The interlayer film or the colored sections have a transparency difference (delta D) of 20%. The completely or partially colored interlayer film comprises plasticizer-containing polyvinyl acetal, perylene pigments, UV-absorber, and colored and colorless sections, where 1-80% of a visible surface is colored and contains a mixture of plasticizer-containing polyvinyl acetal, perylene pigments and UV-absorber and 99-20% of the visible surface is colorless and contains a transparent mixture on the basis of plasticizer-containing polyvinyl acetal without perylene pigments. The interlayer film or the colored sections have a transparency difference (delta D) of 20% for near-infrared radiation with 880 nm less than the transparency for sunlight radiation on thermoluminescence with 380-780 nm.

Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft ganz oder teilweise gefärbte Folien für Verbundverglasungen, insbesondere Windschutzscheiben, die eine hohe Transparenz für IR-Strahlung aufweisen.The The present invention relates wholly or partially colored Films for laminated glazing, in particular windscreens, which have a high transparency for IR radiation.

Stand der TechnikState of the art

PVB-Folien als Zwischenschicht für Verbundverglasungen werden entweder transparent oder ganz oder teilweise eingefärbt angeboten. Insbesondere Zwischenschichtfolien für Kfz-Windschutzscheiben werden häufig teilgefärbt, d. h. mit einem so genannten Farbband oder Farbkeil im oberen Bereich der Scheibe ausgerüstet, um die Blendwirkung durch Sonnenstrahlung zu minimierenPVB films as an intermediate layer for composite glazing be either transparent or wholly or partially dyed offered. In particular, interlayer films for automotive windscreens are often partially colored, d. H. with one like that equipped ribbon or color wedge in the upper region of the disc, to minimize the glare from solar radiation

Bei gleichmäßig eingefärbten PVB-Folien wird das farbgebende Mittel (Pigment oder Farbstoff) vor der Extrusion der PVB-Masse zugesetzt. Bei der Herstellung von Folien mit Farbband wird üblicherweise ein transparenter Hauptstrom und ein eingefärbter Seitenstrom über zwei entsprechend dimensionierte Extruder im Extrusionswerkzeug zusammen geführt und koextrudiert. Verfahren dieser Art sind bekannt und z. B. in EP 0 111 678 B1 , US 4,316,868 oder US 4,476,075 offenbart.For evenly colored PVB films, the colorant (pigment or dye) is added to the PVB mass prior to extrusion. In the production of films with ribbon, a transparent main stream and a colored side stream is usually led together and coextruded via two appropriately dimensioned extruders in the extrusion die. Methods of this type are known and z. In EP 0 111 678 B1 . US 4,316,868 or US 4,476,075 disclosed.

Die üblicherweise verwendeten Farbstoffe oder Pigmente müssen eine ausreichende Löslichkeit oder Dispergierbarkeit im weichmacherhaltigen PVB-Harz besitzen und gleichzeitig eine ausreichende UV-Stabilität aufweisen. Als ausgezeichnet Lichtstabiles Pigment wird insbesondere Farbruß zur Pigmentierung des Farbbandes von PVB-Folie eingesetzt. In blau oder grau eingefärbten Farbbändern überwiegt die Menge an Ruß in der Gesamtpigmentmischung, da zur Einstellung der geforderten Dunkelheit, genauer eines niedrigen L-Wertes im L,a,b-System, die eigentlich farbbestimmenden Pigmente bzw. Farbstoffe mit einer großen Menge Farbruß kombiniert werden müssen.The usual used dyes or pigments must have sufficient Solubility or dispersibility in the plasticizer-containing PVB resin and at the same time have sufficient UV stability. As excellent light-stable pigment is in particular color soot Pigmentation of the ribbon of PVB film used. In blue or gray colored ribbons outweighs the amount of carbon black in the total pigment mixture because of the adjustment the required darkness, more precisely a low L value in the L, a, b system, the actually color-determining pigments or dyes be combined with a large amount of color black have to.

Nachteilig ist, dass Ruß auch bis weit in den NIR- bzw. IR-Bereich hinein absorbiert.adversely is that soot also far into the NIR or IR range absorbed into it.

