Description

Composite panel, method for manufacturing the same and use of the same
The present invention relates to a composite panel, a method of manufacturing the composite panel and use of the composite panel.
A composite panel with a masking strip is known from WO 2014/174308 a 1. The masking strip extends in a peripheral region of the plate and is made of an opaque ceramic ink applied to the plate. However, in the case of surface coating of glass, it is difficult or impossible to apply the ceramic to the glass plate. Furthermore, in the production of composite glass, if separate pressure devices are provided for the plates of the composite plate, this leads to an increase in costs and thus to an increase in costs.
DE 19927683C 1 discloses a composite glass pane composed of at least two glass panes and a transparent composite layer connecting them and having a sunscreen layer which substantially reflects solar radiation, in particular infrared radiation, except for radiation in the visible spectrum. The composite pane has a further transparent coating (low-E layer) which is substantially reflective for thermal radiation and is spatially separated from the sun protection layer on its surface facing the interior space.
As is known, glazings, such as those used in sunroofs and sliding skylights, require a light transmission of 2% to 10%, and certain sunshades, which are characterized by a TTS value, which is a measure of the total solar thermal radiation transmitted through the panel and is measured, for example, according to ISO 9050. At a higher light transmission, on the one hand, too much heat radiation is transmitted and, on the other hand, the person behind the glazing may be visually disturbed due to too much light entering. At a lower light transmission, the glazing as a whole is too dark, so that a person behind the glazing can no longer see through it.
From WO 2017/103032 a1 a composite panel is known, which comprises an outer panel having an outer side surface and an inner side surface, an inner panel having an outer side surface and an inner side surface, and a thermoplastic intermediate layer connecting the inner side surface of the outer panel with the outer side surface of the inner panel. The composite pane has at least one sun protection coating between the outer pane and the inner pane, which sun protection coating substantially reflects or absorbs radiation of the solar radiation outside the visible spectrum, in particular infrared radiation, and wherein the composite pane has a coating reflecting thermal radiation on the inner side surface of the inner pane. The composite plate has a transmission index A of 0.02 to 0.08, wherein the transmission index A (A value) is determined according to the following formula (I): a ═ TLComposite glass plate/（TLLow E-coated panels* TE）（I），
Where TL is the light transmission and TE is the energy transfer rate measured according to ISO 9050 respectively.
Windshields in which a sun visor in the form of a functional element having electrically controllable optical properties, in particular electrically controllable transmission or scattering properties, is integrated are also known, for example, from WO 2019/166155 a 1. The driver can thus control the transmission properties of the windscreen itself with respect to solar radiation, and the conventional mechanical sun visor can be dispensed with. This makes it possible to reduce the weight of the vehicle and to obtain space in the roof region. Furthermore, electrical control of the sun visor is more convenient for the driver than manually turning down a mechanical sun visor. Such a windscreen may also be provided with an image pick-up area. In such areas, it is necessary to avoid bending of the glass sheet that may be caused by the application of the ceramic tape to the glass sheet.
Electrically controllable sun visors are also used in glass roofs of motor vehicles. Especially in the case of large-area panoramic glass panels, it is necessary to variably control the transmission of the panels. In this case, depending on the position of the sun, it is only necessary to shield a portion of the panel from light or to switch the entire area to opaque as a privacy protection in parking the vehicle.
Such a possible electrically switchable functional element for realizing a controllable sun visor is a so-called PDLC functional element (polymer dispersed liquid crystal). In this case, the active layer comprises a liquid crystal, which is embedded in a polymer matrix. If no voltage is applied, the liquid crystals are disorderly aligned, which causes strong scattering of light passing through the active layer. If a voltage is applied to the planar electrodes, the liquid crystals are aligned in a common direction and the transmission of light through the active layer is increased. PDLC functions work less by reducing the total transmission, but by increasing the scattering to ensure glare protection.
Windscreens with electrically controllable sun visors are known, for example, from DE 102013001334 a1, DE 102005049081B 3, DE 102005007427 a1 and DE 102007027296 a 1. DE 102010021563a1 describes a windshield with an electrically controllable sun visor which is switchable in partial regions, wherein the dimming of the individual elements can be controlled by capacitive sensor devices in the edge regions of the sun visor.
