Abstract

L'INVENTION CONCERNE LA LIAISON DU LIEGE PAR MISE EN CONTACT AVEC UNE COMPOSITION DE POLYISOCYANATE. CETTE COMPOSITION COMPREND UN PREPOLYMERE A POIDS OBTENU PAR REACTION D'UNE COMPSITION POLYMERIQUE, REACTIVE AVEC LES ISOCYANATES, AYANT UNE FOCTIONNALITE NOMINALE MOYENNE DE 1,8 A 6 ET UN POIDS EQUIVALENT MOYEN DE 500 A 7000 AVEC UN EXCES STOECHIOMETRIQUE D'UNE COMPOSITION DE DIPHENYLMETHANE- DIISOCYANATE. APPLICATION : LIAISON PERFECTIONNEE DU LIEGE DANS LA PRODUCTION DE FEUILLES OU DE CORPS MOULESTHE INVENTION CONCERNS THE BINDING OF CORK BY CONTACT WITH A POLYISOCYANATE COMPOSITION. THIS COMPOSITION INCLUDES A WEIGHT PREPOLYMER OBTAINED BY REACTION OF A POLYMERIC COMPSITION, REACTIVE WITH ISOCYANATES, HAVING AN AVERAGE NOMINAL FOCTION OF 1.8 TO 6 AND AN AVERAGE EQUIVALENT WEIGHT OF 500 TO 7000 WITH A STOECHIOMETRIC EXCESS DIPHENYLMETHANE- DIISOCYANATE. APPLICATION: IMPROVED CORK LINK IN THE PRODUCTION OF SHEETS OR MOLDED BODIES
