Description
FIELD OF THE INVENTION
[0001] The invention relates to the field of application of polymer
materials and particularly relates to a high-strength rigging and a
preparation method thereof.
BACKGROUND OF THE INVENTION
[0002] Ultra-high molecular weight polyethylene (UHMW-PE for short)
is a thermoplastic engineering plastic with a linear structure and
excellent comprehensive performances, and one of important uses of
the material is to prepare a high-strength fiber on the basis of
the material.
[0003] An ultra-high molecular weight polyethylene (UHMW-PE) fiber
is a high-performance fiber, has the advantages of high strength,
wear resistance, impact resistance, corrosion resistance, UV
resistance and the like and is widely applied to preparation of
hoisting riggings, hawsers, force-bearing riggings, heavy-duty
riggings, salvaging riggings, drag riggings, sailboat riggings,
fishing lines, mooring anchor riggings for ocean operation
platforms and other various riggings. The breaking length of the
rigging prepared on the basis of ultra-high molecular weight
polyethylene fibers under dead weight is about 8 times of that of a
steel wire rigging and is about 2 times of that of an aramid fiber
rigging, thereby having excellent performances.
[0004] The rigging based on the ultra-high molecular weight
polyethylene fibers is generally prepared by twisting, weaving or
converging through an outer sleeve N ultra-high molecular weight
polyethylene fiber. As the ultra-high molecular weight polyethylene
fiber has a silk-like structure (the fiber number of the single
yarn is about 2.5 deniers), so that in the process of preparing the
various riggings based on the ultra-high molecular weight
polyethylene fiber, multiple fibers with the silk-like structures
need to be finished respectively, the process is complex, and the
cost is high; and furthermore, in the preparation process of the
product, the surfaces of the fibers are liable to production of
burrs due to friction, and the fibers are liable to breaking,
distortion, intertwining and other phenomena, thereby being not
conductive to realizing integral uniform stress of the multiple
fibers, resulting in that the integral strength of the prepared
rigging is often lower than the sum of the strength of N ultra-high
molecular weight polyethylene fibers, and the strength utilization
ratio is relatively low.
SUMMARY OF THE INVENTION
[0005] A brief summary of the invention is given below to
facilitate the basic understanding of some aspects of the
invention. It should be understood that the summary is not an
exhaustive summary of the invention. It is not intended to
determine key or important parts of the invention or limit the
scope of the invention. It only aims at presenting some concepts in
a simplified form as a prelude to the more detailed description
which will be discussed later.
[0006] The invention provides a high-strength rigging with simple
process and relatively low cost and a preparation method
thereof.
[0007] The invention provides a preparation method of a
high-strength rigging, at least comprising the following step:
preparing a body of the high-strength rigging from an ultra-high
molecular weight polyethylene thin film or strip.
[0008] Optionally, preparing the body from the ultra-high molecular
weight polyethylene thin film or strip comprises: converging or
converging and twisting the ultra-high molecular weight
polyethylene thin film or strip into a single yarn to obtain the
body.
[0009] Optionally, preparing the body from the ultra-high molecular
weight polyethylene thin film or strip comprises: integrally
arranging multiple single yams to form the body, wherein each
single yam is prepared by converging or converging and twisting the
ultra-high molecular weight polyethylene thin film or strip.
[0010] Optionally, integrally arranging the multiple single yarns
comprises: converging, twisting or weaving the multiple single yams
into a whole.
[0011] Optionally, the body is prepared by plying multiple yarn
strands, wherein each yarn strand comprises multiple single yarns,
and each single yarn is prepared by converging or converging and
twisting the ultra-high molecular weight polyethylene thin film or
strip.
[0012] Optionally, all the single yarns in each yarn strand are
converged, twisted or woven into a whole.
[0013] Optionally, plying the multiple yarn strands comprises:
converging, twisting or weaving the multiple yarn strands into a
whole.
[0014] Optionally, the ultra-high molecular weight polyethylene
thin film or strip is converged along the straightening direction
of a molecular chain thereof.
[0015] Optionally, the single yarn is converged along the
straightening direction of a molecular chain of the ultra-high
molecular weight polyethylene thin film or strip.
[0016] Optionally, the yarn strands are converged along the
straightening direction of a molecular chain of the ultra-high
molecular weight polyethylene thin film or strip.
