Copper steel composite material for seawater enclosing aquaculture fishing net and manufacturing method for copper steel composite material

Abstract

The invention provides a copper steel composite material for a seawater enclosing aquaculture fishing net. The outer layer of the copper steel composite material is a copper alloy layer; the core part of the copper steel composite material is steel; a cementing layer is arranged between the core part and the copper alloy layer; the thickness of the copper alloy layer is 1 to 3mm; the mass percent of the copper in the copper alloy layer is at least 70 percent or above; the strength of the steel is greater than 600 MPa; the material of the cementing layer is epoxy resin or phenolic resin; the thickness of the cementing layer is 10 to 30 micron. The invention also provides a manufacturing method for the copper steel composite material for the seawater enclosing aquaculture fishing net. According to the copper steel composite material for the seawater enclosing aquaculture fishing net and the manufacturing method for the copper steel composite material, the copper and the steel are compounded, and the copper alloy coats the surface layer of the steel, so that the advantages of the corrosion resistance and the biofouling preventing property of the copper alloy can be fully played; the core part is made of the steel with high strength, so that the advantages of high mechanical properties of the steel are fully played; the steel and the copper are combined, so that the requirements on the fishing net materials of sea farming can be met better; the steel is coated with the copper, so that the steel is not exposed in seawater, and the problem of corrosion is avoided.

Description

technical field [0001] The invention belongs to the field of metallurgy and relates to an alloy, in particular to a copper-steel composite material for seawater enclosure fishing nets and a manufacturing method thereof. Background technique [0002] The nets of the existing cages are generally made of synthetic fiber fishing net materials (including polyethylene fishing nets or polyamide fishing net materials), and the nets equipped with synthetic fiber fishing nets will be covered with marine periphytons after a period of time in the sea area of ​​my country. , They not only affect the exchange of water inside and outside the cage, affect the daily operation and maintenance of farmers, but also affect the growth of farmed fish and cause the disease of farmed fish. [0003] Due to the problems of synthetic fiber fishing net materials, brass alloy net cages have been tried in Shengsi Sea Area, Zhejiang Province, my country. The advantages of copper alloy mesh cages are as fol...
