Between, steel-tape armouring layer is wrapped in outside the wrapped separation layer of polyvinyl chloride, and calcium carbonate flame-retardant layer is arranged on steel-tape armouring layer and polychlorostyrene
Between ethene oversheath.
Further, the calcium carbonate flame-retardant layer is enclosed on the outer wall and polyvinyl chloride oversheath of steel-tape armouring layer in a tubular form
Between inwall.
Further, it is uniformly distributed to open up on the tube wall of the tubulose calcium carbonate flame-retardant layer and forms heat emission hole.
Further, the calcium carbonate flame-retardant layer is made up of the fire-retardant block of calcium carbonate, on the inwall of polyvinyl chloride oversheath
It is uniformly distributed shaping and is provided with fixed hole, the fire-retardant block plug dress of calcium carbonate is fixed on the fixed hole on polyvinyl chloride oversheath inwall
Interior, the inwall of polyvinyl chloride oversheath is close to the outer wall of steel-tape armouring layer.
Further, the fire-retardant block of the calcium carbonate is in cylindrical shape, and fixed hole is circular hole hole, and the fire-retardant block of calcium carbonate is straight
Plug is connect in fixed hole.
Further, the depth in the fixed hole is 1/3rd of polyvinyl chloride oversheath wall thickness.
The utility model has the advantages that：
A kind of flame retardant type band-armored of the utility model, is set between its steel-tape armouring layer and polyvinyl chloride oversheath
There is calcium carbonate flame-retardant layer, when fire occurs, high temperature can decompose calcium carbonate flame-retardant layer caused by cable fire, discharge titanium dioxide
Carbon gas, so as to weaken the air ambient of cable fire, help to prevent cable from firing by the carbon dioxide discharged
The continuation of burning, have and can be applied to the public arenas such as hotel, bank, hospital, factory and commercial residential building, can be hindered when fire occurs
Only cable to people because of the characteristics of damaging and hindering rescue action of burning.

Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described, in order to become apparent from geography
Solve the technological thought of the requires of the utility model protection.
A kind of flame retardant type band-armored of the utility model as shown in Figure 1-2, include cable core 1 successively from inside to outside, gather
The wrapped separation layer 4 of vinyl chloride insulation layer 2, glass fibre gasket for packing 3, polyvinyl chloride, steel-tape armouring layer 5, the and of calcium carbonate flame-retardant layer 6
Polyvinyl chloride oversheath 7, cable core 1 are wrapped in polyvinyl chloride insulation layer 2, glass fibre gasket for packing 3 be wrapped in polyvinyl chloride around
In bag separation layer 4 and it is filled between polyvinyl chloride insulation layer 2, steel-tape armouring layer 5 is wrapped in the wrapped separation layer 4 of polyvinyl chloride
Outside, calcium carbonate flame-retardant layer 6 is arranged between steel-tape armouring layer 5 and polyvinyl chloride oversheath 7.
