The invention relates to the field of protective doors, in particular to a multifunctional fireproof door. The multifunctional fireproof door comprises a door frame and a door sheet, wherein the door sheet is hinged to the door frame; sealing strips are respectively arranged at edges of the door sheet and edges of an inner frame of the door frame; the door sheet sequentially comprises a refractory slab, a sand filling layer, a thermal-insulation layer and a sound-insulation layer from outside to inside; the refractory slab becomes an external frame body of the door sheet; a cavity which is reserved between the refractory slab and the thermal-insulation layer becomes the sand filling layer; the sand filling layer is filled with refractory sand; and the refractory sand in the sand filling layer comprises black silicon carbide and green silicon carbide. By adoption of the fireproof door, open fire can be isolated effectively, fireproof and thermal-insulation effects are excellent, and a noise reduction effect is also good. The multifunctional fireproof door is quite suitable to be used in large manufacturing shops with high fire protection requirements.
