SUSPENSION OF SELF-BINDING PARTICLES, METHOD OF ITS PRODUCTION AND USE Russian patent published in 2016 - IPC C09C1/02 C09C3/10 C09C3/04 C08K3/26 D21H17/69 D21H19/38 A01N59/06 C04B14/28 

FIELD: chemistry.

SUBSTANCE: invention can be used in production of paper, plastic, paints, coatings, concrete, in agriculture. Method of producing self-binding pigment particles includes providing a suspension containing at least one material containing calcium carbonate, an anionic polymer binding agent and at least one cationic polymer. Said binder contains at least one modified polysaccharide. Suspension and the binding agent are mixed and milled. Binding agent is added in the amount from 0.001 to 20 wt%. Cationic polymer in the amount from 0.001 to 20 wt% is mixed with the suspension and the binding agent and/or mixed with the suspension obtained when milling. Obtained mixture is subjected to deagglomeration cycles.

EFFECT: invention allows improving retention of the filler in paper production, producing paper with high content of the filler without disturbing its mechanical and optical properties.
