Abstract

"PROCESSO DE PREPARAçãO DE SìLICA PRECIPITADA, CONTENDO O ALUMìNIO". A presente invenção refere-se um processo de preparação de uma sílica do tipo que compreende a reação de um silicato com um agente acidificante, pelo que se obtém uma suspensão de sílica precipitada, depois a separação e a secagem dessa suspensão, caracterizado pelo fato desse processo compreender a seguinte operação: acrescenta-se ao meio reacional pelo menos um composto A do alumínio, depois se acrescenta ao meio reacional um agente acidificante, essa separação comportando uma filtragem e uma desagregação do bolo proveniente dessa filtragem, essa desagregação sendo, de preferência, feita em presença de pelo menos um composto B do alumínio. As sílicas assim preparadas são particularmente bem adaptadas a uma utilização como carga reforçadora para os elastómeros.
