Abstract

Plastics are continuously coated with glass by guiding a flat glass at constant velocity in a zone for heating to glass softening temperatures. In this zone, only a narrow strip of the flat glass is converted to the liquid state. The flat glass is drawn out of this zone to form a glass film, the draw-off rate being a multiple of the velocity of feeding of the flat glass. The glass film thus formed is combined under tensile stress with the plastic to be coated and bonded to the plastic under the effect of pressure and/or heat, preferably with the use of an interposed hot-melt adhesive film.

Description

Verfahren und Vorrichtung zur kontinuier- Method and device for continuous

lichen Beschichtung von Kunststoffen mit Glas Die Erfindung betrifft ein Verfahren zur kontinuierlichen Beschichtung von Kunststoffen mit Glas und eine Vorrichtung zur Durchführung dieses Verfahrens. Das erfindungsgemäße Verfahren ist insbesondere zur Herstellung von Scheiben für Verkehrsfahrzeuge, Gebäude, Schaufenster, als Verkleidungen und Kacheln für architektonisXchç Zwecke sowie zur Herstellung von glasfolienverstärkten Kunststoffen geeignet. union coating of plastics with glass The invention relates a process for the continuous coating of plastics with glass and a Apparatus for carrying out this process. The inventive method is especially for the production of windows for traffic vehicles, buildings, shop windows, as cladding and tiles for architectural purposes as well as for manufacturing suitable for glass film reinforced plastics.

Kratzfest beschichtete Kunststoffe auf der Basis von Polycarbonaten und Polymethylmethacrylaten besitzen als bruchhemmende Sichtscheiben in Transport- und Industriefahrzeugen als Schutzverglasungen und dgl. eine besondere Bedeutung.Scratch-resistant coated plastics based on polycarbonates and polymethyl methacrylates are used as break-resistant lenses in transport and industrial vehicles as protective glazing and the like. A special meaning.

Die Beschichtung ist im allgemeinen 5 - 10 /um dick und besteht aus harten Polysiloxanen, damit dem Kunststoff beim ständigen Reinigen eine genügende Kratzfestigkeit verliehen werden kann. Aber auch mit harten Polysiloxanen beschichteten Sichtscheiben, z.B. für Transportfahrzeuge widerstehen den üblichen oft sehr harten automatisierten Reinigungsmethoden auf die'Dauer nicht. Es besteht daher ein Bedarf an beschichteten Kunststoffscheiben, deren Kratzfestigkeit diejenige der Gläser aufweist, da diese mehr als die zehnfache Lebensdauer der bisher bekannten Kunststoffbeschichtungen besitzen.The coating is generally 5 - 10 / µm thick and consists of hard polysiloxanes, so that the plastic is given a sufficient amount during constant cleaning Scratch resistance can be imparted. But also coated with hard polysiloxanes Viewing panes, e.g. for transport vehicles withstand the usual, often very tough, automated ones Cleaning methods do not last for a long time. There is therefore a need for coated ones Plastic panes, the scratch resistance of which has that of the glasses, as this more than ten times the service life of the plastic coatings known to date own.

Die Beschichtung sollte ferner sehr gut haften, gute optische Qualitäten aufweisen und sich auch bei langem Gebrauch nicht verfärben.The coating should also adhere very well, good optical qualities and will not discolour even after long use.

Der Erfindung liegt daher die Aufgabe zugrunde, Glasfolien mit guten optischen Eigenschaften und gleichmäßiger Dicke in wirtschaftlicher Weise kontinuierlich herzustellen und diese direkt im Anschluß an ihre Herstellung auf den Kunststoff aufzubringen. Das resultierende Produkt sollte dann die Kratzfestigkeit von Glas und die hohe Bruchfestigkeit von Kunststoffen zusammen mit dessen wesentlich geringerem Gewicht'vereinen.The invention is therefore based on the object of providing glass films with good optical properties and uniform thickness in an economical way continuously and these directly after their production on the plastic to raise. The resulting product should then have the scratch resistance of glass and the high breaking strength of plastics together with its much lower Weight 'unite.