Moderne Fahrzeuge sind häufig mit Sensoren ausgerüstet, die z. B. Regentropfen auf der Windschutzscheibe durch die Absorption von Wasser im NIR-Bereich detektieren und somit eine automatische Regelung der Scheibenwischfunktion erlauben. Ebenfalls existieren bereits Nachtsichtsysteme, deren wesentlicher Bestandteil im Infraroten arbeitende Videokameras sind. Diese Systeme haben gemeinsam, dass dabei die Windschutzscheibe und damit auch die darin eingebettete PVB-Folie im IR- oder NIR-Bereich transparent sein müssen.modern Vehicles are often equipped with sensors the z. B. Raindrops on the windshield by the absorption of water in the NIR range and thus an automatic Allow regulation of the windscreen wiper function. Also exist already night vision systems, their essential component in the infrared working video cameras are. These systems have in common that while the windshield and thus the embedded therein PVB film in the IR or NIR range must be transparent.

Die Abschwächung von NIR- und IR-Strahlung durch Absorption von in der PVB-Folie befindlichem Farbruß beeinträchtigt die Funktion solcher Sensoren erheblich. Somit kann die Verbundglasscheibe weder vollständig eingefärbt noch das sicherheitsrelevante Ausstattungsmerkmal „Farbband" als Blendschutz mit den o. g. Ausstattungsmerkmalen die einen NIR-Sensor benötigen, kombiniert werden.The Attenuation of NIR and IR radiation by absorption affected by color black present in the PVB film the function of such sensors considerably. Thus, the laminated glass pane can neither fully colored nor the security relevant Feature "ribbon" as anti-glare with the o. g. Equipment features that require an NIR sensor, be combined.

Ein technischer Ausweg wäre, einen Ausschnitt im Farbband herzustellen, der dann wieder mit klarer PVB-Folie ausgefüllt wird. Alternativ müssten die Pigmente nachträglich lokal gebleicht werden. Beide Varianten sind sehr aufwendig.One technical solution would be to make a cutout in the ribbon, which is then filled again with clear PVB film. alternative would have the pigments subsequently bleached locally become. Both variants are very expensive.

Aufgabetask

Aufgabe der vorliegenden Erfindung war es daher, ganz oder teilweise gefärbte Zwischenschichtfolien für Verbundverglasungen bereit zu stellen, die einerseits eine ausreichende Absorption von Licht im UV/VIS-Bereich und andererseits eine hohe IR-/NIR-Transparenz aufweisen.task The present invention was therefore wholly or partially colored Interlayer films for composite glazing ready On the one hand, there is sufficient absorption of light in the UV / VIS range and on the other hand have high IR / NIR transparency.

Darstellung der ErfindungPresentation of the invention

Farbstoffe mit einer guten Absorption im sichtbaren Bereich des Sonnenlichts und einer gleichzeitig geringen Absorption im IR-/NIR-Bereich sind bekannt. So offenbart DE 102004007382 A1 die Verwendung von Perylenderivaten zur Einfärbung von Polymermassen wie Polyvinylalkohol oder Polyvinylbutyralen. Die Verwendung dieser Mischungen für Verbundverglasungen ist DE 10 2004 007 382 A1 nicht zu entnehmen.Dyes with a good absorption in the visible range of sunlight and a simultaneously low absorption in the IR / NIR range are known. So revealed DE 102004007382 A1 the use of perylene derivatives for coloring polymer compositions such as polyvinyl alcohol or polyvinyl butyrals. The use of these mixtures for composite glazing is DE 10 2004 007 382 A1 not to be taken.

Gegenstand der vorliegenden Erfindung sind daher ganz oder teilweise gefärbte Zwischenschichtfolien für Verbundverglasungen, enthaltend weichmacherhaltiges Polyvinylacetal, Perylenpigmente und UV-Absorber bzw. die aus mindestens zwei Glasscheiben mit mindestens einer solchen Zwischenschichtfolie hergestellten Verbundverglasungen oder Windschutzscheiben für Kraftfahrzeuge oder Flugzeuge.The present invention therefore wholly or partially colored Zwischenschichtfoli for composite glazings containing plasticizer-containing polyvinyl acetal, perylene pigments and UV absorbers or the composite glazings or windshields for motor vehicles or aircraft produced from at least two glass panes with at least one such interlayer film.

Erfindungsgemäße Zwischenschichtfolien, Verbundglaslaminate oder Windschutzscheiben weisen bevorzugt eine Differenztransparenz ΔD der Transparenz für NIR-Strahlung bei 880 nm abzüglich der Transparenz für Sonnenlichtstahlung TL bei 380–780 nm von mindestens 20%, bevorzugt von mindestens 30%, insbesondere von mindestens 50% auf, wobei die Obergrenze der Differenztransparenz ΔD 100% beträgt. Die Messungen der jeweiligen Transparenzen wird gemäß EN KCO durchgeführt.invention Interlayer films, laminated glass laminates or windshields preferably have a differential transparency ΔD of transparency for NIR radiation at 880 nm minus the transparency for sunlight directing TL at 380-780 nm from at least 20%, preferably at least 30%, in particular at least 50%, with the upper limit of the difference transparency ΔD 100%. The measurements of the respective transparencies is carried out according to EN KCO.

