Wear-resisting high-strength cable and preparation method thereof

Abstract

The invention discloses a wear-resisting high-strength cable produced by a non-single material and a preparation method of the wear-resisting high-strength cable. A cable body is an 8-strand structure core body which is prepared from ultra-high molecular weight polyethylene (UHMWPE) and high-strength polyester according to the amount ratio of 3 to 1; a high-toughness wear-resistant coating woven by adopting vectran fibers is arranged outside the core body; and a wear-resistant coating which is especially made of a wear-resistant material PTFE as a matrix coats the outer surface of the sleeve; the preparation method comprises the following steps: fabricating a cable body by the procedures of preparing roving, preparing rope yarns, infiltrating resin, preparing rope strands, braiding ropes, prestretching and drying; weaving a high-strength wear-resisting sleeve on the surface of the core body; and dipping and coating a wear-resisting coating which is especially prepared from PTFE as a matrix on the outer layer of the sleeve.

Description

technical field [0001] The invention relates to a wear-resistant high-strength cable produced by non-single material and a preparation method thereof. Background technique [0002] The performance requirements of cables are high strength, light weight, small diameter, low elongation, wear resistance, weather resistance, chemical corrosion resistance, aging resistance, low water absorption, light operation, durability, and high safety. In the cable manufacturing process, on the one hand, the fiber materials selected, such as cotton, hemp, polypropylene, polyester, nylon, ultra-high molecular weight polyethylene, steel wire, etc., have their own shortcomings. Cotton and linen are not high in strength, polypropylene is not resistant to aging, and polyester It sinks heavily in water, the nylon elongation is too large, the wear resistance of ultra-high molecular weight polyethylene is not as good as that of polyester, and the flexibility of steel wire is not good. On the other h...

[0002] The performance requirements of cables are high strength, light weight, small diameter, low elongation, wear resistance, weather resistance, chemical corrosion resistance, aging resistance, low water absorption, light operation, durability, and high safety. In the cable manufacturing process, on the one hand, the fiber materials selected, such as cotton, hemp, polypropylene, polyester, nylon, ultra-high molecular weight polyethylene, steel wire, etc., have their own shortcomings. The strength of cotton and linen is not high, polypropylene is not resistant to aging, polyester It sinks heavily in water, the nylon elongation is too large, the wear resistance of ultra-high molecular weight polyethylene is not as good as that of polyester, and the flexibility of steel wire is not good

On the other hand, most of them are made of a single fiber material, or the strength is low, or they are not wear-resistant, or they are heavy. The performance often cannot meet the actual needs, and needs to be improved and perfected.
