Problems solved by technology

Although halogenated flame retardants are added to PVC cable materials in the prior art for fire and flame retardancy, PVC will still burn at high temperatures, and will produce a large amount of smoke and irritating toxic gases, which not only pollutes the environment, but also Irritant and toxic gases can endanger human health and even cause cancer
And polyvinyl chloride is exposed to sunlight for a long time, which is easy to age and crack, which affects the insulation of the cable and poses a safety hazard

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a flame-retardant and aging-resistant cable material and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation sheaths are commonly known as cable materials. Cable material production enterprises take cable production enterprises as users. As long as there is a demand for wires and cables, there will be a market for cable materials. Except for bare wire products such as steel cored aluminum stranded wires and electromagnetic wires, all wire and cable products need to be covered with cable materials. At present my country's urban and rural power grid transformation, western development and large-scale upgrading of communication facilities have great demand for wire and cable products, resulting in an increasing demand for cable materials. Cable materials currently have broad market application prospects in my country. [0003] T...