[0017] Optionally, the related parameters of the ultra-high
molecular weight polyethylene thin film at least meet one or more
of the following conditions:
the linear density is above 5000 deniers; the width is above 100
mm; the thickness is below 0.2 mm; the breaking strength is above
10 grams/denier; the tensile modulus is above 800 grams/denier; and
the elongation at break is below 6%.
[0018] Optionally, the related parameters of the ultra-high
molecular weight polyethylene strip at least meet one or more of
the following conditions:
the linear density is above 100 deniers; the width is 1-100 mm; the
thickness is below 0.2 mm; the breaking strength is above 10
grams/denier; the tensile modulus is above 800 grams/denier; and
the elongation at break is below 6%.
[0019] The invention further provides a high-strength rigging,
prepared by adopting the preparation method of the high-strength
rigging.
[0020] The body of the high-strength rigging provided in each
embodiment of the invention is prepared on the basis of the
ultra-high molecular weight polyethylene thin film or strip. In the
preparation process of the body, the ultra-high molecular weight
polyethylene thin film or strip is treated as a whole, thereby
having good structural integrity, being simple in preparation
process, eliminating a complex process for respectively finishing
multiple fiber silks, obviously reducing the probability of
producing burrs on the surface of the thin film or strip and also
obviously reducing the probability of breaking, distortion,
intertwining and other phenomena in the thin film or strip. When
the rigging including the body bears a load, the ultra-high
molecular weight polyethylene thin film or strip is stressed as a
whole, so that the strength of the rigging is relatively high and
the strength utilization ratio is effectively improved.
[0021] Thus, the strength of the rigging prepared on the basis of
the ultra-high molecular weight polyethylene thin film or strip is
higher than that of a product prepared by adopting the ultra-high
molecular weight polyethylene fiber with the same denier number,
the cost of the former is obviously lower than that of the latter,
and the rigging has the advantages of good structural integrity,
high strength, high strength utilization ratio, high production
efficiency, low processing cost, light weight, small surface
density, good flexibility and the like.
[0022] These and other advantages of the invention will be more
evident through the following detailed description of optional
embodiments of the invention in conjunction with the accompanying
drawings.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0031] The exemplary embodiments of the invention will be described
in detail below in conjunction with the accompanying drawings. For
clarity and brevity, not all the characteristics of the actual
implementation ways are described in the description.
[0032] However, it should be understood that, in the process of
developing any of these actual embodiments, many decisions which
are specific to the implementation ways must be made to facilitate
achieving specific objectives of development persons, such as
meeting those system and business related limitation conditions,
and these limitation conditions may vary between different
implementation ways. In addition, it should also be understood
that, although the development work may be very complex and
time-consuming, such development work is just a routine task for
those skilled in the art benefiting from the disclosure of the
invention.
[0033] Here, it still needs to be noted that, in order to prevent
unnecessary details from obscuring the invention, only the device
structure and/or the treatment steps which are closely related to
the solutions of the invention are described in the accompanying
drawings and the description, and the expressions and the
descriptions of the parts and the treatments which are not closely
related to the invention and are known to those of ordinary skill
in the art are omitted.
[0034] Ultra-high molecular weight polyethylene is polyethylene
with molecular weight of above 1 million. The traditional
technologies of ultra-high molecular weight polyethylene
application take ultra-high molecular weight polyethylene fibers as
the basis to prepare various products. The technical solutions
provided by the various embodiments of the invention are
essentially different from the traditional technologies of
ultra-high molecular weight polyethylene application and are
revolutionary innovations against the traditional technologies, and
the core concept mainly comprises: the various riggings are
prepared by using the ultra-high molecular weight polyethylene thin
film or strip to replace the traditional ultra-high molecular
weight polyethylene fibers.
[0035] In this case, as shown in FIG. 1, the ultra-high molecular
weight polyethylene thin film is a thin slice which is prepared
from ultra-high molecular weight polyethylene and has a certain
width and thickness, wherein the width is much greater than the
thickness. As shown in FIG. 2, the strip is a strip-like thin slice
which can be prepared independently or be formed by performing
slitting process step before and after stretching the thin film,
wherein the width of the strip is less than the width of the thin
film, and the thickness thereof is equivalent to that of the thin
film or greater than the thickness of the thin film.
[0036] The ultra-high molecular weight polyethylene thin film or
strip provided by the invention is different from the ultra-high
molecular weight polyethylene fibers and also different from a
plane formed by bonding multiple ultra-high molecular weight
polyethylene fibers, and the significant difference is that the
ultra-high molecular weight polyethylene thin film or strip
provided by the invention has a certain width and thickness and has
an integral structure without integration points or trim lines.
