Problems solved by technology

[0003] The research of traditional glass surface superhydrophilic agents mainly focuses on nano-TiO 2 thin film, but TiO 2 Films generally need to be induced by ultraviolet rays to show superhydrophilicity, and the treatment process is more complicated. However, the method of using surfactants to treat the glass surface is simple but lacks durability.

Abstract

The invention relates to a super-hydrophilicity and high-adhesion glass surface treatment agent and a preparation method thereof. The treatment agent is prepared from SiO2 sol and a Si-PEG polymer solution, wherein the mass ratio of the SiO2 sol to the Si-PEG polymer solution is (1:1) to (1:5); the SiO2 sol is prepared by the steps of uniformly mixing absolute ethyl alcohol, ethyl orthosilicate, silane and deionized water, reacting at 20 to 40 DEG C for 5 to 7 hours, and standing at room temperature for 12 to 24 hours after the reaction; the Si-PEG polymer solution is prepared by the steps ofslowly dropwise adding chlorosilane into polyethylene glycol, reacting for 3 to 5 hours, and then adding an organic solvent. The super-hydrophilicity treatment agent has good scrubbing resistance, issimple to use, can be directly applied to the surface of glass to form a transparent super-hydrophilic film, has the advantages of short consumption time, long effect lasting time and low cost, and can be applied to building exterior glass, car windshield, etc.

Description

technical field [0001] The invention relates to the technical field of hydrophilic glass, in particular to a glass surface superhydrophilic and high adhesion treatment agent and a preparation method thereof. Background technique [0002] As two extreme wetting phenomena, superhydrophilic and superhydrophobic have attracted the attention of scholars at home and abroad. In general, a superhydrophobic surface refers to a surface with a solid-liquid contact angle greater than 150°. On the contrary, a superhydrophilic surface refers to a surface on which a liquid can spread completely and the contact angle is close to or equal to 0°. Both superhydrophilic and superhydrophobic can make the surface self-cleaning to some extent, but when the superhydrophobic surface faces water mist, it is difficult for small water droplets to roll off the surface, and the stains will remain after the water droplets evaporate on the surface. This situation makes the super-hydrophilic surface highl...
