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 polyoxymethylene monofilament for fishing, which is made of the following components in parts by weight: 75-90 parts of polyoxymethylene, 0.5-3 parts of graphene, 7.5-17 parts of thermoplastic polyurethane, and 0.5 parts of antioxidant 3 parts, 0.5-1 part of formaldehyde absorbent, 0.5-1 part of formic acid absorbent, 0.5-1 part of lubricant. The polyoxymethylene monofilament for fishery provided by the present invention uses graphene and thermoplastic polyurethane to blend and then strengthens and toughens the polyoxymethylene. Polyoxymethylene monofilament has the advantages of simple operation process and low production cost. The reinforced and toughened polyoxymethylene monofilament for fishery prepared by the invention can be used in polyoxymethylene rope nets, ocean-going trawls, breeding nets, polyoxymethylene 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...
