Description

technical field [0001] The invention relates to the technical field of power cable protective materials, in particular to a modified polyvinyl chloride power cable protective material. Background technique [0002] Power cable protection materials are mainly installed underground or on the ground to protect cables from corrosion or damage, and to prevent short-circuit accidents caused by disconnection of power lines. Power cable protective materials generally need to be applied in various harsh environments, including seabed, snow and saline-alkali environment, etc. The materials for preparing power cables should have high heat resistance, insulation performance, compression resistance, impact strength, and flame retardancy, and the power cable protective material should be light in weight, high in strength, simple in construction and laying methods, and long in service life. [0003] Polyvinyl chloride is a thermoplastic resin polymerized by vinyl chloride under the action...
