Description
Technical Field
The invention belongs to the field of coatings, and particularly relates to a super-hydrophilic anti-fogging coating.
Background
The temperature is low, the indoor air temperature is high, and when water vapor in the air meets cold glass, the water vapor is condensed into small water drops to be attached to the surface of the glass; the glass is fogged mainly because the temperature difference between the inner side and the outer side of the glass is too large; the antifogging coating is a coating which is expressed in a coating form and has the function of preventing fog from condensing; the mist is composed of numerous small droplets. The hot air touches cold objects and is condensed into small water drops on the surface of the cold objects, and light rays hit the surfaces of the small water drops to generate diffuse reflection, so that the light transmittance of the material is reduced, and the material gives people a feeling of fogging. Therefore, the antifogging coating enables the surface of the base material to have super-hydrophilic characteristics, the surface tension of water is increased, water cannot form water drops on the surface of the base material, but the water film is formed by flattening the surface of the base material, so that light rays can normally pass through the base material without influencing the sight, and the antifogging effect is achieved; however, the existing antifogging coating has large pollution and does not accord with the sustainable development direction advocated by the existing society;
