Problems solved by technology

At present, in order to improve the strength of fishing nets, people use a large amount of fillers and other ingredients. Although the strength has increased, the elongation at break has decreased greatly, which is also not conducive to the normal use of fishing nets, so there has been a trade-off Bad problems, so it is necessary to ensure that the overall performance is good, and then properly enhance its characteristics in certain aspects

Abstract

The invention discloses a processing technology of a high-strength high-tenacity fishing twine. The processing technology comprises the following steps: firstly, drying and crushing polypropylene and polyethylene; mixing crushed polypropylene and polyethylene with rubber, glyceryl monostearate, microcrystalline wax, dihydro-quinoline, bisoctadecyl ester and modified nano-zinc oxide; performing granulation; placing the granules in an injection molding machine to be subjected to injection molding; and cooling, drawing and stretching a semi-finished product obtained through molding. Various raw material ingredients are reasonably selected, and meanwhile, the specific processing technology is improved, so that the use features of the end-product fishing twine are effectively improved, the fishing twine is uniform in thickness and stable in overall quality, the breaking strength can be improved by 14-20%, the knot strength can be improved by 10-15%, decrease of the elongation at break is controlled to be within 4% on the basis of strength improvement, besides, the processing yield can reach 99.9% or above, the overall characteristic is excellent and the popularization value is high.

Description

technical field [0001] The invention belongs to the technical field of fishing gear processing, and in particular relates to a processing technology for a high-strength and high-toughness fishing net line. Background technique [0002] Fishing nets, as the name implies, are nets for fishing. Ancient people used coarse cloth and hemp as raw materials to make fishing nets by bundling. Although this kind of fishing net is perishable and has poor toughness, its fishing efficiency has been greatly improved. At present, more than 99% of the structural materials of special fishing tools are processed with synthetic fibers, mainly including nylon, polyethylene, polyester, polyvinylidene chloride and other fibers. With the development of fishery, the objects of fishing and hunting are not only fish, but also the fishing tools are advancing with the times. Fishing nets require high transparency and strength, good impact resistance, abrasion resistance, mesh dimensional stability and ...