Es ist bekannt, Glasfolien bis herab zu etwa 1 um Stärke durch Blasen herzustellen. Die entstehenden Gebilde weisen jedoch neben einer unregelmäßigen Dicke auch keine ebene Oberfläche auf; diese ist vielmehr zylindrisch oder sphärisch gekrümmt. Zu dem krumpeln diese Gebilde und zerknittern zu unbrauchbaren Folien, wenn der Innendruck nach dem Blasvorgang wieder rückgängig gemacht wird. Eine wesentliche Aufgabe der vorliegenden Erfindung liegt daher auch darin, ein Verfahren zu entwickeln, das es gestattet, kontinuierlich in großen Mengen ebene Folien aus Glas herzustellen und diese solange unter Zugspannung zu halten, bis sie fest auf der damit zu beschichtenten Kunststoffoberfläche aufgebracht sind.It is known to blow glass films down to about 1 µm in thickness to manufacture. The resulting structures show, however, next to an irregular one Also, do not thicken a flat surface; it is rather cylindrical or spherical curved. In addition, these structures crumple and crumple into unusable foils, if the internal pressure is released again after the blowing process. An essential one The object of the present invention is therefore also to develop a method which makes it possible to continuously produce large quantities of flat sheets of glass and to keep them under tension until they are firmly attached to the surface to be coated Plastic surface are applied.

Es hat sich nun gezeigt, daß sich diese Aufgabe mit einem Verfahren lösen läßt, bei dem ein Flachglas mit konstanter Geschwindigkeit in eine Zone zum Aufheizen auf die Glaserwei- chungstemperatur geführt wird, in welcher nur ein schmaler Streifen des Flachglases in den fließfähigen Zustand gebracht wird und aus dieser Zone das Flachglas zu einer Glasfolie ausgezogen wird, wobei die Abziehgeschwindigkeit ein Vielfaches der Geschwindigkeit zum Nachführen des Flachglases beträgt, und wenn die Glasfolie unter Zugspannung mit dem zu beschichtenden Kunststoff zusammengeführt und unter Einwirkung von Druck und/oder Wärme mit dem Kunststoff verbunden wird. Vorteilhafte Weiterbildungen dieses Verfahrens sind in den Unteransprüchen 2 bis 9 erläutert, während die Ansprüche 10 und 11 eine Vorrichtung zur Durchführung dieses Verfahrens betreffen.It has now been shown that this task can be achieved with one method can solve, in which a flat glass at constant speed in a zone for Heating up to the glass chung temperature is performed in which only a narrow strip of the flat glass is brought into the flowable state and from this zone the flat glass is pulled out to form a glass film, the Pull-off speed is a multiple of the speed for tracking the flat glass is, and when the glass film is under tension with the plastic to be coated merged and under the action of pressure and / or heat with the plastic is connected. Advantageous developments of this method are set out in the subclaims 2 to 9 explained, while claims 10 and 11 a device for implementation concern this procedure.

Erfindungsgemäß wurde festgestellt, daß sich durch kontinuierliches Einführen von normalem Flachglas einer Stärke von etwa 1 - 3 mm über eine Vorwärmzone in eine schmale Heizzone, in welcher ein möglichst schmaler Streifen von weniger als 30 mm Breite in den fließfähigen Zustand gebracht wird, und durch kontinuierliches Abziehen von Glasfolien aus dieser Heizzone ein optisch einwandfreies Folienband erzeugen läßt. Diese Folie kann bis zu ihrem festen Aufbringen auf der Kunststoffoberfläche so unter Zugspannung gehalten werden, daß keine die optischen Qualitäten beeinträchtigenden Runzeln, Knicke und Dopplungen entstehen.According to the invention it was found that by continuous Insertion of normal flat glass with a thickness of about 1 - 3 mm via a preheating zone into a narrow heating zone, in which a narrow strip of less than 30 mm wide is brought into the flowable state, and by continuous Removal of glass foils from this heating zone an optically perfect foil tape can be generated. This film can be applied until it is firmly attached to the plastic surface are kept under tension in such a way that they do not impair the optical qualities Wrinkles, creases and doublings arise.

