Description

Dämmschichtbildende Brandschutzfarben sind bekannt. Sie werden auf Stahl-, Beton- und Holzkonstruktionsteile wie Anstriche aufgetragen und bilden bei Feuereinwirkung eine porös aufgeblähte, wärmedämmende Schicht, die die Aufheizung des darunterlegenden Materials verzögert, so daß Stahl- und Betonteile ihre Festigkeit im Brandfall erst später verlieren als ungeschützte Teile, und bei Holz die Entflammung verzögert wird.Fire protection paints that form intumescent layers are known. They are used on steel, concrete and wooden structural parts Applied like paints and when exposed to fire form a porous, inflated, heat-insulating layer Layer that delays the heating of the underlying material, so that steel and concrete parts In the event of fire, they lose their strength later than unprotected parts, and in the case of wood, they do not catch fire is delayed.

Diese Farben eignen sich aber nur zum Schutz von flächigen Gebilden. Für die feuerhemmende Absperrung von Fugen, beispielsweise Dehnfugen in Decken, oder für die Sicherung von Durchbrüchen oder Hohlräumen sind sie von ihrer Natur her ungeeignet.However, these colors are only suitable for protecting flat structures. For the fire-retardant barrier of joints, for example expansion joints in ceilings, or for securing openings or cavities they are unsuitable by their nature.

Für diese Zwecke dienen bisher verschiedene Systeme, beispielsweise Glasfaserlaminate, Kombinationen von Glasfasern oder geschäumten Kunststoffgranulaten, die mit Butylkautschukstreifen verbunden werden (GB-PS 1080170), Dichtungsmassen aus Umsetzungsprodukten von Schwefel mit Diphenyldithiophosphat und Styrol (FR-PS 1 502687) und vulkanisierte Silicon-Elastomere (JA-PS 094385).Various systems, for example fiberglass laminates, combinations have previously been used for this purpose of glass fibers or foamed plastic granules, which are connected with butyl rubber strips (GB-PS 1080170), sealants from Reaction products of sulfur with diphenyldithiophosphate and styrene (FR-PS 1 502687) and vulcanized Silicone elastomers (JA-PS 094385).

Zum Teil können diese Massen nur zum Abdichten von Fugen dienen, nicht aber zur Sicherung größerer Hohlräume. Gemeinsam ist ihnen, daß sie zwar schwer- oder nichtentflammbar sind, daß sie aber keine Dämmschichten bilden und bei Feuereinwirkung verspröden und die Haftung verlieren, so daß kein sicherer Abschluß mehr gewährleistet ist.In some cases, these compounds can only be used to seal joints, but not to secure larger ones Cavities. What they have in common is that they are flame-retardant or non-inflammable, but that they are do not form insulating layers and become brittle when exposed to fire and lose adhesion, so that a secure conclusion is no longer guaranteed.

Durch die vorliegende Erfindung wird nun eine dämmschichtbildende Dichtungsmasse geschaffen, die auch über lange Zeit nicht versprödet, und die Fugen u. dgl. im Brandfall für längere Zeit feuer- und rauchdicht absperrt.The present invention now creates an intumescent sealant, which does not become brittle over a long period of time, and the joints and the like for a long period of time in the event of a fire shut off smoke-tight.

Erfindungsgegenstand ist eine feuerhemmende Dichtungsmasse nach den Ansprüchen.The subject of the invention is a fire-retardant sealant according to the claims.

Die Stabilisatoren für das Polymerisatgemisch sind insbesondere organische Zinnverbindungen. Als Dämmschichtbildner enthält die Dichtungsmasse für diesen Zweck bekannte Stoffe, insbesondere Ammoniumpolyphosphat, Melamin, Pentaerythrit und Stärke. Daneben kann die Masse zur Einstellung der Verarbeitbarkeit und der Standfestigkeit anorganische Füllstoffe wie Calciumcarbonat, Bariumsulfat und Glas- oder Mineralfasern enthalten.The stabilizers for the polymer mixture are, in particular, organic tin compounds. as The sealant contains substances known for this purpose, especially ammonium polyphosphate, Melamine, pentaerythritol and starch. In addition, the composition can be inorganic to adjust the processability and stability Contain fillers such as calcium carbonate, barium sulfate and glass or mineral fibers.

