Abstract

The invention discloses a preparation technology for a self-cleaning antifog glass. According to the preparation technology, twice planting is adopted for respectively planting zinc hydroxystannate and modified nanometer titania on a glass substrate, wherein the modified nanometer titania is aluminum potassium sulfate modified nanometer titania. The self-cleaning antifog glass prepared according to the preparation technology has degradation rate of methyl orange above 85.0%, visible light transmittance above 85%, water drop contact angle theta at 0 degree and an excellent cleaning antifog effect.

Description

technical field [0001] The invention relates to the field of preparation of functional glass, in particular to a preparation process of self-cleaning anti-fog glass. Background technique [0002] Self-cleaning glass refers to the glass whose surface has unique physical and chemical characteristics after being treated by special physical or chemical methods, so that the cleaning effect can be achieved without traditional scrubbing methods. It has been widely used in people's living environment. Glass and glass products, such as architectural glass, curtain wall glass, decorative glass, car windshield, side window glass, etc. Self-cleaning glass can be divided into super-hydrophilic self-cleaning glass and super-hydrophobic self-cleaning glass according to the contact angle between water and glass. The current industrialized products are mainly super-hydrophilic self-cleaning glass. The components of superhydrophilic self-cleaning glass surface films are usually dominated by ...
