Abstract

The invention discloses a method for preparing ultra-tensile strength fibers of ultra-high molecular weight polyethylene and isotactic polypropylene blends. In the method, ultra-high molecular weightpolyethylene resins and isotactic polypropylene resins are included. The ultra-high molecular weight polyethylene resins and isotactic polypropylene resins are blended at a certain ratio to form a mixture resin material, and then the resulting mixture resin is placed in an injection molding machine, followed by extrusion and wire drawing, to obtain the ultra-tensile strength fibers of ultra-high molecular weight polyethylene and isotactic polypropylene blends. In the invention, the mixed synthetic resin is easy to prepare fiber filaments, with stable diameter control, uniform thickness, no wire breakage during the preparation process, extremely fast drawing speed, and no deterioration of the environment. The prepared ultra-tensile strength fibers have the tensile strength and modulus not less than the ultra-high molecular weight polyethylene fibers.

Description

technical field [0001] The invention relates to the technical field of raw material preparation of tensile components in wire and cable assemblies, in particular to a preparation method for ultra-high-molecular-weight polyethylene and isotactic polypropylene blend super-tensile strength fibers. Background technique [0002] Ultra-high molecular weight polyethylene fiber is currently a scarce material in the world. The world's annual demand is about  50,000 tons, but the current world production is less than  9,000 tons, and there is a big gap. Experts predict that the annual market demand for ultra-high molecular weight polyethylene fibers will exceed 100,000 tons in the next 10 years, with huge market potential and broad prospects. [0003] Currently, UHMWPE fibers are produced industrially by three foreign companies, DSM, Honeywell, and Toyobo, with a total annual output of less than 9000 tons. [0004] The annual output of ultra-high molecular weight polyethylene fibers...
