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...

Benefits of technology

[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.

Problems solved by technology

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.
