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] An anti-aging 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, EVA resin 4, N-cyclohexyl-N'-phenyl-p-phenylenediamine 0.2, tetrachloroisophthalonitrile 1, cis-1,4-polyisoprene rubber 4, 2-mercaptobenzimidazole 0.4, modified plasticizer 3;

[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 for an anti-aging fishing net, comprising the foll...

Abstract

The invention discloses an anti-aging fishing net. The anti-aging fishing net comprises the following raw materials in parts by weight: 97-100 parts of UHMWPE, 3-4 parts of EVA resin, 0.1-0.2 part of N-cyclohexyl-N'-phenyl p-phenylenediamine, 1-2 parts of tetrachloroisophthalonitrile, 3-4 parts of cis-1, 4-polyisoprene rubber, 0.2-0.4 part of 2-mercapto benzimidazole, and 3-4 parts of a modified plasticizer; according to the anti-aging fishing net provided by the invention, the N-cyclohexyl-N'-phenyl p-phenylenediamine and the 2-mercapto benzimidazole are adopted so as to improve the anti-aging function and the thermostability of the fishing net.