Es ist zwar bekannt, Vinylchloridpolymerisate und Weichmacher als Bindemittel für die Herstellung von Kitten oder Dichtungsmassen einzusetzen, und daß derartige chlorhaltige Polymerisate schwer brennbar sind. Diese thermoplastischen Bindemittel schmelzen jedoch bei Temperaturen, wie sie im Brandfalle auftreten. Zum Beispiel bei Temperaturen ab etwa 130° C laufen desh&lb damit ausgefüllte Fugen aus. Der Fachmann hätte annehmen müssen, daß derartige Kitte und Dichtungsmassen auch dann im Brandfalle auslaufen, wenn sie dämmschichtbildende Zusätze enthalten, und daß deshalb eine Dämmschutzwirkung überhaupt nicht erzielt werden kann. Überraschenderweise wurde gefunden, daß die Dichtungsmasse gemäß der Erfindung im Brandfalle nicht abläuft, sondern daß zwar eine ganz erhebliche Erweichung und in gewissem Umfang ein Schmelzen des Bindemittels eintritt, jedoch ein Ablaufen nicht erfolgt. Anscheinend erfolgt bei diesen relativ niedrigen Temperaturen in geringem Umfang bereits eine Gasblasenbildung aufgrund des Gehalts an dämmschichtbildenden Zusätzen, und diese Gasblasen scheinen überraschenderweise ein Ablaufen der Masse zu verhindern. Es kann sich somit im gesamten Bereich der Dichtungsmasse ein Schaum bilden, der die Dämmschichtwirkung hervorruft, wobei gleichzeitig die Abdichtung gewährleistet ist, die durch die Dichtungsmasse erfolgen soll.Although it is known to use vinyl chloride polymers and plasticizers as binders for the production of Use cement or sealing compounds, and that such chlorine-containing polymers are difficult to burn are. However, these thermoplastic binders melt at temperatures that occur in the event of a fire. For example, at temperatures above about 130 ° C, the joints filled with it therefore run out. The expert should have assumed that such putties and sealants would also have to be used in the event of a fire leak if they contain intumescent additives, and that therefore an insulation protection effect cannot be achieved at all. Surprisingly, it has been found that the sealant according to the invention does not expire in the event of a fire, but that a very considerable softening and To some extent, the binder melts, but does not run off. Apparently At these relatively low temperatures, gas bubbles are already formed to a small extent due to the content of intumescent additives, and these gas bubbles seem surprising to prevent the mass from running off. It can thus be in the entire area of the sealant Form a foam, which creates the insulation layer effect, at the same time the seal is guaranteed, which should be done by the sealant.

Als vinylchloridhaltige Polymerisate kommen beispielsweise Mischpolymerisate aus Vinylchlorid und Maleinsäureestern, insbesondere Dibutylmaleinat oder Vinylacetat in Frage, die im Handel als Rohstoffe für die Lack- und Kunststoffindustrie erhältlich sind. Als chlorhaltiges Polymerisat kann beispielsweise auch Polychlorbutadien verwendet werden.Examples of vinyl chloride-containing polymers are Copolymers of vinyl chloride and maleic acid esters, especially dibutyl maleate or vinyl acetate, which are commercially available as raw materials for the paint and plastics industry. Polychlorobutadiene, for example, can also be used as the chlorine-containing polymer.

Weichmacher, die das Polymerisatgemisch lösen und gelatinieren sind beispielsweise aliphatische oder aromatische Ester der Phthalsäure, Adipinsäure, Benzoesäure, Sebazinsäure und der Phosphorsäure, ferner schwerflüchtige chlorierte Paraffine mit einem Chlorgehalt von mindestens 50%. Phosphorsäureester und halogenierte Kohlenwasserstoffe, die der Entflammbarkeit der Masse entgegenwirken, sind dabei bevorzugt.Plasticizers that dissolve and gelatinize the polymer mixture are, for example, aliphatic or aromatic esters of phthalic acid, adipic acid, benzoic acid, sebacic acid and phosphoric acid, also low-volatility chlorinated paraffins with a chlorine content of at least 50%. Phosphoric acid ester and halogenated hydrocarbons, which counteract the flammability of the mass, are included preferred.

Weichmacher, die das Polymerisat nicht lösen und zum Ausschwitzen neigen, haben die Aufgabe, die Masse vor allem in der Oberfläche dauerplastisch zu halten. Zu dieser Klasse gehören beispielsweise nichttrocknende Fettsäureester, z. B. Rizinusöl, chlorierte Paraffine mit einem Chlorgehalt von ca. 40%, Trichloräthylphosphat, Mineralöle, Dibenzyltoluol.Plasticizers, which do not dissolve the polymer and which tend to exude, have the task of To keep the mass permanently plastic, especially in the surface. This class includes, for example, non-drying Fatty acid esters, e.g. B. castor oil, chlorinated paraffins with a chlorine content of approx. 40%, trichloroethyl phosphate, Mineral oils, dibenzyltoluene.

Die erfindungsgemäßen Massen enthalten keine leichtflüchtigen Stoffe. Sie haften gut, auch an glatten Untergründen. Sie können von Hand verarbeitet werden oder auch mit Druckluftpistolen. Im letzten Fall soll die Verarbeitungstemperatur etwa 90° C nicht übersteigen.The compositions according to the invention do not contain any volatile substances. They adhere well, even to smooth ones Subsurfaces. They can be processed by hand or with compressed air guns. In the latter case the processing temperature should not exceed 90 ° C.

Die Feuerwiderstandsdauer nach DIN 4102 beträgt mehr als 90 Minuten. Im Brandfall bilden die Massen eine wärmedämmende, mechanisch stabile Schutzschicht, die vorwiegend aus gasgefüllten Kohlenstoffzellen besteht und selbst nicht brennbar ist. Sie schützt das darunterliegende Material vor Erwärmung und bildet eine wirksame Sperre gegen das Durchtreten von Rauchgasen.The fire resistance period according to DIN 4102 is more than 90 minutes. In the event of a fire, the Masses a thermally insulating, mechanically stable protective layer, which mainly consists of gas-filled carbon cells exists and is not flammable itself. It protects the underlying material from heating up and forms an effective barrier against the passage of smoke gases.
