Abstract

The invention discloses a galvanized steel strand for a corrosion-resistant maritime work optical cable and a preparation process of the galvanized steel strand. The steel strand is mainly made of a plurality of hot-dip galvanized steel wires; each hot-dip galvanized steel wire comprises a steel wire body, an aluminum layer, a bonding layer and a zinc layer; secondary drawing is carried out after aluminum plating, mixed powder is sprayed to a preheated secondary drawing steel wire body, and the mixed powder is melted on the surface of the steel wire body, wherein 2-aminobenzothiazole and N, N, N', N'-tetraglycidyl-4, 4'-diaminodiphenylmethane react, hydroxyl reacts with epoxy group to generate crosslinking, and amino in a crosslinking product and hydroxyl on the surface of the aluminum layer are subjected to condensation and addition reaction to form a structure similar to a metal organic framework, so that the mechanical property and wear resistance of the steel wires can be improved; and the prepared steel strand has good corrosion resistance, the three-layer structure is adopted, cross-linking among the structures is tighter, the corrosion resistance is better, and good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of galvanized steel strands, in particular to a galvanized steel strand for corrosion-resistant marine optical cables and a preparation process thereof. Background technique [0002] The steel strand is made of multiple steel wires twisted together. It also plays a significant role in the optical cable. It can increase the toughness of the optical cable and can also be used for traction. The most important point of the steel strand is corrosion resistance. , which can greatly improve the service life of the steel strand, can improve the safety performance of the steel strand, and has a great impact on the use of the steel strand in various fields. [0003] In the existing technology, steel wires are usually drawn first, then galvanized, and then twisted into steel strands. This method will cause a large amount of wear of the zinc layer, and a large amount of zinc loss will reduce the corrosion resistance. ...
