Abstract

The invention discloses anti-fog glass for an automobile and a preparation method. The glass is prepared from the following components: silicon dioxide, sodium silicate, aluminium oxide, calcium oxide, magnesium oxide, sodium oxide, titanium dioxide, butyl titanate, glycerol, 2M hydrochloric acid and a proper amount of a solvent. The preparation method comprises the following steps: firstly, preparing a glass substrate, and then coating the surface of the glass substrate with a nanometer titania coating film. The glass has a relatively good anti-fog effect, relatively good water-tolerant and wiping-resistant properties; when being applied to automotive mount, the glass is capable of effectively avoiding the fogging phenomenon of the automotive glass caused by large temperature difference between inside and outside of the automobile, and the use safety is greatly improved.

Description

technical field [0001] The invention relates to the technical field of glass materials, in particular to an anti-fog glass for automobiles and a preparation method thereof. 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 or summer rainy days, there is a large temperature difference between the inside and outside of the car. When the temperature of the inner surface of the glass reaches the dew point temperature, water vapor will condense on the glass surface, forming densely packed small water droplets. Due to the existence of these tiny water droplets, light will be refracted and reflected when passing through the glass, which will significantly reduce the light transmittance of the glass, seriously affect the clarity of the driver's sight, and easily lead to traff...
