Kunststoffe nehmen im Automobilbau inzwischen einen Anteil zwischen 15 und 20 Gewichtsprozent mit steigender Tendenz ein. Dabei handelt es sich häufig um Exterieur- und Interieurteile, die ihre entsprechenden optischen, haptischen und funktionalen Eigenschaften durch eine Lackierung erhalten. Die steigenden Anforderungen an Qualität und Wirtschaftlichkeit sowie Ressourceneffizienz, aber auch der globale Wettbewerbsdrucks erfordern immer wirtschaftlichere, nachhaltigere und flexiblere Lackierprozesse. So erfreut sich der Trend zu weniger Lackierschritten beispielsweise durch füllerlose Lacksysteme auch bei Anbauteilen aus Kunststoff großer Beliebtheit. Dabei reduziert sich durch den Wegfall der Zwischentrocknung der Energieverbrauch und gleichzeitig sinken Materialverbrauch und Lösemittelemissionen. Außerdem wird wenigerIn the meantime, plastics account for between 15 and 20 percent by weight and are increasing in automotive engineering. These are often exterior and interior parts, which receive their corresponding visual, haptic and functional properties through a paint job. The increasing demands on quality and efficiency as well as resource efficiency, but also the global competitive pressure, require ever more economical, more sustainable and more flexible painting processes. For example, the trend towards fewer coating steps, for example with filler-less coating systems, is also very popular with plastic attachments. The elimination of intermediate drying reduces energy consumption and at the same time reduces material consumption and solvent emissions. In addition, less

Entsprechende Lacklösungen gibt es unter anderem für glänzende, spritzgegossene Interieurteile, beispielsweise Zierleisten, aus einem ABS-PC-Blend (ABS: Acrylnitril- Butadien-Styrol , PC: Polycarbonat ) . Der Lack sorgt mit einem nur einschichtigen Lackaufbau für eine edle, hochglänzende Oberfläche . Corresponding paint solutions are available, inter alia, for glossy, injection-molded interior parts, for example trim strips, of an ABS-PC blend (ABS: acrylonitrile-butadiene-styrene, PC: polycarbonate). The varnish provides a noble, high-gloss surface with a single-layer varnish structure.
In der Automobilindustrie kommen bisher für die Beschichtung von Kunststoffen überwiegend lösemittelhaltige und wasserbasierte Lacke zum Einsatz. Lösemittelhaltige UV-Dual- Cure-Systeme werden ebenfalls seit einigen Jahren angewendet. Sie ermöglichen eine gute Mattierbarkeit sowie Metallic- Farbtöne. Allerdings lassen sich mit UV-Lacken nicht alle Metallic-Farbtöne herstellen. Hochglanzoberflächen werden mit lösemittelhaltigen UV-Dual-Cure-Klarlacken im Aufbau mit Basislacken erzeugt. Verstärkt zum Einsatz kommen in letzter Zeit für die KunstStofflackierung sowohl 100%-UV-Klarlacke mit Klavierlackoptik als auch 2K-Dual-Cure-Systeme, wobei Erstere deutlich höhere chemische Beständigkeitseigenschaften aufweisen. Auf vielen gängigen KunstStoffsubStraten wie ABS, SAN (Styrol-Acrylnitril) , PS (Polystyrol) und ABS/PC (Polycarbonat) werden gute Haftungswerte ohne Vorbehandlung erzielt. Ansonsten lassen sich die Haftungseigenschaften in der Regel durch eine Aktivierung der Oberfläche durch Beflammen, Plasmabehandlung oder Gasphasenfluorierung optimieren . In the automotive industry, mainly solvent-based and water-based paints are used for the coating of plastics. Solvent-based UV dual-cure systems have also been used for several years. They allow good matting and metallic shades. However, not all metallic shades can be produced with UV varnishes. High-gloss surfaces are produced with solvent-based UV dual-cure clearcoats in the structure with basecoats. Increasingly used for KunstStofflackierung are both 100% UV clearcoats with piano lacquer optics and 2K dual-cure systems, the former having significantly higher chemical resistance properties. On many common KunstStoffsubStraten such as ABS, SAN (styrene-acrylonitrile), PS (polystyrene) and ABS / PC (polycarbonate) good adhesion values are achieved without pretreatment. Otherwise, the adhesion properties in usually by activation of the surface by flaming, plasma treatment or gas phase fluorination optimize.

