Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer optisch klaren Brandschutz-Glaseinheit aus zumindest zwei einen Scheibenzwischenraum zwischen einander bildenden Glasscheiben, in dem eine Brandschutzmasse angeordnet ist.The invention relates to a method of manufacture at least an optically clear fire protection glass unit two forming a space between the panes Glass panes in which a fire protection compound is arranged.

Im Rahmen der (aus der Praxis) bekannten gattungsgemäßen Maß­ nahmen wird eine Lösung aus Aluminiumphosphat in Wasser auf eine horizontal gelagerte Glasscheibe aufgebracht und an Luft, gegebenenfalls unter vorsichtiger Einwirkung von Wärme, bis auf einen Wassergehalt von etwa 20 Gewichtsprozent zur Brand­ schutzmasse getrocknet. Dabei erreicht man Schichtdicken der Brandschutzmassen von 0,2 bis 1,5 mm. Danach wird eine weitere Glasscheibe aufgebracht und eine Verbundglaseinheit herge­ stellt. Entsprechend verfährt man bei der Herstellung von Ver­ bundglaseinheiten mit mehr als zwei Glasscheiben und mehr als einer aus Brandschutzmasse bestehenden Zwischenschicht. Die bekannten Maßnahmen führen zu alterungsbeständigen Brand­ schutzmassen in den Brandschutz-Glaseinheiten, sind jedoch herstellungstechnisch aufwendig und in bezug auf die Brand­ schutzwirkung wegen des verhältnismäßig geringen Wassergehal­ tes in der Brandschutzmasse verbesserungsbedürftig. Einen höheren Gehalt an Wasser enthalten die Brandschutzmassen von Brandschutz-Glaseinheiten, die aus einem Polymer in Form eines organischen Hydrogels bestehen, welches ein im Brandfalle schäumendes, mit dem Gel kompatibles Salz aufweist, jedoch soll durch das Schäumen eine Veränderung der Dickendimension ebenso verhindert werden wie das Ausfließen der Brandschutz­ masse im Brandfall. Hier kann die Alterungsbeständigkeit noch verbessert werden.Within the scope of the generic dimension known (from practice) was taken up a solution of aluminum phosphate in water a horizontally stored glass pane is applied and exposed to air, if necessary with careful exposure to heat, until to a water content of about 20 percent by weight for fire protective compound dried. Layer thicknesses can be achieved Fire protection measures from 0.2 to 1.5 mm. After that, another one Glass pane applied and a laminated glass unit here poses. The procedure for the production of Ver bundled glass units with more than two panes of glass and more than an intermediate layer made of fire protection compound. The known measures lead to aging-resistant fire protective masses in the fire protection glass units, however technically complex and in relation to the fire protective effect due to the relatively low water content tes in the fire protection composition in need of improvement. One The fire protection compounds from Fire protection glass units made of a polymer in the form of a organic hydrogel, which is a fire has foaming salt compatible with the gel, however foaming is supposed to change the thickness dimension are prevented as well as the leakage of fire protection mass in case of fire. Here the aging resistance can still be improved.

Der Erfindung liegt die Aufgabe zugrunde, ein einfaches Ver­ fahren anzugeben, welches zu optisch klaren Brandschutz-Glas­ einheiten geringer Dicke mit nichtsdestoweniger hoher Brand­ schutzwirkung und hoher Alterungsbeständigkeit der Brand­ schutzmasse führt.The invention has for its object a simple Ver drive indicate which to optically clear fire protection glass units of small thickness with nonetheless high fire protective effect and high aging resistance of the fire protective compound leads.

