The invention relates to fireproof sealing systems based on molten adhesives, containing a) a molten adhesive; b) binders; c) substances forming a carbon structure in the event of a fire; d) flame-protecting agents; and e) a component which swells in the event of a fire; and a process for the flameproof sealing of objects or apertures by the application of such sealing systems.
Description
CA 02228479 1998-01-lS
Fire-retardant sealing system based on hotmelt adhesives and process ~or the flameproof sealing of articles or apertures The present invention relates to a fire-retardant sealing system based on hotmelt adhesives and a process for the flameproo~ sealing of articles or apertures by applying such a sealing system Known fire-retardant sealing systems are, for example, fireproof laminates. Fireproof laminates usually consist of a fireproof material which is laminated with a carrier web, for example a nonwoven glass fiber, textile fiber or carbon fiber fabric, and are used, for example, for the production of door seals, window seals or other seals. Furthermore, fireproof laminates are also employed between glass and frame in ~ireproo~ glazing and inside ~ireproof doors To permit fixing, some o~ the fireproo~ laminates are provided with an adhesive layer. In the absence of an adhesive layer, application can also be e~ected, ~or example, by screwing on or by means of nails.
However, the disadvantage of the fireproof laminates known to date is the method o~ application, since either the additional provision of an adhesive layer or the additional work o~ screwing on or nailing on i5 required. A further disadvantage is the loss of laminate resulting ~rom the exact adaptation of predetermined laminate sizes to the article to be sealed in each case.
It was accordingly the object of the present invention to provide a fire-retardant sealing system which can be installed, readily and without losses, in the article to be rendered fire-retardant.
Unexpectedly, it was possible to achieve this object by the combination of fireproof components with hotmelt adhesives.

The present invention accordingly relates to ~ire-retardant sealing systems based on hotmelt adhesives, which contain a) a hotmelt adhesive, b) binders, c) substances ~orming a carbon skeleton in the event o~ a fire, d) flameproo~ing agents and e) a component which is intumescent in the event o~ a ~ire.
The novel sealing systems are based on hotmelt adhesives. Suitable hotmelt adhesives are, ~or example, those based on synthetic rubbers, pre~erably based on so-called thermoplastic rubber grades, such as, ~or example, block copolymers o~ styrene and butadiene or isoprene or butyl rubber. Hotmelt adhesives based on low molecular weight polyethylenes (PE) and polyethylene waxes, those based on high molecular weight ethylene/vinyl acetate copolymers, those based on atactic polypropylene, those based on ethylene/acrylate copolymers, with or without a low content o~ carboxyl groups, those based on polyamides and polyaminoamides, those based on polyurethanes and those based on aliphatic or aromatic polyesters are also suitable.
These hotmelt adhesives may contain conventional additives, such as, ~or example, antioxidants, plasticizers, pigments ~or coloring, such as those ~or imparting whiteness, ~illers and the like.
According to the invention, binders, ~or example polymeric binders, or ~ibers are added to the hotmelt adhesive used ~or the preparation o~ the sealing system. Examples of polymeric binders are polyvinyl acetate, polyvinyl acrylate, polyvinyl chloride copolymers or polychloroprenes. Pre~erred ~ibers are mineral ~ibers Mineral ~ibers are CA 02228479 1998-01-1~
. ~
Wo 07/04037 PCT/EP96/03016 understood, depending on their starting materials, as glass, rock or slag ~ibers, as well as ceramic ~ibers.
The terms mineral wool, glass wool, rock wool and slag wool are also commonly used. Pre~erably used binders are ~ibers, and mixtures o~ dif~erent ~ibers may also be employed.
Furthermore, a substance ~orming a carbon skeleton or carbon crust in the event o~ a ~ire is added to the hotmelt adhesive. Suitable substances are, ~or example, thermosetting plastics, such as, for example, formaldehyde resins, urea resins, phenol resins, phenol/~ormaldehyde resins, polyacrylonitrile, polyimides, melamine resins, sugar, molasses, cellulose or derivatives thereo~. The resins used should pre~erably have a melting point between 100 and 200~C.
