Technique for preparing polypropylene abrasion-proof fabric riata

Abstract

The process for preparing polypropylene wear-resistant fiber ropes relates to the ropes manufacturing, wherein problems to be resolved are to improve preparing process for fibre ropes, to improve wear-resistant performances of fibre material, and to reach the goal of improving wear-resistant performances of ropes. The present invention melting and extruding a resin material into fibres through a plastic extruder is characterized in that: a polypropylene resin material and a wear-resistant master batch are mixed together according to a certain proportion of that the weight of the wear-resistant master batch is 1-3% of weight of the polypropylene resin material, wherein the wear-resistant master batch is prepared by mixing polyethylene with amount of more than 8% and silane with amount of more than 10% into the polypropylene master batch and then stirring them uniformly; the polypropylene resin material and the wear-resistant master batch are extruded after they are co-mixed according to the certain proportion, and the extruded melted fibre is then cooled, tensioned, formed and wound; manufacturing a rope at a strand machine, using 3000D10 fibres, with a twist of 15 twist / meter; manufacturing a rope at a strand machine, using 3 strands, with a twist of 33 twist / meter.

Description

Technical field: [0001] The present invention relates to rope manufacturing technology. Background technique [0002] The damage of the rope mainly comes from wear and tear, so the service life of the rope mainly depends on the wear resistance of the rope. Polypropylene rope has a large friction coefficient, poor wear resistance, and is easily damaged by severe friction. Existing wear-resistant fiber ropes are obtained by the following methods: For example, the strong multi-dimensional polypropylene rope is extruded into fibers by polypropylene and twisted and twisted with the rope yarn, and then the fiber bundles are formed into strands. The fiber bundles of each rope are at least three strands, And a temperature-resistant and wear-resistant material is wound inside and outside each fiber bundle. The disadvantage of this method is that the temperature-resistant and wear-resistant materials cannot be evenly wound on the polypropylene fiber bundle, resulting in uneven wear-...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the temperature-resistant and wear-resistant materials cannot be evenly wound on the polypropylene fiber bundle, resulting in uneven wear-resistant life and poor wear-resistant effect of the rope yarn and strand rope, not only the process is complicated, but the manufacturing cost is high. , and because of the large proportion of temperature-resistant and wear-resistant fibers, the proportion of the rope is greatly increased

To prevent the rope from falling into the water and entangle the propeller, the marine rope needs to have a specific gravity smaller than the water to float in the water. The rope with a large specific gravity has the disadvantage of limited use
