Property hydrogen halide, effectively improves the security of cable.
The present invention is achieved through the following technical solutions：
A kind of low smoke, zero halogen type cable insulation protective layer, is made up of the component of following mass fraction：
The fire retardant of cable insulation protective layer of the present invention uses red phosphorus, carbon black and molybdenum trioxide, with excellent resistance
Fuel efficiency fruit, wherein, molybdenum trioxide not only has excellent anti-flammability, also with the effect for suppressing smog generation, thus the present invention
Cable insulation protective layer will not produce smog and poisonous hydrogen halide in burning, effectively protect health and will not
Environment is polluted, the security of cable is improved.
Preferably, the low smoke, zero halogen type cable insulation protective layer, is made up of the component of following mass fraction：
Wherein, the antioxidant is (2,4 di-tert-butyl-phenyl) tris phosphite, and the lubricant is oleamide.
A kind of preparation method of low smoke, zero halogen type cable insulation protective layer, comprises the following steps：
1) according to mass fraction weigh hydrogenated styrene-butadiene block copolymer, ethylene propylene diene rubber, red phosphorus, carbon black,
Molybdenum trioxide, (2,4 di-tert-butyl-phenyl) tris phosphite and oleamide are standby；
2) by step 1) in each component mixed, then extruded by screw extruder, and in 75~85 DEG C of temperature
Carried out in water it is silane coupled, make each component be coupled after the insulating protective layer that is formed be coated on the cable that needs are processed.
The present invention compared with prior art, has the following advantages and advantages：
A kind of low smoke, zero halogen type cable insulation protective layer of the present invention, the fire retardant of cable insulation protective layer uses red
Phosphorus, carbon black and molybdenum trioxide, with excellent flame retardant effect, wherein, molybdenum trioxide not only has excellent anti-flammability, also has
Suppress the effect that smog is produced, thus cable insulation protective layer of the present invention will not produce smog and poisonous hydrogen halides in burning
Gas, effectively protects health and environment will not be polluted, and improves the security of cable.
