Abstract

Proceso para preparar una espuma de poliuretano flexible a un índice de NCO de 70-120 por reaccion de a) una composicion de poliisocianato comprendiendocada 100 partes en peso de composicion 5 a 20 partes en peso de tolilén disocianato y80-9 5 partes en peso de difenilmetano diisocianato y homologosdel mismo con una funcionalidad de isocianato de 3 o más, la cantidad de difenilmetano diisocianato es de 70 a 95% en peso calculada sobre la cantidadde difenilmetanodiisocianatos y ho mologos, y el difenilmetano diisocianato comprende 8-45% en peso calculado sobre el peso de este difenilmetanodiisocianato, de difenilmetano diisiocianato que contiene por lo menos un grupo NCO en la posicion orto; b) unacomposicion de poliol qu e comprende: 1) unpolioxietilén-polioxipropilén-poliol, con una funcionalidad hidroxilo nominal promedio de 2-6, un peso equivalente promedio de 1000-4000 y 5-25% en peso degrupos oxietileno; 2) 2 a 7 partes en peso deagua; 3) 2 a 10 partes en pes o de un poliéter poliol que contiene una funcionalidad hidroxilo nominal promedio de2-6, un peso equivalente promedio de 200-1500 y por lo menos 60% en peso de grupos oxietileno; 4) 1 a 15 partes en peso de materialen partículas el cuales el pro ducto de reaccion de un poliisocianato y un compuesto que tiene una pluralidad de grupos hidroxilo-, amina primaria y/o amina secundaria y un pesoequivalente de hasta 400 y el cual está disperso en dicha composicionde poliol; las cantidade s de b2) a b4) están calculadas por cada 100 partes enpeso de b1); y 5) opcionalmente auxiliares y aditivos conocidos per se. Se obtienen espumas moldeadas de baja densidad las cuales muestran unaaltaelasticidad, curado rápido, cortos tiempos d e desmolde y buenas propiedades de resistencia a las cargas, al desgarro, elongacion, confort y durabilidad.
