Description
Verfahren zur Herstellung eines Mehrschichtenglases mit veränderlicher Lichtdurchlässigkeit Das Hauptpatent betrifft ein Verfahren zur Herstellung eines Mehrschichtenglases, bei welchem eine Veränderung der Lichtdurchlässigkeit unter Temperatureinfluß dadurch erreicht wird, daß eine Zwischen-Schicht aus thermoplastischen Kunststoffen verwendet wird, in der Hydratsalze enthalten sind, die bei Erhöhung der Temperatur ihr Wasser abgeben, wobei dieses im Kunststoff fein dispergiert wird und damit eine Trübung desselben verursacht. Bei normaler Temperatur geht das Wasser an die Salze zurück, so daß die Scheibe wieder klar durchsichtig wird.Process for the production of a multilayer glass with variable Light transmission The main patent relates to a method for producing a Multi-layer glass, in which a change in light transmission under Influence of temperature is achieved in that an intermediate layer of thermoplastic Plastics are used, in the hydrate salts are contained, which increase the temperature give off their water, which is finely dispersed in the plastic and thus causing it to become cloudy. At normal temperature the water goes back to the salts so that the pane becomes clear again.
Die Verbindung der Zwischenschicht mit den Deckglasscheiben geschieht gemäß dem Hauptpatent in an sich bekannter Weise durch Zusammenlegen einer beschichteten Scheibe mit einer unbeschichteten Scheibe oder einer zweiten beschichteten Scheibe unter Verwendung von Weichmachern.The interlayer is connected to the cover glass panes according to the main patent in a manner known per se by combining a coated one Disc with an uncoated disc or a second coated disc using plasticizers.
In Abänderung dieses Verfahrens kann die Verbindung der die Zwischenschicht tragenden Scheibe nach vorhergehendem Klimatisieren der Zwischenschicht mit der Deckglasscheibe oder einer zweiten beschichteten und klimatisierten Scheibe in bekannter Weise auch unter Verwendung von härtbaren Harzen (ungesättigten Polyesterharzen, Epoxyharzen) mit oder ohne Glasfaserverstärkungen erfolgen. Dabei können die Scheiben entweder auf ihrer ganzen Fläche oder nur am Rande miteinander verbunden werden, wobei im ersteren Falle eine Verbindung des Harzes mit der vorher klimatisierten Zwischenschicht, dem zweckmäßigerweise auf etwa 1 bis 3 cm schichtfrei gelassenen Glasrand und der Deckglasscheibe eintritt, während im zweiten Falle die Verklebung nur an den schichtfreien Rändern der Scheiben erfolgt. In beiden Fällen kann nach dem bekannten Kammerverfahren gearbeitet werden, d. h., der zwischen den Scheiben auszufüllende Raum wird unter Verwendung von Abstandhaltern (Butyralfolie od. dgl.) mit einem später leicht entfernbaren Material (z. B. Papierband) umklebt und der auf diese Weise gebildete Hohlraum, gegebenenfalls nach vorheriger Einbringung des Glasfasergewebes oder -vließes, mit dem Harz gefüllt.Modifying this process can be the connection of the intermediate layer supporting disc after previous air conditioning of the intermediate layer with the Cover glass pane or a second coated and air-conditioned pane in known Also using curable resins (unsaturated polyester resins, Epoxy resins) with or without glass fiber reinforcements. The discs be connected to one another either over their entire surface or only at the edge, in the former case a compound of the resin with the previously air-conditioned Intermediate layer, which is expediently left free of layers for about 1 to 3 cm The edge of the glass and the cover glass pane occurs, while in the second case the gluing occurs takes place only at the layer-free edges of the panes. In both cases, after the known chamber method can be used, d. i.e., the one between the panes The space to be filled is made using spacers (butyral film or the like). covered with a later easily removable material (e.g. paper tape) and the cavity formed in this way, optionally after prior introduction of the Fiberglass fabric or fleece, filled with the resin.
Die gemäß dem Hauptpatent aus Thermoplasten, Weichmachern und Hydratsalzen gebildete Zwischenschicht wird zweckmäßig nach dem Klimatisieren mit einer neutralen Lackschicht oder in einer anderen Ausführungsform einer zusätzlichen, feuchtigkeitsbindenden Schicht, z. B. einer Polyvinylalkoholfolie, oder auch dieser nur allein versehen, wobei diese Schicht durch Aufgießen der gelösten Stoffe oder durch Rufpressen aufgebracht werden kann.The ones according to the main patent made of thermoplastics, plasticizers and hydrate salts formed intermediate layer is expediently after air conditioning with a neutral Lacquer layer or, in another embodiment, an additional, moisture-binding one Layer, e.g. B. a polyvinyl alcohol film, or this only provided alone, this layer being applied by pouring on the dissolved substances or by pressing can be.
Bei Verwendung von Silikatglas als Scheibenmaterial des Mehrschichtenglases kann die Haftfestigkeit des Harzes am Glase in an sich bekannter Weise durch Vorbehandlung mit Haftmitteln, wie Polyvinylpyrrolidon, Vinyltrichlorsilan, Chromchloridmethacrylat, verbessert werden.When using silicate glass as the pane material of the multilayer glass can improve the adhesive strength of the resin on the glass in a known manner by pretreatment with adhesives such as polyvinylpyrrolidone, vinyltrichlorosilane, chromium chloride methacrylate, be improved.
