UTILISATION DE POLYMERES ACRYLIQUES PEIGNE AVEC DES GROUPES HYDROPHOBES COMME AGENTS DE COUPLAGE DANS UN PROCEDE DE BROYAGE DE MATIERES MINERALES AVEC DES LIANTS.

摘要

The invention pertains to the use as a coupling agent, in a method for manufacturing self-binding particles by grinding at least one latex binder and at least one mineral material in an aqueous medium, of an aqueous solution of a fully or partially acidic water-soluble copolymer, present during the step of grinding, wherein the copolymer is made up of at least one ethylenically-unsaturated anionic monomer, and at least one ethylenically-unsaturated oxyalkylated monomer terminated by a hydrophobic alkyl, alkylaryl, arylakyl, or aryl chain having 10 to 32 carbon atoms.
