Description
Die Erfindung betrifft eine Vorrichtung zur optischen und messtechnischen Ermittlung der Mikrofaltungskinetik sowie der Faltungsgeschwindigkeit von Oberflächen dekorativer und funktioneller elektronenstrahl- oder UV-härtender Farb- und Lackbeschichtungen, ausgelöst durch kurzwellige monochromatische Excimer-UV-Strahlung, im Real-Time-Modus.The invention relates to a device for optical and metrological determination of the Mikaltaltungskinetik and the folding speed of surfaces of decorative and functional electron beam or UV-curing paint and lacquer coatings, triggered by short-wavelength monochromatic excimer UV radiation, in real-time mode.
Gemäß des Standes der Technik wird die zu behandelnde Farb- oder Klarlackoberfläche mit nahezu monochromatischem kurzwelligem Excimer-UV-Licht, zum Beispiel der Wellenlängen 172 nm oder 222 nm, bestrahlt. Diese energiereichen Photonen sind in der Lage, in der aus reinen Monomeren oder Oligomeren oder einem Monomer/Oligomergemisch bestehenden auf ein Substrat aufgetragenen Nassschicht ohne Verwendung von Photoinitiator Polymerradikale zu erzeugen und eine Polymerisation auszulösen.According to the prior art, the color or clearcoat surface to be treated is irradiated with nearly monochromatic short-wave excimer UV light, for example the wavelengths 172 nm or 222 nm. These high-energy photons are able to generate polymer radicals in the wet layer applied to a substrate from pure monomers or oligomers or a monomer / oligomer mixture without the use of photoinitiator and to initiate a polymerization.
Die kurzwelligen UV-Photonen haben aber nur eine geringe Eindringtiefe in die Farb- und Lackschicht von je nach Wellenlänge einigen 100 nm bis einigen Mikrometern und härten diese demzufolge nur an deren Oberfläche und in den oberflächennahen Schichten, wenn die Beschichtung entsprechend dicker ist. Die dadurch entstehende Haut schwimmt dann noch auf einer flüssigen Schicht. Infolge von Schrumpfspannungen, die bei der Polymerisation dieser Haut entstehen, beginnt sich diese Haut zu Falten. Nach Beendigung des Faltungsprozesses wird die Gesamtschicht mit langwelligem UV-Licht oder mit Elektronenstrahlung ausgehärtet, so dass die Haut auf dem Untergrund fixiert wird und eine einheitliche Beschichtung mit strukturierter Oberfläche entsteht.However, the short-wave UV photons have only a small penetration depth into the paint and varnish layer of a few 100 nm to a few micrometers depending on the wavelength and consequently cure only on their surface and in the near-surface layers if the coating is correspondingly thicker. The resulting skin then floats on a liquid layer. As a result of shrinkage stresses that arise during the polymerization of this skin, this skin begins to wrinkle. After completion of the folding process, the entire layer is cured with long-wave UV light or with electron beam radiation, so that the skin is fixed to the substrate and a uniform coating with structured surface is formed.
Der photochemische Mikrofaltungsprozess kann aber auch durch die Nachhärtung in einem Zwischenstadium abgebrochen und damit die gerade erreichte Faltungsstruktur eingefroren werden.However, the photochemical microfolding process can also be terminated by the post-curing in an intermediate stage, thus freezing the just achieved folding structure.
Diese Form der Oberflächenstrukturierung von strahlenhärtbaren Farb- und Lackbeschichtungen unterschiedlichster Substrate hat inzwischen das Stadium der industriellen Anwendung erreicht. Hauptanwendung ist die Herstellung matter Oberflächen im Bereich von Möbeldekorfolien und -papieren sowie von Wandverkleidungen im Innen- und Außenbereich. Die nicht einfache Einstellung des Glanzgrades wurde zum Patent angemeldet –
Unter Verwendung von Nanokomposit-Lacken –
Schließlich werden durch die Mikrostrukturierung die Haft- und Gleitreibung im Vergleich zur glatten Oberfläche wesentlich verringert und mit der Lackformulierung und der Faltungsform können die Reibungseigenschaften eingestellt werden.Finally, microstructuring substantially reduces the static friction and sliding friction compared with the smooth surface and, with the paint formulation and the folding form, the frictional properties can be adjusted.
In speziellen Untersuchungen konnte auch die Mikrofaltbarkeit von aufgeschmolzenem UV-Pulverlack nachgewiesen werden.In special investigations, the microfoldability of molten UV powder coating could be detected.
