Forming method for glass antifogging coating

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.
