Abstract
A kind of antifoggant based on indole derivatives, including indole derivatives, assistance agent and solvent, shown in the structural formula such as formula (I) of the indole derivatives.Antifoggant construction proposed by the present invention based on indole derivatives is simple, easy to clean.In construction, it is only necessary to spray antifoggant or coated on glass, the problem of then being wiped with towel or paper handkerchief etc., be rubbed off there is no anti-fog coating in work progress, unlikely occur due to uneven caused glare problem.
Description
Technical field
The present invention relates to a kind of antifoggants, and in particular to a kind of antifoggant based on indole derivatives.
Background technology
Autumn and winter, water mist lead to blurred vision in interior surfaces of glass condensation, the visual field of household and office are influenced, such as in automobile
It is even more to constitute to seriously threaten to vehicle safety travel if glass hazes.China's motor traffic accidents in 2015 is more than 30 ten thousand
It rises, due to weather, traffic accident caused by the visual field is fuzzy accounts for about 1/3.Currently used antifoggant is surfactant type
With two class of polymer electrolyte antifoggant, the former reduces the surface tension of water by surfactant so that water mist is flat in glass surface
It spreads out, realizes preferable anti-fog effect, be the mainstream in market, but the antifog time only has 2~3 days.Existing antifoggant is to skill of constructing
Art is more demanding：It if gently smeared, can cause to smear uneven, glare phenomenon is serious, will will if firmly smeared slightly
Antifoggant is wiped, and anti-fog effect is lost.The above problem existing for existing antifoggant limits its promotion and application.There is an urgent need for anti-in market
Fog effect is good, and the antifog time is long, easy high-performance long-acting antifoggant of constructing.
Invention content
The purpose of the present invention is to provide a kind of antifoggants based on indole derivatives, solve existing for existing antifoggant
Problem, antifog time are up to 4 months or more, and it is extremely simple to construct.
In order to achieve the above-mentioned object of the invention, technical scheme is as follows：
A kind of antifoggant based on indole derivatives, including indole derivatives, assistance agent and solvent, the indoles derive
Shown in the structural formula of object such as formula (I)：
Indole derivatives contain amino, carboxylic group, contain allyl simultaneously.The double bond of allyl can under sunlight
With spontaneous carry out polymerization film formation, the adhesive force of antifoggant is promoted, and then antifog persistence can be promoted.The amino introduced on indoles
There is stronger hydrophily with carboxyl, anti-fog effect can be promoted.Indoles has the stronger ability for absorbing ultraviolet light simultaneously, can
To promote the UV resistance of antifoggant, and then promote the stability of film layer.
It is preferred that the assistance agent is sodium carboxymethylcellulose.The antifoggant based on indole derivatives, use
Assistance agent is sodium carboxymethylcellulose, and this auxiliary agent can prevent antifoggant liquid spontaneous polymerization during storage, is extended
The resting period of antifoggant liquid itself.
When antifoggant is coated on glass, since double bond not yet polymerize at this time, it is very easy to coating uniformly, it will not
There is the problem of glare.It after the completion of construction, irradiates in the sun, double-bond polymerization film forming, antifoggant realizes firm attachment.Due to anti-
Contain a large amount of amino and carboxyl in mist agent, when water mist encounters antifog film, moment is absorbed, and is realized antifog.
It is preferred that the mass concentration of the indole derivatives is 0.1%~18%, the mass concentration of the assistance agent is
0.1%~5%.By experimental test, the content of indole derivatives is 0.1%~18%, and carboxymethylcellulosodium sodium content is
When 0.1%~5%, anti-fog effect is best, can reach 4 months or more, and the duration of 2~3 days than existing antifoggant has
The promotion of matter.
It is preferred that the one kind of the solvent in water, ethyl alcohol, methanol, propyl alcohol, acetone, ethyl acetate and petroleum ether.
In the present invention, the use concentration of the mass concentration of indole derivatives and the equal relative solvent of mass concentration of assistance agent
For.
The present invention also protects the application of the antifoggant based on indole derivatives, is particularly applicable on glass.
The beneficial effects of the invention are as follows：
(1) the anti-fog effect of the present invention is quickly and efficiently.Indole derivatives contain amino, carboxylic group, contain allyl simultaneously
Base, the double bond of allyl under sunlight can spontaneous carry out polymerization film formation, promote the adhesive force of antifoggant, and then can carry
Rise antifog persistence；The amino and carboxyl introduced on indoles has stronger hydrophily, can promote anti-fog effect；Indoles simultaneously
With the stronger ability for absorbing ultraviolet light, the UV resistance of antifoggant can be promoted, and then promote the stability of film layer；?
It is irradiated under sunlight, double-bond polymerization film forming, antifoggant realizes firm attachment.Due to containing a large amount of amino and carboxyl in antifoggant,
When water mist encounters antifog film, moment is absorbed, and is realized antifog.
(2) the present invention antifog time is long.The double bond of allyl under sunlight can spontaneous carry out polymerization film formation, promoted
The adhesive force of antifoggant, and then antifog persistence can be promoted, therefore can be by antifog time lengthening to 4 months or more, than existing
2~3 days duration of antifoggant are improved.
(3) present invention construction is simple, easy to clean.In construction, it is only necessary to spray antifoggant or be coated on glass, so
The problem of being wiped with towel or paper handkerchief etc., being rubbed off there is no anti-fog coating in work progress afterwards, unlikely goes out
Now due to uneven caused glare problem.
In short, the present invention is easy to clean, pollution-free, construction is simple, good antifogging effect, antifog time length (up to 4 months with
On), all more existing antifoggant has qualitative leap on anti-fog duration and construction, solves the defect of existing antifoggant,
It can be promoted in fields such as building, automobiles.
