Abstract

The invention discloses a flame-retardant aging-resistant cable material which is composed of tetrafluoroprene rubber, maleic anhydride grafted ethylene-vinyl acetate copolymer, EPDM rubber, fumed silica, mica powder, ammonium polyphosphate, melamine borate, nano zinc oxide, dilauryl thiodipropionate, antiager, antioxidant 1010, monoglyceride stearate, silane coupling agent, trioctyl trimellitate, tetrabutyl titanate, turpentine oil and ultraviolet absorber. The invention further discloses a preparation method of the flame-retardant aging-resistant cable material. The flame-retardant aging-resistant cable material prepared by the method combines the advantages of the tetrafluoroprene rubber, the maleic anhydride grafted ethylene-vinyl acetate copolymer and the EPDM rubber and has good mechanical performance; by reasonably adjusting components, the cable material has good flame-retardant effect and aging-resistant effect, service life of cables is prolonged, and the cable material has wide market prospect.

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 and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. Cable material production enterprises take cable production enterprises as users, as long as there is a demand for wire and cable, there will be a market for cable materials. Except for bare wire products such as steel-cored aluminum stranded wire and electromagnetic wire, almost all wire and cable products require an insulation layer. At present, there are nearly 5,000 wire and cable production enterprises in my country, and there is also a huge demand for wire and cable products for urban and rural power grid transformation, western development, and large-scale upgrading of communication facilities. Therefore, ...
