Abstract

"PREPARAçãO E UTILIZAçãO DE OPACIFICADORES MISTOS à BASE DE óXIDOS DE TITâNIO E DE SILìCIO" A presente invenção se refere a um processo para a preparação de uma composição à base de TiO~ 2~, utilizável como agente opacificador, compreendendo a misturação a uma dispersão aquosa de TiO~ 2~ de uma dispersão aquosa de pelo menos um agente espaçador inorgânico, em condições suficientes para que as duas espécies minerais se arranjem em flocos minerais mistos, em que as partículas de TiO~ 2~ estão globalmente espaçadas entre si pelas partículas e/ou agregados de agente espaçador. Também se refere a uma composição à base de TiO~ 2~ e de SiO~ 2~ caracterizada pelo fato de as partículas de TiO~ 2~ e de SiO~ 2~ estarem arranjadas sob a forma de flocos minerais mistos à base de TiO~ 2~ e de SiO~ 2~, em que as partículas de TiO~ 2~ estão globalmente isoladas umas das outras por agregados de sílica, e sua utilização como agente opacificador, particularmente na indústria do papel."PREPARATION AND USE OF TITANIUM AND SILICON OXIDES MIXED OPACIFICATORS" The present invention relates to a process for the preparation of a composition based on TiO ~ 2 ~, usable as an opacifying agent, comprising mixing with a dispersion aqueous solution of TiO ~ 2 ~ from an aqueous dispersion of at least one inorganic spacer, under conditions sufficient for the two mineral species to be arranged in mixed mineral flakes, in which the TiO ~ 2 ~ particles are globally spaced apart by the particles and / or spacing agent aggregates. It also refers to a composition based on TiO ~ 2 ~ and SiO ~ 2 ~ characterized in that the particles of TiO ~ 2 ~ and SiO ~ 2 ~ are arranged in the form of mixed mineral flakes based on TiO ~ 2 ~ and SiO ~ 2 ~, where TiO ~ 2 ~ particles are globally isolated from each other by aggregates of silica, and their use as an opacifying agent, particularly in the paper industry.
