Problems solved by technology

This product can form a protective film on the outside of the steel wire rope to resist the corrosion of external moisture, reduce wear, and is more convenient to apply. However, due to poor fluidity, this product can only partially penetrate and usually cannot fill the steel wire rope core, which will eventually lead to internal corrosion of the steel wire rope. Corrosion and wear greatly reduce the service life of the wire rope

Abstract

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.

Description

technical field [0001] The invention relates to an elevator wire rope lubricating grease and a preparation method thereof. Background technique [0002] In order to prevent the wear and tear caused by the mutual movement inside the wire rope and prevent the wire rope from rusting, it is necessary to add grease to the elevator wire rope during operation. Lubricates the wire rope. During the use of the steel wire rope, during the ever-changing pulling, slack, rolling, and traction process, there is often movement and friction between the steel wires, between the rope and the wheel, and between the rope and the rope. coefficient, so that the steel wire rope is evenly stressed, and the lubrication performance of the fatigue bending performance of the steel wire is improved, so that the grease can be anti-corrosion and lubricated, and the hemp core can be protected at the same time. [0003] It is a penetrating volatile lubricant, which contains a large amount of diluting solve...
