[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 poly

Embodiment 1

[0014] A nylon reinforced fishing net 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, nylon PA66 4, N-2-(aminoethyl)-3-aminopropyltrimethoxysilane 0.2, dodecyldimethyl tertiary amine 0.2, modified plasticizer 2;

[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 90 minutes, raise the temperature to 130° C., and stir for 3 hours to obtain the modified plasticizer.

[0018] A preparation method of nylon reinforced fishing net, comprising the following steps:

[0019] Take 20% of the weigh...

Abstract

The invention discloses a nylon-reinforced fishing net which comprises the following raw materials in parts by weight: 90-100 parts of ultra-high molecular weight polyethylene, 3-4 parts of nylon PA66, 0.1-0.2 part of N-2-(aminoethyl)-3-aminopropyltrimethoxysilane, 0.1-0.2 part of N,N-dimethyldodecylamine and 1-2 parts of a modified plasticizer. The fishing net produced by the invention is high in tensile strength, strong in toughness and weather resistance, and high in elongation at break in filaments, and added nylon enhances all physical properties of a finished product and improves the toughness.

Description

technical field [0001] The invention mainly relates to a fishing net, in particular to a nylon reinforced fishing net. Background technique [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. The performance and toughness are not suitable for fishing operations in complex seabed and strong wind and waves environment, which reduces the service life of fishing gear, not only wastes resources, but also directly affects the catch. ...
