Embodiment Construction

[0014] A glass anti-fogging agent, the weight percentage of each material of its raw material is sodium phosphate 2~4%, sodium tripolyphosphate 2~4%, copolyethylene 1~3%, polyethylene glycol 3~5%, isopropylene glycol 0.5% ~2%, fatty acid amine 3~6%, lauryl polyoxyethylene ether 1~2% and deionized water; the steps are:

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

[0016] 2) Add fatty acid amine and polyoxyethylene lauryl ether into the reaction kettle, stir for 30 minutes, let stand for 1~2 hours, and stir for 30 minutes;

[0017] 3) Add polyethylene copolymer to the reactor, stir evenly, and let stand for 1~2 hours;

[0018] 4) Add polyethylene glycol into the reactor, and stir until the polyethylene glycol is fully mixed with the solution in the reactor;

[0019] 5) Finally, add isopropylene glycol, stir and let stand for 3-5 hours to obtain the...

Abstract

The invention relates to a preparation method of an antifogging agent, particularly a preparation method of a glass antifogging agent. Sodium phosphate and sodium tripolyphosphate are used as dispersants, laurinol polyethenoxy ether and fatty acid amine are used as emulsifiers, and polyethyleneglycol and isopropanediol are matched, so that the glass antifogging agent has favorable hydrophilicity and antifogging function, and can prolong the antifogging time and enhance the antifogging effect; and no substance harmful to the human body is added, so the glass antifogging agent can not hurt the human body.

Description

[0001] technical field [0002] The invention relates to a preparation method of an antifogging agent, in particular to a preparation method of a glass 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 glass anti-fogging agent. [0005] In order to achieve the above object, the tech...