Phenol resins and phenol/~ormaldehyde resins prove to be particularly advantageous. During the heating in the event o~ a ~ire, these substances initially crosslink, the strong intermolecular bonds also being retained during the ~urther thermal load which leads to pyrolytic decomposition and ~inally to the ~ormation o~
a paracrystalline carbon skeleton (Chemie-Ing.-Tech. 41 No. 9/10 (1970), pages 659-669).
As a third component, a ~lameproofing agent is mixed with the hotmelt adhesive to render the latter ~lameproo~. Examples of suitable ~lameproo~ing agents are aluminum hydroxide, aluminum oxide trihydrate, magnesium hydroxide, calcium carbonate, boron compounds, ammonium sulfamate or urea. For example, oxides and carbonates o~ metals, such as, ~or example, bismuth, tin, iron, antimony or molybdenum oxides or bismuth carbonate, and other conventional flameproo~ing agents may ~urthermore be used.
A component which is intumescent in the event o~ a ~ire is also added. Suitable intumescent components are all components or substances which ~oam CA 02228479 1998-01-1~
wO 07/04037 PCT/EP96/03016 in the event of a fire and are present in solid form, for example as powder or granules. These are, for example, components based on expanded graphite, silicates, polyurethanes, nitrogen compounds or phosphorus compounds, as disclosed, for example, in EP-B-153 564 or EP-B-338 347. Expanded graphite or a component based on phosphorus compounds is preferably used.
The amounts of the individual components in the sealing systems according to the invention depend on the requirements which their properties have to meet and on the required behavior in the event of a fire, a high content of intumescent component having an advantageous effect on the fire behavior, a high content of binders having an advantageous effect on the flexibility and a high content o~ substances which ~orm a carbon skeleton in the event of a fire having an advantageous ef~ect on the strength of the sealing systems in the event of a fire.
The sealing systems according to the invention preferably contain a) 30 to 70~ by weight, particularly preferably 40 to 60% by weight, of hotmelt adhesive, b) 1 to 15~ by weight, particularly preferably 3 to 10~ by weight, of binder, c) 1 to 15~ by weight, particularly preferably 3 to 10~ by weight, of substances forming a carbon skeleton in the event of a fire, d) 1 to 25~ by weight, particularly preferably 1 to 15~ by weight, of ~lameproofing agents and e) 10 to 40~ by weight, particularly preferably 15 to 30~ by weight, of intumescent components.
The preparation of the sealing systems according to the invention is carried out by simply mixing together and melting together the individual components, for example in a heatable stirred vessel.
CA 02228479 1998-01-1~
-The melt thus obtained is then ~abricated in a tabletting or granulating apparatus. The melts are, for example, dripped onto a cooling belt or applied as a ~ilm to a cooling belt ~or solidi~ication and then cut. Heatable kneaders or extruders, downstream o~
which appropriate ~abrication means are connected, are pre~erably used.
The ~lameproo~ sealing o~ the articles or apertures to be protected is then preferably e~ected by means o~ apparatuses usually used for applying hotmelt adhesives, ~or example a so-called jet applicator or a hotmelt hand gun The granular or tablet-like sealing system is pre~erably lique~ied in a premelt container under atmospheric pressure at a temperature o~ between 100 and 200~C and then applied through the applicator nozzles. The application can be adjusted in a very exact and variable manner by means o~ the type and bore o~ the nozzle, the pressure o~ the ~ireproo~ laminate and the control o~ the nozzle ori~ice After cooling and solidi~ying, the sealing system adheres ~irmly, by means o~ the hotmelt adhesive present, to the article to be protected.
By means o~ the ~ire-retardant sealing system according to the invention, imparting ~lame-retardancy, ~or example, ~ireproo~ glazing, ~ireproo~ doors and other apertures to be sealed, ~or example, joints or cable ducts, is substantially facilitated, and ~urthermore there are no losses as in the adaptation o~
conventional sealing systems in laminate ~orm.
