Steel strand inhaul cable filled or coated with polyurea protective material and manufacturing method of steel strand inhaul cable
The invention relates to a steel strand inhaul cable filled or coated with a polyurea protective material. The steel strand inhaul cable comprises series steel strand inhaul cable bodies including the steel strand inhaul cable body Ia formed in a manner that gaps between n steel strands are filled with the polyurea protective material, the steel strand inhaul cable body Ib formed in a manner that the outer layer of the steel strand inhaul cable body Ia is coated with a polyurea protective coating and the like. A manufacturing method includes the steps that the n steel strands are pretreated, dried and filled with the polyurea protective material, a steel strand combination is molded through coalescence, and the steel strand inhaul cable body Ia filled or coated with the polyurea protective material is formed; and the series steel strand inhaul cable which has multiple protective functions is manufactured by the steel strand inhaul cable body Ia through one or more of the polyurea material coating process I, the wrapping and packaging process, the polyurea material coating process II and III, the extrusion molding process and the like. The method is simple and convenient; the manufactured steel strand inhaul cable is good in tension-resisting strength and flexibility, high in damping and good in ageing resistance, wear resistance and damping performance; the corrosion prevention capacity of the steel strand inhaul cable can be greatly improved, and the service life of the steel strand inhaul cable can be prolonged; and the n is larger than or equal to 1.
