SELF-BINDING PIGMENT HYBRID |
摘要 |
<p>The present invention relates to a process for preparing self-binding pigment particles comprising the following steps: a) providing an aqueous mineral pigment material suspension; b) providing at least one polymeric binder, wherein the binder comprises at least one modified polysaccharide having a degree of carboxylation in the range of 0.4 to 2.0 and having an intrinsic viscosity in the range of > 300 to 500 ml/g, c) mixing the binder of step b) with the aqueous mineral pigment material suspension of step a) and adjusting the solids content of the obtained suspension so that it is ‰¥ 45 to 95 wt.-%, preferably from 45 to 80 wt.-%, based on the total weight of the suspension, and d) grinding the aqueous mineral material suspension of step c).</p> |
