high.And in the antiultraviolet masking liquid of the invention, acrylic resin is only used as solidified resin, need to it is possible to additionally incorporate ultraviolet
Screener intercepts ultraviolet, high cost.
The content of the invention
