Abstract

PARA LA FABRICACION DE PARTES DE MOLDE DE ESPUMA DE SILICONA CON POROS FINOS DE ALTO VALOR EN PROCESOS DE FUNDICION DE INYECCION SE UTILIZAN DOS COMPONENTES A/B DE REACCION, CONTENIENDO AMBOS POLIMERO SILICONA Y ACIDO SILICICO PIROGENO, CON LO QUE EL COMPONENTE A CONTIENE ADICIONALMENTE UN CATALIZADOR DE PLATINO ORGANICO COMPLEXIONADO CON BUTINOL, ASI COMO UNA CANTIDAD DE AGUA PEQUEÑA, MIENTRAS QUE EL OTRO COMPONENTE B CONTIENE SILOXANO POLIDIMETILHIDROGENO COMO RETICULADOR. AL MENOS UNO DE AMBOS COMPONENTES A/B SE IMPULSA EN LA MEZCLA EN UN RECIPIENTE A PRESION O SIMILAR CON GAS A PRESION (CON PREFERENCIA A Y B O NITROGENO), DE FORMA QUE EL GAS SE DISUELVE EN EL COMPONENTE. LOS COMPONENTES A/B SE MEZCLAN ENTONCES BAJO PRESION Y SE INYECTAN EN EL MOLDE DE INYECCION Y DE AQUI SE CALIENTAN, DE FORMA QUE SE PRODUCE LA ESPUMA BAJO LA FORMACION DE LAS PARTES DE MOLDE DE ESPUMA DE SILICONA.
