Halogen-free flame-retardant thin-walled oil-resistant cable insulating sheath manufactured by multi-crosslinking process and manufacturing method and application thereof

The invention discloses a halogen-free flame-retardant thin-walled oil-resistant cable insulating sheath manufactured by a multi-crosslinking process and a manufacturing method and application thereof. The halogen-free flame-retardant thin-walled oil-resistant cable insulating sheath comprises the following raw materials: an ethylene-vinyl acetate copolymer, rubber, a thermoplastic polyolefin elastomer, a halogen-free flame retardant, a phosphorus based flame retardant, a reinforcing filler, an inorganic functional filler, an organic functional masterbatch, a vulcanizing agent, a vulcanizationaccelerator, an anti-aging agent, a coupling agent, a macromolecular compatibilizer, a lubricant, an anti-oxidant, a nucleating agent, an antistatic agent and a color masterbatch. In the material preparing and cabling process, preparation and cabling of a preset-structured material are realized through physical and chemical crosslinking; manufacture of materials and cables, which have the properties of low smoke, no halo
