A fireproof material for fireproof electric wire pipes is provided to reduce manufacturing costs of fireproof electric wire pipes and to improve fire retardancy of fireproof electric wire pipes by preparing fireproof electric wire pipes without covering of flame retardant material on non-flammable wire pipe. A fireproof material for fireproof electric wire pipes comprises high density polyethylene F00-70 30~40 weight%, DECA 83R 40~50 weight%, antimony trioxide(Sb2O3) 10~20 weight%, and coupling agent 3~8 weight% based on the total weight 100 weight%. A method for manufacturing the fireproof electric wire pipes comprises the steps of: adding the fireproof material 6 weight% to materials 94 weight% for normal wire pipes and mixing them; and preparing the fireproof electric wire pipes by using the mixture.
