The invention relates to aqueous suspensions of fine-particulate fillers that are at least partially lined with anionic lattices, wherein the suspensions are obtained from the treatment of aqueous suspensions of fine-particulate fillers with an aqueous dispersion comprising at least one anionic latex and at least one decomposed starch, to preparation of the aqueous suspensions and to the use thereof as additives to paper materials in the production of paper, carton, or corrugated cardboard that contains fillers, said preparation done by dewatering the paper materials.
Suspensions aqueuses de matières de charge fines recouvertes au moins partiellement de micelles anioniques, ces suspensions étant obtenues par traitement de suspensions aqueuses de matières de charge fines avec une dispersion aqueuse contenant au moins un latex anionique et au moins un amidon décomposé. L'invention porte également sur la fabrication des suspensions aqueuses et sur leur utilisation en tant qu'additifs de la pâte à papier lors de la fabrication de papier, de carton ou de carton-pâte contenant des matières de charge et obtenus par égouttage de la pâte à papier.
