Preparing method of ultra high molecular weight polyethylene fiber wear-resisting rope

Abstract

The invention relates to a preparing method of an ultra high molecular weight polyethylene fiber wear-resisting rope. The method comprises the steps that ultra high molecular weight polyethylene fiber wires are subjected to plying twisting through a tensioner, and twisted small-strand rope yarn is prepared; the twisted small-strand rope yarn obtained after plying twisting is subjected to strand merging and twisting through the tensioner, and meanwhile polyurethane resin steeping is carried out; then by drier drying, a thick-strand rope is prepared; then the thick-strand rope is twisted into a twisted rope strand; the surface of the twisted rope strand is wrapped with nylon or polyethylene or polyester monofilament; rope strand monofilament wrapping is completed; and finally a rope strand wrapped by monofilament is subjected to alternating twisting to form a rope in the Z twisting direction and the S twisting direction. The prepared ultra high molecular weight polyethylene fiber wear-resisting rope has good abrasion resistance, compared with a public technology, service life is greatly improved, and the method can be widely used in the fields such as sea large ships, naval vessels and harbor towropes.

Description

technical field [0001] The invention relates to a method for making a rope, in particular to a method for preparing an ultra-high molecular weight polyethylene fiber wear-resistant rope. Background technique [0002] Ultra-high molecular weight polyethylene fiber is a high-tech fiber that appeared in the 1990s. Its strength is the highest among all fibers, and its weight ratio is 15 times that of high-quality steel wire. Excellent performance of strong corrosion of similar chemicals; using this fiber to develop high-strength marine engineering ropes has the advantages of high strength, low density, no water absorption, corrosion resistance, and light resistance, but in practical applications, the surface of the rope is fuzzy and the service life is short. In order to improve the wear resistance of the rope surface, the current public technology has adopted the method of coating polyurethane resin on the rope surface and adding a polyester fiber braided sheath to the rope to ...

[0002] Ultra-high molecular weight polyethylene fiber is a high-tech fiber that appeared in the 1990s. Its strength is the highest among all fibers, and its weight ratio is 15 times that of high-quality steel wire. Excellent performance of strong corrosion of similar chemicals; using this fiber to develop high-strength marine engineering ropes has the advantages of high strength, low density, no water absorption, corrosion resistance, and light resistance, but in practical applications, the surface of the rope is fuzzy and the service life is short. In order to improve the wear resistance of the rope surface, the current public technology has adopted the method of coating polyurethane resin on the rope surface and adding a polyester fiber braided sheath to the rope to appropriately reduce the fluffing phenomenon on the rope surface, but through the above two methods After treatment, the fundamental problem cannot be solved
