Abstract

UN NUEVO PROCESO DE FABRICACION DE CUERPOS DE MOLDE EN ELASTOMERO SOBRE UNA BASE DE PRODUCTOS DE POLIADICION DE POLI ISOCIANATOS PROVINIENDO DE POLI - ISOCIANATOS ORGANICOS, CONTENIENDO GRUPOS CARBAMIDOS Y COMBINACIONES CON GRUPOS, CAPACES DE REACCIONAR FRENTE A LOS GRUPOS ISOCIANATOS, DEL DOMINIO DE PESO MOLECULAR ENTRE 500 Y 1200, AGUA, EVENTUALMENTE COMBINACIONES ORGANICAS CON ATOMOS DE HIDROGENO CAPACES DE REACCION FRENTE A LOS GRUPOS ISOCIANATOS, DEL DOMINIO DE PESO MOLECULAR ENTRE 60 Y 449, SI ES NECESARIO CON UTILIZACION DE EXPEDIENTES O PRODUCTOS ADITIVOS, EMPLEANDO EL AGUA EN UNA CANTIDAD DE POR LO MENOS 10 MOL%, RELATIVAMENTE A LA CANTIDAD MOLAR DE LOS GRUPOS ISOCIANATOS DE LOS POLI - ISOCIANATOS Y LLENANDO LA MEZCLA REACTIVA COMPUESTA DE LOS COMPONENTES EN UNA HERRAMIENTA ABIERTA, EN UN PROCESO DE MOLDE, LA CANTIDAD INTRODUCIDA REPRESENTANDO UN MINIMO DE 95% DEL VOLUMEN DE LA PARTE DEL MOLDE Y A CONTINUACION CERRANDO HERMETICAMENTE LA HERRAMIENTA DE TAL FORMA QUE EL DIOXIDO DE CARBON FORMANDOSE PRACTICAMENTE NO PUEDE LLEVAR A UNA EXPANSION DE LA MEZCLA REACTIVA.
