High temperature resistant anticorrosive cable

Abstract

This invention relates to the field of wire and cable technology, and discloses a high-temperature resistant and corrosion-resistant cable. The cable comprises, from the inside out, a conductor core, an insulation layer, a shielding layer, an anti-corrosion layer, and a high-temperature resistant sheath layer. The insulation layer is made of an insulating composite material, the anti-corrosion layer is formed by coating and curing an anti-corrosion coating, and the high-temperature resistant sheath layer is made of a high-temperature resistant sheath material. The insulation layer uses a matrix resin, a high-temperature resistant modifier, and an insulating reinforcing filler, which are melt-blended to form a dense composite material system. The nanoscale high-temperature resistant modifier is uniformly dispersed in the matrix resin, hindering the thermal movement of the polymer chains and forming a stable protective barrier at high temperatures, thus improving the material's heat resistance and insulation stability. Simultaneously, the insulating reinforcing filler forms a strong interfacial bond with the resin matrix, working together to block the migration path of internal electrons, thereby improving the cable's insulation performance and long-term reliability.
