Problems solved by technology

In order to make the polyethylene fiber for fishery have sufficient breaking strength (greater than or equal to 56cN/tex), it must be fully drawn, but because the polyethylene macromolecular chain structure is highly symmetrical, the polyethylene macromolecular chain height after full drawing Orientation makes its crystallinity larger, which leads to poor toughness of the prepared poly

Abstract

The invention discloses a method for manufacturing a polyethylene fiber for fishing. The method comprises the following steps: uniformly mixing an elastomer and active nano particles, and preparing an elastomer/active nano particle compounded system through extrusion of a double-screw extruder; mixing the prepared compounded system and polyethylene, pelleting through the double-screw extruder, and preparing the master batch; mixing the obtained master batch and polyethylene, and preparing the high-strength high-toughness polyethylene fiber through a melt spinning-high-draft spinning process; and the method is characterized in that the elastomer has the melt index of 0.5-20g/min; the polyethylene melt index is 0.1-20g/min; the material retention time in a screw extruder is 2-3 minutes; the temperature is 150-250 DEG C, and the melt spinning and high-draft spinning process have the parameters of the spinning temperature of 240-350 DEG C, the spinning speed of 5-50m/min, the draft multiple of 8-12 times and the draft temperature of 95-100 DEG C. The method is used for polyethylene fibers for fishing and industrial polyethylene ropes.

Description

technical field [0001] The invention relates to a polyethylene fiber and a production method. Background technique [0002] Polyethylene is the plastic variety with the simplest chemical composition and molecular structure and the largest production volume. Because polyethylene has excellent low temperature resistance, good chemical stability, acid and alkali corrosion resistance, and low water absorption, it is used in aerospace, industry, It has important applications in fishery. Polyethylene fiber is currently mainly used in fishery to make fishing nets, ropes and other fishing gear. Fishery polyethylene fiber is made of high-density polyethylene as raw material, which is prepared into polyethylene monofilament by melt spinning and post-drawing process. In order to make the polyethylene fiber for fishery have sufficient breaking strength (greater than or equal to 56cN / tex), it must be fully drawn, but because the polyethylene macromolecular chain structure is highly sym...
