| description | L'invention fournit une suspension aqueuse d'une matière minérale, par exemple du carbonate de calcium, qui est préparée par broyage humide puis concentration après broyage en présence d'au moins un agent rhéologique R comprenant de l'acide phosphorique et un polymère P α-sulfoné qui est totalement ou partiellement neutralisé au moyen d'un ion monovalent. L'invention concerne également l'agent rhéologique R ainsi que l'utilisation de cette suspension minérale pour la préparation d'une charge de masse de papier ou d'une sauce de couchage de papier ou encore pour la préparation d'une composition de revêtement, par exemple une composition de peinture.
The invention provides an aqueous suspension of a mineral material, for example calcium carbonate, which suspension is prepared by wet grinding step followed by a concentration step in the presence of at least one rheological agent R comprising phosphoric acid and an α-sulfonated polymer P which is completely or partially neutralised by means of a monovalent ion. The invention also relates to the rheological agent R and to the use of this mineral suspension for preparing a mass filler for paper, for preparing a paper coating slip, or for preparing a coating composition, for example a paint composition. |
