Description
Technisches GebietTechnical area
Die Erfindung betrifft Verbundglasscheiben, insbesondere Verbundsicherheitsgläser, zum Einsatz in Kraftfahrzeugen. Die Erfindung betrifft weiterhin den Aufbau von Verbundglasscheiben mit thermoplasten oder polymeren Zwischenschichten.The invention relates to laminated glass panes, in particular laminated safety glasses, for use in motor vehicles. The invention also relates to the construction of laminated glass panes with thermoplastic or polymeric intermediate layers.
Technischer HintergrundTechnical background
Verbundglasscheiben für Fahrzeugverglasungen weisen in der Regel eine Außenglasscheibe und eine Innenglasscheibe auf, die miteinander in einem Autoklavenprozess mithilfe von klebenden Zwischenschichten verbunden werden.Laminated glass panes for vehicle glazing usually have an outer glass pane and an inner glass pane, which are connected to one another in an autoclave process with the aid of adhesive intermediate layers.
Darüber hinaus können bei Fahrzeugverglasungen in die Verbundglasscheiben weiterhin funktionelle Flächenelemente eingebracht werden. Diese funktionellen Flächenelemente dienen beispielsweise dem Schutz vor IR-Licht, zur Ent- und Verspiegelung, zum Realisieren einer integrierten Abschattung, zum Integrieren von Bildschirmen oder OLEDs und dergleichen.In addition, functional surface elements can still be incorporated into the laminated glass panes in vehicle glazing. These functional surface elements are used, for example, to protect against IR light, for antireflection and mirroring, for implementing integrated shading, for integrating screens or OLEDs and the like.
Die funktionellen Flächenelemente werden dazu zwischen der Außenglasscheibe und der Innenglasscheibe gemeinsam mit den herkömmlichen Zwischenschichten eingelegt und in dem Autoklavenprozess zu einem Laminat verarbeitet.For this purpose, the functional surface elements are inserted between the outer glass pane and the inner glass pane together with the conventional intermediate layers and processed into a laminate in the autoclave process.
Die funktionellen Flächenelemente werden in der Regel aufgerollt bereitgestellt, so dass diese in der Regel bei der Herstellung der Scheiben auf Form zugeschnitten und in den zu laminierenden Stapel von Glasscheiben und Klebefolien eingelegt werden. The functional surface elements are usually provided rolled up, so that they are usually cut to shape during the manufacture of the panes and placed in the stack of glass panes and adhesive films to be laminated.
Die funktionellen Flächenelemente können auch als Platten, insbesondere formstarr und planar, bereitgestellt sein.The functional surface elements can also be provided as plates, in particular rigid and planar.
Fahrzeugverglasungen bei modernen Fahrzeugen sind in zwei Richtungen gekrümmt, insbesondere um Aerodynamik und Design zu verbessern. Während die herkömmlich verwendeten klebenden Zwischenschichten unter Temperatur und Druck des Autoklavenprozesses aufweichen und sich dadurch der gekrümmten Form anpassen, sind die im Wesentlichen plan oder gerollt vorliegenden funktionellen Flächenelemente starr und in der Regel wenig flexibel. Daher können sich die funktionellen Flächenelemente im Autoklavenprozesses aufwellen, wenn diese, eingelegt zwischen den Glasscheiben, in zwei Richtungen gebogen werden. Ein Verformen der funktionellen Flächenelemente ist nicht zulässig, da diese dadurch in ihrer Funktion beeinträchtigt werden. Dies gilt insbesondere für deren optischen Eigenschaften, Reflexions- und/oder Transmissionseigenschaften.Vehicle glazing in modern vehicles is curved in two directions, especially to improve aerodynamics and design. While the conventionally used adhesive intermediate layers soften under the temperature and pressure of the autoclave process and thereby adapt to the curved shape, the functional surface elements, which are essentially flat or rolled, are rigid and generally not very flexible. The functional surface elements can therefore curl up in the autoclave process if they are inserted between the glass panes and bent in two directions. Deforming the functional surface elements is not permitted, as this will impair their function. This applies in particular to their optical properties, reflection and / or transmission properties.
Es ist Aufgabe der vorliegenden Erfindung, eine verbesserte Einbettung von funktionellen Flächenelementen in eine Verbundglasscheibe zu ermöglichen, die die Funktionsbeeinträchtigungen aufgrund von Verformungen während des Laminierens des Autoklavenprozesses reduziert.The object of the present invention is to enable an improved embedding of functional surface elements in a laminated glass pane, which reduces the functional impairments due to deformations during the lamination of the autoclave process.
Offenbarung der ErfindungDisclosure of the invention
Diese Aufgabe wird durch die Verbundglasscheibe gemäß Anspruch 1 sowie durch das Verfahren zum Herstellen einer Verbundglasscheibe gemäß dem nebengeordneten Anspruch gelöst.This object is achieved by the laminated glass pane according to
Weitere Ausgestaltungen sind in den abhängigen Ansprüchen angegeben.Further refinements are given in the dependent claims.
