Abstract

PROCEDIMIENTO PARA LA OBTENCION DE PIEZAS MOLDEADAS DE POLIURETANO MEDIANTE MOLDEO POR INYECCION. UNA MEZCLA LIQUIDA DE REACTANTES DE POLIURETANO SE INTRODUCE EN UN MOLDE EN EL QUE ES MOLDEADA A TEMPERATURA ELEVADA Y DEL QUE SE EXTRAE POSTERIORMENTE. ESTE MOLDE SE RECUBRE ANTES DE INTRODUCIR LA MEZCLA, CON UNA COMPOSICION QUE CONTIENE DE UN 0,005 A UN 10 POR 100 EN PESO DE UN CATALIZADOR DE POLIURETANO QUE ACTUA UNIENDO ESTE RECUBRIMIENTO A LA PIEZA MOLDEADA, DE FORMA QUE CUANDO ESTA SE EXTRAE DEL MOLDE YA TIENE EL RECUBRIMIENTO ADHERIDO A ELLA.
