Abstract

PROCEDIMIENTO PARA PREPARAR ESPUMAS DE POLIURETANO, ESPECIALMENTE RIGIDAS, A BASE DE UNA COMPOSICION QUE CONTIENE HIDROGENOACTIVO Y UNA DIALCANOL-AMINA TERCIARIA. CONSISTE EN HACER REACCIONAR UN POLIISOCIANATO Y UNA COMPOSICION QUE CONTIENE HIDROGENO ACTIVO Y QUE COMPRENDE AL MENOS UN POLIAHL, UNA CANTIDAD MENOR DE AGUA Y UNA DIALCOLAMINA TERCIARIA. LA REACCION SE CONDUCE EN PRESENCIA DE UN AGENTE DE SOPLADO AUXILIAR. SE UTILIZAN PARA AISLAMIENTO TERMICO EN FRIGORIFICOS, CONGELADORES, TEJADOS, PAREDES Y ANALOGOS.
