Abstract

The invention relates to printing ink powder and a preparation method therefor, and belongs to the technical field of ink powder preparation. The printing ink powder is prepared from the following components by weight: 30-40 parts of Fe3O4 powder, 10-15 parts of modified starch, 10-20 parts of styrene-acrylic resin, 1-5 parts of talcum powder, and 1-5 parts of sodium silicate. The preparation method comprises: uniformly mixing the Fe3O4 powder, the modified starch, the talcum powder and sodium silicate, and ball-milling for 30-35 minutes; adding 100-110 parts by weight of de-ionized water, then adding the styrene-acrylic resin, heating to 50-56 DEG C, and keeping the temperature for 60-75 minutes; washing a mixture with de-ionized water 10-12 times heavier than the mixture, filtering the washed mixture, and drying the filtered mixture into granular materials; and screening the materials, selecting granules of 2-10 microns, and drying the granules at 60-65 DEG C for 30-40 minutes to obtain the printing ink powder. The ink powder is regular and uniform in granule shape, clear in development imaging, free of bottom ash, suitable for use in various different machines, relatively low in preparation cost, and easy for industrialized.
