Independent claims are also included for the following: (1) Sealing profile of a fireproof and/or smoke-proof door; and (2) Method for the production of a sealing profile. Preferred Features: The sealing profile has a flat triangular shape.

Description

The Invention relates to a fire protection closure and / or smoke protection closure, with a plate-shaped closing element and a fixed with a building part anchored frame, in which the closing element is mounted rotatably, wherein in a gap region between an end face of the closing element and one opposite lying sealing surface of the frame on the frame along the Gap area extending sealing profile of an elastomeric material is arranged. Furthermore, the invention relates to a sealing profile for a fire door as described above or smoke door. Moreover, the invention relates a method of making one of an elastomeric material existing sealing profile of a fire door and / or Smoke-proof door, the production using an extruder takes place, from which the cross-sectional shape of the sealing profile corresponding die an endless strand of uncrosslinked material exits, which then crosslinked under the action of heat becomes.

Fire Barriers and / or smoke protection closures of the type mentioned are both as swing doors or doors with stop well known. Such doors need a Sealing function both wind and sound as well especially against smoke and fire passage. The sealing systems used for this purpose must be for a tolerance of the door leaf and the frame and the resulting tolerances in the gap region between the aforementioned Compensate components. Tolerances can thereby be conditioned by manufacture or occur during assembly or even caused by thermal expansions. Especially in case of fire become due to the large thermal load also appropriate caused large thermal retardations that are especially in faults of the door leaf but also the Frame itself can express. Preferably Therefore, a sealing system must have tolerances both within the plane of the door leaf as well as perpendicular to compensate.

From the DE 10 2004 051 307 A1 a fire protection of the type described above is known, in which both the sealing profile and the edge profile of the designed as a full-glass door leaf end element made of a silicone elastomer.

When disadvantageous occurs in the known fire protection in appearance, that during the opening and closing operation of the door leaf Relative displacements between the frame-side sealing profile and the frame itself occur. In extreme cases, it can by a particularly strong deformation or rejection of the sealing profile even come to that sealing profile with an anchoring profile partially or completely from the corresponding holding groove is pulled, which either a proper Closing and sealing impossible or impossible at least one subsequent closing process strong difficult or prevented.

From the DE 20 2006 017 815 U1 a floor seal of a smoke door is known, which is equipped with a concertina-like body to compensate for height tolerances between the lower end of the door panel and the floor can. In order to maintain a functional capability of the smoke protection seal over a long period of time and in particular to reduce the wear on the rubber-elastic seal due to movement, its surface is provided in a lower, contact-facing area with a coating having a significantly higher Shore hardness compared to the base material. The known coating is matched to the friction combination coating material - floor covering (tiles, PVC, carpet, wood, etc.).

task

Of the Invention is based on the object, a fire protection and / or to provide a smoke control certificate in spite of the material pairing for sealing profile and edge profile malfunctions as a result of undesired deformations or distortions the profiles or one of the two profiles is prevented. Furthermore to a corresponding sealing profile and a method for its Production to be proposed.

solution

outgoing from a fire protection and / or smoke protection certificate initially described type, this object is achieved according to the invention solved that one coming into contact with the edge profile Surface of the sealing profile and / or one with the sealing profile coming into contact surface of the edge profile with a Surface coating is / are provided that the sliding friction coefficient the respective surface compared with an uncoated one Condition reduced.

The solution according to the invention thus reduces the transverse forces produced during the closing or opening process and thus also the deformations or displacements of the relevant parts of the sealing profile or edge profile. The coating is firmly connected to the base material of the sealing profile and / or edge profile, so that a durable and throughout the life of the fire protection closure or Smoke protection functional solution is created.

According to one contains particularly preferred embodiment of the invention the surface coating in the liquid, not cured state cyclohexane, xylene, ethanol, Ethylbenzene, ethyl acetate, an acrylic polymer, 2,5-furandione and propan-2-ol.

Out It is known in the art to have such a composition to be used as a primer. Such a primer serves as a bonding agent between different material surfaces, eg. B. between the Surfaces of silicone elastomers and the surfaces of adhesive tapes based on acrylate adhesives. A Composition of the invention proposed Art is for example from the company 3M (Switzerland) AG in Rüschlikon manufactured under the name "Primer 94". surprisingly Way, it has now been found that so far only primer used as a primer when applied to a surface an existing elastomeric sealing profile or a Edge profile which cooperates with an elastomeric sealing profile of the friction coefficient is significantly reduced. For sealing systems Smoke protection and / or fire protection The type described above leads to this reduction in friction an increase in functional reliability and a reliable Avoidance of unintentional, lateral force induced profile shifts or distortions.

Also if already with an arrangement of the coating on only one the two relatively moving profiles an improvement the sliding process is observed, should preferably in the Sliding operation with each other in contact surfaces both profiles with such a surface coating be provided. Preferably, further, both the sealing profile as well as the edge profile of a silicone-containing elastomeric material.

