Description
Technical field
The utility model relates to a kind of insulating cord, especially a kind of fire retardant insulating rope.
Background technique
Polyimide fiber is a kind of high-performance fiber, and limit oxygen index > 38% can be long at -260 DEG C to 260 DEG C
Phase uses, and 567 DEG C of thermal decomposition temperature；Char length is lower than 10mm, no yin when fabric vertical combustion made of polyimide fiber
Fire after flame time；It is widely used in flame protection field.Ultra high molecular weight polyethylene fiber has high intensity, high-modulus, light
The characteristics of, breaking strength is greater than 30cN/dtex, and modulus is greater than 1300 cN/dtex, and density is only 0.97g/m3, is production rope
The excellent material of rope.
Common rope has the function of single mostly at present, as silk rope has good insulation effect in dry conditions
Fruit, but the reduction of its insulation performance is larger in humid conditions；Ultra-high molecular weight polyethylene rope intensity with higher and relatively light
Weight, but its limit oxygen index is low, is easy burning and can not use in the high temperature environment；Aramid fiber rope has good resistance
Fuel efficiency fruit, but it is not sun-resistant, is easy discoloration and strength retrogression under sunlight irradiation, is unable to satisfy long-time service.