To provide plastic material part, in which the number of painting steps and the cost of the paint shop is reduced and at the same time meet the quality requirements for the paint.
Eine weitere Aufgabe der Erfindung besteht in der Bereitstellung einer entsprechenden Beschichtungsvorrichtung und einem durch das Verfahren erhaltenen beschichteten Kunststoffbauteil . Another object of the invention is to provide a corresponding coating apparatus and a coated plastic component obtained by the method.

Mit Blick auf den Stand der Technik war es überraschend und für den Fachmann nicht vorhersehbar, dass die Aufgabe, die der vorliegenden Erfindung zugrundelag, mit Hilfe des erfindungsgemäßen Verfahrens gelöst werden konnte. Ein besonderer Vorteil der Erfindung besteht nämlich darin, dass in dem vorgeschlagenen Verfahren gänzlich auf den Schritt einer Aktivierung des Substrats verzichtet wird. With regard to the prior art, it was surprising and unforeseeable for the skilled worker that the object on which the present invention was based could be achieved with the aid of the method according to the invention. Namely, a particular advantage of the invention is that in the proposed method, the step of activating the substrate is entirely dispensed with.
Damit entfallen nicht nur Investitionskosten für die Aktivierungseinheiten beim Um- oder Aufrüsten bestehender Lackieranlagen, sondern auch die mit denThis eliminates not only investment costs for the activation units when converting or upgrading existing paint shops, but also with the
Aktivierungseinheiten (Beflammung, Plasma) verbundenen Brandschutzmaßnahmen und Betriebskosten. DasActivation units (flame treatment, plasma) associated fire protection measures and operating costs. The
KunstStoffSubstrat aus Polyethylen (PE) , Polypropylen (PP) , oder thermoplastische Polyolefinen (TPO) kann gefüllt oder ungefüllt sein. Polyethylene (PE), polypropylene (PP), or thermoplastic polyolefin (TPO) plastic substrate may be filled or unfilled.
Auf den KunstStoffsubStraten aus Polyethylen (PE) , Polypropylen (PP) , oder thermoplastische Polyolefinen (TPO) können so ohne Aktivierung Ein-, Zwei, undOn the synthetic textile substrates made of polyethylene (PE), polypropylene (PP), or thermoplastic polyolefins (TPO), one-, two-, and one-half can be activated without activation
Dreischichtaufbauten aus Dual-Cure, 2K- oder 1K-Systemen bereitgestellt werden, die den Anforderungen der Automobilhersteller, beispielsweise für lackierte Interieur¬ kunstStoffbauteile aus Polypropylen, genügen. Three-layer structures made of dual-cure, 2K or 1K systems are provided, which meet the requirements of automobile manufacturers, for example, for painted interior ¬ KunstStoffbauteile polypropylene.
Bevorzugt enthält dabei das erste Beschichtungsmittel in Schritt b wenigstens einen 1K- oder 2K- Hydroprimer oder einen Lösemittelprimer und/oder UV-2K-Dualcure-Primer . Bevorzugt enthält das zweite Beschichtungsmittel einen Hydrolack, vorzugsweise wenigstens einen UV-2K-Dualcure- Hydrolack . In this case, the first coating agent in step b preferably contains at least one 1K or 2K hydroprimer or a solvent primer and / or UV-2K dual-cure primer. Preferably, the second coating composition contains a hydrosol, preferably at least one UV-2K Dualcure hydro lacquer.
Die Verfahrenskombination aus 1K oder 2K-Lösemittel- und/oder Hydroprimer und/oder UV/2K-Dualcureprimer mit UV/ 2K-Dualcure Hydrolacksystemen auf Substraten aus PP und TPO kann dabei im Verbund mit ABS, ABS mod. PC, PC ABS, PC, PMMA für lackierte Interieurbauteile erfolgen. Eine Aktivierungseinheit, z.B. mit Beflammung oder Plasma ist nicht erforderlich. The combination of 1K or 2K solvent and / or hydroprimer and / or UV / 2K dualcure primer with UV / 2K Dualcure hydro lacquer systems on substrates of PP and TPO can in combination with ABS, ABS mod. PC, PC ABS, PC, PMMA for painted interior components. An activation unit, e.g. with flame or plasma is not required.
