PROCEDIMIENTO PARA LA OBTENCION DE UN RECUBRIMIENTO SOL-GEL HIBRIDO EN SUPERFICIES CON ESMALTES CERAMICOS VITRIFICADOS Y RECUBRIMIENTO OBTENIDO

Procedure for obtaining a hybrid sol-gel coating on surfaces with vitrified ceramic glazes and obtained coating. The process for obtaining an organic-inorganic functional hybrid sol-gel coating on a vitrified ceramic glaze substrate comprises a thermally consolidated inorganic matrix layer having such porosity that it allows the incorporation of organic molecules in a concentration of up to 75%. % by weight of the equivalent inorganic compound constituting the sol-gel coating to give a hybrid coating. The coating structure comprises at least 3 layers of a thickness of up to 800 nm each layer. The outer layer corresponds to a coating containing dispersed inorganic nanoparticles and inner layers with a porous inorganic matrix containing dispersed nanoparticles. The porous structure is filled with functional hybrid sol-gel by impregnation. The structure thus obtained presents adequate response of the surface to the requirements of brightness, ease of cleaning, resistance to chemical attack and wear of sanitary pieces allowing the incorporation of new functionalities to a sanitary piece.
