Preparation of nano composites by organic modification of nano filler useful as a paint, adhesive, casting composition, in aircraft construction, electronics, automobile finishing, and as a parquet flooring lacquer

A process for preparation of nano composites in which an agglomerated nano filler is organically modified in an organic solvent with silazane, chlorosilane, titanate and/or zincate and the modified nano filler is worked into an organic binder is new. An Independent claim is included for a nano compo...

Beschreibung
Zusammenfassung:	A process for preparation of nano composites in which an agglomerated nano filler is organically modified in an organic solvent with silazane, chlorosilane, titanate and/or zincate and the modified nano filler is worked into an organic binder is new. An Independent claim is included for a nano composite obtained as above where at least 60%, preferably at least 80% of the modified agglomerated filler has a particles size of less than 300 nm. Es wird ein Verfahren zur Herstellung von Nanokompositen aus agglomeriert vorliegenden Nanopulvern und organischen Bindemitteln vorgestellt. Durch Oberflächenmodifikation der Nanofüllstoffe in einem organischen Lösemittel gelingt es, die Agglomerate dauerhaft soweit zu zerteilen, dass transparente Nanokomposite erhalten werden können. Das modifizierte Nanopulver wird bevorzugt als trockenes Zwischenprodukt isoliert. Die Herstellung der vorgestellten Nanokomposite ist einfacher als die Herstellung von Nanokompositen nach der Sol-Gel-Technik und ist zusätzlich flexibler und breiter einsetzbar. Eine wichtige Anwendung für die Nanokomposite sind kratzfeste Lacke.
