Abstract
Description
Die Erfindung betrifft Verbundelemente aus Glas oder Kombinationen von Glas mit Kunststoff oder Glas mit plattenförmigen laminierfähigen Materialien, die als Schallschutzglas, Sicherheitsglas oder dekorative Glaselemente Anwendung finden.The The invention relates to composite elements made of glass or combinations of Glass with plastic or glass with plate-shaped laminable materials, as soundproof glass, safety glass or decorative glass elements Find application.
Bericht zum Stand der TechnikReport on State of the art
Die
Herstellung von Schichtaufbauten von Glas mit UV-härtenden
Polymerschichten ist Stand der Technik und wird bevorzugt ausgeführt, indem eine
Glastafel als Grundplatte mit einem den Glasrand umlaufenden elastischen
Abstandhalter versehen wird, der eine Glastafel als Deckplatte haftend mit
der Grundplatte verbindet (z.B.
In den Zwischenraum dieses Glasverbundes wird über eine verbliebene Öffnung das Gießharz eingefüllt, die verbliebene Luft entfernt und die Öffnung versiegelt.In the gap of this glass composite is the remaining opening Cast resin filled, the Removes remaining air and seals the opening.
Das gefüllte Scheibenpaar wird dann mit UV-Licht bestrahlt, in dessen Folge die Harzschicht aushärtet und eine dauerelastische Zwischenschicht bildet. Derartige Gläser werden hauptsächlich als Schallschutzglas, Sicherheitsglas niederer Sicherheitsanforderungen oder dekorative Glaselemente eingesetzt.The filled Disc pair is then irradiated with UV light, as a result of the Hardened resin layer and forms a permanently elastic intermediate layer. Such glasses are mainly as soundproof glass, safety glass with low safety requirements or decorative glass elements used.
Für die Verwendung als Sicherheitsglas höherer Sicherheitsanforderungen können mehrschichtige Aufbauten bis zu etwa 70 mm Dicke erzeugt werden, deren Nachteile sowohl in den Abmessungen der Materialdicke als auch in dem daraus resultierenden hohen Eigengewicht liegen.For the use as safety glass higher Security requirements can multi-layered structures up to about 70 mm thick are produced, their disadvantages both in the dimensions of the material thickness as also in the resulting high weight.
Ein weiterer Nachteil dieses Verfahrens besteht darin, dass bei der Befüllung des Scheibenpaares die Schrumpfung des Harzes während der Polymerisation berücksichtigt werden muss. Diese Gießharze schrumpfen im Verlauf des Aushärteprozesses um etwa 9% bis 12% ihres ursprünglichen Volumens, was zur Folge hat, dass der Scheibenverbund um diesen Betrag überfüllt werden muss, damit nach der Aushärtung eine gleichmäßige Polymerschichtdicke erreicht wird.One Another disadvantage of this method is that in the filling of the disk pair takes into account the shrinkage of the resin during the polymerization must become. These casting resins shrink during the curing process about 9% to 12% of their original Volume, which has the consequence that the disc composite around this Amount to be overcrowded must be so after curing achieved a uniform polymer layer thickness becomes.
Diese Schrumpfung im geschlossenen Volumen führt häufig zu inneren Spannungen zwischen Harz und Glas, wodurch Ablösungen zwischen Harz und Glas auftreten können, die zu erheblichen Problemen führen.These Shrinkage in the closed volume often leads to internal stresses between resin and glass, causing delamination between resin and glass may occur, which lead to significant problems.
Eine weitaus günstigere Variante, sofern der Einsatzzweck als Sicherheitsglas gefordert ist, besteht in der Herstellung von Glas/Harz/Polycarbonat-Verbundglas, bei dem weitaus geringere Schichtdicken verbunden mit wesentlich geringerem Eigengewicht erzielt werden können.A much cheaper Variant, if the intended use as safety glass required is, consists in the production of glass / resin / polycarbonate laminated glass, at the much lower layer thicknesses associated with essential lower dead weight can be achieved.
Diese Laminate werden mit chemisch härtenden Polyurethanharzen hergestellt, deren Nachteile einerseits in den Kosten der Harze, und andererseits in deren schwer fließbarer Konsistenz in nicht ausgehärtetem Zustand und somit in der langen Verarbeitungszeit sowohl im Füllprozess, als auch im chemischen Aushärtungsprozess begründet sind.These Laminates are chemically hardened Polyurethane resins produced, the disadvantages of one hand in the Cost of resins, and on the other hand in their difficult flowable consistency in uncured Condition and thus in the long processing time both in the filling process, as well as in the chemical curing process justified are.
Es ist bisher nicht gelungen die kostengünstigeren schnell aushärtenden UV-Gießharze für diesen Zweck einzusetzen.It So far, it has not been possible to achieve the more cost-effective, fast-curing UV casting resins for this Use purpose.
Der Grund dafür liegt neben der chemischen Beständigkeit des Kunststoffes gegenüber einigen Gießharzen hauptsächlich in der Differenz der linearen thermischen Ausdehnungskoeffizienten von Glas und Polycarbonat (Glas: 9,0×10–6/K; Polycarbonat: 65×10–6/K).The reason for this, in addition to the chemical resistance of the plastic to some casting resins, lies mainly in the difference between the linear thermal expansion coefficients of glass and polycarbonate (glass: 9.0 × 10 -6 / K, polycarbonate: 65 × 10 -6 / K).
