Abstract

Fireproof sealant materials comprising silicones and fireproofing additives contain one or more organic chlorine compounds (A) and at least one solid substance (B) that forms a ceramic when exposed to fire.

Description

Brandhemmende Massen werden in erheblichem Umfang, insbesondere zum Abdichten in Bauwerken von Fugen, Rohr- und Leitungsdurchbrüchen und dergleichen eingesetzt. Aufgrund der relativ hohen Temperaturbeständigkeit und der guten Elastizität handelt es sich dabei bevorzugt um Dichtmassen auf Silikonbasis. Zur Verbesserung ihrer Eigen­ schaften enthalten sie verschiedene Brandschutzadditive.Fire retardant masses are used to a considerable extent, especially for sealing used in structures of joints, pipe and line openings and the like. Due to the relatively high temperature resistance and good elasticity, it acts preferably silicone-based sealing compounds. To improve their own they contain various fire protection additives.

So sind Brandschutz-Dichtmassen auf Silikonbasis bekannt, welche organische Brom­ verbindungen als brandhemmende Additive enthalten. Hiermit soll insbesondere die Ent­ zündung durch IR-Strahlung verhindert werden. Weiter sind Brandschutzdichtmassen auf Silikonbasis bekannt, welche als brandhemmende Additive Aluminiumhydroxid, intumes­ zierende Bestandteile, wie Blähgraphit oder zur Erhöhung der Temperaturstabilität Zu­ sätze wie Eisenoxidpigmente enthalten. Gegenüber den Dichtmassen, die zur Erhöhung der Feuerwiderstandsdauer oder der Temperaturstabilität Aluminiumhydroxid, Blähgra­ phit oder Eisenoxidpigmente enthalten, zeigen die organische Bromverbindungen enthal­ tenden Silikondichtmassen die beste Wirkung. Jedoch mußte die Weiterbenutzung die­ ser Dichtmassen wegen ihrer kanzerogenen Wirkung untersagt werden.Fire protection sealing compounds based on silicone are known, which are organic bromine contain compounds as fire-retardant additives. With this, the Ent ignition can be prevented by IR radiation. Fire protection sealants are also on Known silicone base, which acts as a fire retardant additive aluminum hydroxide, intumes decorative components, such as expanded graphite or to increase the temperature stability contain sets such as iron oxide pigments. Compared to the sealants that increase the fire resistance duration or the temperature stability aluminum hydroxide, expandable gra Contain phit or iron oxide pigments, the organic bromine compounds contain silicone sealants have the best effect. However, continued use had to sealing compounds are prohibited because of their carcinogenic effects.

Aufgabe der vorliegenden Erfindung ist es demzufolge, brandhemmende Dichtmassen auf Silikonbasis zur Verfügung zu stellen, welche frei sind von kanzerogenen Wirkungen und dennoch überlegene, brandhemmende Wirkung besitzen. Gegenstand der Erfin­ dung sind demgemäß Brandschutz-Dichtmassen auf Silikonbasis mit Gehalten an Brandschutzadditiven, wobei die Dichtmasse erfindungsgemäß als Additiv eine organi­ sche Chlorverbindung und einen unter Brandbedingungen keramisierenden Feststoff enthält. The object of the present invention is therefore to provide fire-retardant sealing compounds silicone-based, which are free of carcinogenic effects and yet have a superior, fire-retardant effect. Object of the inven Accordingly, fire protection sealing compounds with a silicone content are present Fire protection additives, the sealing compound according to the invention as an organic additive cal chlorine compound and a solid ceramicizing under fire conditions contains.  

Insbesondere feste organische Chlorverbindungen haben sich bewährt, wie beispiels­ weise PVC-Pulver, Chlorparaffine, chlorierte Polyethylene, chlorierte Polypropylene oder Gemische solcher Substanzen. Die organischen Chlorverbindungen haben den Vorteil, daß sie insbesondere Entzündungen durch IR-Strahlung entgegenwirken.Solid organic chlorine compounds in particular have proven themselves, for example such as PVC powder, chlorinated paraffins, chlorinated polyethylenes, chlorinated polypropylenes or Mixtures of such substances. The organic chlorine compounds have the advantage that they counteract inflammation in particular by IR radiation.

