Problems solved by technology

Due to technical problems, my country's domestic high-density polyethylene can't meet the needs of fisheries, and most of them rely on imports, which cost a lot of foreign exchange costs. However, imported and domestic high-density polyethylene generally show mediocre mechanical properties, especially It is the breeding net, fixed net, etc. that have been exposed to the atmosphere for a long time, and the mechanical properties are more likely to be reduced, resulting in a significant reduction in the life of the fishing net.

Abstract

The invention discloses a polyethylene fishing net thread with good mechanical property, and relates to the technical field of new materials. The polyethylene fishing net thread with good mechanical property contains 1-hydroxybenzotriazole modified polyethylene accounting for 78-85% of the mass of the polyethylene fishing net thread; the polyethylene fishing net thread prepared according to the invention has good breaking strength and knot strength. According to the invention, 1-hydroxybenzotriazole modified polyethylene is adopted, so that the comprehensive mechanical performance of polyethylene is greatly improved, and then the use performance of the fishing net is effectively improved; 1-hydroxybenzotriazole modified polyethylene adopted according to the invention is more significant inthe effect of improving the mechanical performance of polyethylene in comparison with modified polyethylene recorded in the prior art.

Description

Technical field [0001] The invention belongs to the technical field of new materials, and specifically relates to a polyethylene fishing net line with good mechanical properties. Background technique [0002] High-density polyethylene as a fishing net material has been widely used in my country. In the past ten years, the annual consumption of the country has accounted for more than 80% of the fishing net material. Except for purse nets and drift nets, almost all use high-density polyethylene as the main net material. It is a fishing net material widely used in my country. Due to technical problems, my country's domestically produced high-density polyethylene cannot meet the needs of fisheries, and most of it relies on imports, which consumes a lot of foreign exchange costs. However, imported and domestically-produced high-density polyethylene also generally show general mechanical properties, especially It is a breeding net, fixed net, etc. that are exposed to the atmosphere for ...
