Method for processing small-specification blending modified polypropylene light-emitting rope for fishing

Abstract

The invention relates to a method for processing a small-specification blending modified polypropylene light-emitting rope for fishing, belonging to the method for processing the light-emitting rope for fishing and needing providing a method for processing the small-specification blending modified polypropylene light-emitting rope for fishing. The small-specification blending modified polypropylene light-emitting rope for fishing is processed by adopting the raw materials of PP resin, HDPE resin, light-emitting powder and assistant. The method is characterized in that a mixture of the PP resin, the light-emitting powder, zinc stearate and white oil is extruded and pelleted to obtain a blending material matrix; a mixture of the blending material matrix, the PP resin and the HDPE resin is melted and extruded by an extruding machine, a raw silk obtained through melting and extruding is cooled and pre-drafted, and a pre-drafted silk is subjected to two times of thermal drafting and then cooled with airflow; the single silk bundle is split into a blending modified polypropylene light-emitting silk for fishing, 36 light-emitting silks are twisted to a Z-direction light-emitting rope yarn, 6 Z-direction light-emitting rope yarns are manufactured into an S-direction rope yarn, and 3 S-direction light-emitting rope yarns are twisted into a small-specification blending modified polypropylene light-emitting rope for fishing in a Z direction. The invention is used for the light-emitting rope for fishing.

Description

technical field [0001] The invention relates to a processing method of a polypropylene luminous rope for agricultural science and fishery technology. Background technique [0002] Rope is a widely used material in technical fields such as fishing, construction, transportation and military. There are many ways to classify ropes. According to their scope of use, they can be divided into fishing ropes, construction ropes, marine ropes and military ropes, etc.; 12.0mm≤rope diameter≤20.0mm) ropes and large-size (rope diameter>20mm) ropes, etc.; according to their functions, they can be divided into ordinary ropes, high-strength ropes and luminous ropes. Small-sized fishing ropes with a diameter of 4mm to 12mm are widely used in fishery production. They can be used for binding ropes for cage handrails, net cage net bag handrails, and binding ropes for fixed fishing gear; ordinary synthetic fiber ropes There is no luminous function, and the water part of the net cage or fixed ...

AI Technical Summary

Problems solved by technology

There is an essential difference between the technology of using PP resin as the masterbatch to produce fishery blended modified polypropylene luminous yarn and the technology of using HDPE resin as the masterbatch to produce fishery polyethylene luminous yarn. Silk technology and rope making process cannot produce small-sized blended modified polypropylene luminescent
