Abstract

ESTA INVENCION SE REFIERE A UN METODO DE PRODUCCION DE ESPUMA ELASTOMERICA DE SILICONA DE BAJA DENSIDAD . EN ESTE METODO SE MEZCLAN POLIDIORGANOXILOXANOS TERMINADOS EN HIDROXILO O TERMINADOS EN VINILO O EN MEZCLAS DE AMBOS JUNTO CON AGUA PARA REACCIONAR CON DIFRURO DE SILICIO EN PRESENCIA DE UN CATALIZADOR DE PLATINO PARA LIBERAR HIDROGENO GASEOSO Y CREAR UNA ESPUMA QUE ENDURECE FORMANDO UNA ESPUMA SOLIDA. LA COMBINACION DE INGREDIENTES PERMITE LA MANUFACTURA DE ESPUMA SOLIDA DE SILICONA CON COMBINACIONES DE PROPIEDADES DIFERENTES DE LAS OBTENIDAS MEDIANTE METODOS ANTERIORES. LAS REALIZACIONES DE ESTA INVENCION TAMBIEN UTILIZAN PROESPUMANTES ESPECIFICOS Y ALCOHOLES ESPECIFICOS PARA MODIFICAR AUN MAS LAS PPROPIEDADES DE LAS ESPUMAS SOLIDAS PRODUCIDAS. EL METODO DE ESTA INVENCION PRODUCE UNA ESPUMA ELASTOMERICA DE SILICONA DE BAJA DENSIDAD, BAJO PRECIO DE COSTE, CON PROPIEDADES FISICAS QUE PERMITEN UTILIZARLA EN APLICACIONES DE ALMOHADILLADO Y SELLADO.