Vorzugsweise wird diese Glas folie unter Verwendung eines Klebers mit der Kunststoffoberfläche verbunden. Für diesen Zweck ist insbesondere eine Schmelzklebefolie auf der Basis von Polyvinylbutyral geeignet. Hierzu wird das Glasfolienband mit dem Schmelzkleberband durch eine Heizzone geführt und im Anschluß daran über mit Silikongummi beschichtete Walzen auf die Kunststoffoberfläche angedrückt.This glass film is preferably made using an adhesive connected to the plastic surface. A hot-melt adhesive film is particularly useful for this purpose on the basis of polyvinyl butyral suitable. For this purpose, the glass film tape is used the hot melt adhesive tape passed through a heating zone and then over with Silicone rubber coated rollers pressed onto the plastic surface.

Die Grundvoraussetzung des erfindungsgemäßen Verfahrens ist eine genaue Regelung der Nachführgeschwindigkeit des Flach- glases in die schmale Heizzone zur Erweichung und eine exakte Regelung der Abzugsgeschwindigkeit des Glasfolienbandes, die mit der Nachführgeschwindigkeit abgestimmt sein muß. Vorzugsweise beträgt die Nachführungsgeschwindigkeit des Flachglases ca. 3 - 30 mm/min und die Abzugsgeschwindigkeit ca. 0,3 - 6m/min.The basic requirement of the method according to the invention is an exact one Control of the tracking speed of the flat glass in the narrow Heating zone for softening and precise control of the take-off speed of the glass film strip, which must be coordinated with the tracking speed. Preferably the Tracking speed of the flat glass approx. 3 - 30 mm / min and the take-off speed approx. 0.3 - 6m / min.

Dabei werden Glasfolien mit einer Dicke zwischen 2 - 60 um gebildet. Unterhalb von 2 /um weisen die Glasfolien keinen ausreichenden Widerstand gegenüber dem Abzugsmechanismus mehr auf. Glasfolienstärken über etwa ca. 60 um sind wegen der mit dieser Dicke zusammenhängenden Sprödigkeit des Glases nicht geeignet.Glass foils with a thickness between 2 and 60 μm are formed in the process. Below 2 / µm, the glass films do not have sufficient resistance to this the trigger mechanism more. Glass film thicknesses over about 60 µm are due The brittleness of the glass associated with this thickness is not suitable.

Die Breite des Flachglasbandes, welches kontinuierlich durch die Heizzone geführt wird, kann etwa 1 m betragen.The width of the flat glass ribbon, which is continuous through the heating zone can be about 1 m.

Nach dem erfindungsgemäßen Verfahren lassen sich auch Kunststoffscheiben beidseitig beschichten. Zu diesem Zwecke kann das einseitig beschichtete Band gewendet und nochmals durch die Anlage geschickt werden.Plastic disks can also be produced using the method according to the invention coat on both sides. For this purpose, the tape coated on one side can be turned and sent through the system again.

Ferner können nach dem erfindungsgemäßen Verfahren abwechselnde Lagen von Glas folien und Kunststoffschichten auf eine Kunststoffscheibe aufgebracht werden, so daß glasfolienverstärkte Kunststoffe hoher mechanischer Festigkeit erhalten werden können. Bei solchen verstärkten Kunststoffen entspricht die auf den Querschnitt bezogene Zugfestigkeit von Glasfolien etwa derjenigen von Glasfasern'gleicher Dicke. Der Vorteil derartiger, glasfolienverstärkter Kunststoffe be-.Furthermore, alternating layers can be made according to the method according to the invention of glass foils and plastic layers are applied to a plastic pane, so that glass film reinforced plastics of high mechanical strength are obtained can. In such reinforced plastics, it corresponds to the cross section related tensile strength of glass films approximately that of glass fibers of the same thickness. The advantage of such, glass film reinforced plastics.

steht darin, daß die hohe Festigkeit in allen Richtungen der Ebene der Glas folie vorliegt. Zu dem können gute optische Eigenschaften beibehalten werden, so daß dieses Material für bruchfeste Scheiben genutzt werden kann.stands in the fact that the high strength in all directions of the plane the glass foil is present. In addition, good optical properties can be retained, so that this material can be used for break-proof panes.

