IRON OXIDE BASED BLACK GLOSSY PIGMENT AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a method for preparing an iron oxide-based gloss and, more specifically, to a method for preparing an iron oxide-based black glossy pigment with high yield using iron sulfate as a starting material through thermal synthesis without sintering, wherein the method comprises the steps of: preparing an iron sulfate dilution liquid; forming a suspension of flake substrates; titrating the substrate suspension with an aqueous inorganic salt solution and mixing the iron sulfate dilution liquid therewith, thereby coating an oxide layer on surfaces of the flake substrates.