Zur Lösung dieser Aufgabe lehrt die Erfindung, daß aus Alu­ miniumphosphat, Acrylsäurederivaten, einem Photohärter und Wasser eine dünnflüssige Brandschutz-Vormasse hergestellt wird, die in den Scheibenzwischenraum eingebracht oder auf eine der Glasscheiben aufgegossen wird, und daß die Brand­ schutz-Vormasse durch Bestrahlen mit ultraviolettem Licht in die Brandschutzmasse umgewandelt wird. Wird die Brandschutz- Vormasse auf eine der Glasscheiben aufgegossen, so erfolgt in diesem Zustand auch die Bestrahlung - und hernach wird die zweite Glasscheibe, den Scheibenzwischenraum bildend, aufge­ bracht. Nach bevorzugter Ausführungsform der Erfindung wird mit Monoaluminiumphosphat und/oder Monoaluminiumhydrophosphat sowie mit Methylacrylamid und/oder Acrylamid gearbeitet. Die Dicke der Brandschutzmasse soll im Bereich von 0,2 bis 3 mm liegen. Es versteht sich, daß die Bestrahlung mit dem ultra­ violetten Licht auch durch die Glasscheiben bzw. eine der Glasscheiben hindurch erfolgen kann. Eine geeignete Wellen­ länge des ultravioletten Lichtes kann durch Versuche leicht gefunden werden. Bei dem erfindungsgemäßen Verfahren läßt sich ein im Vergleich mit den ersten bekannten Maßnahmen, von denen die Erfindung ausgeht, wesentlich erhöhter Wassergehalt in der Brandschutzmasse unterbringen. Das gilt insbesondere für die Ausführungsform der Erfindung, die dadurch gekennzeichnet ist, daß 30 bis 60 Gewichtsteile Aluminiumphosphat und 5 bis 40 Gewichtsteile Acrylsäurederivate sowie maximal etwa ein Ge­ wichtsteil eines Photohärters und 20 bis 55 Gewichtsteile Wasser zu der Brandschutz-Vormasse angemacht werden und diese wie angegeben in die Brandschutzmasse umgewandelt wird. Ohne Schwierigkeiten läßt sich hier der Wassergehalt der Brand­ schutz-Vormasse so einstellen, daß die Brandschutzmasse 30 bis 55 Gewichtsprozent Wasser aufweist. Es versteht sich, daß man der Brandschutz-Vormasse Vernetzungsmittel und/oder Haftver­ mittler beigeben kann, die das Aufschäumen und/oder die Haftung an den Glasscheiben verbessern. Insbesondere kann es sich um geeignete Silane handeln. Sie können bis zu 5 Gewichtsteilen beigegeben werden.To achieve this object, the invention teaches that aluminum minium phosphate, acrylic acid derivatives, a photo hardener and Water a thin, fire-resistant pre-compound is brought into the space between the panes or on one of the glass panes is poured on, and that the fire Protective pre-mass by exposure to ultraviolet light in the fire protection compound is converted. If the fire protection Pour the pre-mass onto one of the glass panes, in this state also the radiation - and after that the second glass pane, forming the space between the panes, opened brings. According to a preferred embodiment of the invention with mono aluminum phosphate and / or mono aluminum phosphate and worked with methyl acrylamide and / or acrylamide. The The thickness of the fire protection compound should be in the range of 0.2 to 3 mm lie. It is understood that the radiation with the ultra violet light also through the glass panes or one of the Glass panes can be made. A suitable waves length of ultraviolet light can be easily experimented being found. In the method according to the invention, a compared to the first known measures, of which the invention is based, significantly increased water content in the Place fire protection compound. This is especially true for the Embodiment of the invention, which is characterized in that 30 to 60 parts by weight of aluminum phosphate and 5 to 40  Parts by weight of acrylic acid derivatives and a maximum of about one Ge important part of a photo hardener and 20 to 55 parts by weight Water is made into the fire protection pre-mix and this is converted into the fire protection compound as indicated. Without The water content of the fire can cause difficulties here Adjust the protective pre-mass so that the fire protection mass 30 to Has 55 weight percent water. It goes without saying that one the fire protection pre-crosslinking agent and / or adhesive can add the foaming and / or the Improve adhesion to the glass panes. In particular, it can are suitable silanes. You can have up to 5 Parts by weight are added.
