Abstract

PERFECCIONAMIENTOS INTRODUCIDOS ENLA FABRICACION DE LENTES OFTALMICAS LAMINADAS. COMPRENDE UNA LENTE DE VIDRIO EXTERNA (9) Y UNA HOJA POLIMERICA COMPUESTA (1), INTEGRAL, OPTICAMENTE TRANSPARENTE Y ORGANICA, PEGADA SOBRE LA MISMA. ESTANDO COMPUESTA DICHA HOJA POLIMERICA (1) POR UNA CAPA DELGADA DE POLIURETANO TERMOPLASTICO (14), PEGADO A DICHA LENTE DE VIDRIO (9) Y FORMADO A PARTIR DE UN DIISOCIANATO ALIFATICO Y DE UN DIOL DE POLIESTER DIACIDO ALIFATICO DE PESOS MOLECULARES ENTRE 500-4.000 Y POR UNA CAPA DE POLIURETANO TERMOGRAGUANTE (18), FORMADO POR UN ETER DE POLIGLICOL, COMBINACION DE EPOXIAL 1-2-PROPANO CON 2-2-BIS (HIDROXIMETIL)-1-BUTANOL CONTENIENDO EL 10,5-12 POR CIEN POR PESO DE HIDROXIDOS LIBRES. EL PEGADO DE DICHA LENTE DE VIDRIO, SE REALIZA A TEMPERATURAS ELEVADAS ENTRE 100-125º C Y PRESIONES ENTRE 12 A 18 BARES POR ENCIMA DE LA PRESION ATMOSFERICA, DURANTE DOCE A DIECIOCHO HORAS, CON ELLO SE REFUERZA LA ADHERENCIA Y SE ELIMINAN LAS INCLUSIONES DE GASES.