Technisch wird der Prozess der photochemischen Mikrofaltung durch Verwendung einer Excimerlampe als Einzel-, Doppellampe oder Array, wie in den Schriften
Eine große Rolle spielt die Bestrahlungsdosis und dabei auch der Zeitpunkt der finalen Härtung, der bei definierter Durchlaufgeschwindigkeit vom Abstand zwischen der kurzwelligen Excimerlampe und dem Härtungsstrahler abhängt.A major role is played by the irradiation dose and, at the same time, the time of the final hardening, which depends on the distance between the short-wave excimer lamp and the curing radiator at a defined throughput speed.
In der Regel wird die Farb- oder Lackformulierung nach den anwendungstechnischen Ansprüchen zusammengestellt. Dabei kann, wenn bekannt, bereits das Mikrofaltungsverhalten der beteiligten Lackrohstoffkomponenten berücksichtigt werden.In general, the color or paint formulation is composed according to the application requirements. If known, the micro-folding behavior of the coating raw material components involved can already be taken into account.
Die sich tatsächlich einstellende Mikrofaltungsstruktur wird jedoch erst nach Beschichtung des Zielsubstrates mit beabsichtigter Schichtdicke des Lackes unter Anwendung des industriell vorgesehenen Beschichtungsverfahrens und nach Bestrahlung mit einer in
Für Versuche zur Anpassung der Mikrofaltungsstruktur, zum Beispiel zur Einstellung eines definierten Glanzgrades oder/und bestimmter Reibungskoeffizienten, kann die in
Nachteilig ist dabei nicht nur der mit Einschränkungen in der Anlagenvariabilität insbesondere des Abstandes der Strahler und der Bandgeschwindigkeit bei Probendurchlaufanlagen verbundene technische und damit finanzielle Aufwand, sondern auch der experimentelle Zeitaufwand, insbesondere bei Verwendung von Lackkomponenten bei denen das Faltungsverhalten noch unbekannt ist. Auch die Prüfung von UV-Pulverlacken, bei der die Beschichtung geschmolzen bei Temperaturen ≥ 100°C durch die Anlage gefahren werden muss, ist auf diese Weise nur sehr schwer möglich.The disadvantage here is not only the technical and therefore financial expense associated with limitations in the variability of the system, in particular the distance between the radiator and the belt speed in sample flow systems, but also the experimental time required, especially when using paint components in which the folding behavior is still unknown. Also, the testing of UV powder coatings, in which the coating must be melted at temperatures ≥ 100 ° C to drive through the system, is very difficult in this way possible.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung zur Ermittlung der Faltungskinetik und der Faltungsgeschwindigkeit von strahlenhärtbaren Lackrohstoffkomponenten sowie Farb- und Lacken vorzuschlagen, mit der die technologischen Prozesse wirklichkeitsnah simuliert und alle gewünschten Informationen schnell und unkompliziert erhalten werden können.The object of the present invention is therefore to propose a device for determining the folding kinetics and the folding speed of radiation-curable coating raw material components and paints and varnishes, with which the technological processes can be simulated realistically and all desired information can be obtained quickly and easily.
Die Lösung der erfindungsgemäßen Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Anspruches 1 in Zusammenhang mit den Merkmalen des Oberbegriffes. Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.The solution of the object according to the invention results from the characterizing features of
Die erfindungsgemäße Vorrichtung soll in Aufbau und Funktion nachfolgend anhand der
Für das Registrieren der Faltungskinetik ist es notwendig den Vorgang analog eines real-time FTIR-Gerätes in Echtzeit optisch und messtechnisch zu verfolgen und zur Ermittlung der Faltungsgeschwindigkeit auswertbar zu registrieren.For registering the folding kinetics, it is necessary to follow the process in real time optically and metrologically in a manner analogous to that of a real-time FTIR device and to evaluate the folding speed in an evaluable manner.

Für die Untersuchung des Mikrofaltungsverhaltens viskoser Formulierungen oder gar aufzuschmelzender UV-Pulverlacke dient eine optional einzusetzende elektrische Heizung des Probentisches.In this way, the time interval between the excimer irradiation and the final curing in an industrial plant can be readjusted, or the necessary distance for a defined production speed and a selected coating formulation can be determined or a folding state can be "frozen" in the course of the kinetics. For the investigation of the microfolding behavior of viscous formulations or even to be melted UV powder coatings is an optionally used electrical heating of the sample table.
