Abstract

The invention discloses a high-performance steel wire rope with a sisal hemp core. The high-performance steel wire rope with the sisal hemp core comprises a steel wire layer and the sisal hemp core,wherein a zinc layer is arranged on the outer wall of the steel wire layer; a composite layer is arranged on the side wall of the sisal hemp core in a twisting manner; the steel wire layer is arrangedon the outer wall of the composite layer in a twisting manner; and the sisal hemp core is formed by stranding three sisal hemp ropes. The formula of the composite layer comprises the following components by mass: 20-30 parts of phenolic resin, 20-30 parts of acrylic resin, 60-90 parts of poly (p-phenylene terephthalamide), 5-10 parts of graphite, 20-30 parts of nitrile rubber, 5-10 parts of metalsulfide and 10-15 parts of silicon carbide. The service life of the steel wire rope and the service life of the sisal hemp core can be prolonged, the sisal hemp core is protected, the corrosion resistance of the sisal hemp core is improved, and the strength of the steel wire rope is improved.

Description

technical field [0001] The invention relates to the technical field of steel wire ropes, in particular to a high-performance sisal-core steel wire rope. Background technique [0002] The steel wire rope is a spiral steel wire bundle twisted together with steel wires whose mechanical properties and geometric dimensions meet the requirements according to certain rules. The steel wire rope is composed of steel wire, rope core and lubricating grease. The steel wire rope is first twisted into strands by multi-layer steel wires, and then twisted into a helical rope by a certain number of strands with the rope core as the center. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light weight, stable operation, and is not easy to break suddenly, and the operation is reliable. The main function of the rope core is to support the steel wire rope to achieve a stable cross-sectional structure. Rope cores i...
