Background technology
Along with the fast development of electronics technology product, the electronic product such as panel computer, notebook, mobile phone becomes us especially
Live an indispensable part.Working clan, race of bowing, game enthusiasts become the important promotion that electronics technology develops especially
Person.But, we are while enjoying because of the joyful sense of the development in science and technology thing followed, and visual problems is also at convexity unconsciously
Aobvious.The a large amount of irregular shortwave blue light that the appearance of the symptoms such as eye is dry, puckery, the visual deterioration of eye and electronic product screen send has
Close association.Blue light is at visible ray medium wavelength closest to ultraviolet, and its wave-length coverage is 360nm～500nm.This wave band
Blue light can be directed through cornea, the retina of intraccular part is caused directly damage, causes macular disease, thus increase
Visual deterioration or blind disease send out probability.Thus, how to reduce the blue light injury to human body vision, it has also become glasses,
Electronic curtain, screen protecting film industry need the social problem of solution badly.
In order to preferably reduce the injury that human eye is brought by blue light, many professional persons be devoted to study blue light absorption or
Person's filtering material, such as plastics filter, can filter the blue light of specific wavelength, ultraviolet light to a certain extent.Prior art
In have by by yellow UV absorbent (methacrylic acid azobenzene ester) or 2-(2-hydroxyl-5-isopropyl olefin(e) acid ethoxycarbonyl benzene
Base)-2H-benzotriazole as raw material add in contact lens be polymerized；At 380nm～450nm, absorption is had additionally, also have
Azo compound as blue-light absorbers, but can also still suffer from poorly water-soluble, addition is restricted mostly, thus shadow
Ring the carrying out of subsequent step, additionally, there may be during use the shortcomings such as effective ingredient easily loss.
Summary of the invention
Goal of the invention: it is an object of the invention to provide the high temperature resistant blue-light absorbers of specific absorption wavelength, specific absorption
Wavelength is at 400nm～465nm, preferably solves blue light and closes threat and the blue-light absorbers of human eyesight at glasses, protecting film
It is difficult to a difficult problem for Effective Doping during one-tenth, the aspects such as glasses, screen protecting film, electronic curtain can be effectively applied to, can
To reduce greatly the damage to eyes of the blue light of varying strength；It is a further object of the present invention to provide the resistance to of specific absorption wavelength
The preparation method of high temperature blue-light absorbers.
Technical scheme: for achieving the above object, the present invention adopts the following technical scheme that
The high temperature resistant blue-light absorbers of specific absorption wavelength, its general structure such as formula (I):
Wherein, R is-H or-CH3。
Described formula (I) is synthesized by following chemical equation (II):
The preparation method of the novel fire resistant blue-light absorbers of described specific absorption wavelength, comprises the following steps:
1) it is that 1:2:10 claims according to phthalic anhydride, 2-methylquinoline or 2,6-dimethyl quinoline, zinc chloride mol ratio
Take raw material 1:2:10 in reaction bulb, fully dissolve after mixing, obtain mixture；
2) mixture is put in microwave oven react, after the solution in question response bottle generates faint yellow solid, stop
Microwave heating, adds solvent so that it is after fully dissolving, and carries out sucking filtration, removes unreacted material, repeat with solvent molten afterwards
Solve sucking filtration 2～3 times, obtain end product；
3) end product is placed in vacuum drying oven and overnight dries the novel fire resistant blue light obtaining specific absorption wavelength
Absorbent.
Step 2) in, described microwave oven peak power is 600W, and applying power is 50%, and the response time is 5-8 minute,
Reaction temperature is up to 180 DEG C.
Step 2) described in solvent selected from dehydrated alcohol, methanol, ethyl acetate, petroleum ether and dichloromethane.
Step 3) in, described vacuum drying oven temperature is 60～180 DEG C.
Beneficial effect: compared with prior art, the high temperature resistant blue-light absorbers of the specific absorption wavelength of the present invention, more
Organic solvent in all have certain dissolubility, it is possible in glasses, screen protecting film production process, carry out Effective Doping, resistance to height
The characteristic of temperature further increases the advantage of itself, such that it is able to arriving in more industry is applied.The preparation of the present invention
Method is low for equipment requirements, and operating process is simple, only can settle this material of generation at one go by the method for microwave heating, it is easy to
Operation and popularization, possess good practicality.
Accompanying drawing explanation
Fig. 1 is for be dissolved in blue-light absorbers in different organic solvents so that it is concentration is 10-5Mg/mL, at 350nm～
Uv absorption figure at 650nm；
Fig. 2 is blue-light absorbers uv absorption figure at 350nm～500nm.
Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, it is further elucidated with the present invention.
The high temperature resistant blue-light absorbers of specific absorption wavelength, its general structure such as formula (I):
Wherein, R is-H or-CH3。
Formula (I) is synthesized by following chemical equation (II):
The preparation method of the novel fire resistant blue-light absorbers of specific absorption wavelength, comprises the following steps:
1) chemical raw material weighs: 7.4g phthalic anhydride, 13.2mL 2-methylquinoline or (2,6-dimethyl quinoline
Quinoline), and 0.34g zinc chloride three is as in 100mL single necked round bottom flask, is mutually mixed and fully dissolves, wherein reactant
Mol ratio be phthalic anhydride: 2-methylquinoline or 2,6-dimethyl quinoline: zinc chloride=1:2:10；
2) selection of reaction condition: after above-mentioned solution fully dissolves, then that mixture is anti-as carrying out in microwave oven
Should (peak power 600W applies power and is up to 50%) be 5～8 minutes, during this, reaction temperature may be up to 180 DEG C；
3) process of product: after the solution in question response bottle generates faint yellow solid, stops microwave heating, adds nothing
Water-ethanol so that it is after fully dissolving, and carry out sucking filtration, removes unreacted material, repeats to dissolve sucking filtration 2 with dehydrated alcohol afterwards
～3 times；
4) final product is placed in vacuum drying oven at 60 DEG C～180 DEG C, overnight dries.
The final blue-light absorbers obtained is dissolved among different organic solvents, such as hexamethylene, N, N-dimethyl formyl
In the solvent that amine etc. must be used in spectacles industry or screen protecting film building-up process, there is preferable dissolubility, explanation
This blue-light absorbers can preferably be entrained among glasses or screen protecting film, and from Fig. 1-2, this blue light absorption
Agent has preferable uv absorption at 400nm～465nm, and does not affect the absorption of useful blue light at 470nm～490nm, it is sufficient to
Reach to protect the effect of vision.It addition, this blue-light absorbers be enough to bear the high temperature of 180 DEG C so that it is be suitable in more industry
Promote.
