Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA ELABORACION DE LACAS EN POLVO, EN DONDE SE HOMOGENEIZA UNA MEZCLA A PARTIR DE A) UN AGLOMERANTE COMPUESTO DE UNA RESINA SINTETICA QUE CONTIENE GRUPOS EPOXI O UNA MEZCLA DE RESINAS SINTETICAS CONTENIENDO GRUPOS EPOXI Y B) UN MEDIO DE RETICULACION QUE DISPONE DE UN COMPUESTO CONTENIENDO EN LA MEDIA ESTADISTICA AL MENOS DOS GRUPOS CARBOXIL Y AL MENOS UN GRUPO ANHIDRIDO ACIDO POR MOLECULA O UNA MEZCLA DE TALES COMPUESTOS EN SITUACION FUNDIDA. LA COLADA HOMOGENEIZADA ASI OBTENIDA SE PULVERIZA DESPUES DE ENFRIAMIENTO Y SOLIDIFICACION. LA INVENCION SER CARACTERIZA TAMBIEN, PORQUE A LA MEZCLA A BASE DE A) Y B) SE LA ADICIONA ANTES O DURANTE EL PROCESO DE HOMOGENEIZACION DE COLADA, C) UN POLIOL O UNA MEZCLA DE POLIOLES EN UNA CANTIDAD TAL, QUE SE ENCUENTRA PRESENTE POR CADA GRUPO ANHIDRIDO ACIDO DEL COMPONENTE B) 0,1 HASTA 0,9 GRUPOS HIDROXIL DEL COMPONENTE C).
