Title:
STRESS-RESISTANT, CREEP-RESISTANT, HIGH-TEMPERATURE-RESISTANT AND HIGH-INSULATION SHEATHING MATERIAL FOR MAGNETIC LEVITATION TRAIN CABLES, AND METHOD FOR MANUFACTURING SAME AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/001614
Kind Code:
A1
Abstract:
Provided are a stress-resistant, creep-resistant, high-temperature-resistant and high-insulation sheathing material for magnetic levitation train cables and a method for manufacturing same and use thereof. A functional polyvinyl silicone grease is blended with UHMWPE and a ceramic silicone rubber to serve as a cable material substrate, and multiple chemical crosslinking structures are constructed by means of using electron beam irradiation; in addition, an organic/inorganic filler in the substrate can form physical crosslinking points in the material, and thereby a physical-chemical dual crosslinking structure is constructed in the substrate. A multiple chemical and physical crosslinking structure can limit the movement and relaxation of a molecular chain and improve the interaction between an insulation layer, a sheathing layer, and refractory layers such as a filler and a mica tape, thereby avoiding relative displacement generated in the laying and running processes and improving the high-temperature resistance, creep resistance, and stress relaxation resistance of the UHMWPE cable sheathing material.
