Steel strand with polyurea protection material on outer layer and manufacturing method of steel strand
The invention discloses a steel strand with a polyurea protection material on the outer layer. A steel strand body with the polyurea protection material on the outer layer is formed in the manner that a polyurea protection coating I made of the polyurea material is arranged on the periphery of the whole steel strand, or the gap formed through twisting of a center wire and side wires is filled with the polyurea material, and a steel strand body with the polyurea protection material on the outer layer is formed in the manner that the polyurea protection coating I made of the polyurea material is arranged on the periphery of the whole steel strand. A manufacturing method of the steel strand comprises the steps that in steel wire preprocessing, surface processing and priming are carried out, the preprocessed center wire and the preprocessed side wires are twisted to form the steel strand, one or more of the polyurea material coating procedure I, the twining and wrapping procedure, the polyurea material coating procedure II, the polyurea material coating procedure III, the extrusion molding procedure and other procedures are carried out, and the series steel strand with multiple protection is manufactured. The manufacturing method is easy and convenient to conduct. The manufactured steel strand is high in tensile strength, good in flexibility, high in damping, resistant to ageing and abrasion, and good in vibration damping performance; and the anti-corrosion capability of the steel strand can be greatly improved, and the service life of the steel strand is prolonged.
