The invention relates to a solid wood door which comprises a wood door body. The wood door body is formed by combination of an outer door sheet, a door core and an inner door sheet. The outer door sheet and the inner door sheet are solid wood boards covered with fire-retardant coating and activated carbon, and the fire-retardant coating is composed of a base material (namely a film forming material), pigments, a normal coating additive, a fire-retardant additive, a dispersion medium and the like. The fire-retardant additive is composed of tellurium dioxide, ammonium sulfate, magnesium hydroxide, ammonium dihydrogen phosphate, diammonium phosphate, sodium dodecyl sulfate and the rest of carbamide. The coating of the solid wood door has the advantages of nontoxicity, corrosiveness avoidance, excellent fireproof effects, low cost and convenience in use, and the activated carbon covering the coating is capable of adsorbing indoor poisonous gas to purify indoor air.
