Abstract

METODO DE TRATAMIENTO DE RESINAS EPOXIDICAS QUE CONTIENEN HALURO HIDROLIZABLE. CONSISTE EN DISOLVER LA RESINA EPOXIDICA EN UN DISOLVENTE CONSTITUIDO POR 25 A 75% DE AL MENOS UNA CETONA Y 75 A 25% DE AL MENOS UN HIDROCARBURO AROMATICO; AÑADIR 0,1 A 5%, RESPECTO DEL PESO DE LA RESINA, DE UN COMPUESTO QUE TIENE AL MENOS UN GRUPO HIDROXILO ALIFATICO Y CALENTAR A UNA TEMPERATURA COMPRENDIDA ENTRE 50JC Y 200JC EN PRESENCIA DE UN HIDROXIDO DE METAL ALCALINO. LAVAR EL PRODUCTO RESULTANTE CON AGUA O DISOLUCION ACUOSA ACIDA, Y RECUPERAR LA RESINA. ESTAS RESINAS TIENEN APLICACIONES EN LA INDUSTRIA ELECTRONICA COMO AGENTES DE ENCAPSULACION, COMPUESTOS DE RELLENADO, ESTRATIFICADOS ELECTRICOS Y SIMILARES.43
