Abstract

The invention relates to a self-cleaning anti-fog element and a manufacturing method thereof. The anti-fog element comprises a light-transmitting base material, a light-transmitting barrier film and a photocatalysis base film, wherein the light-transmitting barrier film is formed on one side surface of the base material; the photocatalysis base film is formed on the barrier film and is a TiO2 or ZnO or SnO2 film with a porous structure, and the rate of pore volume to total volume of the TiO2 or ZnO or SnO2 film is 5-25%; and a photocatalysis hard film is further formed on the photocatalysis film and is a TiO2 or ZnO or SnO2 film with a porous structure, and the rate of pore volume to total volume of the TiO2 or ZnO or SnO2 film is less than 5%. The photocatalysis base film and the photocatalysis hard film of the self-cleaning anti-fog element provided by the invention have large specific surface, and have strong photocatalysis capability even if the thickness is thin; the photocatalysis hard film is good in hydrophily, abrasive resistance, acid resistance, alkali resistance and weather resistance; and the anti-fog element provided by the invention can be manufactured into an adhesive film by using a soft plastic base material, and is flexible to use.

Description

technical field [0001] The invention relates to a self-cleaning anti-fog element, such as anti-fog glass and anti-fog film, and also relates to a manufacturing method of the anti-fog element. Background technique [0002] In daily life and industrial production activities, when building window glass, car windshield, window glass and reflector, etc., when encountering humid air condensation, it is easy to form many tiny water droplets (fog) on ​​the mirror or glass surface. ) and astigmatism, which reduces the transparency and affects the line of sight, causing inconvenience. [0003] The surface functional film material of self-cleaning glass that has been put into use and researched and developed is mainly TiO 2 and TiO 2 Compounds doped with other metals, metal oxides, or other elements. The self-cleaning function of superhydrophilic self-cleaning glass is manifested in two aspects: one is the ability of photocatalytic decomposition of organic matter. TiO 2 Under the ...
