A composite material used for a special cable, a preparing method thereof and the special cable are disclosed. According to the composite material, polyether ether ketone, polyethylene and polyimide are mixed according to a ratio and adopted as a substrate material, ethylene-vinyl acetate copolymer modified geopolymers, molybdenum trioxide and magnesium oxide are processed by a coupling agent and then adopted as a flame retardant additive, dicumyl peroxide is adopted as a crosslinking catalyst, silicon nitride whiskers are adopted as a fortifier, and the composite material is formed by melting and blending. The composite material has good high-temperature resistance and improved flame retardant effects, and can achieve no performance stability decrease under severe working conditions. In addition, the composite material is used for preparing an outer sheath of the special cable, and durability, fire resistance and stability of the special cable are improved.
