AI Technical Summary

Problems solved by technology

The above-mentioned cable material has good mechanical strength, but it is only suitable for conventional indoor and outdoor environment requirements, and will melt and deform at high temperature, and the leakage of the cable conductor is likely to cause safety hazards
It is difficult to pass the high-temperature impact test required in cables or optical cables and the mineral oil immersion test in GB / T2951.21-2008, which limits the application of such traditional cable materials

Abstract

The invention discloses a novel cold-resistant flame-retardant material. The novel cold-resistant flame-retardant material comprises the following substances in parts by weight: 50-60 parts of polybenzimidazole, 40-52 parts of polyetheretherketone, 20-30 parts of (Ba0.7Zn0.3)TiO3, 3-7 parts of antioxidant, 4-8 parts of anti-aging agent, 4-10 parts of compatibilizer, 2-4 parts of cross-linker, 1-3parts of cross-linking assistant and 1-3 parts of flame retardant, wherein a high-temperature resisting temperature of the novel high-temperature resistant flame retardant material is 250 DEG C. According to the novel cold-resistant flame-retardant material, a polybenzimidazole-polyetheretherketone blend serves as a matrix, and the melting point temperature rises, so that an available temperaturerange is widened, and the requirements on resistance to high temperatures above 200 DEG C can be met; an outer layer of the polybenzimidazole-polyetheretherketone blend is coated with (Ba0.7Zn0.3)TiO3, so that flame retardance is facilitated; and (Ba0.7Zn0.3)TiO3 has a relatively high dielectric constant and thus can exert an excellent insulating action.
