METHOD OF PRODUCING ANTICORROSIVE PIGMENT Russian patent published in 2013 - IPC C09C1/02 C09C1/24

Abstract RU 2471835 C1

FIELD: chemistry.

SUBSTANCE: anticorrosive pigment is obtained from a mixture of pigment components of oxygen-containing metal compounds. The method of producing pigment involves heat treatment of the mixture and grinding the heat treated product. The anticorrosive pigment is produced from a suspension of its components. The anticorrosive pigment additionally contains a pigment inhibitor-component which is a waste from neutralisation baths of machinery production, with the ratio of components galvanic sludge: inhibitor-component equal to 1:1 (on iron and calcium oxides) based on calcium contained in the galvanic sludge.

EFFECT: obtaining cheap highly resistant anticorrosive pigments with a ferrite structure, obtained from galvanic sludge, and wide field of their use.
