(FR) COMPOSITES DE MICROPARTICULES INORGANIQUES ET/OU ORGANIQUES ET DE NANOPARTICULES DE CARBONATE DE CALCIUM
Abstract
(EN)
The present invention relates to composites, comprising inorganic and/or organic pigments and/or fillers in the form of microparticles, the surface of which is coated at least partially with finely divided nano-calcium carbonate with the help of binders based on copolymers comprising as monomers one or more diearboxylic acids and one or more monomers from the group of diamines, triamines, dialkanolamines or trialkanolamines, a method for producing such composites, aqueous slurries thereof and their use in papermaking or in the field of paint and plastic production and the use of the inventive binders for coating the micropartieles with iiano-calcium carbonate.
(FR)
La présente invention concerne des composites, comprenant des pigments et/ou des matières de remplissage inorganiques et/ou organiques sous forme de microparticules, dont la surface est enduite au moins en partie de carbonate de calcium nanométrique finement divisé à l'aide de liants à base de copolymères comprenant en tant que monomères un ou plusieurs acides dicarboxyliques et un ou plusieurs monomères du groupe des diamines, triamines, dialcanolamines ou trialcanolamines. L'invention concerne également un procédé de fabrication de tels composites, des pâtes aqueuses de ces composites et leur utilisation dans la fabrication du papier ou dans le domaine de la fabrication de peintures ou de plastiques, ainsi que l'utilisation des liants selon l'invention pour le revêtement des microparticules avec du carbonate de calcium nanométrique.
