Abstract

LA INVENCION SE REFIERE A UNA MEZCLA DE POLIISOCIANATO QUE TIENE UN CONTENIDO DE NCO DE ENTRE 10 Y 47% Y UNA VISCOSIDAD INFERIOR A 10,000 MPA.S Y QUE CONTIENE GRUPOS DE ISOCINATURO Y DE ALOFANATO EN UNA RELACION MOLAR DE LOS MONOISOCIANURATOS CON RESPECTO A LOS MONOALOFANATOS DE ENTRE 10:1 Y 1:5, EN DONDE LOS GRUPOS DE ALOFANATOS SE FORMAN A PARTIR DE GRUPOS DE URETANO LOS CUALES SE BASAN EN EL PRODUCTO DE REACCION DE UN DISOCIANATO ORGANICO QUE TIENE GRUPOS (CICLO) ALIFATICOS UNIDOS AL ISOCIANATO Y UN MONOALCOHOL QUE CONTIENE ENTRE 1 Y 5 ATOMOS DE CARBONO. LA INVENCION SE REFIERE TAMBIEN A UN PROCESO PARA LA PRODUCCION DE UNA MEZCLA DE POLIISOCIANATO QUE TIENE UN CONTENIDO DE NCO DE ENTRE 10 Y 47%, UNA VISCOSIDAD INFERIOR A 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 2:1 Y 1:5, MEDIANTE: A) LA TRIMERIZACION CATALITICA DE UNA PARTE DE LOS GRUPOS DE ISOCIANATO DE UN DISOCIANATO ORGANICO QUE TIENE GRUPOS DE ISOCIANATO (CICLO) ALIFATICAMENTE UNIDOS B) LA ADICION DE ENTRE 0.001 Y 0.5 MOLES, POR MOL DE DISOCIANATO ORGANICO , DE UN MONOALCOHOL QUE CONTIENE ENTRE 1 Y 5 ATOMOS DE CARBONO AL DIISOCIANATO ORGANICO ANTES O DURANTE LA REACCION DE TRIMERIZACION DEL PASO A) Y C) LA TERMINACION DE LA REACCION DE TRIMERIZACION EN EL GRADO DESEADO DE TRIMERIZACION MEDIANTE LA ADICION DE UN DEGRADANTE DEL CATALIZADOR Y/O MEDIANTE LA DESACTIVACION TERMICA DEL CATALIZADOR. FINALMENTE, LA PRESENTE INVENCION SE REFIERE AL USO DE ESTAS MEZCLAS DE POLIISOCIANATO, OPCIONALMENTE EN FORMA DE BLOQUE, COMO COMPONENTES DE ISOCIANATO EN COMPUESTOS DE REVESTIMIENTO DE DOS COMPONENTES.
