Sheath is connected by multiple support columns, and outer jacket end is connect with sheath end part seal；
Outer jacket is made of Ceramic silicon rubber material, and multiple through-holes are formed on outer jacket, are filled with packet in through-hole
The material of the resin containing peek；
Outer jacket end is equipped with connecting hole, and connecting hole with the air accumulator for storing nitrogen or carbon dioxide for connecting.
Preferably, multiple through-holes are uniformly arranged along outer jacket surface.
Preferably, multiple support columns are uniformly arranged between outer jacket and sheath.
Preferably, support column is made of Ceramic silicon rubber material.
It preferably, further include multiple capsules, multiple capsules are fixed between outer jacket and sheath, filled with resistance in capsule
Fire agent.
Preferably, multiple capsules are located near multiple through-holes.
It preferably, further include multiple capsules, through-hole ecto-entad includes the first hole section and the second hole section, the first hole section and the
Two hole sections are connected, and the material comprising peek resin is filled in the first hole section, and capsule is filled in the second hole section, fill out in capsule
Filled with fire retardant.
Preferably, capsule is made of polytetrafluoroethylene material.
In the present invention, the fire-retardant electric-heating belt proposed, outer jacket is made of Ceramic silicon rubber material, because furthermore protecting
Layer reacts to form hard ceramic shell, to protect outer jacket internal structure, and on outer jacket when encountering open fire
Through-hole in be filled with the material comprising peek resin, material comprising peek resin, which meets open fire, to burn, once through-hole is burnt
It wears, the carbon dioxide or nitrogen between outer jacket and sheath will be leaked endlessly, the titanium dioxide leaked
Carbon or nitrogen are enclosed in around electric-heating belt, play fire-retardant effect.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of fire-retardant electric-heating belt proposed by the present invention；
Fig. 2 is a kind of side view of fire-retardant electric-heating belt proposed by the present invention.
Specific embodiment
As shown in Figs. 1-2, Fig. 1 is a kind of structural schematic diagram of fire-retardant electric-heating belt proposed by the present invention, and Fig. 2 is the present invention
A kind of side view of the fire-retardant electric-heating belt proposed.
Referring to Fig.1-2, a kind of fire-retardant electric-heating belt proposed by the present invention, including sheath 1, outer jacket 2 and multiple supports
Column 3；
1 section of sheath is rounded, and metallic conductor is located inside sheath 1, and outer jacket 2 is coated on sheath in a ring
Pre-determined distance between 2 outer wall of 1 outside sheath, 1 inner wall and outer jacket, outer jacket 2 and sheath 1 are connected by multiple support columns 3
It connects, multiple support columns 3 are uniformly distributed between outer jacket 2 and sheath 1, and outer jacket 2 and sheath 1 seal at both ends；
Outer jacket 2 is made of Ceramic silicon rubber material, and Ceramic silicon rubber material meets open fire and reacts to form heavily fortified point
Hard ceramic shell, ceramic shell can effectively separate open fire and sheath 1, thus play the role of fireproof, and
Pre-determined distance between outer jacket 2 and sheath 1 can play certain heat-blocking action；
Multiple through-holes 21 are formed on outer jacket 2, multiple through-holes 21 are uniformly distributed on 2 surface of outer jacket, fill out in through-hole 21
Filled with the material comprising peek resin, the material melting point comprising peek resin be greater than at more than 300 degrees Celsius, therefore when comprising
It when the material of peek resin meets open fire, will not be melted in the short time, after meeting open fire long period of time, include peek resin
Material can just be melted and be dropped down, and be connected to outside the gap between outer jacket 2 and sheath 1 and outer jacket 2；
2 both ends of outer jacket are respectively equipped with connecting hole 22, and connecting hole 22 is used for and the gas storage that stores nitrogen or carbon dioxide
Tank connection, or store non-combustible or not combustion-supporting air accumulator with other and connect, the gas in air accumulator passes through connecting hole 22
Gap between outer jacket 2 and sheath 1, but not leak out, once fire occurs, outer jacket 2 is met open fire and is formed
Hard ceramic shell, and the material chance open fire comprising peek resin in through-hole 21 is melted afterwards for a period of time and is dripped down
Come, the gas between outer jacket 2 and sheath 1 will be leaked endlessly, and the gas leaked is enclosed in electric companion
Around tropical, fire-retardant effect is played.
In the present embodiment, support column 3 is made of Ceramic silicon rubber material, and support column 3 can also harden shape after meeting high temperature
At hard ceramic shell, the relative position between sheath 1 and outer jacket 2 is kept not change, if using other
The material that high temperature easily melts is met, once support column 3 melts, outer jacket 2 will be resisted against on sheath 1, influenced gas and protected inside
It is flowed between layer 1 and outer jacket 2.
It further include multiple capsules in the present embodiment, multiple capsules are fixed between outer jacket 2 and sheath 1, fill out in capsule
Filled with fire retardant, fire retardant can be using materials such as antimony oxide, magnesium hydroxide, aluminium hydroxides；Further, through-hole 21 by
It outside to inside include the first hole section and the second hole section, the first hole section is connected with the second hole section, the material filling comprising peek resin
In the first hole section, capsule is filled in the second hole section, after material melts comprising peek resin in the first hole section, capsule
Meeting high temperature can also melt, and the fire retardant of capsule is scattered in through-hole 21 after fusing, and under the drive of gas, from through-hole 21
In trickle down and come out, and trickle down to the object around 2 surface of outer jacket and electric-heating belt, further function as flame retardant effect.
In the present embodiment, capsule is made of polytetrafluoroethylene material, the fusing point of polytetrafluoroethylene material be lower than comprising
The material of peek resin, after the material comprising peek resin melts, polytetrafluoroethylene material also has already passed through high-temperature heating one
Section time, polytetrafluoroethylene material can also melt quickly, unrestrained out convenient for the fire retardant of capsule.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
