Abstract

LA INVENCION SE DIRIGE A UNA MEZCLA DE POLIISOCIANATO QUE TIENE UN CONTENIDO DE NCO DE ENTRE EL 10 Y 47% DE UNA VISCOSIDAD INFERIOR A 10,000 MPA.S Y QUE CONTIENE GRUPOS DE ISOCIANURATO Y DE ALOFANATO EN UNA RELACION MOLAR DE MONOISOCIANURATOS CON RESPECTO A LOS MONOALOFANATOS DE ENTRE 10:1 Y 1:5, EN DONDE LOS GRUPOS DE ALOFANATO ESTAN FORMADOS A PARTIR DE GRUPOS DE URETANO QUE SE BASAN EN EL PRODUCTO DE REACCION DE UN DIISOCIANATO ORGANICO QUE TIENE GRUPOS DE ISOCIANATO DE ENLACE (CICLO)ALIFATICO Y UN MONOALCOHOL AROMATICO QUE CONTIENE ENTRE 6 Y 9 ATOMOS DE CARBONO. LA INVENCION TAMBIEN SE DIRIGE A UN PROCESO PARA LA PRODUCCION DE UNA MEZCLA DE POLIISOCIANATO QUE TIENE UN CONTENIDO NCO DE ENTRE EL 10 Y 47%, QUE TIENE UNA VISCOSIDAD MENOR DE 10,000 MPA.S Y QUE CONTIENE GRUPOS DE ISOCIANURATO Y DE ALOFANATO EN UNA RELACION MOLAR DE LOS MONOISOCIANURATOS CON RESPECTO A LOS MONOALOFANATOS DE ENTRE 10:1 Y 1:5, EL PROCESO COMPRENDE: A) LA TRIMERIZACION CATALITICA DE UNA PARTE DE LOS GRUPOS DE ISOCIANATO DE UN DIISOCIANATO ORGANICO QUE TENGA GRUPOS DE ISOCIANATO UNIDOS (CICLO)ALIFATICAMENTE. B) LA ADICION DE ENTRE 0.01 Y 0.5 MOLES, POR MOL DE DIISOCIANATO ORGANICO, DE UN MONOALCOHOL AROMATICO QUE CONTIENE ENTRE 6 Y 9 ATOMOS DE CARBONO AL DIISOCIANATO ORGANICO ANTES O DURANTE LA REACCION DE TRIMERIZACION DEL PASO A) Y C) LA FINALIZACION DE LA REACCION DE TRIMERIZACION EN EL GRADO DESEADO DE TRIMERIZACION MEDIANTE LA ADICION DE UN TOXICO PARA EL CATALIZADOR Y/O DESACTIVANDO TERMICAMENTE EL CATALIZADOR. FINALMENTE, LA INVENCION SE DIRIGE AL USO DE LAS MEZCLAS DE POLIISOCIANATO, OPCIONALMENTE EN FORMA BLOQUEADA, COMO COMPONENTE DE ISOCIANATO EN LA COMPOSICION DE REVESTIMIENTOS DE DOS COMPONENTES.
