Abstract

PROCEDIMIENTO PARA LA FABRICACION DE ESPUMAS DE POLIURETANO. TIENE COMO OBJETO MEJORAR LAS CONDICIONES DE INFLAMABILIDAD DE TALES ESPUMAS MEDIANTE LA ADICION DE ADITIVOS A LAS MEZCLAS DE REACCION FORMADORAS DE LAS MISMAS. LAS MEZCLAS DE REACCION UTILIZADAS SON POLIOL-POLIESTER Y POLI-SOCIANATO ORGANICO, REALIZANDOSE LA MISMA EN PRESENCIA DE UN AGENTE DE SOPLADO. EN ESTE PROCEDIMIENTO SE LE AÑADE A LA MEZCLA UN ALDEHILO ALIFATICO EN CANTIDAD SUFICIENTE PARA REDUCIR LA FORMACION DE ASCUAS, ASI COMO UN RETARDANTE DE LA LLAMA, SELECCIONADO DEL GRUPO CONSTITUIDO POR ESTERES DE ACIDO FOSFORICO, ESTERES HALOGENADOS DE ACIDO FOSFORICO E HIDROCARBUROS HALOGENADOS. SE UTILIZAN COMO CAPA BASE DE ALFOMBRAS, REVESTIMIENTOS INTERIORES DE PRODUCTOS TEXTILES Y PARA AISLAMIENTO.
