Abstract

METODO DE PREPARACION DE ARTICULOS MOLDEADOS ELASTICOS. CONSISTE EN INTRODUCIR EN UN MOLDE CERRADO, A UNA TEMPERATURA NO INFERIOR A 105JC, UNA MEZCLA QUE SE ENCUENTRA A UNA TEMPERATURA COMPRENDIDA ENTRE 10JC Y 70JC, CONSTITUIDA POR UNA CANTIDAD DE DI- O POLIISOCIANATOS, LIQUIDOS A TEMPERATURA AMBIENTE, A BASE DE DIISOCIANATODIFENILMETANO, TAL QUE EN LA MEZCLA REPRESENTA UN INDICE ISOCIANATO DE 70-130, POR DISOLUCIONES DE DIAMINAS, SUSTITUIDAS POR ALQUILO, QUE CONTIENEN COMO MINIMO DOS GRUPOS REACTIVOS RESPECTO A LOS GRUPOS ISOCIANATO, Y POR AGENTES AUXILIARES Y ADITIVOS; Y DESMOLDEAR EL CUERPO MOLDEADO DESPUES DE 5 A 60 SEGUNDOS. ESTOS ARTICULOS TIENEN APLICACIONES EN LA INDUSTRIA DEL CALZADO, COMO SUELAS Y EN LA DEL AUTOMOVIL, COMO PIEZAS DE CARROCERIA.
