Abstract

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Holzwerkstoffen aus lignocellulosehaltigen Zerkleinerungsprodukten, wobei eine Verminderung der Emission von flüchtigen organischen Verbindungen und Aldehyden einschließlich Formaldehyd aus Holz, den Zerkleinerungsprodukten und dem hergestellten Holzwerkstoff erreicht wird. Genauer betrifft die vorliegende Erfindung Verfahren zur Verminderung der Emission von flüchtigen organischen Verbindungen und Aldehyden einschließlich Formaldehyd wobei Holz oder die lignocellulosehaltige Zerkleinerungsprodukte mit Thiosulfaten, bevorzugt mit einer bestimmten Kombination von Verbindungen aus Thiosulfaten und Harnstoffen, behandelt werden, um die Emission dieser flüchtigen organischen Verbindungen einschließlich Aldehyden aus dem hergestellten Holzwerkstoff zu verhindern. Weiterhin betrifft die vorliegende Erfindung mit diesem Verfahren herstellbare Holzwerkstoffe. Insbesondere stellt die vorliegende Erfindung Behandlungsmittel zur Behandlung von Holz oder lignocellulosehaltigen Zerkleinerungsprodukten und daraus hergestellten Holzwerkstoffen bereit, die geeignet sind, die Emission von Aldehyden einschließlich Formaldehyd und flüchtigen organischen Verbindungen zu reduzieren und deren entsprechende Verwendung.
