The invention discloses a preparation method of anti-reflection self-cleaning coated glass, which comprises the steps of preparing a SiO2-TiO2 composite sol firstly, then carrying out film coating by using a pulling method, and forming a coarse nano thin film layer on the surface of a glass substrate through the SiO2-TiO2 composite sol; and finally, carrying out low-temperature post-treatment on the obtained product so as to obtain coated glass. By using the preparation method disclosed by the invention, the visible light transmittance of the prepared coated glass can be improved, the light transmittance is increased by 2-3%, and the prepared coated glass can achieve a photocatalytic self-cleaning effect. The preparation method disclosed by the invention is simple, a glass substrate is not required to be subjected to complex pretreatment, and coated glass is not required to be subjected to high-temperature baking. The coated glass prepared by using the method disclosed by the invention has excellent ultraviolet aging resistance; and because a coated layer is a nano film, and the surface of the nano film has a proper roughness, the nano film can achieve a physical hydrophilic effect, so that the coated layer on the surface of the glass substrate also can have a super-hydrophilic self-cleaning performance under the condition of no light.
