[0002] With the continuous development of power engineering, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of cable sheath materials, such as insulation, tensile strength, operating temperature, and flame retardancy. There are strict requirements on indicators such as sheath materials, and continuous improvement of the performance of sheath materials is an urgent need for economic and social development. Traditional sheath materials often have poor flame retardancy, low mechanical strength, poor corrosion resistance, high temperature deformation, Problems such as poor mechanical properties and short service life bring a lot of inconvenience to actual use, and are likely to bring potential safety hazards, electric shocks or fires. Therefore, how to improve the existing cable sheath materials, complete formula and preparation process is our urgent technical issues to be resolved
