Definitions

• This invention regards an agent for surface finishing of objects and structures by a coating layer with a photocatalytic and self-cleaning effect, above all with the catalytic effects of air pollutants' photodegradation as well as the process of this agent's manufacturing.
• bulding materials there are known eg concrete mixtures containing (as an additive) the photocatalytic active titanium dioxide.
• organo-metallic precursors containing particles of photocatalytic active compounds above all of the titanium dioxide; regarding this, there is known usage of precursors which originated by homogenous hydrolysis of the soluble salts (chlorides) of titanium by urea or thioacetamide in aqueous medium.
• the precursors gained can only be used as the active component of respective paint, not as a paint itself.
• This agent for surface finishing of objects and structures by a coating layer with a photocatalytic and self-cleaning effect as per invention is to a large extent instrumental in removing the aforementioned deficiencies of the status quo in this field.
• This invention stipulates in the fact that it consists of a precursor which iis based on a dispersion of at least one compound from the group of metals' oxids and salts in nanocristalline form, being visible even in the visible band of the solar radiation spectrum; the precursor said is a hydrolysis product of respective metal's soluble salt in the medium of silicates, silicic esters, siloxanes or silicon alcoxides.
• this can be above all the titanium oxide, ferric oxide or zirconium dioxide.
• This metal oxide can be further supported by transient metals Oxides, particularly of Fe, Co, Ni, Mn, Cr, V, Ta, Nb and W, and/or lanthanoide oxides, particularly of La, Ce, Nd, Y, Sm, Eu and Dy.
• transient metals Oxides particularly of Fe, Co, Ni, Mn, Cr, V, Ta, Nb and W
• lanthanoide oxides particularly of La, Ce, Nd, Y, Sm, Eu and Dy.
• the agent for surface finishing of objects and structures as per invention is at the same time a precursor and a paint with final qualities gained after spontaneous curing.
• this can be advantageously the titanium(III) chloride, titanium dichloride or titanium oxide chloride.
• a new composite material can be created which is applicable onto any surface type, with final qualities after spontaneous curing. It is strong, perfectly washable, with a self-cleaning or photocatalytic effect due to presence of metal ocide nanoparticles (above all the titanium oxide ones), and-due to chosen combination of various anorganic polymeres-is also suitable for anti-graffiti systems, being also usable as a precursor in the production of more sofisticated paints with other binding systems.
• This agent can be applicated by brushing, spraying or rolling when (after a sufficient dilution) also thin transparent layers can be obtained.
• the surfaces coated in this way have the advantage thet they gain (as against existing transparent paint films), after being illuminated, a highly wettable surface, and due to the photocatalytic effect the organic inpurities or air pollutants adhering to this surface shall be decomposed.