The Invention further ausgestaltend is provided that the sealing profile in cross-section is flat triangular, with a baseline of the isosceles triangle parallel to the sealing surface the frame extends, wherein in the interior of the sealing profile extending over its entire length cavity located. Preferably, the triangle is in the region of its tip with the largest possible radius of curvature rounded. In the open position of the closing element is the area of the apex of the triangle opposite to something compressed form in the closed position, in the closed position, a secure contact between the to reach opposite surfaces. The elevation depends on the expected gap tolerances, where to achieve a sufficient sealing effect a minimum bias also should remain in the closed state of about 1 mm. To tolerances balancing in the other direction is a sufficient possibility provide for deflection of the sealing profile in the closed state, in which case the triangle is pressed into a flatter shape in this case becomes.

Around a satisfactory dimensional stability of the sealing profile can ensure starting from the top of the Triangles extend two support legs inside the triangle, which together with the baseline another, preferably isosceles, Forming a triangle, whereby the cavity is divided into three chambers becomes.

The The aforementioned support legs then develop a particularly good effectiveness in extending beyond the baseline are and with their respective end on a support surface support the frame, wherein the support surface from a recessed groove portion of a connected to the frame Holding profile for the sealing profile is formed.

If the sealing profile on two edges, which in one direction spaced apart perpendicular to the plane of the closure element are anchored to the frame, the danger is that the sealing profile by the transverse forces occurring during the closing process one side is pulled out of its holder, especially low. The sealing profile should be at the edges with each an undercut Klemmwulst in a customized undercut Engage clamping groove in the frame. Such a positive Connection between sealing profile or its clamping beads and the frame or an attached holding profile facilitates In addition, the assembly, which takes place without adhesive, as well as a possible disassembly when replacing the sealing profile.

The The object of the invention is further solved by a sealing profile of a fire door and / or Smoke door, consisting of an elastomeric material having a curved shape in cross-section and a contact surface, wherein the sealing profile according to the invention is characterized in that the contact surface with a sliding friction coefficient in comparison with the elastomeric material reducing surface coating cyclohexane, xylene, ethanol, ethylbenzene, Ethyl acetate, an acrylic polymer, 2,5-furandione and propan-2-ol.

Starting from a method of the type mentioned above, the underlying object is also achieved in that before the crosslinking of the elastomeric material on surface regions of the strand, a layer of a Fließfähi material containing cyclohexane, xylene, ethanol, ethylbenzene, ethyl acetate, an acrylic polymer, 2,5-furandione and propan-2-ol is applied and then the elastomeric material is crosslinked together with the layer-forming material under heat, causing the strand a solid surface protective layer is produced.

The common networking of the base material with the coating material results in an intimate bond between the coating and the basic material. In particular, this makes it possible that the surface coating with the arranged underneath Substrate in the form of the elastomeric material over the phase boundary and thus covalent bonds is bound to the elastomeric material of the sealing profile.

The inventive method further ausgestaltend It is suggested that the elastomeric material be one with peroxide staggered silicone rubber is and that the crosslinking by radical release takes place under the action of heat.

According to one Embodiment of the method according to the invention the application of the material forming the layer takes place by brushing, -rolling, -streichen or in the manner of a spray painting each using a preferably stationary applicator.

If the endless strand after applying the layer forming Material is passed through a hot air duct and preferably on a conveyor belt becomes simultaneously with the vulcanization of the elastomeric material also for a rapid evaporation of the solvent in which the coating forming material, so that a uniform thin surface coating in the manner of a lacquer layer on the profile surface.

After all is still provided according to the invention that the sealing profile is tempered after crosslinking, in particular for a Period between two hours and six hours in a convection oven a temperature between 180 ° C and 220 ° C, preferably of 200 ° C, is exposed. Become through this temper Remains and degradation products of crosslinking chemicals (peroxides) removed. In this way it also prevents the degradation products bloom during later use, which would result in unpleasant optical properties. In addition, disappears by the tempering and the unpleasant smell of the peroxide. The already cross - linked material before the annealing Surface coating is opposite to the Tempering process prevailing temperatures stable, but points afterwards a pale yellowish discoloration, the usability the coated sealing profile but impaired in any way.

embodiment

The invention will be explained in more detail below with reference to an exemplary embodiment of a sealing profile and an edge profile coming into contact with it with reference to the accompanying drawing:
A not altogether shown, in its basic structure known Rauchschutzabschluss consists of a per se known frame, not shown, and a rotatably mounted therein and only schematically shown end element 1 in the form of a full glass door leaf. In known manner, the door leaf consists of a plurality of individual panes with interposed layers of transparent fire protection gel. From the frame is only designed as an aluminum extruded profile 2 for a silicone elastomer elastomer sealing profile 3 shown. The sealing profile 3 has in cross-section the shape of a flat triangle, in the region of its tip 4 is rounded. The triangle is formed by two legs of equal length 5 and a base line connecting its opposite ends 6 , Starting from the top 4 furthermore, two extend inside the sealing profile 3 arranged support legs 7 that deals with free end sections 8th over the baseline 6 extend beyond. The interior of the gasket profile 3 is through the two support legs 7 in three in the longitudinal direction of the sealing profile 3 extending chambers 9 . 10 . 11 divided.

