Abstract

"MéTODO MELHORADO PARA A FABRICAçãO DE PIGMENTO DURáVEL, DE ALTA OPACIDADE". A presente invenção refere-se a um pigmento de dióxido de titânio melhorado que incorpora um revestimento de sílica densa e seu processo para fabricação. O pigmento é preferivelmente produzido a partir de uma base de titânia do processo com cloreto em que o processo de fabricação compreende as etapas seguintes na ordem relatada: (a) remoção parcial ou substancial de sal a partir da descarga de oxidante; (b) adição de um dispersante; (c) fresagem para produzir uma suspensão altamente desaglomerada, altamente dispersa, seguida por tratamento de superfície com sílica densa. Os pigmentos preparados usando o processo inventivo exibem ópticas equivalentes aos pigmentos de alta opacidade, de alto brilho e mantém a durabilidade dos pigmentos tratados com sílica densa mais convencionais.
