Description

technical field [0001] The invention relates to the technical field of chlorinated polyethylene, in particular to a high flame-retardant chlorinated polyethylene cable material. Background technique [0002] Chlorinated polyethylene has the advantages of excellent flexibility, heat aging resistance, weather resistance and ozone resistance, and the molecular structure contains a considerable proportion of chlorine, so it has good oil resistance, chemical resistance and flame retardancy. Its comprehensive performance is between chloroprene rubber and chlorosulfonated polyethylene, especially chlorinated polyethylene has the characteristics of high insulation resistance and stable dielectric constant under humid conditions, and is one of the commonly used materials in the cable field. [0003] With the development of the economy, the places where cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators ...

Problems solved by technology

[0003] With the development of the economy, 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 materials, such as insulation, tensile strength, service temperature, flame retardancy and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have problems such as poor flame retardancy, poor mechanical properties, and short service life. They often need to be modified to adapt to the cable market. diverse needs
