currently, existing superhydrophilic coatings are mostly achieved by introducing hydrophilic nanoparticles. Such as a super-hydrophilic film based on titanium dioxide photocatalysis, a surfactant coated super-hydrophilic surface. The titanium dioxide super-hydrophilic coating with a single component does not show hydrophilicity any more after the irradiation of an ultraviolet lamp is removed, but the long-acting property of the titanium dioxide super-hydrophilic coating cannot be ensured indoors, so that the application range of the titanium dioxide super-hydrophilic coating is limited. Surfactants tend to run off and are not resistant to wiping and solvents.

Referring to fig. 1, a schematic diagram of a super-hydrophilic functional coating according to the present invention is shown. The precursor solution of the super-hydrophilic functional coating based on the cage-shaped polysilsesquioxane comprises main body resin, hydrophilic nano silicon dioxide particles and a solvent; the main resin is a main resin with alkoxy prepared by the reaction of epoxy cage polysilsesquioxane and secondary amino siloxane.
Wherein the mass ratio of the nano silicon dioxide particles to the main resin is 2-8: 1, and the mass of the solvent is 50-95% of the total mass. The molar ratio of the epoxy cage polysilsesquioxane to the secondary amino siloxane is 1: 8.
in a preferred implementation, the epoxy cage-shaped polysilsesquioxane is one or two of glycidyl ether oxypropyl cage-shaped polysilsesquioxane and epoxy cyclohexyl ethyl cage-shaped polysilsesquioxane, and the particle size of the epoxy cage-shaped polysilsesquioxane is 1-3 nm. The invention utilizes the nanometer size effect of the cage-shaped polysilsesquioxane and the size effect of the hydrophilic nanometer silicon dioxide to prepare the super-hydrophilic coating which has certain surface roughness and hydroxyl hydrophilic groups on the surface, and the water contact angle is less than 5 degrees. Meanwhile, the existence of the cage-shaped polysilsesquioxane can effectively promote the dispersion effect of the nano silicon dioxide.
In a preferred embodiment, the secondary aminosilicone is one or more of N-N-butyl-3-aminopropyltrimethoxysilane, N-N-butyl-3-aminopropyltriethoxysilane, bis- [3- (trimethoxy silicon) -propyl ] -amine, bis- [3- (triethoxy silicon) -propyl ] -amine, 3-anilinopropyltrimethoxysilane, 3- (phenylamino) propyltriethoxysilane, 3- (N-cyclohexylamine) propyltrimethoxysilane and 3- (N-cyclohexylamine) propylmethyldimethoxysilane.
