The invention discloses a heatproof
corrosion-resistant cable material for
urban rail transport and a preparation method thereof. The heatproof
corrosion-resistant cable material is prepared from the following raw materials, by weight, 38-46 parts of teflon, 24-33 parts of a
liquid crystal polymer, 16-22 parts of polyarylsulfone, 10-15 parts of a nano-
zeolite molecular sieve, 6-12 parts of hexaphenoxy cyclotriphosphazene, 5-10 parts of
diethylene glycol dibenzoate, 3-6 parts of
microcrystalline wax, 8-16 parts of hollow glass microspheres, 14-18 parts of a composite
flame retardant, 4-9 parts of
melamine cyanurate, 2-3 parts of tri(
mercaptoacetic acid n-butyl ester)
antimony, 2-3 parts of 2-
octyldodecanol, 10-15 parts of
diallyl phthalate, 2-3 parts of Stearoylbenzoylmethane and 1-2 parts of 6-ethoxy-2,2,4-trimethyl-1,2-dihydro-
quinoline. The cable material has good
heat resistance, and the
heat resistance grade reaches 160 DEG C. In addition, the cable material has excellent
corrosion resistance, is especially resistant to corrosive mediums such as acid, alkali, salt, oil and the like, has good
wear resistance, weather
ageing resistance,
flame resistance and the like, and can completely meet requirements of performance when used under conditions of high-temperature corrosive mediums.
