Investigation of the anticorrosion efficiency of ferrites Mg1-xZnxFe2O4 with different particle morphology and chemical composition in epoxy-ester resin-based coatings

Popis výsledku v původním jazyce

Mixed metal oxides with the ferrospinet structure ZnFe2O4, Mg0.2Zn0.8Fe2O4 and MgFe2O4 were synthesised by the high-temperature solid-phase process. A series of pigments containing the metals Mg-Zn-Fe was prepared from 4 different starting iron oxides: viz. goethite (FeOOH), hematite (Fe2O3), magnetite (FeO center dot Fe2O3) and specularite (Fe2O3). The properties of the ferrites as pigments were examined in a solvent-based epoxy-ester resin-based coating material at a pigment volume concentration PVCferrite = 10%. The anticorrosion efficiency of the paints with the ferrites was examined by exposing panels coated with the paints to atmospheres with SO2, NaCl, or condensed moisture. Furthermore, the physico-mechanical properties of paint films containing the pigments were evaluated by standardised tests. Ferrites prepared from the needle-shaped FeOOH or lamellar Fe2O3 emerged as pigments with the best anticorrosion properties. From the aspect of chemical composition, the paint films con
