Problems solved by technology

[0002] Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials. Among them, polyethylene fishing nets are made of polyethylene materials through melt plasticization, spinning, and ply twisting. They are used for marine trawls, purse seines, and wind-resistant sea nets. Boxes, etc., have a longer service life and higher fishing efficiency, but the mechanical properties of polyethylene itself are average, the tensile strength is low, and the creep resistance is not good, which leads to the strength and wear resistance of traditional polyethylene fishing nets. Performance and toughness are not suitable for fishing operations in complex seabed and high wind and waves environment, which reduces the service life of fishing gear, not only wastes resources, but also directly affects the catch

Embodiment 1

[0014] A fishing net that can reduce marine biological pollution is characterized in that it is made up of the following raw materials in parts by weight (kg):

[0015] Ultra-high molecular weight polyethylene 100, polyethylene terephthalate 2, jojoba oil 2, methylisothiazolinone 1, triallyl cyanurate 0.4, modified plasticizer 5;

[0016] The modified plasticizer is composed of the following raw materials in parts by weight: 1.2 methyltriethoxysilane, 2.3 dioctyl ester, 1.4 tributyl citrate, 2.3 peanut oil, 1.2 turpentine oil, 0.4 eucalyptus oil, Polyisodiene 1.4, morpholine 0.3, antioxidant MB 1.2, methyl ethyl ketone peroxide 0.3, styrene 1.4, nano titanium dioxide 0.3;

[0017] Add the above methyl ethyl ketone peroxide dropwise to other material mixtures, stir for 70 minutes, raise the temperature to 130°C, and stir for 2-3 hours to obtain the modified plasticizer.

[0018] A method for preparing a fishing net capable of reducing marine biological pollution, comprising th...

Abstract

The invention discloses a fishing net for reducing marine biological pollution. The fishing net comprises the following raw materials in parts by weight: 94-100 parts of ultra-high molecular weight polyethylene (UHMWPE), 2-4 parts of polyethylene terephthalate (PET), 1-2 parts of jojoba oil, 1-2 parts of methylisothiazolinone, 0.3-0.4 part of triallyl cyanurate, and 3-5 parts of a modified plasticizer; the fishing net provided by the invention can greatly reduce pollution to the fishing net caused by marine organism, and growth of bacteria and corrosion, and is simple and convenient to clean.

Description

technical field [0001] The invention mainly relates to a fishing net, in particular to a fishing net capable of reducing marine biological pollution. Background technique [0002] Modern fishing nets are mainly processed with polyethylene, nylon and other raw materials.
