Although above-mentioned positive pressure air respirator strap is with stronger structural strength and stability, although to a certain degree
On alleviate the equipment weight that fireman bears, and be prevented from affecting the oxygen supply of fireman because gas cylinder falls in the case of room temperature
Breathing.But, when for the condition of a fire, more serious, brace is scorched by naked light, Fypro is easily blown, and then causes gas cylinder to fall
Fall, be unfavorable for that fireman persistently puts out a fire the disaster relief.
Utility model content
For the above-mentioned problems in the prior art, now aiming to provide a kind of prevents from being scorched blow high-strength by naked light
Spend fire-retardant brace.
Concrete technical scheme is as follows：
A kind of high-strength anti-flaming brace, has the feature that, including：The cortex of sandwich layer and cladding sandwich layer；Wherein, sandwich layer
Comprising some p-aramid fiber warps being arranged in rows, cortex is by some meta-aramid warps and a snakelike roundabout meta
Aramid fiber parallel intersects braiding.
A kind of above-mentioned high-strength anti-flaming brace, wherein, meta-aramid warp and meta-aramid parallel are by between some
Position aramid fiber long filament is closed and is twisted type.

And, the diameter with diameter greater than p-aramid fiber warp of meta-aramid warp.
A kind of above-mentioned high-strength anti-flaming brace, wherein, the diameter of a diameter of p-aramid fiber warp of meta-aramid warp
1.5 times to 3 times.
A kind of above-mentioned high-strength anti-flaming brace, wherein, in the core, one is arranged at interval of three p-aramid fiber warps
Connection warp；Connection warp is closed by meta-aramid fibers long filament and/or polyarylate fiber long filament and is twisted type, also, connection warp
Intersect braiding with meta-aramid parallel.
A kind of above-mentioned high-strength anti-flaming brace, wherein, the diameter of connection warp is less than the diameter of p-aramid fiber warp.
A kind of above-mentioned high-strength anti-flaming brace, wherein, the thickness of sandwich layer is 0.1 millimeter to 0.5 millimeter；The thickness of cortex
For 0.2 millimeter to 0.5 millimeter.
The good effect of above-mentioned technical proposal is：
In above-mentioned high-strength anti-flaming brace, sandwich layer is made using the p-aramid fiber warp of high intensity, cortex is by resistance of preventing fires
The meta-aramid warp of combustion better performances and the braiding that intersects of meta-aramid parallel are made, and the brace of this kind of structure is running into high temperature
Or naked light is when scorching, meta-aramid warp and meta-aramid parallel expanded by heating, and fine and close carbonization is formed in the outside of sandwich layer
Layer, it is to avoid blow the sandwich layer of high intensity, and then can prevent the weight that fireman bears from falling.
