High wear-resistant fishing net suitable for complex seabed fishing environment

Abstract

The invention belongs to the technical field of fishing net processing, and particularly relates to a high wear-resistant fishing net suitable for a complicated seabed fishing environment. The fishing net is prepared by modifying high density polyethylene by modified nanosilicon dioxide with a surface hydroxy number not higher than 0.4 / nm<2>; the use amount of the high density polyethylene is 74 to 78 percent of the total amount of raw materials of the finishing net. Compared with the prior art, the high wear-resistant fishing net has the following advantages: the high density polyethylene is modified by using the modified nanosilicon dioxide, an interval multipore structure is reduced, processability and mechanical properties are obviously improved, the prepared finishing net is high in strength, good in toughness and strong in impact resistance, and has stronger creep resistance and weather fastness in the complicated seabed environment and environment with strong wind and big waves, and the service life is greatly prolonged in the complicated seabed environment, and is more remarkably prolonged in a simple environment.

Description

technical field [0001] The invention belongs to the technical field of fishing net processing, and in particular relates to a highly wear-resistant fishing net suitable for complex seabed fishing environments. Background technique [0002] With the development of fishery, in order to improve the performance of fishing nets, polyethylene and nylon are mainly used as raw materials for processing, which correspondingly increases the service life and strength of fishing nets, but polyethylene itself has general mechanical properties and poor creep resistance. , resulting in the fishing nets are not suitable for complex seabed and fishing operations in strong winds and waves, and are prone to aging, reducing the service life of fishing gear, not only wasting resources, but also directly affecting the amount of fish caught. Therefore, further research and improvement of polyethylene fishing nets is required. Contents of the invention [0003] The purpose of the present invention...

Problems solved by technology

[0002] With the development of fishery, in order to improve the performance of fishing nets, polyethylene and nylon are mainly used as raw materials for processing, which correspondingly increases the service life and strength of fishing nets, but polyethylene itself has general mechanical properties and poor creep resistance. As a result, the fishnets made are not suitable for fishing operations in complex seabed and high wind and waves environment, and are prone to aging, which reduces the service life of fishing gear, not only wastes resources, but also directly affects the amount of fish caught. Therefore, further research and improvement of polyethylene fishing nets is required.
