Abstract

The invention discloses a high-performance PP (polypropylene) fiber rope, comprising a rope body. The rope body includes outer skin and eight rope strands; a filling layer is arranged between the ropebody and the rope strands; the rope strands include an upper layer of three strands, a middle layer of two strands and a bottom layer of three strands; each rope strand is composed of a covering layer and rope cores; any rope strand is formed by twisting 12 rope cores; the high-performance PP fiber rope is composed of the eight rope strands; each rope strand is formed by twisting 12 rope cores, with 10 rope cores around 2 rope cores, wherein the rope cores are twisted in pairs in opposite directions; rotation of the rope can be prevented through such manner; the high-performance PP fiber ropeis more convenient to use; steel wires in the rope cores can provide shaping; the covering layers made of acrylic material allow less water to enter the rope cores, and therefore, rusting of the steel wires is avoided.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-performance PP fiber cable. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene. According to the position of the methyl group, it is divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. The copolymer type PP material has a lower heat distortion temperature ( 100°C), low transparency, low gloss, and low rigidity, but it has stronger impact strength. The impact strength of PP increases with the increase of ethylene content. The Vicat softening temperature of PP is 150°C. Due to the high degree of crystallinity, this material has very good surface stiffness and scratch resistance properties. PP does not have the problem of environmental stress cracking, so many companies use PP fibers to make cables, but the overall performance is not enough to meet actual needs...
