Zinc-magnesium anticorrosion pigments, anticorrosive paint and process for the preparation of anticorrosive pigments

摘要

The present invention relates to platelet-shaped zinc magnesium pigments, the platelet-shaped zinc magnesium pigments containing 40.8 to 67.8 mol% of zinc, 32.2 to 59.2 mol% of magnesium and 0 to 7 mol% of Mn, Li, Be, Y, Contain Sn, Al, Ti, Fe, Cu and mixtures thereof, each based on the total molar amount of the elements Zn, Mg, Mn, Be, Y, Li, Sn, Al, Ti, Fe and Cu, the mol% Add 100 mol% and the average thickness h50 of the pigments is less than 1 µm. The invention further relates to the use and production of these pigments.
