Abstract

L'invention concerne l'utilisation d'une composition de polyisocyanates comme colle dans la fabrication de contre-collages structurels à base de lignocellulose, caractérisée par le fait que ladite composition de polyisocyanates comporte une composition de prépolymères contenant un isocyanate qui présente une teneur en NCO de 5 à 25 % en poids, et peut être obtenue par la mise en réaction d'une composition de polymères réagissant avec l'isocyanate, qui présente une fonctionnalité nominale moyenne de 2 à 4 et un poids équivalent moyen de 500 à 3000, avec un excédent stoechiométrique d'une composition de diphénylméthane diisocyanate.
