Abstract

The invention relates to an ultra high molecular weight polyethylene rope and a preparation process thereof. The ultra high molecular weight polyethylene rope comprises twelve strands which are braided into a unity. Six strands are left stranding and the other six strands are right stranding. The strands comprise twisted threads of an outer layer, a middle layer, an inner layer, a core layer, and the like which are formed in a twisting way. The twisted threads are high molecular weight polyethylene fiber twisted threads which are twisted according to the diameter of the rope. The preparation process comprises the following steps: 1) raw materials selection; 2) threads twisting; 3) strand preparation; 4) rope preparation; 5) surface treatment. The ultra high molecular weight polyethylene rope has the beneficial effects of corrosion resistance, fatigue resistance, wear resistance, ultraviolet resistance, cable insulation, and the like; besides, the common properties of similar products including small density less than 1, light weight, high strength, good specific modulus and impact resistance strength. The wear resistance is higher than similar products by about 8 percent. The fracture strength is higher than the similar products by 10 percent. And the ultra high molecular weight polyethylene rope has the advantages of reasonable structure, beauty and practicality.

Description

technical field [0001] The invention relates to a preparation process of ultra-high molecular weight polyethylene rope. Background technique [0002] Although ordinary chemical fiber cables on the market also have some basic characteristics such as low density, light weight, high strength, good specific modulus and impact resistance, they do not have corrosion resistance, fatigue resistance, and wear resistance due to unreasonable preparation processes. , UV resistance and cable insulation properties. Contents of the invention [0003] The purpose of the present invention is to provide a preparation process of ultra-high molecular weight polyethylene rope, which overcomes the shortcomings of existing common chemical fiber cables that do not have corrosion resistance, fatigue resistance, wear resistance, ultraviolet resistance and cable insulation. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] An ultra-high...
