Die Erfindung betrifft ein Verfahren zur Herstellung von Holzwerkstoffen durch Heissverpressen von mit Polyisocyanaten als Bindemittel beleimten lignocellulosehaltigen Materialien unter Verwendung von in Polyisocyanaten lagerstabilen Aminkatalysatoren. The invention relates to a method for producing wood materials by hot-pressing lignocellulose-containing materials that are coated with polyisocyanates as a binder, using amine catalysts that are storage-stable in polyisocyanates. La présente invention concerne un procédé de production de matériaux à base de bois, par compression à chaud de matériaux contenant de la lignocellulose et revêtus de polyisocyanates servant de liant, avec utilisation de catalyseurs à base d'amine qui sont stables au stockage dans des polyisocyanates.
