Abstract

The invention relates to the technology of obtaining polychromatic synthetic mineral pigments for the production of priming, oil-base and polygraphic paints and can be used at varnish-and-paint production enterprises.The mineral pigments for varnish-and-paint materials comprise a mixed complex of copper (II)-iron(III) and ferro(III)-ferri(II) hexacyanide of general formula CuII-FeIII{FeIII[FeII(CN)6]}2 with the dispersion of 0.05…0.20 µm at a copper and iron ratio of (0.05…0.90):(0.95…0.10).The process for producing mineral pigments includes addition to a suspension of winy adhesive precipitates containing Prussian blue of a calcium hydroxide solution, separation by electroflotation of solid impurities, purification of the solution containing water-soluble Prussian blue of general formula Ca{FeIII[FeII(CN)6]}2, treatment thereof with an ultrasonic field with the frequency of 20…40 kHz and the intensity of 1…3 W/cm3 during 5…10 min, addition of a stochiometric quantity of iron sulphate and copper sulphate solution at a pH of 2.5…3.0, separation of the obtained residue, washing, drying and milling thereof. As iron sulphate and copper sulphate source are used spent solutions of copper etching at the production of printed-circuit boards on base of ferric chloride.The result of the invention consists in producing mineral pigments with high parameters of dispersion, light- and chemical fastness, with the colour gamma from aquamarine up to reddish-brown.
