Samarium-doped zinc oxide solid solution anticorrosive paint for earth-covered storage tank and preparation method thereof

The invention provides samarium-doped zinc oxide solid solution anticorrosive paint for an earth-covered storage tank and a preparation method of the samarium-doped zinc oxide solid solution anticorrosive paint, and relates to the technical field of high polymer materials. The preparation method comprises the following steps: S1, in a nitrogen atmosphere, adding a transition metal ditelluride into a 11-bromo-1-undecanol solution, and reacting at a certain temperature to obtain a ditellurium bond monomer; s2, slowly adding a diisocyanate solution into dihydric alcohol, carrying out heating reaction for a period of time, then dropwise adding a tellurium bond monomer, and continuing the reaction to obtain a polyurethane system; and S3, adding epoxy resin and the samarium-doped zinc oxide solid solution into the polyurethane system obtained in the step S2, and carrying out a reaction at a certain temperature to obtain the samarium-doped zinc oxide solid solution anticorrosive paint for the soil-covered storage ta
