Abstract
EL LIQUIDO ELECTROVISCOSO SE BASA EN UNA SUSPENSION QUE CONTIENE MAS DE UN 25% DE UN SILICATO DE ALUMINIO, CON UN CONTENIDO DE AGUA DEL 1 AL 25% EN PESO, COMO FASE DISPERSA, Y UN LIQUIDO HIDROFOBO, QUE NO CONDUCE LA CORRIENTE ELECTRICA, COMO FASE LIQUIDA, EN UNION CON UN AGENTE DISPERSANTE. PARA ELLO SE EMPLEAN SILICATOS DE ALUMINIO, EN LOS QUE LA RELACION ATOMICA AL/SI EN LA SUPERFICIE SE ENCUENTRA ENTRE 0,15 Y 0,80. COMO FASE LIQUIDA SE EMPLEA ACEITE DE SILICONA, AL QUE SE HAN A/ADIDO AGENTES DISPERSANTES DE POLISILOXANOS CON FUNCIONES AMINO O HIDROXI O ACETOXI O ALCOXI, DE UN PESO MOLECULAR MAYOR DE 800. EN UN LIQUIDO ELECTROVISCOSO DE ESTE TIPO, SE CONSERVA LA ELECTRORREACTIVIDAD, INCLUSO A TEMPERATURAS ALTAS, SIN QUE AUMENTE ESENCIALMENTE LA CONDUCTIVIDAD ELECTRICA FIGXX.