Das Verfahren unter Verwendung von UV/2K-Dualcure Hydrolacken ermöglicht vorteilhaft die Herstellung mattierter und hochkratzfester Lacksysteme mit Dekor-, Soft- und Comforthaptik für lackierte In- erieurbauteile . The process using UV / 2K Dualcure hydro lacquers makes it possible to produce matt and highly scratch-resistant lacquer systems with decorative, soft and comfort haptics for lacquered interior components.
Ein weiterer Vorteil eines derart beschichteten KunstStoffbauteils liegt u.a. in seiner Parfümbeständigkeit, z.B. gegen ätherische Öle und in seinem weichen Haptikcharakter . Another advantage of such coated KunstStoffbauteils u.a. in its perfume resistance, e.g. against essential oils and in its soft feel.
Die Verfahrenskombination aus UV/2K-Hydro-Dualcure Klarlacke mit 1K oder 2K-Lösemittel- und Hydroprimer und/oder 2K- Basislacken und/oder UV/2K-Dualcure Hydrolacksystemen ermöglicht zudem die Generierung einer breiten Produktpallette mit matten, seidenglänzenden oder hochglänzenden Oberflächen. The combination of UV / 2K-Hydro-Dualcure clearcoats with 1K or 2K-solvent and hydroprimer and / or 2K-basecoats and / or UV / 2K-Dualcure hydro lacquer systems also enables the generation of a wide product range with matt, semi-glossy or high-gloss surfaces.
Die Oberfläche des Substrats bzw. Kunststoffs wird vor dem Auftragen des ersten Beschichtungsmittels erfindungsgemäß nicht aktiviert. Die herkömmliche Aktivierung von KunstStoffsubStraten mittels Beflammung, Plasmaverfahren, die in Niederdruck- und Atmosphärendurckplasmen unterschieden werden, undThe surface of the substrate or plastic is not activated according to the invention before the application of the first coating agent. The conventional activation of KunstoffoffsubStraten by means of flame treatment, plasma processes, which are distinguished in low-pressure and atmospheric return plasmas, and
Gasphasenfluorierung lässt sich vor allem für die Abreinigung dünner organischer Verunreinigungen bei gleichzeitiger Aktivierung der Oberfläche einsetzen. Diese Doppelfunktion basiert auf einer physikalischen und chemischen Reaktion des Verfahrens. Dadurch wird neben einer sauberen Oberfläche auch die Erhöhung der Oberflächenspannung bzw. Oberflächenenergie erzielt, um optimale Voraussetzungen für den nachfolgenden Lackierprozess zu schaffen. Gas phase fluorination can be used primarily for the cleaning of thin organic contaminants with simultaneous activation of the surface. This dual function is based on a physical and chemical reaction of the process. As a result, in addition to a clean surface, the increase of the surface tension or surface energy is achieved in order to create optimum conditions for the subsequent painting process.
Angesichts des erfindungsgemäßen Verfahrens scheint jedoch für die Haftfestigkeit auf den genannten KunstStoffsubStraten die gleichzeitige Schwächung der KunstStoffOberfläche durch den Energieeintrag bei der Aktivierung genauso entscheidend zu sein und wird bisher kaum beachtet. Analytische Untersuchungen der Aktivierungseffekte zielen meist auf die Art und den Anteil der erzeugten polaren funktionellen Gruppen sowie die dadurch erzielte Polarität, lassen aber nachteilige Abbaueffekte außer Acht. However, in view of the method according to the invention, the simultaneous weakening of the KunstStoff surface by the energy input during the activation seems to be just as decisive for the adhesive strength on the mentioned KunstStoffsubStraten and is hitherto hardly considered. Analytical studies of the activation effects usually aim at the type and proportion of polar functional groups generated and the polarity achieved thereby, but disregard adverse degradation effects.