[0037] The body of the high-strength rigging provided in each
embodiment of the invention is prepared on the basis of the
ultra-high molecular weight polyethylene thin film or strip. In the
preparation process of the body, the ultra-high molecular weight
polyethylene thin film or strip is treated as a whole, thereby
having good structural integrity, being simple in preparation
process, eliminating a complex process for respectively finishing
multiple fiber silks, obviously reducing the probability of
producing burrs on the surface of the thin film or strip and also
obviously reducing the probability of breaking, distortion,
intertwining and other phenomena in the thin film or strip. When
the rigging including the body bears a load, the ultra-high
molecular weight polyethylene thin film or strip is stressed as a
whole, so that the strength of the rigging is relatively high and
the strength utilization ratio is effectively improved.
[0038] Thus, the strength of the rigging prepared on the basis of
the ultra-high molecular weight polyethylene thin film or strip is
higher than that of a product prepared by adopting the ultra-high
molecular weight polyethylene fiber with the same denier number,
the cost of the former is obviously lower than the latter, and the
rigging has the advantages of good structural integrity, high
strength, high strength utilization ratio, high production
efficiency, low processing cost, light weight, small surface
density, good flexibility and the like.
[0039] The technical solutions of the invention are further
described below by taking the optional structures of the rigging
and the preparation method thereof as examples in conjunction with
the accompanying drawings.
Embodiment 1
[0040] As shown in FIG. 3, the embodiment provides a preparation
method of a high-strength rigging, at least comprising the
following step:
step S101: preparing a body of the high-strength rigging from an
ultra-high molecular weight polyethylene thin film or strip.
[0041] In addition to the body, the high-strength rigging provided
in each embodiment of the invention may comprises a sheath and
other structures, and the body is a main part for bearing
force.
[0042] Preparing the body of the high-strength rigging from the
ultra-high molecular weight polyethylene thin film or strip
specifically comprises: converging the ultra-high molecular weight
polyethylene thin film or strip to prepare a single yarn and using
the prepared single yarns to replace traditional ultra-high
molecular weight polyethylene fibers to prepare the rigging, for
example, various wires, riggings, strips and the like.
[0043] In addition, the ultra-high molecular weight polyethylene
thin film or strip can also be used for directly replacing the
traditional ultra-high molecular weight polyethylene fibers to
prepare the rigging, for example, multiple ultra-high molecular
weight polyethylene strips are laminated to obtain a strip-like
rigging.
[0044] The related parameters of the ultra-high molecular weight
polyethylene thin film in each embodiment of the invention at least
meet one or more of the following conditions: the linear density is
above 5000 deniers; the width is above 100 mm; the thickness is
below 0.2 mm; the breaking strength is above 10 grams/denier; the
tensile modulus is above 800 grams/denier; and the elongation at
break is below 6%. By preparing the rigging on the basis of the
ultra-high molecular weight polyethylene thin film with one or more
of the priggingrties described above, the rigging has higher
integral strength and can meet the preparation requirements of
high-strength load, bulletproof and other products.
[0045] The related parameters of the ultra-high molecular weight
polyethylene strip provided in each embodiment of the invention at
least meet one or more of the following conditions: the linear
density is above 100 deniers; the width is 1-100 mm; the thickness
is below 0.2 mm; the breaking strength is above 10 grams/denier;
the tensile modulus is above 800 grams/denier; and the elongation
at break is below 6%. By preparing the rigging on the basis of the
ultra-high molecular weight polyethylene strip with one or more of
the priggingrties described above, the rigging has higher integral
strength and can meet the preparation requirements of high-strength
load, bulletproof and other products.
[0046] According to the high-strength rigging in the embodiment,
the ultra-high molecular weight polyethylene thin film or strip is
adopted to prepare the body, and the ultra-high molecular weight
polyethylene thin film or strip has an integral structure without
integration points or trim lines and is different from the
silk-like structure of the ultra-high molecular weight polyethylene
fiber in the prior art, so that in the preparation process of the
rigging, the ultra-high molecular weight polyethylene thin film or
strip is treated as a whole, a complex process for respectively
finishing multiple fiber silks is eliminated, and the probability
of breaking, distortion, intertwining and other phenomena in the
thin film or strip is obviously reduced.
