Problems solved by technology

In order to prepare high-performance polyoxymethylene fibers and make them have sufficient tensile breaking strength, they must be subjected to high-speed thermal drawing in the production process, and high-modulus and high-strength polyoxymethylene fiber samples can be obtained, but polyoxymethylene fibers After super-stretching, it will show greater brittleness, and has the disadvantages of notch sensitivity and low impact strength.

Abstract

The invention discloses a polyformaldehyde monofilament for fishing. The polyformaldehyde monofilament is prepared from the following components in parts by weight: 75-90 parts of polyformaldehyde, 0.5-3 parts of graphene, 7.5-17 parts of thermoplastic polyurethane, 0.5-3 parts of an antioxidant, 0.5-1 part of a formaldehyde absorbent and 0. 5-1 part of a lubricant. According to the fishing polyformaldehyde monofilament, graphene and thermoplastic polyurethane are blended, then polyformaldehyde is reinforced, toughened and modified, and the polyformaldehyde monofilament for fishing is preparedby melt spinning, three-stage thermal stretching and heat setting processes. A preparation method has the advantages of simple operation process and low production cost. The prepared reinforced and toughened polyformaldehyde monofilament for fishing can be used for polyformaldehyde rope nets, ocean trawls, breeding nets, polyformaldehyde ropes and the like.

Description

technical field [0001] The invention belongs to the technical field of fishery materials, and in particular relates to a polyoxymethylene monofilament for fishery and its preparation method and application. Background technique [0002] In the early days, the development of fishery benefited from the use of natural fibers, but there are many deficiencies in natural fibers. The strength cannot meet the use of some nets, and the wear resistance and weather resistance cannot meet the use of some environments. With the development of science and technology and the emergence of synthetic fibers, it makes up for the shortage of natural fibers and meets the needs of large-scale, modern and special deep-water operations in modern fishery production. Fiber, new fishery synthetic fiber materials such as polyarylate fiber, biodegradable fiber, ultra-high molecular weight polyethylene fiber and high-strength fishery polyethylene monofilament have appeared. As the country continues to d...
