A method for extending resin-based wood glues, particularly condensation polymer resin-based glues, comprises the steps of (i) providing an aqueous extender composition comprising 20% to 50% by weight of alkali metal silicate and 1 % to 25% by weight of polyhydric alcohol, preferably a sugar such as sucrose, (ii) providing a solution comprising a resin and (iii) blending the aqueous extender and the solution together to form a glue. The extended glues are suitable for preparing water resistant processed wooden panels such as plywood or chipboard with reduced need for resin. The extended glues do not set excessively rapidly, allowing time for the processing of the wood composites.

L'invention concerne un procédé d'extension de colles à bois à base de résine, notamment de colles à base de résine de polymère obtenu par condensation, ledit procédé comprenant les étapes consistant à (i) utiliser une composition d'extendeur aqueux comprenant 20 % à 50 % en poids d'un silicate de métal alcalin et 1 % à 25 % en poids d'un alcool polyhydrique, de préférence un sucre tel que le sucrose, (ii) utiliser une solution comprenant une résine et (iii) mélanger l'extendeur aqueux et la solution pour former une colle. Les colles étendues conviennent à la préparation de panneaux en poids traités pour être résistants à l'eau, tels que par exemple le contreplaqué ou l'aggloméré, ayant un besoin réduit de résine. Les colles étendues ne durcissent pas de manière excessivement rapide, laissant ainsi du temps pour le traitement des composites en bois.
