(FR) PROCEDE DE PRODUCTION DE MATERIAUX MOULES PAR COMPRESSION AVEC DES LIANTS POLYISOCYANATE, AVEC UTILISATION SIMULTANEE DE CATALYSEURS THERMO-ACTIVABLES LATENTS
Abstract
(DE)
Beschrieben wird ein Verfahren zur Herstellung von Preßwerkstoffen, insbesondere von Holz-Spanplatten, durch Heißverpressen von mit Polyisocyanaten als Bindemittel vermischten und/oder imprägnierten lignosecellulosehaltigen Werkstoffen unter Verwendung von latenten durch Wärme aktivierbaren Katalysatoren, bei dem als Katalysatoren Ammoniumsalze aus der Umsetzung von Aminen mit Malonsäure eingesetzt werden.
(EN)
The disclosure relates to a method of producing press-moulding materials, in particular wood chip boards, by hot pressing of materials containing lignocellulose and mixed and/or impregnated with polyisocyanates as binders, using latent, heat activable catalysts in the form of ammonium salts obtained from the reaction of amines with malonic acid.
(FR)
L'invention concerne un procédé de production de matériaux moulés par compression, notamment de panneaux d'agglomérés en bois, par thermocompression de matériaux contenant de la lignocellulose, mélangés à des polyisocyanates et/ou imprégnés desdits polyisocyanates, à l'aide de catalyseurs thermo-activables latents. Selon ce procédé, les catalyseurs utilisés sont des sels d'ammonium issus de la réaction d'amines avec de l'acide malonique.
