Abstract

The invention discloses an environment-friendly cable filler and a preparation method thereof. The environment-friendly cable filler is prepared mainly by mixing polrvinyl chloride resin, phenolic resin, polypropylene, triallyl cyanurate, sillicane coupling agent, titanate, zinc oxide, straw ash, graphite, calcium carbonate, anti-aging agent, flame retardant and lead silicate in a certain mixture ratio. The environment-friendly cable filler has the advantages of stable chemical structure, good gelation performance and strong expanding capability, and cannot be decomposed by microorganisms; the electrical performance of a cable is improved; the service life of the cable is prolonged; and the resources are saved.

Description

technical field [0001] The invention relates to the field of auxiliary materials for cables, in particular to an environment-friendly cable filler and a preparation method thereof. Background technique [0002] The application of high-voltage power cables in my country is very common and extensive. Most of the high-voltage power cables are laid underground and the environment is mostly humid. Moisture can easily penetrate into the interior of the cable structure. Therefore, under normal high-voltage energization, the theory of electrical stress believes that the internal stress of the cable during production and operation is the main reason for promoting the growth of water branches. When the cable is subjected to voltage and water, in the high-voltage power frequency electric field, the polar water molecules migrate strongly and convert the electric field energy into kinetic energy and heat energy, and the water molecules with huge energy move violently inside the insulatio...
