Abstract

PROCEDIMIENTO PARA LA OBTENCION DE ESPUMAS CONFORMADAS. SE SOMETE UN COMPUESTO RESINICO REACTIVO A UNA REACCION DE CONDENSACION, EN PRESENCIA DE UN CATALIZADOR, UN AGENTE ESPUMANTE Y ADITIVOS. LA REACCION TIENE LUGAR EN EL INTERIOR DE UN MOLDE QUE PERMITE LA LIBERACION DEL AGUA FORMADA DURANTE LA MISMA; QUEDANDO DICHO AGUA EN COMUNICACION CON LA ESPUMA. CONTROLANDO LA TEMPERATURA DE LA MASA GASEOSA CONTENIDA EN EL MOLDE Y LA DE ESPUMA SE CONSIGUE EL CURADO Y EL CONFORMADO DE ESTA ULTIMA. OPCIONALMENTE PUEDE REALIZARSE UN PRIMER CURADO CON ENERGIA DE ALTA FRECUENCIA. EN OCASIONES PUEDEN RECUBRIRSE LAS SUPERFICIES INTERNAS DEL MOLDE CON UN TEJIDO DE FIBRA DE VIDRIO. COMO COMPUESTO RESINICO SE EMPLEA, PREFERENTEMENTE, UNA RESINA DERIVADA DEL ALCOHOL FURFURILICO, UNA RESINA DE UREA-FORMALDEHIDO O RESINAS FENOLICAS MODIFICADAS CON ALCOHOL FURFURILICO. LAS ESPUMAS CONFORMADAS OBTENIDAS SON DE EMPLEO EN EL AISLAMIENTO DE EDIFICIOS.
