Abstract

Se describe un procedimiento para la producción en continuo de espuma en bloque de poliuretano con empleo de dióxido de carbono disuelto dísicamente apresión como agente expansionante, en el que el dióxido de carbono se disuelve en el componentepoliol antes de la mezcla de los componentes poliol eisocianato y se disuelve aire o nitrógeno en el componente isocianato, se dirigen ambos componentes a una camára mezcladora en la que reina una presiónque está comprendida entre el 70 y el15 0% de la presión de disolución del CO2 en el componente poliol, se dirige el componente isocianato a la cámaramezcladora a una presión de, por lo menos, 30 barias y se inyecta en la cámara mezcladora con expansión en está, disolviéndose en elcompo nente isocianatoaire o nitrogeno en una proporción de 1 g por kg de CO2 y la mezcla, después de la salida de la cámara mezcladora, se expansiona hasta la presión atmosférica.
