Abstract

PROCEDIMIENTO PARA LA FABRICACION DE MICORCAPSULAS PARA PAPEL REGISTRADOR SENSIBLE A LA PRESION. CONSISTENTE EN PROCEDER EN UNA PRIMERA FASE A LA DISPERSION DE UNA SOLUCION FORMADORA DE COLOR EN UNA MEZCLA ACUOSA EN LA QUE SE ENCUENTRAN PRESENTES COMO MINIMO UNA RESINA DE UREA CATIONICA SOLUBLE EN AGUA Y UN AGENTE TENSOACTIVO ANIONICO, PROCEDIENDOSE POR MEDIOS ADECUADOS, TALES COMO UN HOMOGENEIZADOR AGITADOR O DISPOSITIVO DE ULTRASONIDOS, DE MODO QUE EL DIAMETRO DE LA GOTICULA DE LIQUIDO TIENE UN VALOR APROXIMADO DE 1 A 8 UM. A AL DISPERSION ACUOSA SE AÑADE UN PREPOLIMERO A BASE DE MELAMINA Y/O UREA Y FORMALDEHIDO. LA FORMACION DE LA PARED PARA LA MICROCAPSULA SE CONSIGUE POR LA POLICONDENSACION DEL PREPOLIMERO Y DE LA RESINA DE UREA CATIONICA SOLUBLE EN AGUA SOBRE LA SUPERFICIE DE UNA GOTICULA DEL DISOLVENTE, AJUSTANDO EL PH DE LA SOLUCION ACUOSA EN CONDICIONES ACIDAS.