Bei PE-, PP-, bzw. TPO-Werkstoffen, die für einen Polymerabbau anfällig sind, scheint es beispielsweise so zu sein, dass auf eine Aktivierung verzichtet werden kann, um eine sichere Haftfestigkeit wasserbasierender Lacksysteme zu ermöglichen, ohne dass die nachteilige Wirkung eines potentiellen Polymerabbaus aufgrund einer Aktivierung eintritt . With PE, PP or TPO materials that are susceptible to polymer degradation, for example, it appears that activation can be dispensed with in order to ensure reliable adhesion of water-based coating systems, without the disadvantageous effect of a potential polymer degradation due to activation occurs.
Unbehandeltes PP zeigt in der XPS-AnalyseUntreated PP shows in the XPS analysis
(Photoelektronenspektroskopie) reine -C-C Anteile von 91,25%, keine -COOH Anteile. Beim Beflammen und bei ADP-Verfahren (Atmosphärendruckplasmaverfahren über Düse) steigen insbesondere die Carboxylgruppenanteile (-COOH) sehr stark an. Mit 2K-Systemen erfolgen über die Härtung bekannte Isocyanatnebenreaktionen in Richtung Biureth- und Harnstoffgruppen . (Photoelectron spectroscopy) pure -CC content of 91.25%, no -COOH content. Flaming and ADP procedures (Atmospheric pressure plasma method via nozzle), in particular the carboxyl groups (-COOH) increase very strongly. With 2K systems, known isocyanate side reactions take place in the direction of biurethane and urea groups via curing.
Mit ToF-SIMS (Sekundärionenmassenspektrometrie) werden derartige Oberflächenspecies nachweisbar, wobei sich dann Unterschiede zum unbehandelten PP zeigen. Die Charakterisierung und Nachweisführung erfolgt demnach mit gekoppelten Analysen von XPS und ToF-SIMS. With ToF-SIMS (secondary ion mass spectrometry) such surface species are detectable, which then show differences to the untreated PP. The characterization and verification is carried out with coupled analyzes of XPS and ToF-SIMS.

Die folgenden Beispiele zeigen tabellarisch verschiedene Lackauf auten bestehend aus Hydro-Grundierung als erstem Beschichtungsmittel und Basislack bzw. Schutzlack als zweitem Beschichtungsmittel auf geflammten und ungeflämmten Substraten. Die Beschichtungen weisen allgemein eine 1K- Grundierung mit UV-Dualcure Decklack oder eine 1K-Grundierung mit 2K-Decklack oder UV-Hydro-Dualcure Decklacke auf. The following examples show, in tabular form, various paint vehicles consisting of hydro-primer as the first coating agent and basecoat or protective paint as the second coating agent on flamed and non-marred substrates. The coatings generally have a 1K Primer with UV Dualcure Topcoat or a 1K Primer with 2K Topcoat or UV Hydro-Dualcure Topcoats.
Anschließend erfolgt eine lacktechnische Prüfung auf Kratzfestigkeit und Cremeeinflüsse. This is followed by a paint inspection for scratch resistance and cream influences.
Unbehandeltes PP als Substrat zeigt bei alleiniger Verwendung von 1K-, 2K-, etc. Hydrolacken mangelhafte Untergrundhaftung, wobei sich die Beschichtungen komplett vom Untergrund abziehen lassen. Lösemittelhaltige Lacke haften ohne Vorbehandlung ebenfalls schlechter. DieUntreated PP as a substrate shows the sole use of 1K-, 2K-, etc. Hydro lacquers insufficient underground adhesion, whereby the coatings can be completely removed from the substrate. Solvent-based paints also adhere less well without pretreatment. The
Gitterschnittprüfungen ergeben hierbei Kennwerte > GT 3 - GT 5 (sehr schlechte Haftfestigkeit) für Hydrolacke auf PP ohne Aktivierung. Die erfindungsgemäßen Lackaufbauten zeigen dagegen bei den Gitterschnittprüfungen Kennwerte < GT 1 - GT 0 (sehr gute Haftfestigkeit) . Ferner kommen zur Charakterisierung der Lackhaftung Analysemethoden wie beispielsweise DSC (Differential Scanning Calorimetrie) und Prüfungen der Kratzfestigkeit (z.B. Vickers Eindringhärte) , Nutzung allgemeiner Oberflächenanalytik, wie IR-Spektroskopie, XPS und ToF-SIMS, wie oben beschrieben, in Betracht . Cross-hatch tests result in characteristic values> GT 3 - GT 5 (very poor adhesion) for hydro lacquers on PP without activation. On the other hand, the coating compositions according to the invention show characteristic values <GT 1 - GT 0 (very good adhesive strength) in cross-hatch tests. Furthermore, for the characterization of the paint adhesion analysis methods such as DSC (differential scanning calorimetry) and tests of scratch resistance (eg Vickers penetration hardness), use of general surface analysis, such as IR spectroscopy, XPS and ToF-SIMS, as described above, into consideration.

