Research progress on halogen-free flame retardant polyolefin cable materials and their compatibility with flame retardants
As urbanization proceeds,the demand for power cables to replace overhead lines for energy transmission and distri-bution is increasing,and polyolefin is becoming the main base material for power cables.Polyolefins are flammable material,in order to reduce the fire events caused by cables and considering the environmental requirements,adding halogen-free flame retar-dants to the materials is currently the main way to improve the flame retardancy of polyolefin cable materials.The matrix materials of halogen-free flame-retardant polyolefin cables and their modification methods were summarized,then the classification and flame-retardant mechanism of halogen-free flame-retardants were introduced,and the latest research progress in improving the compatibili-ty between matrix and halogen-free flame-retardants were finally reviewed.
