Preparation and Characterization of Inorganic Zinc-Rich Coatings Based on Geopolymers
In this work,a high performance,environmentally friendly and waterborne inorganic zinc-rich coating based on geopolymer was developed and applied as protective coating of steel substrate.The geopolymer was the main ingredient of the zinc-rich paint (ZRP),and the zinc powder and additives were added to geopolymer to prepare ZRP.The corrosion protection behaviors of ZRP with different kinds of zinc powder and various zinc contents were characterized by electrochemical protection performance test.The results showed that coatings with 55 wt% spherical zinc powder and 25 wt% lamellar zinc powder exhibited good corrosion resistance mainly because of the cathodic protection and barrier effect.
