Problems solved by technology

Fishing nets are required for all kinds of fishing gear, breeding cages, net cages in seawater or freshwater, or fences in lakes and reservoirs. With the development of fisheries, a variety of high-performance fishing nets are gradually popularized and used. Fishing nets The characteristics of high strength, light weight and high cost performance are that the fishing net line has achieved good results in the field of fishery production. However, most fishing nets on the market have low mechanical strength, easy water absorption, high moisture regain, poor toughness, and are not resistant to aging. Wear-resistant, it is easy to be damaged for a long time and affect the use
The tensile strength is low and the creep resistance is not good, so the strength, wear resistance and toughness of traditional fishing nets are not suitable for fishing operations in complex seabed and high wind and waves environment, reducing the service life of fishing gear, not only wasting resources, but also directly affecting fishing catches quantity

Abstract

The invention discloses a polyvinyl fishing net composite material, which is prepared from the following raw materials in parts by weight: 200-300 parts of polyamide slices, 20-30 parts of modified polyethylene fibers, 10-15 parts of dicumyl peroxide, 5-10 parts of antifouling filler, 1-3 parts of compatilizer and 0.5-1 part of anti-aging agent. The invention also discloses a preparation method ofthe polyethylene-based fishing net composite material, which comprises the following steps: uniformly mixing and stirring the raw materials in a reaction kettle, and carrying out extrusion granulation in a double-screw extruder to obtain the polyethylene-based fishing net composite material. By utilizing the special physical and chemical properties of graphene and halloysite, the composite material has the characteristics of favorable mechanical properties, high stain resistance and aging resistance.

Description

technical field [0001] The invention belongs to the technical field of fishing gear preparation, and in particular relates to a polyethylene-based fishing net composite material and a preparation method thereof. Background technique [0002] Fishing net is a net for fishing. The ancient people used coarse cloth and hemp as raw materials, and made fishing nets by binding and rolling. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. Modern Fishing is mainly carried out in the form of trawling, which has the advantages of high production efficiency and convenient operation, but trawling damages the environment in many ways. First of all, it is difficult for tugboats to collect broken fishing nets, causing solid waste pollution. Moreover, once the fish break free from the fishing nets, the fishing nets will become loose and damaged, and the holes of the fishing nets will become larger,...
