More Information
Summary:The invention discloses an iron oxide black pigment used for printing ink, which is prepared from following raw materials, by weight, 80-100 parts of modified iron oxide black, 5-10 parts of graphite powder, 1-2 parts of hydroxyethyl cellulose, 6-8 parts of sodium silicate, 0.1-0.2 parts of azodiisobutyronitrile, 0.1-0.2 parts of starch sodium octenyl succinate, 10-15 parts of styrene, 1-2 parts of microcrystalline wax and 1-2 parts of glycerol triacetate. The iron oxide black pigment has strong tinting strength, is excellent in temperature and weather resistance, is easy to disperse, is good in processing performance, is strong in adhesive fastness, is not liable to fall off, is good in abrasion resistance and use performances, and is suitable for printing ink pigments.
