The invention discloses a cable material. The cable material is prepared from, by weight, 90-100 parts of polyethylene, 1-5 parts of stearic acid, 60-80 parts of aluminum hydroxide, 5-10 parts of an ultraviolet light absorber, 0.5-4 parts of a coupling agent, 1-10 parts of a stabilizer and 1-5 parts of a plasticizer. The cable material is reasonable in raw material composition and high in flame retardant performance and is low in smoke and non-toxic when being burned, and the prepared cable material has good processability and low-smoke self-extinguishing performance, long service life and good crazing resistance performance.
