The low-radiation self-cleaning composite functional glass disclosed by the invention has a three-layer film structure, and the film layer is SiO2 transition layer from the glass outward, ion-doped SnO2 layer, and ion-doped SiO2-TiO2 layer. The on-line preparation method is a sol-gel method, combined with an atomization deposition method, using a thermal decomposition gelation process of a sol at a temperature of 450 ° C to 550 ° C for thermal deposition, and a film layer is sequentially formed on an in-line glass plate surface. The invention has reasonable control of coating material concentration, doping ion species, thermal decomposition temperature and film thickness, so that the glass coated with the film has low radiation performance, and is stable monolithic low-emissivity glass, and the use cost is lowered. And can achieve low-radiation tempering and hot bending and other reprocessing. Can be applied to ordinary building houses and car front windshield. By controlling the crystal form of the outer protective film layer TiO2, the film layer has photocatalytic performance, and achieves antibacterial and self-cleaning effects. The dual function of low radiation and self-cleaning of the glass is achieved.
