Anti-fog composition for anti-fog use

The present invention relates to a composition, particularly an anti-fog composition, and the present invention further comprises an antifogging sheet made of the anti-fog composition, and an anti-fog coating made of the anti-fog composition.

The moisture in the air will naturally condense on objects whose surface temperature is significantly lower than that of air to form small water droplets on the surface of the object. Such natural phenomena often cause many inconveniences to life, such as: the morning window glass is attached with water mist, and After the sun shines and evaporates and dries, annoying water stains are formed on the glass. Not only that, for people living in low temperature areas, the problem of condensation of water mist is more likely to cause accidents, such as: often condensed in the window glass. Foggy water is a major concern for driving safety. Therefore, how to effectively prevent fogging from condensing on objects has become a very important issue.

In general, a defogging agent or an electric heater is often used for defogging, wherein a user applies an antifogging agent to the surface of the article to be defogged to form an antifogging film, and the antifogging agent comprises an interface activity. The agent and the organic solvent, when the anti-fog film is formed, can reduce the surface tension of the water vapor on the surface of the object, so that the moisture does not easily condense on the surface of the article to form droplets, thereby achieving the anti-fog effect. In addition, the user can also use the electric heater to contact the surface of the article to increase the temperature of the surface of the article and reduce the occurrence of condensation of water in the air.

However, the durability of the anti-fogging agent is not high, and the anti-fogging agent is often applied to the surface of the article for a period of time, that is, due to friction between the article and the foreign object, cutting, or being washed by heavy rain. The anti-fog film is detached, thereby losing the anti-fog effect on the article. Therefore, when the anti-fogging agent is used to prevent the mist from forming on the surface of the article, it is necessary to repeatedly spray the spray to maintain the effect. However, since the spray contains high volatilization Sexual organic solvents, repeated spraying can even have a negative impact on human health. In addition, in order to increase the temperature of the article by the electric heater, it is necessary to continuously supply electric power to maintain the article at a predetermined temperature to prevent the water vapor from being condensed, so that a large amount of energy cost is invested in anti-fog, which is obvious in the current environmental protection.
