Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a high-efficiency flame-retardant cable material and a preparation method thereof. Background technique [0002] Cable is a wire product used to transmit electric energy, magnetic energy, information and realize electromagnetic energy conversion. The cable is mainly composed of a conductor, a conductor shield, an insulation layer, an insulation shield, a buffer layer, a metal sheath, and an outer sheath. Most of the outer sheaths are located on the outermost layer of the cable to protect the cable. At present, plastics and rubber are mostly used as the main materials. However, the traditional cables have poor flame retardancy and are prone to fire, causing property damage and casualties. Therefore, researchers are paying more and more attention to the problem of poor flame retardancy of cable materials. At first, the improvement of the flame retardant properties of cabl...