Fig. 1 zeigt zwei Lackiervorrichtungen aus dem Stand der Technik für Interieurbauteile aus Acrylnitril-Butadien-Styrol (ABS) Copolymerisat , ABS-modifiziertes Polycarbonat (PC) , Polycarbonat (PC) , Polymethylmethacrylat (PMMA) oder Mischungen daraus, im Nass/Nass Prozess, d.h. ohne Zwischentrocknung (Fig. 1 a) im Trockner 8, oder mit Zwischentrocknung nach Grundierung in der ersten Lackierkabine 6 (1 b) . 1 shows two prior art coating devices for interior components of acrylonitrile-butadiene-styrene (ABS) copolymer, ABS-modified polycarbonate (PC), polycarbonate (PC), polymethylmethacrylate (PMMA) or mixtures thereof, in the wet / wet process ie without intermediate drying (FIG. 1 a) in the dryer 8, or with intermediate drying after priming in the first painting booth 6 (FIG. 1 b).
In dieser üblichen Prozessfolge wird gemäß Fig. la der Dekorsoftlack in zwei Aufträgen nass in nass aufgebracht. Es erfolgt keine Zwischentrocknung, sondern lediglich ein Flash- Off für 7-10 Min bei 20° - 26°C und 55±5% relativer Feuchte. In this conventional process sequence, according to FIG. 1a, the decorative soft lacquer is applied wet in wet in two applications. There is no interim drying, but only a flash off for 7-10 min at 20 ° - 26 ° C and 55 ± 5% relative humidity.
In der ersten Lackierkabine 6 wird ein Primer mit oder ohne Zwischentrocknung zur Grundierung aufgetragen. In der zweiten Lackierkabine 11 erfolgt die Auftragung von 2K-Hydro-Decklack für Interieurfarben, Dekor, Soft und Effektlacke wie Metallic, Silber, Chrom, etc. In the first painting booth 6, a primer with or without intermediate drying is applied to the primer. In the second paint booth 11, the application of 2K Hydro Topcoat for interior paints, decor, soft and effect paints such as metallic, silver, chrome, etc. takes place.
In beiden Fällen erfolgt eine alkalische Nassreinigung 1 als Äquivalent für zwei Entfettungszonen in zwei Spülzonen sowie anschließendem Spülen mit VE- (vollentsalztem) Wasser. Daran schließt sich eine Blaszone 2 mit einem Haftwassertrockner 3 an. Üblicherweise ist bei Kunststoffbauteilen, die nicht aus Acrylnitril-Butadien-Styrol (ABS) Copolymerisat , ABS- modifiziertes Polycarbonat (PC) , Polycarbonat (PC) , Polymethylmethacrylat (PMMA) oder Mischungen daraus hergestellt sind, nach dem Haftwassertrockner 3 eine Aktivierungseinrichtung (nicht dargestellt) vorgesehen. Es folgt ein Durchfahrbereich 5 vor der ersten 6 und zweiten 11 Lackierkabine. Vor dem Durchfahrbereich 5 zur ersten Lackierkabine 6 befindet sich eine erste Kühlzone 4. In both cases, an alkaline wet cleaning 1 is equivalent to two degreasing zones in two rinse zones as well then rinse with demineralised water. This is followed by a blowing zone 2 with an adhesive water dryer 3. Usually, in plastic components which are not made of acrylonitrile-butadiene-styrene (ABS) copolymer, ABS-modified polycarbonate (PC), polycarbonate (PC), polymethyl methacrylate (PMMA) or mixtures thereof, after the adhesive water dryer 3 an activation device (not shown ) intended. This is followed by a drive-through area 5 in front of the first 6 and second 11 spray booth. Before the drive-through area 5 to the first painting booth 6 is a first cooling zone. 4
