Abstract

The invention discloses a high-strength and durable polypropylene rope and a manufacturing method thereof. The rope comprises a rope core and main rope strands, wherein the rope core comprises a metalyarn rope and a waterproof rubber layer which wraps the metal yarn rope; each main rope strand is twisted by polypropylene fibers, steel wires and polyamide fibers, and the main rope strands are twisted around the rope core to form a rope body. The manufacturing method includes: manufacturing the metal yarn rope, manufacturing the waterproof rubber layer, manufacturing the rope core, manufacturing the main rope strands and forming the rope body. The high-strength and durable polypropylene rope has the advantages that the rope core of the rope is less prone to rusting and rot, the bending resistance and the pressure resistance of the rope body are increased, the main rope strands twisted by the polypropylene fibers, the steel wires and the polyamide fibers in a mixed manner are twisted outside the rope core, and the rope is high in strength, low in elongation percentage and resistant to wear.

Description

technical field [0001] The invention belongs to the technical field of plastic ropes, and in particular relates to a high-strength and durable polypropylene rope and a manufacturing method thereof. Background technique [0002] Rope is widely used in both life and industrial production. The service life of the rope is a major factor in determining the value of the rope. In many cases, the rope plays the role of positioning and fixing. At this time, the rope itself needs to have Due to the small extension nature, due to the material problem, the traditional plastic rope is easy to break due to friction during use, and then due to the cascade effect, a rope will soon be broken and damaged, losing its use value, and Traditional plastic ropes have a large elongation rate and are highly elastic when used, which is not conducive to fixing objects. Contents of the invention [0003] In order to solve the problem that the traditional polypropylene rope is easy to break and has a ...
