PROCEDE DE FABRICATION DE PARTICULES PIGMENTAIRES AUTOLIANTES, SECHES OU EN SUSPENSION OU DISPERSION AQUEUSES, CONTENANT DES MATIERES INORGANIQUES ET DES LIANTS

摘要

The present invention is directed to a process for the preparation of an aqueous suspension of self-binding pigmentary particles comprising the following stages: (a) forming one or more aqueous suspensions of at least one inorganic matter comprising calcium carbonate; (b) forming or obtaining one or more aqueous solutions or suspensions or emulsions of at least one binder; and (c) co-grinding the aqueous suspension or suspensions obtained in stage a) with the aqueous solutions or suspensions or emulsions obtained in stage b) in a mill so as to obtain an aqueous suspension of self-binding pigmentary particles.
