Embodiment 1

[0024] Into a 2000ml three-necked flask with mechanical stirring, thermometer and reflux condenser inserted in sequence, add surfactant CH in sequence 3 O(CH 3 CH 2 CH 2 o) n (CH 2 CH 2 o) m CH 3 O, (n=6, m=5), 50g, ionic liquid 20g, antifoaming agent cyclotetrasiloxane 2g, diluent alcohol 200g, diluent deionized water 1650g. Then stir mechanically for 30 minutes. Pour the mixed liquid in the four-necked flask into a 2000ml ground-mouth jar to obtain the demister of the present invention. Wherein, the chemical formula of ionic liquid is:

[0025]

[0026] The defogger can be filled into an atomized sprayer before use, or evenly spread on a pure cotton rag. Just apply it evenly on the glass surface before testing.

[0027] The pH value of the product is tested by precision pH test paper, the rubber swelling is tested by the national standard GB / T14832, the corrosion is tested by the national standard GB / T11143, and the defogging effect is evaluated by four levels:...

Abstract

The invention relates to a normal temperature type automobile glass fog remover, which is suitable for defogging and defrosting of automobile front and back windshields and rearview mirrors. The normal temperature type automobile glass fog remover is characterized in that it is prepared by mixing and stirring the following raw materials by weight: 0.02-0.05wt% of a surfactant; 0.01-0.02wt% of a film forming agent; 0.001-0.002wt% of a defoaming agent; and the balance a diluents. Specifically, the surfactant is a CH3O (CH3CH2CH2O)n (CH2CH2O)mCH3O type nonionic surfactant, wherein n ranges from 2 to 6, and m ranges from 5 to 10. Compared with the prior art, the fog remover provided by the invention has active and lasting defogging effects, is environmental friendly, involves no volatile organic substance, and is harmless to drivers and passengers in driving cabs.

Description

technical field [0001] The invention relates to a normal-temperature type automobile glass defogger, which is suitable for defogging and defrosting the front and rear windshields and side mirrors of automobiles. The use environment of the invention is that the temperature is higher than -10°C. Background technique [0002] On cloudy and rainy days, after closing all the windows of the car, there will be a lot of water mist due to the low temperature outside the car and the high temperature inside the car. The physical principle is that there is a large amount of water vapor in the car, which liquefies into small water droplets when it meets the cold car glass. When the weather turns cold, there is always a layer of small water droplets on the outside of the car outside, which is dew. This is because the water vapor in the air liquefies when it encounters a cold car at night. When it gets colder in winter, there will be a thin layer of frost on the outside of the car. Sinc...
