Nanokomposite, Verfahren zu ihrer Herstellung und ihre Verwendung

DE 10241510 A UPAB: 20040429 NOVELTY - 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. DETAILED DESCRIPTION - 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. USE - The nano composite is useful as a paint, adhesive, as a casting composition or for shaped plastics parts (claimed), in aircraft construction claimed), in electronics (claimed), in automobile finishing (claimed), in painting transparent plastic (claimed), e.g. polycarbonate automobile window panes (claimed), and as a parquet flooring lacquer (claimed), and for preparation of thermoplastics. ADVANTAGE - The method requires much smaller quantities of expensive organic components than the sol-gel process, and when the nano composite is used in paints the crack and abrasion resistance are increased and transparency is retained, which is especially important in automobile finishing and parquet flooring applications