DE 202005014791U 1 discloses an interior lighting device for a motor vehicle. For this purpose, the OLED screen is designed as a light source, which radiates into the interior of the vehicle. The OLED screen can be arranged in particular in an interior ceiling of a motor vehicle, for example in a roof module. In this case, the roof module can be formed as a transparent or partially transparent roof module, wherein the OLED screen is transparent or partially transparent in the closed state, so that the roof module can be used as a transparent or partially transparent sunroof despite the provision of the OLED screen.
The electrical contacting of the electrically controllable functional elements is usually carried out by means of busbars (also called "busbars") which are applied to the planar electrodes in the edge regions of the functional elements and are in electrically conductive contact therewith. By connecting the busbar to an external voltage source, for example via a flat conductor mounted on the busbar, a voltage is applied to the planar electrode and the active layer of the functional element is switched.
US 2016/243796 a1 and DE 102011004500 a1 disclose laminated vehicle glazing having glass panes connected by a plastic layer, wherein the shaded region is created by printing on the plastic layer of the laminate.
The object of the present invention is to provide a composite panel having a masked area, which is compatible with at least one of the aforementioned coatings or functional elements (functional ä ten). Another object of the invention is to provide a cost-effective manufacturing method that can be easily used.
The composite panel according to the present invention comprises: a first plate having an outer side surface and an inner side surface; a second plate having an outer side surface and an inner side surface; and an intermediate layer, in particular a functional layer, which is arranged between the inner side surface of the first plate and the outer side surface of the second plate, wherein the second plate is designed as an inner plate, wherein the first plate is designed as an outer plate. The outer side is understood to mean the side of the first or outer plate and the inner side is understood to mean the side of the second or inner plate. Thus, when used as a vehicle glazing or a building glazing, the interior side is in the interior space of the vehicle or building.
Further, the composite panel includes a first polymer film disposed between the inside surface of the first panel and the intermediate layer and a second polymer film disposed between the outside surface of the second panel and the intermediate layer.
In the edge region of the composite plate, a printed opaque layer is applied on the first polymer film and/or the second polymer film.
The opaque layer printed on the polymer film is in particular an opaque enamel substitute layer, which is applied by means of a printing method. The opaque layer is in particular black and may comprise enamel.
The advantage of applying the first and/or second polymer film is that it can be produced more cost-effectively. In addition, it can also be used in combination with coated glass.
In one embodiment, a printed first opaque layer is applied on the first polymer film on the surface facing the intermediate layer or the surface facing the inside surface of the first plate.
In an alternative embodiment, a printed first opaque layer is applied to the inner side surface of the first plate. In this case, the printed opaque layer is in particular an enamel layer, which is also fired after the printing process.
The first opaque layer advantageously and thus preferably forms a circumferential edge of the composite plate. Optionally, the first opaque layer may have one or more stripes or patterns that are offset from the center of the composite panel.
In a further embodiment, a printed second opaque layer is applied on the second polymer film on the surface facing the intermediate layer or on the surface facing the outer side surface of the second plate.
The second opaque layer advantageously and thus preferably forms the peripheral edge of the composite panel. Optionally, the second opaque layer may have one or more stripes or patterns that are offset from the center of the composite panel.
The first opaque layer and/or the second opaque layer cover at least the electrically connected edge regions in which the intermediate layer formed as a functional layer is arranged.
The intermediate layer formed as a functional layer advantageously and therefore preferably comprises a liquid crystal layer, in particular a PDLC layer or an OLED layer, which is connected to at least one busbar at least along one side edge, in particular two opposite side edges. Contact at two opposite side edges is possible, for example, in the case of a rectangular or trapezoidal planar shape of the functional layer. The busbars serve for the electrical contacting of the functional layers.
The functional layer advantageously and therefore preferably also comprises a first and a second sealing layer. Such sealing layers are formed in particular from polymer films, in particular thermoplastic polymer films, for example polyethylene terephthalate (PET).
In one embodiment, a third and/or fourth polymer film is arranged adjacent to the intermediate layer, which is arranged at least in a part of the edge region. The third and/or fourth polymer film is in particular formed from a thermoplastic polymer film, for example PET.
