Abstract

The invention discloses a composite nano mining cable sheath material and a preparation method therefor. The cable sheath material comprises hydrogenated polyisobutene, N, N'-m-phenylenedimaleimide, polyvinyl chloride, butyl rubber, a KH570 silane coupling agent, N-phenyl-beta-naphthylamine, magnesium hydrate, nano silicon carbide, nano titanium nitride and brominated bisphenol A epoxy resin. The preparation method comprises the following steps of: (1) taking and adding the hydrogenated polyisobutene, N, N'-m-phenylenedimaleimide, polyvinyl chloride and butyl rubber into an internal mixer to internally mix; (2) then adding the KH570 silane coupling agent, N-phenyl-beta-naphthylamine, magnesium hydrate, nano silicon carbide, nano titanium nitride and brominated bisphenol A epoxy resin to mix; and (3) mixing, tabletting, cutting and cooling strips to obtain the composite nano mining cable sheath material. The prepared composite nano mining cable sheath material has the characteristics of being high in mechanical strength, strong in flame resistance and strong in ageing resistance.
