Embodiment Construction

[0014] A preparation method of a durable antifogging agent, its raw materials are: sodium phosphate, sodium tripolyphosphate, sodium alginate, fatty acid amine, titanium dioxide, chitosan and deionized water; the weight percentage of each substance is: sodium phosphate 7 ~10%, sodium tripolyphosphate 7~10%, sodium alginate 5~8%, fatty acid amine 2~5%, titanium dioxide 1~3%, chitosan 1~3%, balance deionized water; its characteristics In: its preparation process is as follows:

[0015] 1) Add 20% deionized water into the stirring tank, add sodium phosphate and sodium tripolyphosphate at the same time; stir rapidly for 10-15 minutes, stir until completely dissolved;

[0016] 2) Add fatty acid amine and nano-scale titanium dioxide into the reaction kettle, stir rapidly for 10 minutes, let stand for 10 hours, add 10% deionized water, and stir for 1 hour;

[0017] 3) Add sodium alginate to the reaction kettle, stir evenly, and let stand for 1 to 2 hours;

[0018] 4) Finally, chito...

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

[0001] technical field [0002] The invention relates to a smear agent for reducing the adhesion of water mist to smooth surfaces, in particular to a preparation method of a durable antifogging agent. Background technique [0003] As we all know, in the cold season, due to the effect of temperature and humidity, the surface of the glass will be covered with a layer of mist, such as the window glass of the house, the glass of the car, and the glasses worn by people, which will affect people's life and safety. Bring trouble, even endanger people's life safety. In order to avoid such problems, a lot of research has been done. Anti-fogging agents are generally used at present, but some products are poisonous and have great harm to human body. Contents of the invention [0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a method for preparing an easy-to-use and safe antifogging agent. [0005] In order to achieve the...
