Manufacturing method of high-tensile-strength ultrahigh-molecular-weight polyethylene mining rope

Abstract

The invention discloses a manufacturing method of a high-tensile-strength ultrahigh-molecular-weight polyethylene mining rope. The high-tensile-strength ultrahigh-molecular-weight polyethylene miningrope consists of polyethylene, a chlorosulfonic acylating agent, an organic peroxide, unsaturated silane and glass fibers. The preparation method of the high-tensile-strength ultrahigh-molecular-weight polyethylene mining rope comprises the following steps. According to the manufacturing method of the high-tensile-strength ultrahigh-molecular-weight polyethylene mining rope, firstly, a catalytic reaction is carried out on polyethylene, sulfur dioxide and chlorine, then cross-linking is carried out with unsaturated silane, and finally glass fibers are added for blending modification, so that the final finished product has very high tensile strength, and the tensile property of the rope made by the finished product is enhanced. Light resistance, wear resistance and tensile strength of the finished product are optimized, and meanwhile, through cross-linking with the unsaturated silane, environmental stress cracking resistance and mechanical properties of the finished product can be improved.

Description

technical field [0001] The invention relates to the technical field of industrial production, in particular to a method for manufacturing an ultra-high molecular weight polyethylene mining rope with high tensile strength. Background technique [0002] Polyethylene is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low temperature resistance. Chemical Good stability, resistant to most acid and alkali erosion, insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation. [0003] Polyethylene can be denatured and drawn with other compounds and finally made into ropes to meet people's use requirements. Since the molecular chain of polyethylene is a flexible chain, and there is no polar group, the attraction between molecular chains is small, so the mechanical propertie...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a method for manufacturing a high-tensile-strength ultra-high molecular weight polyethylene mining rope, which solves the problem that the polyethylene molecular chain is a flexible chain and has no polar groups. The small attraction makes the mechanical properties of polyethylene average, the tensile strength of polyethylene is relatively low, the surface hardness is not high, and the creep resistance is poor