Gemäß einem ersten Aspekt ist eine Verbundglasscheibe, insbesondere für eine Fahrzeugverglasung, vorgesehen, umfassend:
- - eine in zwei Flächenrichtungen gekrümmte Außenglasscheibe
- - eine in zwei Flächenrichtungen gekrümmte Innenglasscheibe;
- - Mindestens eine Stapelanordnung von mehreren thermoplasten oder polymeren Zwischenschichten, die auf der Außenglasscheibe und/oder der Innenglasscheibe angeordnet ist;
- - ein funktionelles Flächenelement, das auf der Stapelanordnung der mehreren Zwischenschichten angeordnet ist,
- - an outer glass pane curved in two surface directions
- an inner glass pane curved in two surface directions;
- - At least one stack arrangement of several thermoplastic or polymeric intermediate layers, which is arranged on the outer glass pane and / or the inner glass pane;
- - A functional surface element which is arranged on the stacked arrangement of the multiple intermediate layers,
Fahrzeugverglasungen von Fahrzeugen werden zusehends 3D-geformt, d. h. sie weisen Krümmungen in zwei Flächenrichtungen auf. Dies erfolgt zur Verbesserung der Aerodynamik und des Designs. In der Regel werden Verbundglasscheiben im Fahrzeugbereich eingesetzt, um einen ausreichenden Splitterschutz bei Unfällen zu gewährleisten. Diese werden in einem Autoklavenprozess mit einer Außenglasscheibe und einer Innenglasscheibe hergestellt, zwischen denen eine oder mehrere klebende Zwischenschichten angeordnet werden.Vehicle glazing for vehicles is increasingly being shaped in 3D, i. H. they have curvatures in two surface directions. This is done to improve aerodynamics and design. As a rule, laminated glass panes are used in the vehicle sector in order to ensure adequate protection against splinters in the event of an accident. These are manufactured in an autoclave process with an outer glass pane and an inner glass pane, between which one or more adhesive intermediate layers are arranged.
Während die als Klebefolien ausgebildeten Zwischenschichten eine ausreichende Flexibilität und Elastizität aufweisen, um sich beim Laminieren an die 3D-Form des Außen- und Innenglases anzupassen, gilt dies in der Regel nicht für funktionelle Flächenelemente, die ebenfalls in die Verbundglasscheibe eingebracht werden sollen. Derartige funktionellen Flächenelemente dienen anders als die Zwischenschichten optischen Zwecken, wie z. B. Schutz vor Infrarotstrahlung, zur Ent- und Verspiegelung, sowie zur Integration von Abschattungen oder können als aktive Elemente, wie z. B. als transparente Bildschirme oder OLEDs, ausgebildet sein.While the intermediate layers designed as adhesive films have sufficient flexibility and elasticity to adapt to the 3D shape of the outer and inner glass during lamination, this generally does not apply to functional surface elements that are also to be incorporated into the laminated glass pane. Such functional In contrast to the intermediate layers, surface elements are used for optical purposes, e.g. B. protection against infrared radiation, for anti-reflective and mirror-coating, as well as for the integration of shading or can be used as active elements, such as. B. be designed as transparent screens or OLEDs.
Diese funktionellen Flächenelemente können zwar häufig ihre Funktion bei Krümmung bezüglich einer Flächenrichtung beibehalten, jedoch führt eine Krümmung in zwei Flächenrichtungen dazu, dass die funktionellen Flächenelemente stellenweise gedehnt oder gestaucht werden, was in der Regel zu einer Verformung, einer Welligkeit und folglich zu einer Veränderung deren optischer bzw. optoelektronischer Eigenschaften führt.These functional surface elements can often retain their function when curved with respect to one surface direction, but a curvature in two surface directions leads to the functional surface elements being stretched or compressed in places, which usually leads to deformation, waviness and consequently to a change in them optical or optoelectronic properties leads.
Eine Idee der obigen Verbundglasscheibe besteht darin, zwischen der Außenglasscheibe und der Innenglasscheibe klebende Folien-Zwischenschichten in unterschiedlicher Form anzuordnen, so dass sich lokal unterschiedliche Stapelhöhen von Zwischenschichten ergeben und örtlich die Zwischenschichten unterschiedliche Dicken erhalten und dadurch eine Krümmung des Zwischenraums zwischen den Glasscheiben zur Anordnung des funktionellen Flächenelements ausgeglichen werden kann. Durch die Formgebung der Zwischenschichten kann daher ein Anordnungsraum zur Anordnung des funktionellen Flächenelements so gestaltet werden, dass dieser in maximal einer Flächenrichtung gekrümmt ist. Dies vermeidet ein Dehnen oder Stauchen von Bereichen der funktionalen Schicht, so dass die Funktionalität der funktionalen Schicht erhalten bleiben kann.One idea of the above laminated glass pane is to arrange adhesive film intermediate layers in different shapes between the outer glass pane and the inner glass pane, so that locally different stacking heights of intermediate layers result and locally the intermediate layers have different thicknesses and thus a curvature of the space between the glass panes for arrangement of the functional surface element can be compensated. Due to the shape of the intermediate layers, an arrangement space for the arrangement of the functional surface element can therefore be designed in such a way that it is curved in at most one surface direction. This avoids stretching or compressing areas of the functional layer, so that the functionality of the functional layer can be retained.
