Embodiment Construction

[0023] A kind of antifogging agent for automobile glass, its raw material is: trifluoropropyl methyl polysiloxane, camellia oil, polypropylene, propylene glycol, sorbic acid alcohol, volatile perfluorinated oil, glycerin and deionized water; The weight percentage is:

[0024] Trifluoropropylmethylpolysiloxane 2~5%;

[0025] Camellia oil 3~5%

[0026] Polypropylene 2~3%

[0027] Propylene glycol 1~3%

[0028] Sorbitol 5~6%

[0029] Volatile perfluorinated oil 2~5%

[0030] Glycerin 2~4%

[0031] The balance is deionized water.

[0032] The trifluoropropylmethylpolysiloxane contains 50% trifluoropropyl substituents and has a relative molecular weight of 200,000.

[0033] The volatile perfluorinated oil is a mixture obtained by diluting the oxidized oil as the base oil with a perfluorinated solvent.

[0034] The weight percentages of the various substances are preferably: 3 trifluoropropylmethylpolysiloxane, 4 camellia oil, 3 polypropylene, 4 propylene glycol, 5 sorbic ac...

Abstract

The invention relates to a glass antifogging agent, in particular relates to an automotive glass antifogging agent, and belongs to the field of antifogging agents. Tea oil, polypropylene and propylene glycol are used as dispersants, and volatile perfluor oil is added, so that the automotive glass antifogging agent has excellent hydrophilicity and antifogging functions, the antifogging time can be prolonged, and the antifogging effect can be improved; and the automotive glass antifogging agent has no harm to a human body as the substance harmful to the human body is not added.

Description

technical field [0001] The invention relates to a preparation method of a glass antifogging agent, in particular to a preparation method of an automobile glass antifogging agent, which belongs to the field of antifogging agents. Background technique [0002] With the continuous development of the automobile industry, the traffic flow on the road is also increasing. It not only brings great pressure to traffic, but also brings certain harm to people's life safety. Especially in winter, the incidence of traffic accidents will increase significantly. On the one hand, the reason is that the road is snowy in winter, and on the other hand, the glass inside the car is covered by water, which affects the driver's line of sight and hinders driving safety. The anti-fogging agents for automobile glass commonly used at present are generally composed of surfactants, etc., and the anti-fogging time is short and the effect is not good. Contents of the invention [0003] In view of the...
