Abstract

The invention relates to the technical field of cable production, in particular to a production process of a buried cable based on a non-metal biomimetic material and the cable. Comprising the following components in parts by weight: 5-20 parts of composite polythiophene, 30-60 parts of crosslinked polyethylene particles, 5-15 parts of a polyurethane foaming agent, 10-20 parts of silicone rubber, 5-15 parts of carbon fiber cloth, 10-25 parts of epoxy resin, 10-20 parts of a phthalic anhydride curing agent and 5-20 parts of polyolefin particles. The doping agent is adopted to modify polythiophene, so that the conductivity can be improved, the mechanical strength and toughness of the material can be enhanced through interaction with a polymer chain, and the service life of the material in practical application can be prolonged. The boron nitride nanosheets are added, so that the thermal stability of polythiophene can be remarkably improved, and the tensile strength, toughness and impact resistance of the composite material are improved; in addition, the chemical inertness of the boron nitride nanosheet can help to improve the durability of the composite material.