Die keramisierenden Feststoffe sind Materialien auf anorganischer bzw. mineralischer Basis. Sie liegen regelmäßig in feinteiliger Form, namentlich in Form von Pulvern, Gra­ nulaten oder gefrittet vor. Unter Brandbedingungen, namentlich bei Brandtemperatur, bilden sie eine feste Struktur wie beispielsweise ein Gerüst, was sowohl durch Kristallän­ derung, vorzugsweise aber auch durch oberflächliche Schmelz- oder Erweichungsvor­ gänge der Partikel und teilweise Verbacken mit Nachbarpartikeln erfolgen kann. Die ke­ ramisierenden Feststoffe können silikatischen, aluminatischen, boratischen und/oder phosphatischen Ursprungs sein, wie beispielsweise silikatische, boratische und/oder phosphatische Gläser. Die keramisierenden Feststoffe schmelzen meist im Bereich von 250° bis 930°, insbesondere 350° bis 750°C. Die keramisierenden Füllstoffe übernehmen im Brandfalle nach der thermischen Zersetzung der Silikonpolymere als festes Gerüst brandhemmende Funktion.The ceramizing solids are materials based on inorganic or mineral Base. They are regularly in finely divided form, especially in the form of powders, gra nulates or fried. Under fire conditions, especially at fire temperature, they form a solid structure such as a scaffold, which is due to both crystalline change, but preferably also by superficial melting or softening of the particles and partial caking with neighboring particles. The ke ramizing solids can be silicate, aluminate, borate and / or be of phosphatic origin, such as, for example, silicate, borate and / or phosphatic glasses. The ceramizing solids mostly melt in the range of 250 ° to 930 °, especially 350 ° to 750 ° C. The ceramicizing fillers take over in the event of fire after the thermal decomposition of the silicone polymers as a solid framework fire retardant function.

Die erfindungsgemäßen Brandschutz-Dichtmassen haben sich insbesondere zur Ver­ wendung für Brandschutzverglasung, die im Brandfalle durchsichtig bleiben (G-Vergla­ sung), bewährt. Sie können dabei auch als Dichtmassen bzw. Fugendichtmassen auf der feuerabgewandten Seite des Bauteils eingesetzt werden, weil sie gerade einer Entzün­ dung durch IR-Strahlung entgegenwirken.The fire protection sealants according to the invention have in particular for Ver application for fire protection glazing that remains transparent in the event of fire (G-glazing solution), proven. They can also be used as sealing compounds or joint sealing compounds on the side of the component facing away from the fire, because they are igniting counteracting by IR radiation.

Die erfindungsgemäßen Additive können in Mengen von 3 bis 35 Gew.-%, vorzugs­ weise 5-25 Gew.-%, bezogen auf die Gesamt-Dichtmasse, enthalten sein. Das Ver­ hältnis von Chlorverbindung zu keramisierendem Feststoff liegt dabei im allgemeinen im Verhältnis von 1 : 1 bis 1 : 5. Die organische Chlorverbindung, die regelmäßig als Pulver vorliegt und der feinteilige keramisierende Feststoff sind im allgemeinen chemisch inert und können in der Formulierung als Füllstoff eingesetzt werden, so daß die gewünsch­ ten mechanischen Eigenschaften problemlos einstellbar sind. Darüber hinaus können die üblichen Additive, wie Füllmittel, Pigmente, viskositätsbeeinflussende Verbindungen, Stabilisatoren und dergleichen enthalten sein. The additives according to the invention can be present in amounts of 3 to 35% by weight as 5-25 wt .-%, based on the total sealant may be included. The Ver Ratio of chlorine to ceramizing solid is generally in Ratio of 1: 1 to 1: 5. The organic chlorine compound, which is regularly used as a powder is present and the fine-particle ceramizing solid are generally chemically inert and can be used in the formulation as a filler, so that the desired mechanical properties can be easily adjusted. In addition, the usual additives, such as fillers, pigments, viscosity-influencing compounds, Stabilizers and the like may be included.  

Als Silikonbasis haben sich raumtemperaturvernetzende Systeme z. B. α,ω-Dimethylhydroxipolydimethylsiloxane unterschiedlicher Viskosität mit Acetoxi-, Oxymo-, Amido- oder Alkoxysiloxanen als Vernetzer bewährt.As a silicone base, room temperature crosslinking systems have, for. B. α, ω-dimethylhydroxipolydimethylsiloxanes of different viscosities with acetoxy, oxymo, Amido or alkoxysiloxanes have proven successful as crosslinkers.