Die erfindungsgemäße Vorrichtung wird anhand beiliegender Zeichnungen näher erläutert. Es zeigen in schematischer Vereinfachung Figur 1 eine Anlage zur kontinuierlichen Herstellung und anschließendem Aufbringen von Glasfolie auf Kunststoffe und Figur 2 die Darstellung des Glasflusses.The device according to the invention is illustrated using the accompanying drawings explained in more detail. It show in schematic simplification figure 1 a plant for the continuous production and subsequent application of Glass foil on plastics and FIG. 2 the representation of the glass flow.

Aus Figur 1 geht hervor, daß ein Flachglas 1 mit Hilfe von angegetriebenen Gummiwalzen, deren Drehzahl genau einstellbar ist, in vertikaler Richtung in eine Heizstrecke 3 geführt wird. In dieserHeizstrecke ist eine Heizung 4 zum Vorheizen der Glasscheibe und anschließend daran eine Vorrichtung 5 zum Aufheizen auf die Erweichungstemperatur des Glases vorgesehen. Die Erweichungszone 6 des Glases ist so dimensiöniert, daß das Flachglas nur in einer Breite von ca.From Figure 1 it can be seen that a flat glass 1 with the help of driven Rubber rollers, the speed of which is precisely adjustable, in a vertical direction Heating section 3 is performed. In this heating section there is a heater 4 for preheating the glass pane and then a device 5 for heating to the Softening temperature of the glass provided. The softening zone 6 of the glass is dimensioned so that the flat glass is only approx.

30 mm in den fließfähigen Zustand gebracht wird. Die Abziehgeschwindigkeit aus dieser Erweichungszone 6 wird durch Abzugswalzen 7 aus Gummi bewirkt, welche ebenfalls mit genauer Drehzahlregelung angetrieben werden. Anschließend an die Erweichungszone 6 ist ferner eine Kuhlatrecke 8 mit wassergekühlten Kupferplatten vorgesehen. Nach dem Verlassen der Heizzone wird die so ausgezogene Glasfolie 9 über Walze 10 in eine vertikale Richtung gebracht und durch Zwischenfügen eines Klebebandes 11 mittels Walzen 12 mit dem Kunststoffband 13 verbunden. Anschließend können ferner Randbeschneider 14 vorgesehen sein, durch welche die überstehenden Kanten der Glas folie entfernt werden.30 mm is brought into the flowable state. The peel speed from this softening zone 6 is effected by take-off rollers 7 made of rubber, which can also be driven with precise speed control. Subsequent to the softening zone 6, a Kuhlatrecke 8 is also provided with water-cooled copper plates. To After leaving the heating zone, the glass film 9 drawn out in this way is moved over roller 10 in brought a vertical direction and by interposing an adhesive tape 11 by means Rollers 12 are connected to the plastic belt 13. Then you can also use edge trimmers 14 may be provided, through which the protruding edges of the glass film removed will.

Aus Figur 2 wird deutlich, daß sich das Glasband 1 nach dem Abziehen aus der Erweichungszone 6 in der Breite etwas zusammenzieht, so daß die resultierende Glas folie 9 eine Randzone 15 mit einer größeren Dicke besitzt. Es werden daher in der Breite überstehende Glasfolien auf den Kunststoff aufgebracht und die verdicktenRandzonenim Anschluß daran durch den Randbeschneider 14 entfernt. Nach einem Ausführungsbeispiel des erfindungsgemäßen Verfahrens wird ein Flachglas von 2 mm Dicke mit einer Nachführgeschwindigkeit von etwa 5 mm/min in die Heizzone eingeführt. Bei einer Abzugsgeschwindigkeit von 2 m/min beträgt die Dicke der Glas folie 5 /um. Das Verhältnis Abzugsgeschwindigkeit zu Nachführgeschwindigkeit ist in diesem Beispiel 400.From Figure 2 it is clear that the glass ribbon 1 after peeling from the softening zone 6 contracts somewhat in width, so that the resulting Glass foil 9 has an edge zone 15 with a greater thickness. It will therefore Glass films protruding in width are applied to the plastic and the thickened edge zones in the Then removed by the edge trimmer 14. According to one embodiment of the method according to the invention is a flat glass of 2 mm thick introduced into the heating zone at a feed rate of about 5 mm / min. At a take-off speed of 2 m / min, the thickness of the glass film is 5 μm. The ratio of haul-off speed to tracking speed is in this example 400