[0047] When the rigging prepared on the basis of the ultra-high
molecular weight polyethylene thin film or strip bears a load, the
ultra-high molecular weight polyethylene thin film or strip is
stressed as a whole, so that the strength of the rigging is
relatively high and the strength utilization ratio is effectively
improved. Thus, the strength of the rigging adopting the ultra-high
molecular weight polyethylene thin film or strip is higher than
that of the rigging prepared by adopting the ultra-high molecular
weight polyethylene fiber with the same denier number, and the cost
of the former is obviously lower than the latter.

placing the ultra-high molecular weight polyethylene thin film or

401 are woven into a whole, and the method specifically comprises:
placing the multiple single yarns on a weaving machine for weaving,
wherein the number of the single yarns can be set according to
need, and the body prepared in this way can be applied to guide
riggings of helicopters, suspension riggings on deceleration
parachutes and aircrafts, electric traction riggings, ship mooring
riggings, cable riggings, anchoring riggings, tank drag riggings,
mooring anchoring riggings, crashproof poles, cable reinforcing
cores and the like.
[0069] After testing, when the body prepared from the ultra-high
molecular weight polyethylene thin film or strip has a diameter of
about 10 mm, the breaking load (the load at break) can be above 8.5
tons, the production cost is low, and in addition, the body has the
advantages of light weight, corrosion resistance, wear resistance,
ultraviolet resistance, long service life, portability and the
like.
Embodiment 5
[0070] The embodiment provides a high-strength rigging, which at
least comprises a body prepared from an ultra-high molecular weight
polyethylene thin film or strip, the body comprises multiple single
yarns, each single yarn is prepared by converging the ultra-high
molecular weight polyethylene thin film or strip, or each single
yarn is prepared by converging and twisting the ultra-high
molecular weight polyethylene thin film or strip.
[0071] Optionally, as shown in FIG. 6, a hoisting strip comprises a
sheath 501 and a bearing core 502, the body is the bearing core of
the hoisting strip, the body has a strip-like structure, the
multiple single yarns are woven into a whole to obtain the body,
and the method comprises: placing the multiple single yarns on a
weaving machine for weaving, and the number of the single yarns can
be set according to need.
[0072] When the hoisting strip prepared from the ultra-high
molecular weight polyethylene thin film or strip bears the load,
the ultra-high molecular weight polyethylene thin film or strip is
stressed as a whole, so that the strength of the hoisting strip is
relatively high, and the strength utilization ratio is effectively
improved. Thus, the strength of the hoisting strip prepared from
the ultra-high molecular weight polyethylene thin film or strip is
much higher than that of the hoisting strip prepared from
ultra-high molecular weight polyethylene fibers with the same
denier number, and the cost of the former is obviously lower than
the latter.
Embodiment 6
[0073] The embodiment provides a high-strength rigging, which at
least comprises a body prepared from an ultra-high molecular weight
polyethylene thin film or strip, the body comprises multiple yarn
strands, each yarn strand comprises multiple single yarns, each
single yarn is prepared by converging an ultra-high molecular
weight polyethylene thin film or strip, or each single yarn is
prepared by converging and twisting the ultra-high molecular weight
polyethylene thin film or strip.
[0074] As an optional implementation way, the body is a bearing
core of a hoisting strip, and the body has a strip-like
structure.
[0075] Optionally, the multiple single yams included in each yarn
strand are converged into a whole.
[0076] Optionally, the multiple single yams included in each yam
strand are twisted into a whole.
[0077] Optionally, the multiple single yams included in each yam
strand are woven into a whole.
[0078] Optionally, the multiple yam strands are woven into a whole
to obtain the body, and the method specifically comprises: placing
the multiple yarn strands on a weaving machine for weaving, and the
number of the yam strands can be set according to actual
requirements.
[0079] When the hoisting strip prepared from the ultra-high
molecular weight polyethylene thin film or strip bears the load,
the ultra-high molecular weight polyethylene thin film or strip is
stressed as a whole, so that the strength of the hoisting strip is
relatively high, and the strength utilization ratio is effectively
improved. Thus, the strength of the hoisting strip prepared from
the ultra-high molecular weight polyethylene thin film or strip is
much higher than that of the hoisting strip prepared from
ultra-high molecular weight polyethylene fibers with the same
denier number, and the cost of the former is obviously lower than
the latter.