Beim üblichen Verfahren zum Zweischichtaufbau werden nun zwei Dekorsoftlacke nass in nass in der ersten 6 und zweiten 11 Lackierkabine aufgebracht, wobei zwischen den Lackierkabinen eine Kontrollzone 10 angeordnet ist, in der auch der Flash- Off stattfindet. Der zweiten Lackierkabine ist eine Abdunstzone 12 mit dem abschließenden Lacktrockner 13 angeordnet, in dem das vollständig beschichtete Substrat bei 80°C für 30 Min getrocknet wird. Nach Durchlaufen der abschließenden Kühlzone 14 gelangt das nunmehr lackierte Bauteil in den Ausfahrbereich 15 und weiterhin in die Teileabnahmekontrolle 17, sowie der Teileaufgabe 18 und dem Bestückungsbereich 19. In the conventional method for two-layer construction, two Dekorsoftlacke be wet in wet in the first 6 and second 11 spray booth applied, between the spray booths a control zone 10 is arranged, in which the flash off takes place. The second paint booth is a Abdunstzone 12 arranged with the final paint drier 13, in which the fully coated substrate is dried at 80 ° C for 30 min. After passing through the final cooling zone 14, the now painted component arrives in the extension area 15 and also in the parts removal control 17, as well as the parts task 18 and the placement area 19.
In der Prozessfolge gemäß Fig. lb wird der Dekorsoftlack in zwei Aufträgen im Primer-Trockner 8, dem eine Abdunstzone 7 vorgeschaltet ist, nach Grundierung in der ersten Lackierkabine 6 (1 b) zwischengetrocknet. Auch hier ist zwischen den Lackierkabinen eine Kontrollzone 10 angeordnet, in der auch der Flash-Off stattfindet. Der zweiten Lackierkabine ist eine Abdunstzone 12 mit dem abschließenden Lacktrockner 13 nachgeschaltet, in dem das vollständig beschichtete Substrat bei 80°C für 30 Min getrocknet wird. Nach Durchlaufen der abschließenden Kühlzone 14 gelangt das nunmehr lackierte Bauteil in den Ausfahrbereich 15 und weiterhin in die Teileabnahmekontrolle 17, sowie der Teileaufgabe 18 und dem Bestückungsbereich 19. In the process sequence according to FIG. 1b, the decorative soft lacquer is intermediately dried in two jobs in the primer dryer 8, which is preceded by an evaporation zone 7, after priming in the first painting booth 6 (FIG. 1 b). Here, too, a control zone 10 is arranged between the paint booths, in which the flash-off takes place. The second spray booth is a Abdunstzone 12 with the final Paint drier 13 downstream, in which the fully coated substrate is dried at 80 ° C for 30 min. After passing through the final cooling zone 14, the now painted component arrives in the extension area 15 and also in the parts removal control 17, as well as the parts task 18 and the placement area 19.
Für PP-/TPO-Substrate sind im Stand der Technik keine Direktlackierungen ohne Aktivierung möglich. Auch für den Einsatz wässriger Primer ist derzeit eine Aktivierung zwingend erforderlich. Die nachfolgend beschriebenen Lackieranlagen stellen eine vorrichtungsseitige Lösung dieses Problems dar. For PP / TPO substrates, no direct coatings without activation are possible in the prior art. Activation is also currently required for the use of aqueous primers. The painting systems described below represent a device-side solution to this problem.
Fig. 2 zeigt eine schematische Darstellung einer erfindungsgemäßen Lackiervorrichtung für Kunststoffbauteile, insbesondere Interieurbauteile, enthaltend Polyethylen (PE) , Polypropylen (PP) , thermoplastischen Polyolefinen (TPO) oder Mischungen daraus im Nass/Nass-Prozess . Es erfolgt keine Zwischentrocknung 8, sondern lediglich ein Flash-Off für 7-10 Min bei 20° - 26°C und 55±5% relativer Feuchte. 2 shows a schematic representation of a coating device according to the invention for plastic components, in particular interior components containing polyethylene (PE), polypropylene (PP), thermoplastic polyolefins (TPO) or mixtures thereof in the wet / wet process. There is no intermediate drying 8, but only a flash-off for 7-10 min at 20 ° - 26 ° C and 55 ± 5% relative humidity.
