NOVELTY - A low-smoke halogen-free silane crosslinked flame-retardant cable material comprises 100 pts. wt. polyethylene resin, 25-28 pts. wt. dioctyl phthalate, 18-25 pts. wt. nickel-doped zinc aluminum layered double hydroxide, 5-10 pts. wt. magnesium hydroxide, 2-4.5 pts. wt. zinc borate, 3-6 pts. wt. nitrogen-doped titanium dioxide, 1-3.5 pts. wt. nano-montmorillonite, 10-16 pts. wt. calcium carbonate, 10-16 pts. wt. mica powder, 1.5-2.2 pts. wt. vinyltriacetoxysilane, 0.6-0.75 pt. wt. 1,1-di(tert-butylperoxy)cyclohexane, 1-1.5 pts. wt. catalyst, 2.5-3.5 pts. wt. stabilizer, 0.1-0.2 pt. wt. antioxidant, and 1.5-2.5 pts. wt. lubricant. USE - Low-smoke halogen-free silane crosslinked flame-retardant cable material. ADVANTAGE - The low-smoke halogen-free silane crosslinked flame-retardant cable material has excellent mechanical properties and thermal insulation performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of the low-smoke halogen-free silane crosslinked flame-retardant cable material, which involves: (1) uniformly mixing two-thirds of polyethylene resin, vinyltriacetoxysilane and 1,1-di(tert-butylperoxy)cyclohexane, and placing in an extruder for blending and extruding to prepare a blend (I); (2) evenly mixing the remaining amount of polyethylene resin and the catalyst, and placing in an extruder for blending and extruding to prepare a blend (II); (3) evenly mixing dioctyl phthalate, nickel-doped zinc aluminum layered double hydroxide, magnesium hydroxide, zinc borate, nitrogen doped graphene, nano-montmorillonite, calcium carbonate, mica powder, stabilizer, antioxidant and lubricant to obtain a blend (III); and (4) evenly mixing the blends (I)-(III) in a twin-screw mixer and then extruding and pelletizing.
