Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a highly wear-resistant modified polyurethane cable material. Background technique [0002] Polyurethane elastomer refers to a type of elastomeric polymer containing more carbamate functional groups on the main chain of the macromolecule. It is a typical multi-block copolymer, usually composed of oligomer polyols (polyether or polyester) ) is first prepared by addition reaction with polyisocyanate, and then reacted with chain extender. Polyurethane elastomer has excellent wear resistance, maintains high elasticity in a wide range of hardness, high strength and high elongation, good oil resistance and resistance to various solvents, high tear strength, low temperature resistance , Has been widely used in mines, oil fields, machinery, textiles, automobiles, cables and other fields. [0003] The environment in which the existing cables are in service is generally relativel...
