Abstract

METODO PARA LA PREPARACION DE ELASTOMEROS DE POLIURETANO REFORZADOS CON FIBRAS INERTES. CONSISTENTE EN LA REACCION DE DOS CORRIENTES, UNA DE LAS CUALES CONTIENE UNA POLIISOCIANATO Y LA OTRA MATERIALES CON HIDROGENO ACTIVO. EL POLIISOCIANATO PUEDE SER METILENBIS (4-FENILISOCIANATO) Y EL MATERIAL CON HIDROGENO ACTIVO PUEDE SER UN POLIOL CON PESO MOLECULAR DE 5.500 APROXIMADAMENTE. EL METODO SE CARACTERIZA POR INTRODUCIR LA TOTALIDAD DEL MATERIAL DE CARGA INERTE EN LA CORRIENTE DE ISOCIANATO ANTES QUE ESTA SE MEZCLE Y REACCIONE CON LA CORRIENTE QUE CONTIENE HIDROGENO ACTIVO. LOS MATERIALES REFORZANTES PUEDEN SER FIBRAS DE VIDRIO CORTADAS O MACHADAS Y/U OTRAS FIBRAS MINERALES. LA REACCION DE AMBAS CORRIENTES TIENE LUGAR EN LA FORMA CONVENCIONAL, OBTENIENDOSE EN ELASTOMERO QUE SE ENDURECE A 121 C. DURANTE UNOS TREINTE MINUTOS.
