Elevator steel wire rope lubricating grease and preparation method thereof

The invention relates to elevator steel wire rope lubricating grease and a preparation method thereof. The lubricating grease comprises the following components in parts by weight: 25-30 parts of microcrystalline wax, 2-3 parts of polyethylene wax, 58-65 parts of base oil, 2-3 parts of pour point depressant, namely poly-alpha olefin, 0.1-0.5 parts of antioxygen, namely butylated hydroxytoluene, 2-3 parts of antirust agent, namely barium sulfonate, 2-3 parts of tackifier, namely polyisobutylene, and 0.1-0.5 parts of fretting wear resistant agent, namely sulfur-phosphorous type ashless antiwear agent. The lubricating grease has the advantages that a using temperature range is wider; the carrying capacity is higher; and the oxidation stability, the rust resistance, the fretting wear resistance and the like are good.
