Abstract

EL PROCEDIMIENTO PARA PRODUCIR ESPUMAS DE POLIURETANO BLANDAS Y TERMOENDURECIBLES SE REALIZA MEDIANTE LA TRANSFORMACION DE A) POLIISOCIANATOS CON B) COMPUESTOS QUE TIENEN UN PESO MOLECULAR ENTRE 400 Y 10.000 Y DOS HIDROGENOS ACTIVOS EN LOS GRUPOS ISOCIANATOS Y CON C) PROLONGADORES DE CADENA O RETICULANTES, EN PRESENCIA DE CATALIZADORES CON DIFUSORES COMO AGUA, OTROS DIFUSORES, CATALIZADORES Y DE SUSTANCIAS AUXILIARES Y ADITIVOS EN FORMA CERRADA. EL PRODUCTO DE TRANSFORMACION ES APROXIMADAMENTE EL 85% EN PESO DE LA COMPOSICION. LOS POLIISOCIANATOS SON DEL TIPO DE LOS DIFENILMETANODIISOCIANATO Y/O DE LOS TOLUILENODIISOCIANATOS Y/O HEXAMETILENO DIISOCIANATO Y/O ISOFOSFORODIISOCIANATO. LOS RETICULANTES TIENEN DOS HIDROGENOS ACTIVOS EN CADA ISOCIANATO Y UN PESO MOLECULAR ENTRE 32 Y 399. EL CATALIZADOR QUE SE UTILIZA ES UNA DIAMIDA DEL ACIDO CARBONICO EN UN 0,05 A 1,0 EN PESO RESPECTO A LA COMPOSICION TOTOAL DEL COMPONENTE B). EL DIFUSOR ES AGUA EN UN 5 A 15% EN PESO RESPECTO AL COMPONENTE B).
