Abstract
PROCEDIMIENTO PARA EL AISLAMIENTO POR IMPREGNACION DE CONDUCTORES ELECTRICOS POR MEDIO DE RESINAS CON CICLOS ISOCIANURATOS Y OXAZOLIDONAS.SE ENROLLA ALREDEDOR DE LOS CONDUCTORES UNA CINTA DE TEJIDO DE VIDRIO Y DE PAPEL DE MICA POROSO, SE IMPREGNA LA CINTA CON UNA SAL DE AMONIO CUATERNATIO QUE CATALIZA LA CONDENSACION DE DERIVADOS ISOCIANATOS Y EPOXI EN CICLOS ISOCIANURATOS Y OXAZOLIDONAS Y DE UN BARNIZ QUE COMPRENDE UNA RESINA EPOXI LIQUIDA Y UN DERIVADO ISOCIANATO, Y A CONTINUACION SE SOMETE LA CINTA IMPREGNADA A UN TRATAMIENTO TERMICO DE POLIMERIZACION DEL BARNIZ. SE EMPLEA COMO SAL DE AMONIO CUATERNARIO UN HALOGENURO DE BENCILTRIALQUILAMONIO CON CADENA ALQUILO QUE CONTIENE COMO MAXIMO 3 ATOMOS DE CARBONO, SE IMPREGNA LA CINTA EN PRIMER LUGAR CON HALOGENURO DE BENCILTRIALQUILAMONIO Y CON LA RESINA EPOXI LIQUIDA, SE SECA A UNA TEMPERATURA COMO MAXIMO IGUAL A 135JC Y, A CONTINUACION, SE IMPREGNA CON UN BARNIZ A BASE DE DERIVADO ISOCIANATO, ANTES DE SOMETER LA CINTA AL TRATAMIENTO TERMICO DEPOLIMERIZACION.
