Novel anti-corrosion coating and preparation method thereof

The invention discloses a novel anti-corrosion coating and a preparation method thereof and solves the problem of reduction of mechanical performances of the coating since a corrosion inhibitor on a fly ash anti-corrosion coating in the prior art is difficult to disperse. In the invention, through a reflux method, phenyl phosphonic acid and a surfactant are grafted on surface of fly ash, wherein the phenyl phosphonic acid and the surfactant are hydrolyzed during a heating process and are connected to a part of hydroxyl groups on the surface of the fly ash. The grafted fly ash finally turns into sea urchin-like granules. The phenyl phosphonic acid increases dispersion of fly ash particles in resin and combination area of the fly ash particles with resin, thereby greatly improving anti-wear performance of coating. The phenyl phosphonic acid and the surfactant can enable the corrosion inhibitor to be dispersed in nano-micro pores in the fly ash more uniformly, thereby achieving the corrosion inhibition effect and improving the anti-corrosion performance of the coating.
