Embodiment
The utility model embodiment discloses a kind of flexible fire-proof cable, flexible not and the problem such as fire-proof and thermal-insulation weak effect effectively to solve fireproof cable.
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-Fig. 2, the structural representation with the flexible fire-proof cable of individual cable body that Fig. 1 provides for the utility model embodiment; The structural representation with the flexible fire-proof cable of multiple cable body that Fig. 2 provides for the utility model embodiment.
In one embodiment, present embodiments provide a kind of flexible fire-proof cable, this flexible fire-proof cable comprises cable body 1, fireprotection layer 2, first fixed bed 3, thermal insulation layer 4 and the second fixed bed 5.It should be noted that herein, cable body 1 is electric conductor, it can be single electric conductor, also can be that multiply electric conductor is stranded, in order to improve flexibility and the electric conductivity of flexible fire-proof cable, preferred cable body 1 is that stranded copper wire is stranded, and in order to ensure the softness of copper wire, the diameter of copper wire can be made to be not more than 0.4 millimeter.Wherein fireprotection layer 2 is arranged on the outside of cable body 1, plays a kind of fireproof effect.Thermal insulation layer 4 is arranged between fireprotection layer 2 and cable body 1, and thermal insulation layer 2 enters into cable body 1 place for stoping high temperature, and cable body 1 produces the electric conductivity that high temperature can reduce cable body 1 greatly.First fixed bed 3 is wrapped in the outside of fireprotection layer 2, and the second fixed bed 5 is arranged between thermal insulation layer 4 and fireprotection layer 2.
Thermal insulation layer 4 and fireprotection layer 2 are Ceramic silicon rubber layer, and Ceramic silicon rubber is a kind of after the ablation of thermal-flame, generate a kind of hard housing, and this housing can be fire-resistant as pottery, thus can play fireproof effect.And because Ceramic silicon rubber is generally made up of silicon rubber base-material, mineral dust filler and other powder preparation, so Ceramic silicon rubber is not before becoming pottery, flexibility is good especially, heat-proof quality is also relatively good, so the thermal insulation layer 4 being positioned at fireprotection layer 2 can play effective effect of heat insulation.It should be noted that herein, because when Ceramic silicon rubber is thermal-flame, mainly form high temperature housing to the inside gradually from outside, and because form the finite thickness of housing, so should control the thickness of fireprotection layer well, and the distance between fireprotection layer 2 and thermal insulation layer 4, in order to avoid thermal insulation layer 4 also forms pottery with fireprotection layer 2, and the second fixed bed 5 between thermal insulation layer 4 and fireprotection layer 2 also can prevent the Ceramic silicon rubber of fireprotection layer 2 and the Ceramic silicon rubber of thermal insulation layer 4 from forming one pottery.Because the housing that the Ceramic silicon rubber of fireprotection layer 2 is formed is very thin, fragility is large, but scene of fire often has object and caves in and subside, so when being easy to cause ceramic shell that larger shock occurs, and housing fragility is large easily broken, now this layer of Ceramic silicon rubber just can not protect inside cable body 1 again, because the thermal insulation layer be now positioned at inside fireprotection layer 2 is also Ceramic silicon rubber, when after the ceramic shell fragmentation that the fireprotection layer 2 in outside is formed, now thermal-flame can contact the Ceramic silicon rubber of thermal insulation layer 4, make thermal insulation layer 4 can form new ceramic shell.So cable body 1 can be protected further, improve the fire insulation performance of flexible fire-proof cable.
But Ceramic silicon rubber pull resistance is poor especially, and easily cause the structural instability of Ceramic silicon rubber because of discontinuity, if destructurized, the phase is easy to cause and cannot forms compact texture after a procedure.Wherein the first fixed bed 3 and the second fixed bed 5 are for the protection of good Ceramic silicon rubber, change to prevent the structure of Ceramic silicon rubber.First fixed bed 3 and second day fixed bed 5 can be glass belt; because glass fibre belt has heat-resisting quantity and high strength; be wrapped in the outside of Ceramic silicon rubber; can effectively before Ceramic silicon rubber forms ceramic shell; effectively can protect pottery, cause destructurized to prevent Ceramic silicon rubber because external force exists.
General in the later stage of breaking out of fire, fire-fighting most probable uses liquid water to put flame out by water, and now cable body periphery probably exists and a large amount of dissolved in the water of ashes, has stronger conductivity, preferably between thermal insulation layer 4 and cable body 1, arranges insulating barrier 6.Insulating barrier 6 still may not spread the flame gone out completely and be burnt; thus cannot better protect cable body 1; preferably between insulating barrier 6 and cable body 1 at increase mica belt 7; mica tape has higher insulation property and flame resistance energy, and then can strengthen insulation property and the fire resistance of cable body 1 further.
It should be noted that, this flexible fire-proof cable only can have a cable body 1 herein, also can have multiple cable body 1.And when there is multiple cable body 1, each cable body 1 can be made to include all separately one deck thermal insulation layer 4, and be filled with filler between different thermal insulation layers 4, wherein filler has the movement preventing cable body 1, and generally also has heat insulation effect.Within thermal insulation layer, comprise thermal insulation layer form a new monomer, but after outermost layer destroys, new monomer, independently can exist again, but thermal insulation layer 4 can have fireproof function, and then continues the cable body 1 that protection is positioned at thermal insulation layer 4 inside.
Consider when non-breaking out of fire, flexible fire-proof cable should have can the sheath of water proof and dust proof and anticollision, to protect Ceramic silicon rubber.When considering breaking out of fire, sheath can be met fire and burn, so preferably make sheath be low-smoke halogen-free flame-retardant sheath.Low-smoke halogen-free flame-retardant sheath, when breaking out of fire is burnt, can not discharge dense smoke and toxic gas, and also have certain anti-flammability, plays preliminary fireproof function.
In this specification, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
