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.

Abstract

L'invention concerne un agent de finition de surface d'objets et de structures au moyen d'une couche de revêtement à effet photocatalytique et auto-nettoyant, essentiellement à effet catalytique de photodégradation de polluants de l'air. Ledit agent est produit au moyen d'un précurseur à base de dispersion d'au moins un composé sélectionné dans le groupe formé par des oxydes métalliques et des sels sous forme nanocristalline, qui est photoactif même dans la bande visible du spectre de rayonnement solaire. Le précurseur est un produit d'hydrolyse de sels métalliques respectifs solubles dans un milieu de silicates, d'esters siliciques, de siloxanes ou d'alcoxydes de silicium.
