Abstract

The invention provides an ultra-high molecular weight polyethylene composition. The ultra-high molecular weight polyethylene composition comprises silicon carbide, modified graphene and ultra-high molecular weight polyethylene, wherein the modified graphene is hyperbranched polyethylene grafted graphene. The material prepared from the composition simultaneously has relatively high cutting resistance and very strong tensile strength.

Description

technical field [0001] The invention relates to a polyethylene composition and the prepared high-abrasion-resistant and high-cut-resistance fiber. Specifically, the invention relates to D01F. Background technique [0002] Ultra-high molecular weight polyethylene fiber (UHMWPE) refers to a molecular weight of 1 million to 6 million. Because of its high crystallinity and strong intermolecular forces in its internal structure, it has many excellent properties such as wear resistance, Extremely high impact resistance, chemical corrosion resistance, high noise elimination performance, self-lubrication, low friction coefficient, safety, sanitation and non-toxicity, etc., are known as "magic plastics" and are widely used in Chemical industry, machinery, textile, papermaking, packaging, mining, construction, sports, military, medical and many other fields. [0003] Ultra-high molecular weight polyethylene is a high-performance fiber made by spinning-extracting-drying-super-stretchi...
