  • Patent number: 10011731
    Abstract: The present invention consists of a process of preparation of at least one mineral matter and/or of at least one pigment, including a calcium carbonate made at once partially organophilic and partially hydrophilic, in which the carbonate is blended and/or ground and/or concentrated in an aqueous medium, in the presence of at least one salt of ethylene acrylic acid, one dispersing agent and/or one grinding aid agent, which is introduced before and/or during this treatment stage. Another object of the invention lies in the aqueous dispersions and suspensions of calcium carbonate thus obtained. They may be dried and the dry pigments obtained also constitute an object of the invention. Use of these aqueous dispersions and these dry pigments in the field of plastic, paints and paper constitutes another object of the invention.

  • Patent number: 7638017
    Abstract: The invention concerns a pigment, filler or mineral containing a natural calcium carbonate, treated with one of more providers of H3O+ ions and gaseous CO2, allowing a reduction in the weight of paper for a constant surface area without loss of physical properties when it is used as a pigment or coating filler for the said paper. In particular, the invention concerns a pigment, filler or mineral containing a natural calcium carbonate or dolomite or mixtures of talc and calcium carbonate, of kaolin and carbonate or carbonate alone or in combination with natural and/or synthetic fibres or similar, treated with one or more medium-strong or strong providers of H3O+ ions in the presence of gaseous CO2. Applications are particularly in the paper industry, obtaining in particular good sheet properties i.e. a reduction its weight for a given surface area.
