Description

technical field [0001] The invention relates to the field of cables, in particular to a cable sheath material with a flame-retardant function. Background technique [0002] Electricity is the energy guarantee to ensure people's life, production, work and study, and electricity is transported to thousands of households through cables. The cable is a rope-like cable twisted by several or groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. The entire outer surface is covered with high insulation. the covering layer. With the development of the economy, the places where cables need to be used have become diversified, and the performance of cable sheath materials has been marked with more stringent and diverse requirements, such as insulation, tensile strength, operating temperature, flame retardancy, etc. There are strict requirements for the use of standards, and continuous improvement ...

Problems solved by technology

With the development of the economy, the places where cables need to be used have become diversified, and the performance of cable sheath materials has been marked with more stringent and diverse requirements, such as insulation, tensile strength, operating temperature, flame retardancy, etc. There are strict requirements for the use of standards, 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, poor chemical stability, high temperature deformation, poor mechanical properties, and use Problems such as short life have brought a lot of inconvenience to actual use, and even threatened people's lives and property safety. Therefore, it is urgent to change the original sheath material formula and improve material performance to meet the diverse needs of the cable market.
