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...

AI Technical Summary

Benefits of technology

This invention is about a strong and simple rigging made from a thin film or strip made of ultra-high molecular weight polyethylene. It is a high-strength rigging that is cost-effective and easy to prepare. The strength of the rigging is relatively high and the strength utilization ratio is improved. 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.
