Fishing net wire traction coolant

Abstract

The invention discloses a fishing net wire traction coolant which is prepared from the following raw materials in parts by weight: 5-6 parts of rosin amine, 10-12 parts of silicone emulsion, 20-30 parts of waste engine oil, 3-4 parts of clove oil, 4-5 parts of aqueous acrylic ester and 1-2 parts of NaCl. The waste engine oil can be reused in the fishing net wire traction coolant disclosed by the invention; as the fishing net wire traction coolant is prepared from an organic solvent and multiple additives, variation of crystallinity and uniformity of a fishing net wire can be effectively prevented; meanwhile, drawn in the coolant, the fishing net wire can be prevented from being directly exposed in air after being molded, and surface oxidation of the fishing net wire can be prevented; moreover, as the fishing net wire has certain pressure in the coolant, the drawing uniformity of the fishing net wire is improved.

Description

technical field [0001] The invention belongs to the field of textile treatment liquids, and in particular relates to a cooling liquid for pulling fishing nets. Background technique [0002] Now fishing nets are mostly processed with nylon. Nylon 6 has a low melting point and a wide range of process temperatures. It is more impact and solvent resistant than nylon 66 plastic, but is also more hygroscopic. Mold temperature: 60-100°C. The mold temperature significantly affects the crystallinity, and the crystallinity affects the mechanical properties of the plastic parts. For structural parts, the crystallinity is very important, so the mold temperature is recommended to be 80-90°C. For thin-walled plastic parts with a long process, it is also recommended to use a higher mold temperature. Increasing the mold temperature can increase the strength and rigidity of the plastic part, but it reduces the toughness. When processing the fishing net line, the crystallinity of nylon 6 ...

AI Technical Summary

Problems solved by technology

When processing the fishing net line, the crystallinity of nylon 6 should be reduced to improve the toughness of the fishing net line. After the fishing net line is extruded, it often needs to be stretched to prevent the shrinkage of the fishing net line and cause the fishing net line to drop evenly. During the stretching process, it often needs to be stretched. Causes changes in the crystallinity of the fishing net line, affecting the performance of the fishing net line