Die Polyurethanharze sind dauerelastisch und kompensieren von daher die unterschiedliche Ausdehnung.The Polyurethane resins are permanently elastic and therefore compensate the different extent.
Die UV-härtenden Gießharze sind ebenfalls dauerelastisch, lösen sich aber wegen der Volumenkontraktion (Schrumpfung im Aushärteprozeß) und der dabei auftretenden Reaktionsenthalpie bereits während des Aushärtens von der Polycarbonat-Unterlage ab, bzw. delaminieren nach kurzer Zeit des Abkühlens.The UV-curing casting resins are also permanently elastic, solve but because of the volume contraction (shrinkage in the curing process) and the thereby occurring reaction enthalpy already during the curing of the polycarbonate underlay, or delaminate after a short time of cooling.
Ziel der ErfindungObject of the invention
Die Erfindung hat zum Ziel die Nachteile der bisher bekannten Verfahren zu beseitigen um eine homogene Polymerschicht zu erzeugen, die neben guter Haftung zu den zu verbindenden laminatbildenden Schichten, die unterschiedliche thermische Ausdehnung zwischen den laminatbildenden Schichten ausgleicht.The Invention has the aim of the disadvantages of the previously known methods to eliminate a homogeneous polymer layer, in addition to good Adhesion to the laminating layers to be joined, the different compensates thermal expansion between the laminating layers.
Darlegung des Wesens der Erfindungstatement the essence of the invention
Das Ziel der Erfindung ist die Herstellung von Verbundglas mit spannungsfreien Polymerschichten, beispielsweise als Glas/Harz/Glas oder Glas/Harz/Polycarbonat/Harz/Glas- Aufbauten unter Verwendung von UV-härtenden Gießharzen.The The aim of the invention is the production of laminated glass with stress-free Polymer layers, for example as glass / resin / glass or glass / resin / polycarbonate / resin / glass Structures using UV-curing casting resins.
Diese Aufgabenstellung wird erfinderisch dadurch gelöst, indem das Gießharz flüssig auf die Grundplatte aufgebracht wird und unter Bestrahlung mit UV-Licht in einer atmosphärisch offenen-, oder Schutzgas-, oder Gasgemisch- Atmosphäre so weit polymerisiert, dass eine gelierte Grundschicht aufgebaut wird, die in der Lage ist die nachfolgend aufgelegte Glasscheibe schwimmend zu tragen.This task is inventively achieved by the casting resin is applied liquid to the base plate and under irradiation with UV light in an atmosphere open, or protective gas, or gas mixture atmosphere so far polymerizes that a gelled base layer is built, which is able to float the subsequently applied glass sheet.
Die noch flüssige Deckschicht beträgt dabei wenige Zehntel mm, je nach Dauer der Bestrahlungszeit. Zum Zeitpunkt der Ausbildung der gelierten Polymerschicht ist die Reaktion so weit fortgeschritten, dass die reaktionsbedingte Schrumpfung nahezu vollständig stattgefunden hat.The still liquid Cover layer is a few tenths of a millimeter, depending on the duration of the irradiation time. To the Time of formation of the gelled polymer layer is the reaction so far advanced that the reaction-related shrinkage almost complete took place.
Die freie Flüssigkeitsoberfläche wird durch einen Rand fixiert, der eine größere Fläche als die zu laminierende Grundplatte bildet, wodurch eine die Grundplatte umlaufende Pufferzone entsteht, in der das Harz, vergleichbar einem absinkenden Flüssigkeitsspiegel der Schrumpfung nachgibt und eine gleichmäßige Schichtdicke der Polymerschicht bildet. Voraussetzung dafür ist ein ebener Untergrund, der exakt waagerecht justiert ist.The free liquid surface becomes fixed by an edge that has a larger area than the one to be laminated Base plate forms, whereby a base plate surrounding the buffer zone arises in which the resin, comparable to a sinking liquid level the shrinkage yields and a uniform layer thickness of the polymer layer forms. Prerequisite for this is a level surface adjusted exactly horizontally.
Die vollständige Aushärtung erfolgt anschließend nach dem Auflegen der Deckscheibe in sauerstofffreier Atmosphäre zu einer homogenen Polymerschicht, lediglich durch erneute Zuführung von UV-Strahlung. Der verbliebene geringe Anteil der Schrumpfung wird durch die frei schwimmend aufliegende Scheibe vollständig kompensiert.The full curing takes place afterwards After placing the cover plate in an oxygen-free atmosphere to a homogeneous polymer layer, only by renewed supply of UV radiation. The remaining small proportion of shrinkage is released by the floating disc completely compensated.
Wegen des spannungsfreien Aufbaus besteht neben der Herstellung von Verbundgläsern die Möglichkeit der Herstellung von beispielsweise Glas-Polycarbonat Verbundsystemen, die als Sicherheitsglas mit hohen Sicherheitsanforderungen Verwendung finden können.Because of The tension-free construction is possible in addition to the production of laminated glass the production of, for example, glass-polycarbonate composite systems, as Safety glass with high safety requirements find use can.
Darüber hinaus lässt sich das Verfahren auch auf großflächige Glastafel-, bzw. Glas- Polycarbonat-Verbundsysteme anwenden, die mit den klassischen Füllverfahren technisch schwer oder nicht zu beherrschen sind, z.B Jumbo-Formate (6×3,21 m).Furthermore let yourself the method also applies to large-scale glass panel, or glass-polycarbonate composite systems that are compatible with the classic filling technically difficult or impossible to control, for example jumbo formats (6 x 3.21 m).
