The invention provides a steel wire rope core for elevators and a making method thereof. The steel wire rope core is mainly prepared from the following raw materials, by weight, 30-35 parts of polyester fibers, 15-20 parts of polyethylene fibers, 12-15 parts of aramid fibers, 8-10 parts of graphene, 8-10 parts of metal sulfide, 2-5 parts of silicon carbide, and 5-25 parts of filler. The performances of the steel wire rope core for elevators are better than those of imported rope cores. The steel wire rope core for elevators has high strength, high modulus, high density and good oil absorption performance, has the advantages of high diameter uniformity, high bending fatigue resistance, high abrasion resistance, high resistance to chemical corrosion and the like, and is a novel energy-saving and environment-friendly high-tech material. By adopting a steel rope made of the steel wire rope core, smooth operation of elevators is realized, and the fatigue life of the steel rope can be prolonged.
