Abstract

The invention discloses a polyoxymethylene monofilament, which is made of the following components in parts by weight: 100 parts of polyoxymethylene, 5-25 parts of polyethylene octene copolymerized elastomer, 0.5-10 parts of nano silicon dioxide, anti-oxidation 0.1-1 part of anti-oxidant, 0.1-1 part of antioxidant, 0.1-0.5 part of lubricant. The invention also discloses a polyoxymethylene wear-resistant rope for ecological fences prepared from the polyoxymethylene monofilament. The obtained rope has the advantages of good safety, low price, excellent wear resistance and high breaking strength, and has a certain Antibacterial antifouling effect.

Description

technical field [0001] The invention belongs to the technical field of fishing materials, and in particular relates to a polyoxymethylene monofilament for fishing and a preparation method thereof, and a polyoxymethylene wear-resistant rope for an ecological fence. Background technique [0002] The ecological fence breeding mode is an effective way to adjust the structure to adapt to the transformation of aquaculture in my country after the cage culture, and to improve the quality and efficiency of the aquaculture industry. In the field of fishery, a product made of twisted strands with a diameter greater than 4mm is called a rope, and the rope is one of the essential materials for ecological fence farming. At present, fishery synthetic fibers are constantly receiving national and international marine fishery research attention. Fishery synthetic fibers provide a good choice for the selection or research and development of ecological fence culture, culture cages, fishing gear...
