Abstract
The utility model discloses a flame-retarding expansion sealing strip which comprises a fireproof expansion layer and a sealing layer covered on the outer side of the fireproof expansion layer. The fireproof expansion layer is a hollow pipe, and the upper surface of the fireproof expansion layer is provided with a compression cavity with the same material as the sealing layer. The flame-retarding expansion sealing strip can be evenly expanded when heated, the phenomena that the sealing effect is poor due to unevenness of expansion are avoided, and the fireproof sealing function is effectively achieved. Besides, the flame-retarding expansion sealing strip is attractive, good in sealing effect, firm to fix and convenient and reliable to use, saves materials, and is mainly used for doors and windows of vehicles and ships.
Description
Technical field
The utility model relates to a kind of sealing device that is used for door, window sealing, especially a kind of can the fire-retardant expanding sealing strips of fireproof.
Background technology
Because people's fire safety consciousness increases, the consumption of labeled door and fire window is more and more.The a variety of fire proof seal bars that are used for doors and windows sealing are arranged in the market, but the Expansion sealing effect after meeting fire is all inequality.According to the fire prevention experience, when the fire proof seal bar when running into naked light, weather strip will have dilatancy; The thickness that expands should be 2 ~ 3 times of original thickness; Volume increases to original 15 ~ 20 times, only in this way could block the slit of labeled door effectively, prevents to scurry fire and leaks cigarette.
The patent No. is 97210272.8 to have announced a kind of fire prevention expanding sealing strips; Rectangle inner core and the fire-retardant overcoat of PVC that it is expanded by fire prevention are formed, and this solid weather strip is owing to being heated, and the heat transmission is inhomogeneous; It is even that it goes up expanding volume along its length, causes sealing effectiveness not good.
The utility model content
The technical problem that the utility model will solve provides that a kind of to be used for doors and windows sealing effective, and the effective fire-retardant expanding sealing strips of fireproof.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of fire-retardant expanding sealing strips; Comprise fire-resistant expanding layer; And the sealant that is wrapped in the said fire-resistant expanding layer outside, it is characterized in that said fire-resistant expanding layer is a hollow tube, the upper surface of fire-resistant expanding layer is provided with the compression chamber identical with the sealant material.When fire-resistant expanding layer ran into fire, its center was a hollow, and it is inner that high-temperature gas gets into hollow tube, and the temperature that integral body is received is even, then expanded evenly, the sealing effectiveness bad phenomenon that produces because of non-homogeneous expansion can not occur.
The internal cavities of said hollow tube is 1 or two parallel or vertical two.According to the size of weather strip, the internal cavities of fire-resistant expanding layer can be provided with a lot of forms, and a lot of arrangement modes so not only expand evenly, and saves material, attractive in appearance.
Said compression chamber is circular or semicircle.The material of compression chamber is identical with the material of sealant, is PVC rubber mix material, and soft, any surface finish is wear-resisting, is arranged to circle or semicircular structure, increases buffering, and sealing effectiveness is fine.
Bonding between said sealant and the fire-resistant expanding layer, the both side surface of sealant is symmetrical set the hook-type sawtooth.The sawtooth that is provided with in the utility model, its effect are to be fixed in weather strip on the door and window, and zigzag fashion is set to hook-type, increase the friction of the utility model and door and window, make fixing more firm.
Adopt the beneficial effect that technique scheme produced to be: (1) the utility model is a hollow tube in fire-resistant expanding layer; Make when being heated and evenly expand; Avoided realizing the fire proof seal function effectively, and saved material, attractive in appearance because of non-homogeneous expansion produces the bad phenomenon of sealing effectiveness; (2) compression chamber of the utility model is set to circle or semicircle, increases buffering, and sealing effectiveness is fine when using at ordinary times; (3) sawtooth is a hook-type in the utility model, and the friction of increase and door and window makes fixing more firm, easy to use, reliable.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1: can know according to accompanying drawing 1; The utility model is specifically related to a kind of fire-retardant expanding sealing strips, comprises fire-resistant expanding layer 1, and the sealant 2 that is wrapped in said fire-resistant expanding layer 1 outside; Said fire-resistant expanding layer 1 is a hollow tube; The upper surface of fire-resistant expanding layer 1 is provided with the compression chamber 3 identical with sealant 2 materials, and compression chamber 3 is a semicircular structure, and fire-resistant expanding layer 1 is a rectangle; The center has been arranged side by side two square cavity, has been symmetrical set three pairs of hook-type sawtooth 4 in the two sides of sealant 2.
Embodiment 2: can know that according to accompanying drawing 2 compression chamber 3 is a circular configuration, fire-resistant expanding layer 1 is a rectangle, and the center is provided with a square cavity, and other structures are identical with embodiment 1.
Embodiment 3: can know that according to accompanying drawing 3 fire-resistant expanding layer 1 is a rectangle, the center vertically is provided with two square cavity, has been symmetrical set four pairs of hook-type sawtooth 4 in the two sides of sealant 2, and other structures are identical with embodiment 2.
Embodiment 4: can know according to accompanying drawing 4; Fire-resistant expanding layer 1 is a polygonized structure, and the center is provided with a polygon cavity, and sealant 2 and fire-resistant expanding layer 1 are for being arranged above and below; Between paste through fluid sealant; Compression chamber 3 is the irregular quadrilateral structure, evenly arranges four hook-type sawtooth 4 on the right side of present embodiment, and 2 hook-type sawtooth are arranged in the left side.
In the utility model, fire-resistant expanding layer 1 is selected fire-resistant inflate compression material usually for use, its physical property be high temperature resistant, can not burn, meet fire and expand; Sealant 2 general PVC rubber mix material, the serviceability temperature scopes (40 ℃ ~+300 ℃) selected.
The utility model is to utilize coextrusion processes to produce the strip structure of continuous length, and the different length of intercepting is used to adapt under the various conditions as required.The utlity model has functions such as fire prevention, Smoke prevention, noise reduction, damping, sealing, be mainly used in fire-proof doors and windows, fire resisting damper, also can be applicable on car, ship, the aircraft.
