Abstract

PROCEDIMIENTO PARA LA OBTENCION DE CUERPOS MOLDEABLES A BASE DE POLIURETANO. SE HACE REACCIONAR UN COMPUESTO POLIHIDROXILICO CON POLIISOCIANATOS ORGANICOS EN PROPORCIONES CUANTITATIVAS CORRESPONDIENTES A UNA RELACION DE EQUIVALENCIA DE NCO/OH DE 0,8:1 HASTA 1,2:1 LA MEZCLA OBTENIDA POR COMBINACION DE LOS REACTANTES SE HACE REACCIONAR A UNA TEMPERATURA ENTRE 0 Y 100GC PARA OBTENER UN PRODUCTO SOLIDO, PULVERIZABLE Y FUNDIBLE QUE CONTIENE GRUPOS ISOCIANATOS E HIDROXILOS LIBRES; ESTABLE EN EL MARGEN DE TEMPERATURAS INDICADO. EN LA PRIMERA PARTE DEL PROCESO PUEDEN EMPLEARSE, OPCIONALMENTE, AGENTES AUXILIARES Y ADITIVOS. COMO COMPUESTO POLIHIDROXILICO SE PUEDE UTILIZAR, ENTRE OTROS, UN PRODUCTO DE ALCOXILACION DEL AMONIACO DOTADO DE TRES GRUPOS HIDROXILO, DE PESO MOLECULAR SUPERIOR A 148 Y CON CONTENIDO EN GRUPOS HIDROXILOS DE, COMO MINIMO, UN 12 POR 100 EN PESO. SE PRESENTAN OTRAS VIAS ALTERNATIVAS PARA EL PROCEDIMIENTO DE OBTENCION. LOS CUERPOS OBTENIDOS SON MOLDEABLES Y AISLANTES, POR LO QUE SON DE EMPLEO EN LA INDUSTRIA ELECTRICA. E
