Problems solved by technology

Since the UHMWPE fiber is a filamentous structure (the linear density of the single filament is about 2.5 denier), so in the process of preparing chemical fiber ropes based on the gel filament fiber of UHMWPE, it is necessary to process the fibers of multiple filamentary structures. Sorting separately, the process is complicated and the cost is high. Compared with chemical fiber ropes made of other materials, the market price is too high, which is not conducive to large-scale application
In addition, in the process of preparing chemical fiber ropes based on ultra-high molecular weight polyethylene fibers, the surface of the fibers is prone to burrs due to friction, and the fibers are prone to breakage, twisting, and entanglement, which is not conducive to the overall uniform force of multiple fibers, resulting in The overall strength of the obtained chemical fiber rope is often lower than the total strength of multiple ultra-high molecular weight polyethylene fibers, and the strength utilization rate is very low

Embodiment 1

[0064] Such as image 3 As shown, the present embodiment provides a method for preparing a rigging, which at least includes the following steps:

[0065] Step S301: The ultra-high molecular weight polyethylene film or strip is bundled or bundled and twisted to obtain a single yarn.

[0066] Step S302: arranging a plurality of single yarns integrally to obtain a bearing core.

[0067] Step S303: thread the load-bearing core into the hollow sheath to make the sling body of the rigging; or, feed the load-bearing core during the process of weaving the sheath with the material for the sheath, so that the sheath is woven around the load-bearing core to make a rigging body. rigging body

[0068] An optional structure of the single yarn in step S301 is shown as figure 2 As shown, the single yarn 201 can be made of UHMWPE film or tape. A better converging process of ultra-high molecular weight polyethylene film or strip For example: put the ultra-high molecular weight polyethylene...

Embodiment 2

[0114] Different from the first embodiment above, in the technical solution provided by this embodiment, a polyurethane resin layer is also formed on the outer surface of the bearing core, and the preferred process steps are as follows: Figure 5 shown, including:

[0115] Step S501: The ultra-high molecular weight polyethylene film or strip is bundled or bundled and twisted to obtain a single yarn.

[0116] Step S502: arranging a plurality of single yarns integrally to obtain a bearing core.

[0117] Step S503: Put the bearing core into the water-based polyurethane resin emulsion, so that the outer surface of the bearing core is soaked in the water-based polyurethane resin emulsion.

[0118] Step S504: drying and shaping the bearing core soaked with the water-based polyurethane resin emulsion, so as to form a polyurethane resin layer on the outer surface of the bearing core.

[0119] Step S505: thread the load-bearing core into the hollow sheath to make the rigging body of ...

Embodiment 3

[0122] This embodiment provides a rigging, the bearing core is 8 braided ropes, and the preparation method is as follows:

[0123] The ultra-high molecular weight polyethylene strips with a linear density of 300 denier, a width of 3 mm, a thickness of 0.02 mm, a breaking strength of 28 g / d, a tensile modulus of 1700 g / d, and an elongation at break of 1.9% are bundled to obtain a single yarn . 53 single yarns are bundled together to obtain a yarn strand. The 8 strands of yarn are braided by a braiding machine, wherein part of the axis of the braider rotates along the S direction to twist the 4 strands of yarn along the S direction (the twist is 15 per meter), and part of the axis of the braider rotates along the Z direction Twist the remaining 4 yarn strands along the Z direction (the twist is 15 pieces / meter), and the twisted yarn strands of each strand are interspersed with each other and interweaved as a whole, thus braiding and making the bearing core. The diameter of the ...

Abstract

The invention relates to a rigging and a preparation method thereof, wherein the rigging comprises a rigging body. The rigging body comprises a carrier core and a sheath sleeved on the periphery of the carrier core. The carrier core comprises a plurality of single yarns disposed integrally, and each single yarn is made by packing or packing and twisting an ultrahigh molecular weight polyethylene film or strip. The technical solution provided by the invention replaces traditional UHMWPE fibers with the single yarns for the preparation of the rigging, and the rigging is high in strength utility ratio of UHMWPE film or strips, easy to process, low in cost and environmentally friendly without glue.

Description

technical field [0001] The invention relates to the application field of polymer materials, in particular to a rigging and a preparation method thereof. Background technique [0002] Chemical fiber ropes are widely used due to their advantages of light weight, high strength and wear resistance, gradually replacing the original application range of natural fiber ropes. [0003] Ultra High Molecular Weight Polyethylene (UHMW-PE) is a thermoplastic engineering plastic with a linear structure and excellent comprehensive properties. Making high-strength fibers based on this material is one of its important uses. The outstanding advantages of UHMWPE fiber, such as high strength, high modulus, low density, and aging resistance, have also been used in the manufacture of chemical fiber ropes. [0004] The existing ultra-high molecular weight polyethylene chemical fiber rope is made of ultra-high molecular weight polyethylene gel filament fiber. Since the UHMWPE fiber is a filamento...
