Preparation method of black iron oxide particles with corrosion inhibition performance

The invention discloses a preparation method of black iron oxide particles with corrosion inhibition performance. The method comprises the following steps of: dissolving urotropin, ethyl hydroxy ethylcellulose and lauryl sodium sulfate in deionized water according to the definite weight ratio, thereby obtaining a viscous liquid; putting black iron oxide into a granulating machine for granulating while evenly spraying the viscous liquid onto the black iron oxide powder at the same time, thereby forming small black iron oxide particles; and drying and screening the small black iron oxide particles, thereby obtaining a finished product. According to the method, the black iron oxide is modified by the urotropin and other components, so that the corrosion inhibition performance of the black iron oxide is enhanced; and the liquidity and the dispersibility of a black iron oxide pigment are realized. The produced black iron oxide has the characteristics of being excellent in temperature resistance, good in acid and alkali resistance, strong in light absorption, high in tinting strength, good in compatibility and dispersibility and the like, thereby being wide in market prospect.
