Title:
天然炭酸カルシウムおよびアクリル酸-エチレンの塩に基づく粒子の製造方法、得られる乾燥顔料、ならびにそれらの使用
Document Type and Number:
Japanese Patent JP5384116
Kind Code:
B2
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.
