Abstract

The invention provides the preparation method of a nylon copper steel composite wire which comprises the steps of: step 1, degreasing, acid cleaning of steel wires, smearing the waterproof gel on the steel wire surface to acquire the steel wire attached with waterproof gel; step 2, drying the nylon powder and the powders of copper or copper alloy respectively to acquire the dried nylon powders and dried copper and copper alloy powders; step 3, extracting out the dried nylon powder, additives, reinforcing agent and dried copper or copper alloy powder; step 4, injecting the mixture into the extruder, extruding out averagely the mixture and the steel wires with waterproof gel to obtain the nylon copper steel composite wire. The nylon copper steel composite wire provided by the invention is characterized by the simple preparation, simply processing, low production costs which enables it to be industrialized. The nylon copper steel composite wire not only has a simple structure, but also enjoys wonderful mechanical properties, anti-corrosion and anti-biological adhesion features and is highly recommended to be applied in the manufacturing of net cage for marine culture.

Description

technical field [0001] The invention specifically relates to a nylon copper-steel composite wire and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Traditional cage nets are generally made of synthetic fiber fishing net materials (including polyethylene fishing nets or polyamide fishing net materials), and nets made of synthetic fiber fishing nets will be covered with marine periphytons after being placed in the sea for a period of time , They will not only affect the water exchange inside and outside the cage, but also affect the growth of farmed fish, causing the farmed fish to get sick. In addition, during the use of penning nets, they have to resist strong storms. There are often high-level storms at sea, which will have a strong impact on the fishing nets in a short period of time. If the seawater cages are made of poor materials, the hurricane will destroy the seawater nets In addition, the strength o...
