Description
Technical field
The present invention relates to glass antidimmer preparing technical field, and in particular to a kind of glass antidimmer red based on pyrroles and
Its preparation method and application.
Background technology
In daily life, mist causes many troubles to us.Such as：In the winter time, we walk from warm interior
When going out outdoor, glasses bear a piece of fog at once, have obscured our sight；When we prepare to eat reeky food, eye
Mirror also has fog generation, and food is sent toward nose the inside by mistake, causes many embarrassments；Also punch the mirror in cool bathroom afterwards
Son；The camera lens etc. of digital camera, telescope.And have more than 5 degree of difference to winter or rainy season, automobile interior exterior temperature, and
And it is in-car when having abundant steam, humidity higher, glass for vehicle window will haze.Especially windscreen windshield and rearview mirror rise
During mist, mist can have a strong impact on the sight of driver, hinder driving safety.If opening air-conditioning for a long time carrys out dispersing fog, effect is simultaneously failed to understand
It is aobvious, it can also increase many oil consumption plus long-term use of air conditioner dehumidification；Especially driver, should not be in order to remove front screen
Mist and wiped in driving procedure using towel, great safe driving hidden danger be present in this.China's motor traffic accidents in 2015
For more than 30 ten thousand, due to weather reason, traffic accident caused by the visual field is fuzzy accounts for 1/3.
Currently used automobile anti-fogging agent is surfactant type and the class of polymer electrolyte antifoggant two, and the former is lived by surface
Property agent reduce water surface tension so that water smoke glass surface tiling opens, realize preferably anti-fog effect, be market master
Flow, but the antifog time only has 2~3 days；Polymer electrolyte antifoggant is using hydrophilic radical (carboxyl, amido etc.) in macromolecule to water smoke
Absorption realize it is antifog, can be by antifog time lengthening to 15 days because macromolecule filming is good, but anti-fog effect is poor.It is existing
Antifoggant limits its promotion and application exist in terms of anti-fog effect and anti-fog duration the problem of.Need antifog effect badly in market
Fruit is good, the high-performance long-acting antifoggant of antifog time length.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of antifog time to grow, the good glass of anti-fog performance
Glass antifoggant.
A kind of glass antidimmer red based on pyrroles of the present invention, wherein the antifoggant is by following weight percent composition
Composition：Pyrroles red 1~20%, and Sodium Polyacrylate 0.1~5%, surplus is solvent.

Further, above-mentioned a kind of glass antidimmer red based on pyrroles, wherein the antifoggant is by following weight hundred
Divide and formed than composition：Pyrroles red 20%, Sodium Polyacrylate 5%, alcohol 75%.
Further, above-mentioned a kind of glass antidimmer red based on pyrroles, wherein the antifoggant is by following weight hundred
Divide and formed than composition：Pyrroles red 10%, Sodium Polyacrylate 2.5%, ethyl acetate 87.5%.
Above-mentioned a kind of glass antidimmer red based on pyrroles, wherein the red structural formula of the pyrroles is：
Wherein 1≤n≤20000.
Above-mentioned a kind of glass antidimmer red based on pyrroles, wherein the concentration of the Sodium Polyacrylate is 2.5%.
The present invention also provides a kind of preparation method of the glass antidimmer red based on pyrroles.
A kind of preparation method of above-mentioned glass antidimmer red based on pyrroles, it comprises the following steps：
A, material preparation：According to pyrroles is red, the proportioning of Sodium Polyacrylate and solvent, prepare three kinds of raw materials；
B, the red dissolving of pyrroles：It is scattered in pyrroles is red in solvent, heats, until it all dissolves, obtains mixed solution；
C, addition polymerization PAA：Ammonium polyacrylate is well mixed with mixed solution, produced.
A kind of application of the above-mentioned glass antidimmer red based on pyrroles on glass is antifog.
Further, a kind of application of the above-mentioned glass antidimmer red based on pyrroles on glass is antifog, the glass are
At least one of vehicle glass, building glass, bathroom glass, glasses.
The beneficial effects of the invention are as follows：Anti-fog agent for wind-screen of automobile of the present invention is that antifoggant is coated in into glass table
Face, chemical bond is realized by the red amino of itself of pyrroles and glass surface, and one layer of hydrophilic film is formed in glass surface, when
When hydrophilic film runs into water smoke, using its water-wet behavior, water smoke is quickly absorbed, therefore its antifog persistence is better than passing through thing
The surfactant type (2-3 days) of absorption and the antifog time of polymer electrolyte antifoggant (about 15 days) are managed, the present invention is based on pyrroles
Red glass antidimmer is antifog for up to 8 months, fully meets the demand of application, while it is red that pyrroles is red, therefore matches somebody with somebody
Into antifoggant be also red solution, red yet with pyrroles is that monolayer is incorporated on glass, very thin, will not change glass
The color of glass, it will not also change the structure, outward appearance and its performance of glass, it is harmless.
