Abstract
The utility model discloses a flame-retarding expansion sealing strip, which comprises a fireproof expansion layer and sealing layers which cover an upper surface and side surfaces of the fireproof expansion layer. The section of the fireproof expansion layer is of a dovetail structure, and the sealing layers are an integral structure. The flame-retarding expansion sealing strip disclosed by the utility model can expand uniformly when heated, thereby avoiding the phenomenon of poor sealing effect due to non-uniform expansion, and realizing fireproof and sealing functions effectively. In addition, the flame-retarding expansion sealing strip is nice in appearance, good in sealing effect, firm in fixation, and convenient and reliable in use, can save materials, and is mainly applied to 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.At present, the fire prevention expanding sealing strips that uses on the market is divided into two-layer, and superstructure is a sealant; Lower floor is fire-resistant expanding layer, two-layer between bonding forming, and then be cut into the strip structure of fixed width; Insecure between this weather strip is two-layer in use, come off easily, and when running into high temperature; After fire-resistant expanding layer expanded, the sealing effectiveness of sealant then can weaken.
The utility model content
Expand evenly when the technical problem that the utility model will solve provides a kind of high temperature, and be not easy when using to come off, the fire-retardant expanding sealing strips of good sealing effect.
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 covers fire-resistant expanding layer upper surface and side; The cross section that it is characterized in that said fire-resistant expanding layer is a swallowtail-shaped structure, and said sealant is structure as a whole.
The side of said fire-resistant expanding layer is a circular arc.
The soffit of said fire-resistant expanding layer is provided with the adhesive linkage that is used for fixing.
Fire-resistant expanding layer in the utility model is the refractory swelling material extrusion modling, and sealant is a PVC rubber mix material, can excision forming, and bonding between the two back is through pushing compound becoming one.
Adopt the beneficial effect that technique scheme produced to be: swallow-tail form or circular arc are arranged in the fire-resistant expanding layer cross section of the utility model, guarantee to be not easy in use to come off; Under high-temperature condition, because integral body is flat structure, integral body is heated evenly, and fire-resistant expanding layer is expanded evenly, does not influence the sealing effectiveness of sealant.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the cross-sectional view of the utility model;
Fig. 2 is the cross-sectional view of embodiment 2;
Wherein: 1, sealant; 2, fire-resistant expanding layer, 3, adhesive linkage.
The specific embodiment
Embodiment 1:
Can know according to accompanying drawing 1; The utility model is specifically related to a kind of fire-retardant expanding sealing strips; Comprise fire-resistant expanding layer 2 and the sealant 1 that covers fire-resistant expanding layer 2 upper surfaces and side; The cross section that it is characterized in that said fire-resistant expanding layer 2 is a swallowtail-shaped structure, and said sealant 1 is structure as a whole, and the soffit of said fire-resistant expanding layer 2 is provided with the adhesive linkage 3 that is used for fixing.
Embodiment 2:
The side of fire-resistant expanding layer 2 is a circular arc, and other structures are identical with embodiment 1.
The utility model owing to sealant 1 is outwards showed, therefore can be provided with multiple color, with eye-catching sign after stickup.
Except that the foregoing description,, be the scope of this patent protection if the cross section of fire-resistant expanding layer 2 is up big and down small structure.
Claims (3)
1. fire-retardant expanding sealing strips; Comprise fire-resistant expanding layer (2) and cover the sealant (1) of fire-resistant expanding layer (2) upper surface and side; The cross section that it is characterized in that said fire-resistant expanding layer (2) is a swallowtail-shaped structure, and said sealant (1) is structure as a whole.
2. a kind of fire-retardant expanding sealing strips according to claim 1, the side that it is characterized in that said fire-resistant expanding layer (2) is a circular arc.
3. a kind of fire-retardant expanding sealing strips according to claim 1 and 2 is characterized in that the soffit of said fire-resistant expanding layer (2) is provided with the adhesive linkage (3) that is used for fixing.
