Abstract

The invention provides a high-strength composite material used for special cables and a preparation method thereof. In the invention, high-performance engineering-use polyether ether ketone, polyethylene and polyimide are employed as basic polymer materials. Hyperbranched polyurethane is used for modifying molybdenum trioxide and magnesium oxide filling materials and an ethylene-vinyl acetate copolymer is used for modifying silicon nitride and zirconium oxide crystal whiskers, thereby improving binding force between inorganic filling materials and organic substrates. Meanwhile, the hyperbranched polymer penetrates the organic substrate network, thereby improving total strength. The composite material ensures high-temperature resistance, fire-proofing performance and the like and reduces defect generation rate between organic and inorganic interfaces. Compared with special cable materials with non-modified filling materials, the composite material improves strength by more than 33%, thereby effectively improving the durability and reliability of the special cables in use.

Description

technical field [0001] The invention belongs to the field of composite materials for special cables, and in particular relates to a composite material for high-strength special cables and a preparation method thereof. Background technique [0002] With the development of electric power technology, the application fields of cables continue to expand, and the application areas are also increasingly extensive. According to the different use environments, the requirements for the technical parameters of the cables are gradually biased, thus developing a wide variety of special cables with different technical parameters. Common special cables include: fireproof cables, heating cables, environmental protection cables and so on. In the prior art, according to the requirements of special cables, new structures, new materials, and new processes are often used to prepare special cables suitable for the requirements. [0003] In the prior art, the strength of the cable is often impro...
