Photocatalytic compositions, and uses thereof for obtaining water paints
The field of the invention relates to photocatalytic compositions, e.g. cement-based photocatalytic compositions, and the uses thereof for obtaining water paints. There is provided a photocatalytic composition, which comprises: (a) at least one inorganic binder; (b) at least one photocatalyst; (c) at least one cellulose with very low viscosity; (d) at least one fluidizing agent; (e) at least one first calcareous filler in the form of particles of which at least 95% by weight has a dimension not greater than 40 µm; (f) at least one second calcareous filler in the form of particles of which at least 95% by weight has a dimension not greater than 20 µm; (g) at least one thermal insulator material comprising hollow ceramic spheres with sub- mm diameters, and (h) glass bubble borosilicate microspheres. Advantages include that the hollow ceramic spheres with sub-mm diameters improve the yield (the dried paint area painted per kg of liquid paint) on the surface for the dried paint product, improve the thermal insulation of the dried paint product, and improve the reflectance of the dried paint product; the glass bubble borosilicate microspheres improve the yield (the dried paint area painted per kg of liquid paint) on the surface for the dried paint product, improve the reflectance of the dried paint product and easiness of work of the liquid paint including the composition.
