Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-strength and highly flame-retardant modified polyethylene cable material. Background technique [0002] Polyethylene is a kind of thermoplastic resin obtained by direct polymerization of ethylene monomer. It is the most productive general-purpose synthetic resin, mainly including high-pressure low-density polyethylene, low-pressure high-density polyethylene, medium-density polyethylene and some products with special properties. . Polyethylene is non-toxic, odorless, good chemical stability, resistant to most acid and alkali corrosion, insoluble in common solvents at room temperature, low water absorption, excellent electrical insulation performance, widely used in the manufacture of films, hollow products, fibers and cables and other fields. However, polyethylene has disadvantages such as low strength, easy deformation, heat resistance, and flammability, which li...
