Abstract

FABRICACION DE MICROCAPSULAS DE 1 A 20 MICRAS, DE PAREDES POLIMERICAS, GENERALMENTE CONTINUAS, EN TRES ETAPAS QUE COMPRENDEN: A)PREPARACION DE UNA PRIMERA EMULSION ACUOSA DE UN COMPONENTE ORGANICO, FORMADA POR UNA PRIMERA SOLUCION ORGANICA DE UN POLIISOCIANATO, Y UNA PRIMERA SOLUCION ACUOSA DE EMULSIFICACION; B)PREPARACION DE UNA SEGUNDA EMULSION ACUOSA DE UN COMPONENTE ORGANICO, FORMADA POR UNA SEGUNDA SOLUCION ORGANICA DE UN SEGUNDO MATERIAL REACTIVO SOLUBLE EN ACEITE, QUE ES UNA AMINA, Y UNA SEGUNDA SOLUCION ACUOSA DE EMULSIFICACION; C)MEZCLA DE DICHAS EMULSIONES ACUOSAS DE COMPONENTES ORGANICOS, DE MODO QUE REACCIONEN ENTRE SI LOS MATERIALES REACTIVOS SOLUBLES EN ACEITE PARA FORMAR DICHAS MICROCAPSULAS Y ENCAPSULAR EL CITADO PRIMER MATERIAL REACTIVO SOLUBLE EN ACEITE. EL POLIISOCIANATO ESTA EN EXCESO ESTEQUIOMETRICO CON RESPECTO A LA AMINA. LAS APLICACIONES DE LAS MICROCAPSULAS SON TAN VARIADAS COMO PUEDAN SERLO LOS MATERIALES MICROENCAPSULADOS: PREPARACIONES BIOLOGICAS Y MEDICINALES, FERTILIZANTES, AROMATIZANTES, DESODORANTES, ADHESIVOS, SISTEMAS DE COPIA, ETC.
