Problems solved by technology

[0002] Traditional marine enclosure fishing nets are generally woven with nylon materials. Nylon cages have poor biofouling resistance. After being used in sea areas for a period of time, fishnet cages will be covered with marine fouling organisms, the most important of which are algae and hydra. , external anal animals, snails, bivalves, barnacles and sea squirts, etc.
The attachment of a large number of organisms not only affects the smooth flow of water in the fishing net box, reduces the activity space of the cultured products, but also affects the nutrition and taste of the cultured products, and seriously causes the disease of the farmed fish. Manual operation and maintenance is time-consuming and labor-intensive

Abstract

The invention provides a preparation method for a nylon and copper alloy composite material. The preparation method is characterized by comprising the following steps: 1, drying nylon powder and copper alloy powder in a drying oven to obtain dried nylon powder and dried copper alloy powder; 2, mixing the dried copper alloy powder, the dried nylon powder and a coupling agent in a high-speed mixer to obtain a mixed material, and taking the mixed material out; 3, adding the mixed material into a double-screw extruder, and performing uniform mixing and extrusion to obtain the nylon and copper alloy composite material. The preparation method for the nylon and copper alloy composite material is simple, easy to operate, low in preparation cost and suitable for industrial application. The nylon and copper alloy composite material prepared by the preparation method for the nylon and copper alloy composite material has high microorganism adhesion resistance of copper, high seawater corrosion, strong tensile strength and long service life.

Description

technical field [0001] The invention specifically relates to a nylon-copper alloy composite material and a preparation method thereof. Background technique [0002] Traditional marine enclosure fishing nets are generally woven with nylon materials. Nylon cages have poor biofouling resistance. After being used in sea areas for a period of time, fishnet cages will be covered with marine fouling organisms, the most important of which are algae and hydra. , external anal animals, dragon cyprids, bivalves, barnacles and sea squirts, etc. The attachment of a large number of organisms not only affects the smooth flow of water in the fishing net box, reduces the activity space of the cultured products, but also affects the nutrition and taste of the cultured products, and seriously causes the disease of the farmed fish. Manual operation and maintenance is time-consuming and labor-intensive. Contents of the invention [0003] The present invention is carried out to solve the abov...
