Method and device for producing printing inks

一种制造印刷油墨或浓缩物的方法，包括以下顺序的步骤：向第一加工区加入含有亲油有色颜料的含水浆液和亲油粘结剂；在第一加工区，对加入到第一加工区的含水有色颜料浆液和粘结剂施加剪切流和外延流，以便至少部分从含水浆液中冲洗出的亲油有色颜料与亲油粘结剂结合；在第一加工区下游第一次除去源于含水浆液的水；来自第一加工区的部分脱水自由流动物质被送到第二加工区，并在那里自由流动物质暴露于剪切、外延和压缩作用下，而且通过第一加工区的部分冲洗作为分离相释放的水被第二次从自由流动物质中除去；基本上不含水且亲油有色颜料分散在亲油粘结剂中的自由流动物质被移走并且作为中间产物或者最终产物收集。 The invention relates to a method for producing a printing ink or a printing ink concentrate. The inventive method includes the following steps that are successively carried out: an aqueous slurry that contains lipophilic coloring pigments and a lipophilic binder is fed to a first treatment area; the aqueous coloring pigment slurry and the binder that have been fed to the first treatment area are subjected in the first treatment area to shearing and extensional flows so that an at least partial flushing of the lipophilic coloring pigments from the aqueous slurry with the lipophilic binder takes place; downstream of the first treatment area water stemming from the aqueous slurry is removed for the first time; the partially dehydrated flowable mass obtained in the first treatment area is fed to a second treatment area in which the flowable mass is subjected to shearing, extensional and compressive effects; water released as a separate phase in the first treatment area is removed from the flowable mass for the second time by way of partial flushing; the substantially dehydrated flowable mass in which the lipophilic coloring pigments are dispersed in the lipophilic binder is removed as an intermediate or final product and collected.
