Abstract
The invention discloses an ultrahigh molecular weight polyethylene abrasion and temperature resistant composite braided rope, relates to a textile rope, and provides an abrasion and high temperature resistant braided rope. Fibers with single density of 1 to 10dtex and ultrahigh molecular weight polyethylene fibers with composite fiber density of 200 to 6,000dtex are merged or twisted into rope yarns with density of 200 to 50,000dtex; the fiber rope yarns with density of 200 to 50,000dtex are merged or twisted into rope strands; the rope strands are braided into an eight-strand or twelve-strand twisted rope or braided rope with a diameter of 1 to 102 millimeters and a linear density of 0.5 to 7,500Ktex; and the twisting coefficient is 3.5 to 10 times diameter of the rope. The composite braided rope is characterized in that: a layer of polytetrafluoroethylene is coated on the outer surface of the rope twisted or braided according to the mode. The composite braided rope is used for engineering with high requirements for abrasion resistance, high temperature resistance and impact fatigue resistance in shipping, spaceflight, military affairs, agriculture, industry and mine sports.
Description
Technical field
The invention belongs to the weaving rope.
Background technology
Because existing ultra-high molecular weight polyethylene (UHMWPE) fibrecord serviceability temperature generally can not superelevation 100 be spent, existing UHMWPE fiber is twisted with the fingers the twisted rope rope for improving wear-resisting and resistance to elevated temperatures, obtain by the following method: adopt metal material to coat on the rope surface during manufacturing, the defective of this method is in hot conditions following service time when longer, and metal will be delivered to heat on the rope of the inside and not have a Wear-resistant, high-temperature resistant effect; And clad material has very big rigidity feature, can only be used in bending radius side significantly, needs the soft engineering of using thereby limited.
Summary of the invention
It is compound volume strand of flexible Wear-resistant, high-temperature resistant or kernmantle that the problem that the present invention need solve provides that a kind of ultra-high molecular weight polyethylene and polytetrafluoroethylene (PTFE) be composited.
Technical scheme of the present invention adopts solid wire density 1dtex-10dtex fiber, and multifilament threads density 200dtex-6000dtex superhigh molecular weight polyethylene fibers merges or twisted becomes 200dtex-50000dtex rope yarn; Become rope strand with merging of 200dtex-50000dtex cordage yarn or twisted; Compile on strand or the kernmantle machine at eight or 12 strands with rope strand and to be woven into diameter 1mm-102mm, line density (Mi Chong) 0.5Ktex-7500Ktex (g/m) stereotyped writing or 12 strands are compiled twisted rope or kernmantle; Twist factor (lay pitch) is 3.5-10 a times of rope diameter, it is characterized in that compiling the macromolecular material polytetrafluoroethylene (PTFE) that twisted rope or kernmantle appearance coating one deck has the Wear-resistant, high-temperature resistant performance in a manner described.
Useful effect of the present invention is that composite rope has the wear-resisting and resistance to elevated temperatures of good softness, anti-wear performance on average improves more than 100% than common UHMWPE fibrecord, and resistance to elevated temperatures improves more than 150 degree than the serviceability temperature of common UHMWPE fibrecord; And impulse fatigue resistance can improve more than 350% than steel wire rope, improves more than 700% than PA or PP fibrecord, improves more than 250% than PET and PPTA fibrecord; Behind this rope ptfe composite, can not influence original every function of use of UHMWPE fibrecord, and kept UHMWPE fibrecord softness characteristics, and can be applied to rope peculiar to vessel such as towing cable mooring and all need twine the less place of radius, can be widely used in towing cable mooring, container ship with other purposes size specification ropes such as traffic shipping, space flight military affairs, industrial or agricultural, mine physical culture such as ropes; Can be applied in the Wear-resistant, high-temperature resistant of special requirement and impact fatigue-resistant performance requirement height again and the inefficient engineering of general fibre rope.
Description of drawings
Accompanying drawing is the cross-sectional structure schematic diagram of ultra-high molecular weight polyethylene and the high temperature resistant sennit of polytetrafluoroethylene (PTFE) complex abrasion-proof.
The specific embodiment
The present invention's (seeing accompanying drawing) adopts polytetrafluoroethylene (PTFE) and solid wire density 1dtex-10dtex fiber, multifilament threads density 200dtex-6000dtex superhigh molecular weight polyethylene fibers; On yarn-twisting machine, merge or milling density 200dtex-50000dtex rope yarn by line density 200dtex-6000dtex superhigh molecular weight polyethylene fibers; Restricting with line density 200dtex-50000dtex, yarn merges on the rope stranding machine or twisted becomes rope strand 1 (seeing accompanying drawing) again; Compile on strand or the kernmantle machine at eight or 12 strands with rope strand, weave into diameter 1mm-102mm, line density (Mi Chong) 0.5Ktex-7500Ktex (g/m) compiles twisted rope or kernmantle for eight or 12 strands; Twist factor (lay pitch) is 3.5-10 a times of rope diameter; On the rope face, apply thick, low melting point (the being lower than 100 ℃) polyethylene of 1mm-2mm earlier with plastic extruder again, and then coat the thick polytetrafluoroethylene (PTFE) 2 of 1mm-5mm (seeing accompanying drawing) at UHMWPE cordage skin.
