Abstract

The invention relates to the technical field of polyamide fishing lines, and discloses a low-elongation polyamide fishing line and a preparation method thereof.The low-elongation polyamide fishing line comprises a polycaprolactam oligomer and a thermoplastic elastomer, and the polycaprolactam oligomer is prepared from, by weight, 1-1.4 parts of caprolactam, 0.5-0.8 part of 6-aminocaproic acid, 6-0.9 part of adipic acid and 10-15 parts of water; the reinforcing body is prepared from the following raw materials in parts by weight: 0, 3 to 0.7 part of polyethylene glycol, 0.7 to 0.99 part of tetrabutyl titanate, 0.2 to 0.6 part of pentaerythritol, 0.4 to 0.8 part of m-phenyl bisoxazoline, 0.1 to 0, 3 parts of an antioxidant 168 and 0.2 to 0.4 part of an antioxidant 1010. According to the fishing line, the polyethylene glycol, the tetrabutyl titanate, the pentaerythritol, the m-phenyl bisoxazoline, the antioxidant 168 and the antioxidant 1010 are added into the polycaprolactam oligomer, so that the strength of the polyamide is improved, the toughness of the polyamide is reduced, and the situations that the fishing line is pulled, the fishing line is extended and the strength of the fishing line is reduced in the using process of the fishing line are avoided.

Description

technical field [0001] The invention relates to the technical field of polyamide fishing lines, in particular to a low elongation polyamide fishing line and a preparation method thereof. Background technique [0002] Polyamide is commonly known as nylon (Nylon), the English name is Polyamide, which is a general term for polymers containing amide groups in the repeating units of the macromolecular main chain. Polyamides can be obtained by ring-opening polymerization of lactic acid amines, or by polycondensation of diamines and dibasic acids. Polyamide (PA) refers to a high polymer whose main chain unit contains polar amide groups (-CO-NH-). [0003] At present, when the polyamide existing on the market is used as a fishing line, because the polyamide has a certain good toughness, when the polyamide fishing line is pulled, the fishing line will extend to a certain extent. The cross-sectional area becomes smaller, resulting in lower strength of the fishing line. [0004] To ...
