Environment-friendly coating material and preparation method thereof

The invention discloses an environment-friendly coating material and a preparation method thereof, the environment-friendly coating material comprises a phase A and a phase B. The phase A comprises a polymer containing more than two epoxy groups, a glycidyl ether compound and colored sand; and the phase B comprises a curing agent. The specific fumed silica and the silicon powder are added to serve as filler together, the flowability of a system is improved, the dispersion effect of the silicon powder in the system is remarkably improved, meanwhile, the fumed silica is added to generate a synergistic effect with the epoxy resin sand containing the modified graphene oxide and the resin color sand, and the dispersion effect of the silica powder in the system is improved. The prepared coating material has better impact resistance and wear resistance; the environment-friendly coating is high in operability, paint preparation and construction are convenient and safe, meanwhile, the material has high crosslinking de
