Abstract

SE PRESENTA UN PROCESO PARA ELABORAR MICROCAPSULAS DE MELAMINA-FORMALDEHIDO EN SOLUCION ACUOSA QUE CONTIENE UNA ALTA CONCENTRACION DE SOLVENTE ORGANICO HIDRO-MISCIBLE O HIDROSOLUBLE. LA SOLUCION ACUOSA SE PREPARA Y SE DISUELVE EN LA MISMA MELAMINA-FORMALDEHIDO PRECONDENSADA AJUSTANDO LA TEMPERATURA Y LA CONCENTRACION DE SOLVENTE ORGANICO DE LA SOLUCION ACUOSA DE MANERA QUE LA MELAMINA-FORMALDEHIDO PRECONDENSADA SEA APENAS SOLUBLE EN LA MISMA. SE DISPERSA UNA SUBSTANCIA A ENCAPSULAR, PREFERIBLEMENTE UNA SOLUCION ACEITOSA QUE CONTENGA UN PRECURSOR DE TINTE, EN LA SOLUCION ACUOSA PARA FORMAR UNA EMULSION, SIENDO LA MELAMINA-FORMALDEHIDO PRECONDENSADA INSOLUBLE EN LA SUBSTANCIA A ENCAPSULAR. LA MELAMINA-FORMALDEHIDO PRECONDENSADA SE SEPARA DE LA SOLUCION ACUOSA EN GOTAS DE LA SOLUCION A ENCAPSULAR Y LA REACCION DE AUTO-CONDENSACION Y LA MELAMINA-FORMALDEHIDO PRECONDENSADA SEPARADA DE FASE INICIADA PARA FORMAR PAREDES DE CAPSULA ALREDEDOR DE LAS GOTA, PRODUCIENDO ASI MICROCAPSULAS DE MELAMINA-FORMALDEHIDO EN LA SOLUCION ACUOSA QUE CONTIENE ALTA CONCENTRACION DE UN SOLVENTE ORGANICO HIDRO-MISCIBLE O HIDROSOLUBLE.
