Description

technical field [0001] The invention relates to the technical field of sheath materials, in particular to a high-performance aging-resistant cable sheath material. Background technique [0002] Wires and cables are widely used in various fields as electric energy and information transmission bodies. Most wires and cables use plastic and rubber as insulation and sheath materials. Such polymer materials will produce flammable gases after being heated, melted and decomposed. At high temperature, these gases will react with oxygen and burn, which will generate a lot of heat, and the heat will promote the further melting, decomposition and continuous burning of the polymer, which will expand the fire and cause huge losses. In my country, the fire loss caused by cables alone is as high as several billion yuan per year. As the flame retardant of wires and cables has attracted more and more attention, people have begun to study various flame retardant materials. In order to improve...
