About
The invention refers to a nanocomposite coating material with photodegradation and antimicrobial properties, which provides protection (consolidation) for natural stone elements in the composition of vernacular constructions (materials with high calcium content), represented by an alcoholic dispersion, made in a mixture ethanol: isobutyl alcohol, containing a composite material consisting of two phases: a phase based on a double-layered hydroxide mixture (hydrotalcite)/metal oxide nanoparticles (Ti, Zn) of commercial origin and a phase consisting of a mixture of hydroxide calcium and hydroxyapatite in which calcium has or has not been partially dislocated with zinc. The formulation, due to the inorganic composition, presents an improved stability in relation to other formulations based on organic polymers and organic antimicrobial substances.
