Abstract

The invention discloses a forming method for a glass antifogging coating. The forming method comprises the steps that 3-isocyan acyl propyl dimethyl chlorosilane and anhydrous methylbenzene are mixed to form a first solution; a glass substrate subjected to surface activating treatment is immersed in the first solution for reaction for a first preset time period and then is taken out, so that the immersed glass substrate and a second solution are obtained; a fluorine-contained surfactant is dried and dissolved in the second solution to obtain a third solution; the immersed glass substrate is immersed in the third solution for reaction for a second preset time period and then is taken out to obtain glass with the antifogging coating. The glass antifogging coating formed through the forming method has the characteristics of hydrophilicity and oleophobicity; the receding angle of the oil phase on the glass surface is larger than the advancing angle of water on the glass surface, so it can be guaranteed that the oil phase rolls off the glass substrate surface together with the water phase, and good self-cleaning performance is obtained.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a method for forming a glass anti-fog coating. Background technique [0002] At present, the research on anti-fog coating has a very broad application prospect in industry, agriculture, and daily life. In recent years, the research on glass anti-fog coating has also been more in-depth research. The widely researched anti-fog coatings, whether hydrophilic coatings or hydrophobic coatings, only make the silicate glass have anti-fog effect, but the anti-water and oil pollution effect is not great, making the anti-fog effect durable Not strong. However, with the development of the automobile industry, the application of glass is becoming more and more obvious, and the pollution of oil pollution to automobile glass needs to be solved. Contents of the invention [0003] This application provides a method for forming a glass anti-fog coating, which solves the problem that ...