Weiterhin kann das stufenförmige Profil die Krümmung der Außenglasscheibe und/oder der Innenglasscheibe zumindest in einer Flächenrichtung so ausgleichen, dass das funktionelle Flächenelement zumindest bezüglich der entsprechenden Flächenrichtung geradlinig auf der Stapelanordnung der Zwischenschichten anordenbar ist, so dass nach dem Autoklavenprozess zur Verbindung der Außenglasscheibe und der Innenglasscheibe mithilfe der Zwischenschichten ein einschlussloses Verbinden der Stapelanordnung der Zwischenschichten und des Flächenelements gewährleistet wird.Furthermore, the step-shaped profile can compensate for the curvature of the outer glass pane and / or the inner glass pane at least in one surface direction so that the functional surface element can be arranged in a straight line on the stacking arrangement of the intermediate layers at least with regard to the corresponding surface direction, so that after the autoclave process to connect the outer glass pane and the Inner glass pane with the help of the intermediate layers, an inclusion-free connection of the stacking arrangement of the intermediate layers and the surface element is guaranteed.
Gemäß einer Ausführungsform können die Zwischenschichten ausgebildet sein, um in dem Autoklavenprozess aufzuweichen und die Außenglasscheibe und die Innenglasscheibe miteinander zu verkleben.According to one embodiment, the intermediate layers can be designed to soften in the autoclave process and to glue the outer glass pane and the inner glass pane to one another.
Es kann vorgesehen sein, dass das stufenförmige Profil so dimensioniert ist, dass im Autoklavenprozess die Ränder der Zwischenschichten des stufenförmigen Profils sich verformen und ein einschlussloses Verbinden des Flächenelements und der entsprechenden Außenglasscheibe bzw. der entsprechenden Innenglasscheibe mit den Zwischenschichten erfolgt.It can be provided that the step-shaped profile is dimensioned in such a way that the edges of the intermediate layers of the step-shaped profile deform in the autoclave process and the surface element and the corresponding outer glass pane or the corresponding inner glass pane are connected to the intermediate layers without inclusion.
Gemäß einem weiteren Aspekt ist ein Verfahren zum Herstellen einer Verbundglasscheibe, insbesondere für eine Fahrzeugverglasung, vorgesehen, mit folgenden Schritten:
- - Bereitstellen einer in zwei Flächenrichtungen gekrümmten Außenglasscheibe und einer in zwei Flächenrichtungen gekrümmten Innenglasscheibe;

- - Vorsehen mindestens einer Stapelanordnung von mehreren thermoplasten oder polymeren Zwischenschichten, wobei die Stapelanordnung der Zwischenschichten ein stufenförmiges Profil aufweist;

- - Verbinden der Außenglasscheibe, des funktionellen Flächenelements und der Innenglasscheibe, so dass zwischen dem funktionellen Flächenelement und der Außenglasscheibe und/oder der Innenglasscheibe die Stapelanordnung angeordnet ist.
- Providing an outer glass pane curved in two surface directions and an inner glass pane curved in two surface directions;

- Providing at least one stacked arrangement of several thermoplastic or polymeric intermediate layers, the stacked arrangement of the intermediate layers having a stepped profile;

- Connecting the outer glass pane, the functional surface element and the inner glass pane, so that the stacking arrangement is arranged between the functional surface element and the outer glass pane and / or the inner glass pane.
Weiterhin kann vorgesehen sein, dass die Stapelanordnung der mehreren Zwischenschichten vor dem Aufbringen auf der Außenglasscheibe und/oder auf der Innenglasscheibe und/oder auf dem funktionellen Flächenelement hergestellt wird.Furthermore, it can be provided that the stacking arrangement of the plurality of intermediate layers is produced prior to application on the outer glass pane and / or on the inner glass pane and / or on the functional surface element.
Gemäß einer Ausführungsform können zwei Stapelanordnungen der mehreren Zwischenschichten auf das funktionelle Flächenelement aufgebracht werden und vor dem Verbinden mit der Außenglasscheibe und der Innenglasscheibe zwischen diese eingelegt werden.According to one embodiment, two stack arrangements of the plurality of intermediate layers can be applied to the functional surface element and placed between them before connecting to the outer glass pane and the inner glass pane.
