The invention relates to the technical field of steel ladle slag resistance of refractory materials, in particular to an environment-friendly regenerated magnesia carbon brick and a preparation methodthereof. According to the technical scheme, 18.0-33.0 wt% of 5-3 mm magnesia carbon brick regenerated particles, 22.0-37.0 wt% of 3-1 mm magnesia carbon brick regenerated particles, 15.0-30.0 wt% of1-0 mm magnesia carbon brick regenerated particles and 17.0-32.0 wt% of magnesia carbon brick regenerated micro powder with the particle size smaller than or equal to 0.074 mm are adopted as raw materials, and 2.6-3.8 wt% of liquid thermosetting phenolic resin binder, 0.5-3.5 wt% of boron carbide and 0.2-3.8 wt% flake graphite are added. The method comprises steps: uniformly mixing, homogenizing,carrying out compression molding, heating to 150-300 DEG C, and carrying out heat treatment for 24 hours to obtain the regenerated magnesia carbon brick. The novel preparation method of the regenerated magnesia carbon brick has the advantages that the regenerated magnesia carbon brick prepared by the preparation method is high in slag resistance, good in thermal shock resistance, low in molten steel pollution and positive in steelmaking, and the energy utilization rate can be increased.
