METHOD FOR PRODUCING PIGMENTARY PARTICLES THAT ARE SELF-BINDING, DRY, OR IN AN AQUEOUS SUSPENSION OR DISPERSION, AND CONTAIN INORGANIC MATERIALS AND BINDING AGENTS

摘要

The invention relates to a method for producing pigmentary particles that are self-binding, dry, or in an aqueous suspension or dispersion, and contain at least one inorganic material and at least one binding agent, said method comprising the following steps: a) at least one aqueous suspension of at least one inorganic material is formed and introduced into a grinder for step c), b) at least one aqueous solution or suspension or aqueous emulsion of at least one binding agent is formed or taken and introduced into a grinder for step c), c) the aqueous suspension(s) obtained in step a) are ground together with the at least one aqueous solution or suspension or emulsion obtained in step b) in such a way as to obtain an aqueous suspension of self-binding pigmentary particles, d) optionally the aqueous suspension or dispersion obtained in step c) can be ground with at least one aqueous solution or suspension or emulsion of at least one binding agent, e) optionally the aqueous suspension obtained in step c) or step d) can be dried, f) the concentration of the aqueous suspension obtained in step c) or d) is increased by a thermal or mechanical concentration method, and g) the aqueous suspension obtained in step f) is dispersed by means of at least one dispersant and/or at least one wetting agent.
