Using high-temperature mechanochemistry treatment to modify iron oxide and improve the corrosion performance of epoxy coating - I. High-temperature ball milling treatment

This study achieved the surface modification of iron oxide pigment by using epoxy resin with high-temperature ball milling device. The compatibility of the modified iron oxide with the epoxy resin and the corrosion protection of epoxy coatings containing the modified iron oxide were investigated. The results show that the epoxy resin molecules grafted on the surface of the iron oxide, and the improved compatibility of the modified iron oxide with the epoxy resin lessens the interface defects between the iron oxide particles and the epoxy resin and enhances the corrosion resistance of the coating.
