Abstract

PROCEDIMIENTO PARA PRODUCIR MATERIALES ESPUMOSOS ENDURECIDOS PRESENTANDO GRUPOS URETANO Y/O ISOCIANATUROS DE CONSIDERABLES POROS ABIERTOS A TRAVES DE LA TRANSFORMACION DE POLIISOCIANATOS CON COMPUESTOS POR LO MENOS DOS GRUPOS REACTIVOS OPUESTOS A LOS ISOCIANATOS, CUYO PESO EQUIVALENTE DE GRUPOS REACTIVOS ASCIENDE QUIZAS DE 9 HASTA 800, EN PRESENCIA DE CATALIZADORES, SUSTANCIAS ACTIVAS SUPERFICIALMENTE, ASI COMO AGENTES DE INICIACION DE ESPUMAS FISICAS, MEDIOS DE PROTECCION DE LLAMA Y OTROS MEDIOS AUXILIARES Y ACCESORIOS CONOCIDOS, POR LO QUE LA TRANSFORMACION SE REALIZA EN PRESENCIA DE HIDROCARBUROS FLUIDOS DE ELEVADO PESO MOLECULAR QUE ESTAN LIBRES DE GRUPOS REACTIVOS ISOCIANTOS QUE SE ENCUENTRAN EN CANTIDADES DE 0,01 A 3,0% EN PESO RESPECTO DE LA PREPARACION DE LA REACCION. PARTICULARMENTE LOS HIDROCARBUROS PREFERIDOS SON POLIBUTADIENO Y POLIOCTENILENO EN UN PESO MOLECULAR MEDIO DE 800 A 10000 G/MOL. LA MATERIA ESPUMOSA ENDURECIDA PRESENTA DEBIDO A SU POROSIDAD, UNA ELEVADA ESTABILIDAD DEFORMA.
