Problems solved by technology

[0003] In order to remove the fog on the automobile glass, people have invented anti-fog agents. The existing anti-fog agents are sprayed on the glass and wiped with paper or towel. The duration is relatively short, and the glass will soon generate fog again; The agent contains a large amount of chemical components, which are corrosive to the glass, and will cause damage to the glass of the car if used for a long time

Embodiment Construction

[0017] The invention provides a glass antifogging agent, the components of the embodiment and the weight ratio of each component are respectively: 10% sodium dodecylbenzenesulfonate, 3.8% alkanolamide, and 99% glycerin 1.3%, concentration of 30% sodium hydroxide aqueous solution 0.1%, concentration of 30% hydrochloric acid aqueous solution 0.1%, essence 0.2%, the amount is water, adding essence can improve the fragrance of the anti-fogging agent, and emit a relatively fresh Pleasant aroma, can be optionally added as needed.

[0018] The preparation method of the glass anti-fogging agent is as follows: First, mix sodium dodecylbenzenesulfonate and appropriate amount of water according to the amount, stir evenly, add 30% sodium hydroxide solution to adjust the pH value to 5-6; Add alkanolamide and glycerin while stirring, then add 30% hydrochloric acid aqueous solution to adjust the pH value to 7; add a small amount of essence according to personal preference, and stir evenly; t...

Abstract

The invention discloses an antifogging agent for glass. The antifogging agent comprises the following components by content: 8%-12% of sodium dodecyl benzene sulfonate, 3%-5% of alkanolamide, 1%-2% of glycerol with the concentration of 99%, 0.01%-0.2% of a sodium hydroxide water solution with the concentration of 30%, 0.01%-0.2% of hydrochloric acid water solution with the concentration of 30%, and the balance of water. The antifogging agent for glass disclosed by the invention is obvious in demisting effect and long in action time; water is used as a solvent, so that the explosion hazard is not generated, and the antifogging agent is relatively environment-friendly; and the glass is not damaged after the antifogging agent is used for a long period of time.

Description

technical field [0001] The invention relates to a glass antifogging agent, in particular to an antifogging agent for automobile windshields. Background technique [0002] In the winter when the temperature is relatively low, due to the temperature difference between the inside and outside of the car, a large amount of fog will be generated on the windshield of the car, which will seriously reduce the transparency of the glass and affect the driver's sight. Therefore, the driver will constantly wipe the glass during driving, which is prone to traffic accidents. [0003] In order to remove the fog on the automobile glass, people have invented anti-fog agents. The existing anti-fog agents are sprayed on the glass and wiped with paper or towel. The duration is relatively short, and the glass will soon generate fog again; The agent contains a large amount of chemical components, which are corrosive to the glass, and will cause damage to the car glass if used for a long time.
