Provided is a cable having a sheath composition having flame retardancy and water resistance, and a sheath layer formed of the sheath composition. Specifically, the present invention relates to a sheath composition for simultaneously improving flame retardancy and water resistance of a sheath layer of a cable, which are in a trade-off relation with each other, and physical properties such as heat resistance, hardness, and wear resistance, improving appearance, and reducing manufacturing costs; and a cable having a sheath layer formed of the sheath composition.

Disclosed is a flame-retardant HIPS material and a preparation method thereof, comprising the following components: 90 parts to 67 parts of a HIPS resin; 8 parts to 15 parts of a brominated flame retardant; and 3 parts to 7 parts of an auxiliary flame retardant; wherein the auxiliary flame retardant is a 1,3,5-triazine compound. In the present invention, a synergistic compounding of the brominated flame retardant and the auxiliary flame retardant effectively reduces an amount of the brominated flame retardant, and a stable UL 94 (1.5 mm) V-0 flame-retardant class can be achieved. Compared with the existing brominated flame-retardant HIPS, the present invention has a low halogen content, low gas, and high cost performance ratio, which avoids excessive acid gas from forming air lines on the surface of parts, has a good appearance.