The holding profile firmly connected to the frame 2 has at its opposite edges in each case an undercut clamping groove 12 on, in which the sealing profile 3 with equally adapted undercut shaped Klemmwülsten 13 intervenes. The clamping beads 13 extend over the entire length of the sealing profile 3 and are each near the associated longitudinal edges. To the clamping beads 13 Transverse to its longitudinal direction to provide increased elasticity and thus facilitate the assembly process is located inside each Klemmwulstes 13 a cavity in the form of a chamber 14 , edge strips 15 each close to the outside to the clamping beads 13 and ensure an aesthetically pleasing gentle outlet of the sealing profile 3 into the surface of the retaining profile 2 ,

Between the clamping grooves 12 of the holding profile 2 there is another groove area 16 extending over the entire middle section of the retaining profile 2 extends. In the groove area 16 is a fire protection strip 17 inserted, which consists in known manner from heat swell material. On one the final element 1 facing surface 18 the fire protection strip 17 support the support legs 8th of the sealing profile 3 with slight deflection of herself to the outside.

The final element 1 is on one of the sealing surface of the frame facing end face 19 with an edge profile made of a transparent silicone elastomer 20 Mistake. The edge profile 20 has a U-shape and extends around the edges to be protected 21 of the glass pane package up to edge areas of viewing surfaces 22 of the conclusion element 1 , One of the frame facing front contact surface 24 of the edge profile 20 is slightly arched to the closing process of the closing element 1 a sliding of the contact surfaces 24 of the edge profile 20 on the one hand and the contact surface 25 of the sealing profile 3 on the other hand, in a geometrical way.

The drawing figure shows the two profiles 3 and 20 in an undeformed position in which the furthest points of the profile cross sections just touching each other. In practice, an installation of the two profiles 3 and 20 be done so that in a closed position of the closing element 1 the two profiles 3 and 20 with a certain voltage applied to each other, so that the sealing profile 3 deformed a few millimeters, but at least one millimeter towards the frame. In this way, sufficient preload and thus sealing effect in the area of the touching profiles 3 and 20 be achieved.

To the sliding of the two profiles 3 and 20 To facilitate is on the one hand, the entire the final element 1 facing contact surface 25 of the sealing profile 3 (starting at the edge strip 15 along the thighs 5 to the opposite edge strip 15 ) with a surface coating 27 which significantly reduces the coefficient of friction with the silicone elastomer base material. On the other hand, the entire slightly curved contact surface 24 of the edge profile 20 with such a surface coating 26 Mistake. In the drawing are the surface coatings 26 . 27 by an increased line width in the area of the respective contact surfaces 25 and 24 illustrated.

The production of the sealing profile 3 is briefly explained below. The production of the edge profile 20 can be done in an analogous manner.

The sealing profile 3 is made of a special fire-resistant and in case of fire ceramizing silicone rubber compound. For this purpose, the raw rubber mixture is extruded through a die and thus brought into the profiled shape shown in the drawing. Immediately after leaving the die, the still uncrosslinked sealing profile becomes 3 at its contact surface 25 coated with a paint solution by brush or spray painting. In which the later coating 27 forming material is the product "primer 94 " the company 3M (Switzerland) AG in Rüschlikon / Switzerland. The above-mentioned primer contains cyclohexane, xylene, ethanol, ethylbenzene, ethyl acetate, an acrylic polymer, 2,5-furandione and propan-2-ol, and has a solid content of about 6 at a liquid consistency at room temperature (viscosity between 30 and 40 cp) %.

After application of the coating material, the sealing profile runs 3 via a conveyor belt through a hot air duct. At the high temperatures prevailing there, the peroxide mixed in the silicone materials decomposes and forms radicals which cause the three-dimensional crosslinking of the polymer chains of the rubber mixture (vulcanization). In the course of this reaction, the thermoplastic raw mixture is used to create a material with rubber-elastic properties. As a side effect, the hot air ensures rapid evaporation of the solvent from the applied paint solution, so that forms a uniform thin paint layer on the profile surface.

in the Following the painting and vulcanization are the profiles in a separate step for four hours 200 ° C in a convection oven annealed by residues and degradation products of the crosslinking chemicals (peroxides). In this way prevents the degradation products during the later Use bloom and in addition the unpleasant disappears Smell of peroxide. The lacquer layer is opposite this Tempering process stable, but then shows pale yellowish discoloration on.

The drawing shows in horizontal section extending in the vertical direction gap region between the end element 1 and the frame not shown in full with the retaining profile attached thereto 2 , An identical design of the sealing system will usually be chosen in the upper horizontally extending gap area. Also in the area of the soil, it is basically possible, but not usual, to use such a sealing system. In principle, the use of the sealing system according to the invention in the gap region on the hinge side is also conceivable.
