Patent
CA 2482630
The invention relates to a transparent substrate based on glass or polymers, or a ceramic or vitroceramic substrate, or a building material such as a façade coating, flagstones or pavings made from concrete, construction concrete, tiles, cement materials, terracotta, slate, stone, metal surfaces or glassy fibrous substrates such as mineral insulation wool or glass reinforcement threads. Said substrate is characterised in being provided with a coating on at least a part of the surface thereof, having a mesoporous structure with photocatalytic properties and comprising at least partially crystalline titanium oxide. The invention further relates to the production of said substrate, the application thereof in a glazed unit, a building material or an insulating mineral wool.
L'invention concerne un substrat transparent à base de verre ou de polymère(s) ou substrat céramique ou vitro-céramique ou en matériau architectural du type enduit de façade, dalles ou pavé de béton, béton architectronique, tuile, matériau à composition cimentaire, terre cuite, ardoise, pierre, surface métallique, ou substrat fibreux à base verrière du type laine minérale d'isolation ou fils de verre de renforcement. Ce substrat se distingue en ce qu'il est muni sur une partie au moins de sa surface d'un revêtement dont la structure mésoporeuse présente des propriétés photocatalytiques et comporte de l'oxyde de titane au moins partiellement cristallisé. Procédé de fabrication de ce substrat, son application dans un vitrage, un matériau architectural ou une laine minérale d'isolation.
