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 ropes for fishing with good performance
Since the use of PP resin as the masterbatch to produce fishery small-size blended modified polypropylene light-emitting ropes with good performance is still a technical problem in the field of aquatic technology, so far there is no processing method for fishery small-size blended modified polypropylene light-emitting ropes report

Embodiment Construction

[0007] Taking a small-scale blended modified polypropylene luminescent rope with a diameter of 8.8mm as an example, the specific implementation of the present invention is described: the present invention uses PP resin, HDPE resin, luminescent powder, additives, mixer, twin-screw extruder Extruder, single-screw extruder, double-drawing electric heating drawing machine, wire collecting machine, wire dividing machine, twisting machine and rope making machine. After sieving, spin-grade dry T30S PP resin (produced by Daqing Petrochemical, with a melt index of 2.1-3.9g / 10min; if the PP resin is damp, it should be dried in the sun before use), luminescent powder ( Produced by Dalian Luming, PLO-7C type luminescent powder; the amount of luminescent powder added is 10.0% of the weight of PP resin), dry zinc stearate [produced by Shanghai Yan'an Oil Chemical Factory, the zinc content in zinc stearate should meet 10.3~ 11.3%, the molecular formula of zinc stearate is (C 17 h 35 COO) ...

Abstract

A method for processing a small-scale blended modified polypropylene luminous rope for fishing, which relates to a processing method for a luminous rope for fishing. It is necessary to provide a method for processing a small-sized blended modified polypropylene luminous rope for fishing. The present invention uses PP resin, HDPE resin, luminescent powder, additives, characterized in that the mixture of PP resin, luminescent powder, zinc stearate and white oil is extruded and granulated to obtain a blend masterbatch; the blend masterbatch, PP resin The mixture of HDPE resin and HDPE resin is melted and extruded through the extruder, and the melt-extruded as-spun filaments are cooled and pre-drawn, and the pre-drawn filaments are cooled by airflow after two hot drafts. Using blended modified polypropylene luminous filaments, twist 36 luminous filaments to make a "Z" luminous rope yarn, and use 6 "Z" luminous rope yarns to make "S" directional strands, and three strands The "S" strands are twisted in the "Z" direction to make a small-size blended modified polypropylene luminescent rope for fishing. The invention is used for fishing luminescent ropes.

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 ...
