Abstract

EN EL PROCESO SEGUN LA INVENCION PARA LA FABRICACION DE UNA ESPUMA DE SILICONA DE ALTO VALOR EN UN PROCESO DE FORMACION DE ESPUMA LIBRE, SE UTILIZA UN SISTEMA DE DOS COMPONENTES DE ADICION RETICULADORES, COMPUESTO DE UN COMPONENTE A, QUE CONTIENE POLIMERO DE SILICONA CON AL MENOS DOS ENLACES DOBLES POR MOLECULA (CON PREFERENCIA GRUPOS VINILO), UN CATALIZADOR DE PLATINO ORGANICO COMPLEXIONADO CON BUTINOL, ACIDO SILICICO PIROGENO Y AGUA, ASI COMO EVENTUALMENTE OTRAS SUSTANCIAS ADICIONALES, Y UN COMPONENTE B, QUE CONTIENE UN POLIMERO DE SILICONA CON AL MENOS DOS ENLACES DOBLES POR MOLECULA (CON PREFERENCIA GRUPOS VINILO), ACIDO SILICICO PIROGENO Y POLIDIMETILHIDROGENO SILOXANO COMO RETICULADOR SIH. AMBOS COMPONENTES SON MEZCLADOS, SOBRE CUYA MEZCLA DE REACCION EN UN RECIPIENTE DE RESERVA O SIMILAR, SE IMPULSA DURANTE VARIAS HORAS GAS A PRESION (CON PREFERENCIA AIRE A PRESION O NITROGENO), DE MODO QUE EL GAS SE ENCUENTRA EN LA MEZCLA EN FORMA DISUELTA. A CONTINUACION LA MEZCLA DE REACCION, CONPREFERENCIA A TRAVES DE APLICACION SUPERFICIAL CON ESPESOR DE CAPA DESEADA, SE LLEVA AL CALENTAMIENTO PARA LA REACCION, CON LO QUE SE AJUSTA LA ESPUMA DE SILICONA HOMOGENEA DE POROS FINOS.
