Title (EN) DISPERSION AND/OR GRINDING AGENT FOR AQUEOUS MINERAL SUSPENSIONS WITH A ZETA POTENTIAL CLOSE TO ZERO, AQUEOUS SUSPENSIONS CONTAINING SAME, AND APPLICATIONS
(FR) AGENT DE DISPERSION ET/OU DE BROYAGE POUR SUSPENSIONS AQUEUSES MINERALES DE POTENTIEL ZETA VOISIN DE ZERO, SUSPENSIONS AQUEUSES LE CONTENANT ET APPLICATIONS
Abstract:
(EN) Water-soluble, amphoteric grinding and/or dispersion agent for aqueous mineral suspensions with the formula (I) having the general form: -(A)p-(B)q-(C)r, where (A) is an anionic ethylene monomer with carboxylic function, (B) is a non-ionic ethylene monomer, (C) is a cationic ethylene monomer comprising at least two oxyalkyl groups, and where: p ranges from 35 to 65 % by weight with respect to the total weight of monomers; q ranges from 20 % to 60 % by weight with respect to the total weight of monomers; r ranges from 5 % to 20 % by weight with respect to the total weight of monomers; and p + q + r = 100 % of the total weight of monomers. The described agent provides for the preparation of aqueous suspensions of mineral fillers and/or pigments with a zeta potential close to 0, a concentration at least equal to 50 % by weight of dry matter, which are suitable for use in the fields of paper, paints and plastic materials.
(FR) Agent amphotère, hydrosoluble, de broyage et/ou de dispersion pour suspensions aqueuses minérales, de formule (I) de forme générale: -(A)p-(B)q-(C)r dans laquelle le motif (A) est un monomère éthylénique anionique à fonction carboxylique, le motif (B) est un monomère éthylénique non ionique, le motif (C) est un monomère éthylénique cationique comprenant au moins deux groupements oxyalkylés, et dans laquelle, bornes incluses: a) p prend une valeur comprise entre 35 % et 65 % en poids par rapport à la masse totale en monomères, b) q prend une valeur comprise entre 20 % et 60 % en poids par rapport à la masse totale en monomères, c) r prend une valeur comprise entre 5 % et 20 % en poids par rapport à la masse totale en monomères, d) avec p + q + r = 100 % de la masse totale en monomères. L'agent selon l'invention permet la préparation de suspensions aqueuses de charges minérales et/ou de pigments, de potentiel zéta voisin de 0, de concentration au moins égale à 50 % en poids de matière sèche avantageusement utilisées dans le domaine papetier, le domaine des peintures et le domaine des matières plastiques.
