Embodiment
Embodiment one：
Reference picture 1, a kind of elevator cable, including it is coated with internal layer flameproof fabric with cable core 8 rindy, the outside of cable core 8
7, the outside of internal layer flameproof fabric 7 is outer layer flameproof fabric 5, and refractory material 6 is filled between internal layer flameproof fabric 7 and outer layer flameproof fabric 5,
The outside of outer layer flameproof fabric 5 is coated with inner protective layer 4, and the outside of inner protective layer 4 is coated with fire extinguishing layer 3, and the inside of fire extinguishing layer 3 is filled
There is extinguishing chemical 9, the outside of fire extinguishing layer 3 is coated with high-temperature-resistant layer 2, and the outside of high-temperature-resistant layer 2 is external protection 1.
In the present embodiment, cable core 8 carries plastic peel, in two layers of flameproof fabric of outside cladding of cable core 8 --- internal layer fire prevention
Cloth 7 and outer layer flameproof fabric 5, two layers of flameproof fabric are silicon titanium flameproof fabric, leave space between two layers of flameproof fabric, are filled out in the space
Filled with magnesium oxide powder.Using common, cable protection material --- i.e. polyvinyl chloride is made internal layer protective layer.Fire extinguishing layer 3 uses
Be rubber layer, offer multiple cavitys in the inside of fire extinguishing layer 3, cavity is evenly distributed on inside fire extinguishing layer 3, is filled out in cavity
Filled with powder extinguishing agent 9.The mica tape that heat-resistant layer uses, mica tape are wrapped around in the outside of fire extinguishing layer 3, mica tape here
For synthetic mica tape.External protection 1 and the pvc material used.
The cable is during use, and when there is the condition of a fire, external protection 1 is burnt, and high-temperature-resistant layer 2 exposes immediately
Come, synthetic mica tape temperature classification is high, can reach A levels fire resisting level（950-1000℃）, synthetic mica tape is difficult to when being burnt
Melt, preferable protection can be formed to the structure sheaf of inner side.Synthetic mica tape can tackle the in general condition of a fire.
When the intensity of a fire is larger, synthetic mica tape can be burned out at a high temperature of more than 1000 DEG C.When high-temperature-resistant layer 2 is burned out
When, 9 layers of extinguishing chemical is exposed, and under the calcination of raging fire, for rubber by scorification, its surface produces cut, and the dry powder in cavity goes out
Fiery agent 9 sprays immediately, and powder extinguishing agent 9 covers flare, by the spark extinguishing of part, so as to contain the sprawling of the intensity of a fire, containment
The intensity of a fire increases.
If the intensity of a fire is too violent, the powder extinguishing agent 9 that fire extinguishing layer 3 stores fails to stop the sprawling of the intensity of a fire, in big fire
Under long-time calcination, fire extinguishing layer 3 is burned out.After fire extinguishing layer 3 is burned out, inner protective layer 4 is also followed by burned out.
After inner protective layer 4 is burned out, outer layer flameproof fabric 5 is exposed.Because outer layer flameproof fabric 5 is using the fire prevention of silicon titanium
Cloth.Silicon titanium flameproof fabric is a kind of high-temperature-resistant inorganic fibre, and its silica (SiO2) content is higher than 96%, and softening point is close to 1700
DEG C, can be long-term use of at 900 DEG C, it can be worked under the conditions of 1450 DEG C 10 minutes, work under the conditions of 1600 DEG C 15 seconds and still protect
Hold serviceable condition.Therefore, outer layer flameproof fabric 5 can be effectively protected after inner protective layer 4 is burned out to the structure sheaf on the inside of it.
If temperature caused by flare is more than 1450 DEG C, after few minutes, outer layer flameproof fabric 5 will be burned out, outer layer fire prevention
After cloth 5 is burned out, magnesium oxide powder is exposed.Magnesia belongs to binder materials, and its fusing point is 2852 DEG C, boiling point 3600
℃.Magnesia has extremely fireproof insulating properties.It can be changed into crystal through 1000 DEG C of high temperature above calcinations, rise to 1500-2000
DEG C then into dead roasting magnesia or sintered magnesia.After outer layer flameproof fabric 5 is burned out, magnesium oxide powder can effectively protect it
The structure sheaf of inner side.
This kind of elevator cable integrates multi-layer fireproofing structure, and each fireprotection layer corresponds to different high temperature ranges, and multilayer is prevented
Fire bed cooperates, and can effectively contain or even eliminate the intensity of a fire, so as to form strength protection to cable.This kind of cable fire-proof performance
It is very excellent, it is suitably applied the higher ranked communal facility of the fire-fightings such as elevator.
Embodiment two：
The present embodiment is that the material of inner protective layer 4 and external protection 1 is different from the difference of embodiment one.
Inner protective layer 4 and external protection 1 are made of fire proofing in the present embodiment, so as to further enhancing cable
Overall fire protecting performance.
Described above is only preferred embodiment of the present utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
