FIELD: metal-protecting materials. ^ SUBSTANCE: invention relates to protection of metals against corrosion using paint and varnish coatings. Invention proposes using as anticorrosive pigments co-precipitated manganite-phosphates, manganite-silicates, manganite-sulfates of metals of the general formula: MMnOxnMZ wherein M means Ca2+, Zn2+, Fe2+, Sr2+ at Z - PO4 3-, SiO3 2-, and M means Ba2+ at Z - SO4 2-, PO4 3-, SiO3 2-; x = 2.5-3; n = 0.5-10 with the content of co-precipitated manganite of corresponding metal from 5 to 70 wt.-% as anticorrosive pigments. Proposed pigments by their anticorrosive properties exceed that of zinc tetraoxychromate. Invention provides applying low toxic anticorrosive pigment-inhibitors with protective properties comparable with that of chromate pigments. ^ EFFECT: expanded assortment of anticorrosive pigments. ^ 1 tbl |
