Abstract
The invention relates to a coat capable of reducing adhesion of water mist to a smooth object, and in particular relates to a preparation method of a persistent antifogging agent, wherein the raw materials of the persistent antifogging agent include sodium phosphate, sodium tripolyphosphate, sodium alginate, fatty acid ammonia, titanium dioxide, chitosan and deionized water; the sodium phosphate and the sodium tripolyphosphate are taken as the dispersant, while the fatty acid ammonia is taken as the emulsifier, and the sodium alginate and the chitosan are added so that the persistent antifogging agent has excellent hydrophily and antifogging function; in the meantime, the hydrophilic nanoscale titanium dioxide is added to prolong the antifogging time and improve the antifogging effect; no substance harmful on the human body is added so that the persistent antifogging agent is harmless to the human body.
Description
Technical field
The present invention relates to a kind of basting agent of water smoke to smooth adhesion that reduce, specifically relate to a kind of preparation method of persistent form antifogging agent.
Background technology
As everyone knows, the effect in cold season due to temperature and humidity, fumulus can be coverd with in the surface of glass, as the window glass in house, vehicle glass, the glasses that people wear in addition etc., these make troubles to people's life and safety, even endanger people's life security.For fear of such problem, people have carried out a large amount of research.What generally use at present is antifogging agent, but the product having is poisonous, and the person is had to very large injury.
Summary of the invention
In view of the problem that prior art exists, the object of the invention is to provide a kind of preparation method of antifogging agent easy to use, safe.
To achieve these goals, the technical solution adopted in the present invention is a kind of preparation method of persistent form antifogging agent, and its raw material is: sodium phosphate, tripoly phosphate sodium STPP, sodium alginate, fatty acid amine, titanium dioxide, chitosan and deionized water; The weight percent of each material is: sodium phosphate 7 ~ 10%, tripoly phosphate sodium STPP 7 ~ 10%, sodium alginate 5 ~ 8%, fatty acid amine 2 ~ 5%, titanium dioxide 1 ~ 3%, chitosan 1 ~ 3%, surplus deionized water; It is characterized in that: its preparation process is as follows:
1) 20% deionized water is added in stirring tank, add sodium phosphate and tripoly phosphate sodium STPP simultaneously; Rapid stirring 10 ~ 15 minutes, is stirred to and dissolves completely;
2) in reactor, add fatty acid amine and Nano titanium dioxide, rapid stirring 10 minutes, standing 10 hours, at the deionized water that adds 10%, stirs 1 hour;
3) in reactor, add sodium alginate, stir, standing 1 ~ 2 hour;
4) finally add chitosan, add the deionized water of surplus, stir latter standing 2 hours, make finished product.
The weight percent of described each material is preferably: sodium phosphate 8, tripoly phosphate sodium STPP 8, sodium alginate 6, fatty acid amine 3, titanium dioxide 2, chitosan 2 and deionized water 71.
The weight ratio of described sodium phosphate and tripoly phosphate sodium STPP is 1:1.
Described titanium dioxide is the titanium dioxide of nano level doped F.
The invention has the advantages that: adopting sodium phosphate and tripoly phosphate sodium STPP is dispersion agent, fatty acid amine is emulsifying agent, and add sodium alginate and chitosan, make it have good wetting ability and anti-fog function, add the Nano titanium dioxide with hydrophilicity simultaneously, can extend the antifog time, improve anti-fog effect; And do not add harmful material, can not work the mischief to human body.