Als Substrate werden PP, TPO ohne Aktivierung, gegebenenfalls in Verbindung mit ABS, ABS mod., PC ABS, PC oder PMMA verwendet. Die Verfahrenskombination aus 1K oder 2K- Lösemittel- und/oder Hydroprimer und/oder UV/2K- Dualcureprimer mit UV/ 2K-Dualcure Hydrolacksystemen auf Substraten aus PP und TPO kann, auch im Verbund mit ABS, ABS mod. PC, PC ABS, PC, PMMA für sämtliche lackierten Interieurbauteile erfolgen. Eine aufwändige und kostenintensive Aktivierungseinheit, z.B. mit Beflammung oder Plasma ist nicht erforderlich. Damit entfallen nicht nur Investitionskosten für die Aktivierungseinheiten beim Um- oder Aufrüsten bestehender Lackieranlagen, sondern auch die mit den Aktivierungseinheiten (Beflammung, Plasma) verbundenen Brandschutzmaßnahmen und Betriebskosten. The substrates used are PP, TPO without activation, optionally in combination with ABS, ABS mod., PC ABS, PC or PMMA. The combination of 1K or 2K solvent and / or hydroprimer and / or UV / 2K dualcure primer with UV / 2K Dualcure hydro lacquer systems on substrates of PP and TPO can, also in combination with ABS, ABS mod. PC, PC ABS, PC, PMMA for all painted interior components. A complex and expensive activation unit, eg with flame or plasma is not required. This not only eliminates Investment costs for the activation units when retrofitting or upgrading existing paint shops, but also the fire protection measures and operating costs associated with the activation units (flame treatment, plasma).
Auch bei den erfindungsgemäßen UV-Hydro Dualcure- Lackaufbauten kann der Lackierprozess grundsätzlich "nass in nass" (Fig. 2) oder mit Zwischentrocknung im Primer-Trockner 8 (Fig. 3) der haftvermittelnden Schicht erfolgen. Zusätzlich erfolgt ein Flash-Off für 7-10 Min bei 24° - 26°C und 55±5% relativer Feuchte. In the case of the UV-Hydro Dualcure lacquer constructions according to the invention, the lacquering process can in principle also be carried out "wet on wet" (FIG. 2) or with intermediate drying in the primer dryer 8 (FIG. 3) of the adhesion-promoting layer. In addition, a flash-off for 7-10 minutes at 24 ° - 26 ° C and 55 ± 5% relative humidity.
Im Unterschied zur Anlage gemäß Fig. 1 a,b wird nunmehr die haftvermittelnde UV/2K Dualcure-Hydroprimer/Grundierung oder ein 2K-Hydroprimer in der ersten Lackierkabine 6 aufgetragen. In contrast to the system according to FIGS. 1 a, b, the adhesion-promoting UV / 2K dual-cure hydroprimer / primer or a 2K hydroprimer is now applied in the first painting booth 6.
In der zweiten Lackierkabine 11 erfolgt der Auftrag der UV/2K Dualcure - Hydrobasislacke für Interieurfarben, Dekor, Soft und Effektlacke wie Metallic, Silber, Chrom, etc. In the second paint booth 11, the UV / 2K Dualcure - Hydrobase paints are applied for interior paints, decor, soft and effect paints such as metallic, silver, chrome, etc.
Vorrichtungsseitig weisen die erfindungsgemäßen Vorrichtungen gegenüber dem Stand der Technik zusätzlich eine UV- Strahlereinheit 16 auf, welche bevorzugt im Anlagenbereich zwischen der abschließenden Kühlzone 14 und dem Ausfahrbereich 15 angeordnet ist. On the device side, the devices according to the invention additionally have a UV radiator unit 16 compared to the prior art, which is preferably arranged in the system area between the final cooling zone 14 and the extension area 15.