In a further embodiment, a further polymer film or polymer intermediate layer is arranged between the first plate and the intermediate layer.
The composite plate advantageously and therefore preferably comprises a thickness compensator. Such thickness compensators are designed to compensate for the thickness of the functional layer and of the electrical connections, in particular of the busbars.
In a further embodiment, the first polymer film and/or the second polymer film and/or the further polymer film comprises polyvinyl butyral, ethylene vinyl acetate, polyurethane and/or mixtures and/or copolymers thereof, or is polyvinyl butyral (PVB).
In a further embodiment, the first and/or second plate is a colored or transparent glass or plastic plate, which is provided, in particular, with a coating that reflects thermal radiation.
Such coatings are known, for example, from WO2013/131667A 1. Coatings that reflect thermal radiation may also be referred to as low emissivity coatings, reduced emissivity coatings, low E coatings or low E layers. The task is to reflect thermal radiation, i.e. in particular IR radiation of a longer wavelength than the IR part of the solar radiation. At low external temperatures, the low E coating reflects heat back into the interior space and reduces cooling of the interior space. At high external temperatures, the low E coating reflects the thermal radiation of the heated composite panel outward and reduces heating of the interior space. On the inside of the inner panel, the coating according to the invention reduces the emission of thermal radiation of the panel into the interior space particularly effectively in summer and reduces the emission of thermal radiation into the external environment particularly effectively in winter.
The coating that reflects thermal radiation preferably comprises a functional layer that contains a Transparent Conductive Oxide (TCO), preferably indium tin oxide, tin oxide doped with antimony or fluorine, and/or zinc oxide doped with gallium and/or aluminum (ZnO: Ga, or ZnO: Al), of which indium tin oxide is preferred. However, the functional layer may also comprise other conductive oxides, for example fluorine-doped tin oxide (SnO)2F), antimony doped tin oxide (SnO)2Sb), indium zinc mixed oxide (IZO), gallium-doped or aluminum-doped zinc oxide, niobium-doped titanium oxide, cadmium stannate and/or zinc stannate. Particularly good results are thus obtained in terms of emissivity and bendability of the coating according to the invention. The refractive index of the material of the functional layer is preferably 1.7 to 2.5.
The heat-radiation-reflecting coating furthermore usually comprises a dielectric layer, in particular a dielectric layer formed from a dielectric oxide or nitride, such as ZnO, SnZnO, AlN, TiO2、SiO2Or Si3N4. The layer formed of reflective conductive oxide is anti-reflective above and below by using additional dielectric layers to ensure sufficiently low reflection at the inner side.
Alternatively or additionally, the first polymer film and/or the second polymer film has a polymer intermediate layer, which is or comprises, in particular, a coating that reflects thermal radiation.
The method according to the invention for manufacturing a composite panel according to the invention comprises:
providing the first and second sheets and the intermediate layer, in particular the functional layer
-printing a first opaque layer on the first polymer film or on the inner side surface of the first plate, and optionally subsequently firing, and/or
-printing a second opaque layer on the second polymer film,
-laminating the first sheet with the functional layer and the second sheet, wherein a first polymer film is arranged between the first sheet and the functional layer and a second polymer film is arranged between the second sheet and the functional layer.
If the opaque layer is printed only on the polymer film, the above method allows all of the films to be printed on the same printer and then combined together, thereby reducing manufacturing costs.
According to the invention, the composite panel according to the invention can be used as a vehicle glazing, in particular a sunroof, a windshield and/or a side window. Alternatively, the composite panel according to the invention can also be used in building glazing.

The intermediate layer 5 is designed as a functional layer 6. In the embodiment shown, it comprises a PDLC layer 30. Alternatively, however, designs as OLEDs or as combinations of these functional elements are also possible. The PDLC layer 30 is disposed in an interlayer comprised of two sealing layers, namely a first sealing layer 32 and a second sealing layer 34. In the vicinity of the functional layer 6 and in particular for electrical connection, there are also arranged busbars 36, by means of which the functional layer can be brought into at least two different states, namely transparent and translucent in the case of a PDLC layer or light-emitting and non-light-emitting in the case of an OLED. In the region of the busbar, a third polymer film 18 is arranged towards the two plates and a fourth polymer film 20 is arranged opposite.
