The invention provides a floor with industrial residues as main materials. The materials for manufacturing the floor include red mud, functional additives and enhancing carriers. The component includes, by weight, 55 to 70 parts of red mud, 30 to 45 parts of plastic, 0.05 to 4 parts of functional additives A, 3 to 5 parts of functional additives B and 3 to 5 parts of enhancing carriers, wherein the plastic is selected from polyethylene, polrvinyl chloride or polypropylene; the functional additives A are selected from impact modifier chlorinated polyethylene (CPE), plasticizer dioctyl adipate (DOA), and nucleating agent beta crystal form nucleating agent tetramethylbenzidine (TMB)-5; the functional additives B are selected from a processing modifier ethylene propylene diene monomer (EPDM), and an impact modifier methyl methacrylate-butadiem-styrene (MBS) copolymer resin; and the enhancing carriers are E glass fibers. The floor has good corrosion resistance, firmness and light quality, water proofing, fire proofing, electricity proofing properties, sound insulation and heat insulation performances, no radioactive contamination or harmful gas, and good market prospects and use values.
