Definitions

  • Sol / gel processes per se are readily familiar to the person skilled in the art (see, for example, Römpp-Lexikon Chemie, 9th edition, volume 5, page 4140, keyword “sol-gel process” and literature cited therein; CJ Brinker, GW Scheerer, "Sol-Gel-Science: The physics and chemistry of sol-gel processing", Academic Press, San Diego, 1998).
  • the term "sol-gel process” or “sol-gel process” means a process in which glasses or ceramic compositions are finally obtained from initially soluble compounds via the intermediate stage of a gel.
  • Sol / gel precursors suitable according to the invention are in particular selected from the group of di-, tri- and / or tetrafunctional silicic acid, boric acid and aluminum esters, in particular alkoxysilanes (alkyl orthosilicates), and their precursors.
  • sol / gel precursors suitable according to the invention are described, for example, in German patent application 100 21 165.9 of Henkel KGaA dated April 29, 2000 with the designation "system for the release of active substances", the disclosure of which is hereby fully incorporated by reference.
  • organosilanes such as.
  • Surface carrier materials suitable according to the invention, to which the coating composition produced according to the invention can be applied are, for example, glasses and ceramics of all kinds; inorganic oxides such as aluminum oxide, silicon dioxide, magnesium oxide, boron oxide, titanium oxide, etc .; silica gels; Cellulose products of all kinds; Plastic products of all kinds; Fabrics, fabrics, fleeces, knitted fabrics and felts of all kinds; Metals and metal alloys of all kinds; and other, preferably inert carriers and carrier materials as well as macro- and mesoporous carriers. Spherical carrier particles of the aforementioned materials are also suitable as carriers.
  • the present invention thus relates to a process for producing a mass containing active substance and / or active substance, in particular for producing films, layers and / or coatings, which comprises the following process steps:
