Description
Technical field
The present invention relates to glass antidimmer preparing technical field, and in particular to a kind of glass based on primary cellulose acetate
Antifoggant 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.
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

B, primary cellulose acetate dissolves：Primary cellulose acetate is scattered in solvent, heated, until it is all molten
Solution, obtains mixed solution；
C, addition polymerization PAA：Ammonium polyacrylate is well mixed with mixed solution, produced.
A kind of above-mentioned application based on the glass antidimmer of primary cellulose acetate on glass is antifog.
Further, above-mentioned a kind of application based on the glass antidimmer of primary cellulose acetate on glass is antifog, institute
It is vehicle glass to state glass, building glass, bathroom glass, at least one of 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 hydroxyl and glass surface of primary cellulose acetate itself, it is hydrophilic in one layer of glass surface formation
Film, when hydrophilic film runs into water smoke, using its water-wet behavior, water smoke is quickly absorbed, therefore its antifog persistence
Better than the surfactant type (2-3 days) by physical absorption and the antifog time of polymer electrolyte antifoggant (about 15 days), this hair
The bright glass antidimmer based on primary cellulose acetate is antifog for up to 3 months, fully meets the demand of application, while fiber
Plain triacetate will not produce corrosion or other adverse effects to glass, harmless.
