Abstract

LAS DISPERSIONES O EMULSIONES ACUOSAS DE POLIACRILATO HABITUALES CONCENTRADAS LIBRES DE DISOLVENTES TIENEN EN GENERAL UN PH ALTAMENTE ACIDO DE 2 A 3,5, DE MODO QUE MUESTRAN PROPIEDADES FUERTEMENTE CORROSIVAS FRENTE A OBJETOS DE METAL QUE HAY QUE PROTEGER. LAS NUEVAS DISPERSIONES DE POLIACRILATO Y LOS RECUBRIDORES EN CAPAS QUE LAS CONTIENEN MUESTRAN FRENTE A ESTO UN PH POCO ACIDO DE 4 A 6. LAS DISPERSIONES DE POLIACRILATO CON EL PH POCO ACIDO MENCIONADO ARRIBA SE CONSIGUEN NEUTRALIZANDO ANTES DE LA COPOLIMERIZACION LOS COMONOMEROS PORTADORES DE GRUPOS CARBOXILO CON COMONOMEROS HIDROFOBOS A 5 - 50 MOL% CON UNA BASE. LAS DISPERSIONES DE POLIACRILATO OBTENIDAS DE ESTA FORMA SE SECAN SOBRE LOS OBJETOS FORMANDO PELICULAS TRANSPARENTES LAVABLES QUE SE PUEDEN ELIMINAR FACILMENTE CON MEDIOS ALCALINOS. GRACIAS A SU PH DE 4 A 6 SON MUCHO MENOS CORROSIVAS FRENTE A LOS OBJETOS A PROTEGER. LAS DISPERSIONES O EMULSIONES ACUOSAS DE POLIACRILATOS ENCUENTRAN UTILIDAD COMO MEDIOS DE REVESTIMIENTO EN CAPAS PARA PROTECCION SUPERFICIAL TEMPORAL DE SUPERFICIES METALICAS Y/O LACADAS, EN ESPECIAL CARROCERIAS DE AUTOMOVILES, FRENTE A INFLUENCIAS CLIMATICAS Y/O MECANICAS.