Die zur Herstellung von erfindungsgemäßen Folien eingesetzten Perylenpigmente sind mit vielen Substitutionsmustern z. B. aus DE 102004007382 A1 bekannt und werden als Lackzusatz und Farbstoff für Polymere eingesetzt. Bekannteste Vertreter dieser Stoffgruppe sind N,N'-Dimethylperylendicarbonsäurediimid (MPTCDI) oder Perylentetracarbonsäuredianhydrid (PTCDA), die kommerziell als LUMOGEN BLACK FK 4280 und LUMOGEN BLACK FK 4281 von der BASF AG erhältlich sind.The perylene pigments used for the production of films according to the invention are with many substitution patterns z. B. off DE 102004007382 A1 known and used as a paint additive and dye for polymers. Known representatives of this group of substances are N, N'-dimethylperylenedicarboxylic acid diimide (MPTCDI) or perylenetetracarboxylic dianhydride (PTCDA), which are commercially available as LUMOGEN BLACK FK 4280 and LUMOGEN BLACK FK 4281 from BASF AG.

Natürlich können solche NIR-transparenten Schwarzpigmente auch in Kombination mit als NIR- und IR-Filter wirkenden Nanopartikeln bzw. Pigmenten bzw. entsprechenden Gläsern kombiniert werden, so dass gegebenenfalls nur in einem engen Wellenlängenfenster, welches für die Funktion des Sensors maßgeblich ist, die Transparenz erhalten bleibt, im übrigen Wärmestrahlung im NIR- und IR-Bereich jedoch nicht durch das Verbundglas dringt. Dies ist insbesondere bei der Verwendung der erfindungsgemäßen Folien für Windschutzscheiben von Bedeutung, da so das Aufheizen des Fahrzeuginnenraums vermindert wird.Naturally Such NIR-transparent black pigments can also be used in Combination with nanoparticles acting as NIR and IR filters Pigments or corresponding glasses are combined, so that optionally only in a narrow wavelength window, which is decisive for the function of the sensor, the transparency is retained, otherwise heat radiation However, in the NIR and IR range does not penetrate through the laminated glass. This is especially true when using the invention Films for windshields of importance, since so the Heating the vehicle interior is reduced.

Zur Einstellung eines bestimmten Farbtones und der gewünschten Lichttransmission im sichtbaren Bereich können die NIR-transparenten Perylenpigmente mit weiteren Farbstoffen oder Pigmenten kombiniert werden.to Setting a specific color tone and the desired Visible light transmission can be the NIR transparent Perylene pigments are combined with other dyes or pigments.

Beispiele für diesen Zweck einsetzbare organische Farbstoffe sind z. B. Farbstoffe der Typenreihe Macrolex® der Firma Bayer, welche u. A. Anthrachinonabkömmlinge umfasst, oder Farbstoffe der Typenreihe Waxoline® der Firma Zeneca Colours, welche u. A. Chinolinabkömmlinge umfasst. Geeignete organische Pigmente sind z. B. Quinacridone oder Phthalocyanine verschiedener Hersteller. Als Beispiel für ein anorganisches Pigment sei neben den gängigen Metalloxidabkömmlingen Farbruß genannt, sofern dieser in solch kleiner Menge verwendet wird, dass eine ausreichend hohe Transmission im NIR-Bereich bzw. der bevorzugten Differenztransparenz ΔD erhalten bleibt. Weitere, geeignete Pigmente oder Farbstoffe sind eine oder mehrere Verbindungen der Gruppe Chinophthalone, Pyrazolone, Anthrachinone, Perinone, Monoazofarbstoffe, Phthalocyanine, Perylene, Azopigmente, Cromophtale, Thioindigopigmente, Dioxazine, Diketopyrrolopyrrole, Benzimidazolone, Isoindoline, Indanthrone, Metalloxide, -sulfide, -chromate und Kohlenstoff (Ruß).Examples of organic dyes which can be used for this purpose are, for example, B. dyes of the type series Macrolex ® the company Bayer, which u. A. Anthrachinonabkömmlinge includes, or dyes of the type series Waxoline ® Zeneca Colors, which u. A. Chinolinabkömmlinge includes. Suitable organic pigments are, for. As quinacridones or phthalocyanines from different manufacturers.
