Definitions
- the invention relates to a method and a device for flood coating a polymeric material.
- Coating and painting in addition to the visual appearance, have a significant impact on the surface finish and durability of a polymeric material. This concerns both the visual impression as well as the color or gloss of the polymeric material, as well as its chemical and mechanical resistance. If the coating adheres poorly to the workpiece to be coated, the application of a permanently adhering lacquer can take place in a two-stage process.
- a primer is applied, which produces a chemical or physical bond between the polymeric workpiece and the topcoat.
- the functional layer can be applied.
- the functional layer and the primer can contain, in addition to colorants and pigments, UV blockers, preservatives and components for increasing the scratch resistance, for example nanoparticles.
- the primer applied first contains UV blockers and preservatives.
- the hardcoat is then applied on the primer in a second step.
- Hardcoats in many cases contain hybrid polysiloxanes which contain both Si-O groups and Si-R groups with organic radicals -R. These hardcoats have a high resistance to mechanical stress and aggressive chemical substances or compounds. This includes above all organic solvents but also dilute acids and bases.
- the application of the coating of primer and topcoat can be done by different methods. Common methods include brushing and rolling, spraying of aerosols, powder coating, dip coating and flood coating of solutions, emulsions or suspensions, as well as CVD (chemical vapor deposition) and PVD (physical vapor deposition) method from the gas phase. The methods differ significantly in terms of their equipment, the cost and especially for large quantities of their reproducibility.
- One common method of coating polymeric materials in large numbers is flood coating. For this purpose, a component is acted upon from the top edge with a liquid paint. The resulting coating can be done with one or more fixed flood or paint curtain or with a movable flood robot arm. The running paint wets the entire component depending on the position of the flood robot arm.
- a disadvantage of the flood coating is the physical layer thickness gradient from the point of the paint application or the upper tipping edge and the lower drip edge of the excess paint.
- Part of the solvent evaporates on the way over the component to be coated.
- the decrease in the solvent concentration leads in many cases to an increase in viscosity of the paint in the region of the drip edge.
- the increase in viscosity at the same time reduces the dripping speed and at the same time causes an increase in the layer thickness in the region of the drip edge.
- pre- and partially polymerized paint components can collect and accumulate in the area of the drip edge. In the tread area, the required layer thickness is often not reached, while at the drip edge, due to the subsequent flow of the paint, can build up too high a layer thickness.
- Too small a layer thickness can result in the loss of weathering stability and thus rapid aging of the coated component. In contrast, too high a layer thickness of the paint often causes stress cracking. This effect is intensified when several paint or functional layers are applied to the workpiece to be coated.
- the DE 199 06 247 A1 discloses a method for producing a two-layer topcoat on motor vehicle bodies.
- a transparent topcoat layer of a clearcoat coating is applied to a waterborne basecoat.
- the GB 1,097,461 A discloses a method of printing and dyeing plastic pages or films.
- the paint can be applied by brushing, spraying or flood coating and then optionally fixed by drying.
- the GB 1,201,292 A discloses an acrylic varnish for wood, glass, plastic and plastic body parts which can be cured at low temperatures.
- the acrylic paint can be applied by spraying, dipping, brushing or flood coating.
- the GB 2 123 841 A discloses a thin, scratch-resistant polyurethane coating which can be applied to the material via dip and flood coating techniques.
- Possible substrates include transparent polycarbonates and thermoplastic polyurethane slices.

- the layer thickness gradient of the coating from the upper inflow edge to the lower drip edge should be as low as possible.
- the inventive method for flood coating a polymeric material comprises a first step, wherein at least one component is inserted at an angle of 25 ° to 90 ° to the ground in a holder.

- the paint is applied from a movable nozzle arm on the component.
- the paint is subjected to an air flow below the upper edge of the component.
- below the upper edge in the context of the invention includes 30% of the surface of the component adjacent to the edge.
- the application of the air flow of at least portions within the range below the upper edge increases the evaporation of the solvent in the paint and increases the viscosity of the paint.
- the increased viscosity slows the flow of the paint in the area below the upper edge and equalizes the layer thickness of the paint below the upper edge of the layer thickness of the paint on the lower drip edge.
- At least one component is inserted in a holder at an angle of 25 ° to 90 ° to the ground in a first step. Subsequently, the component is heated at an upper edge to a temperature of 25 ° C to 100 ° C and during and / or subsequently coated from the upper edge with a lacquer.
- the term "upper edge” refers to 30% of the edge-adjacent surface of the component. The heating of the upper edge can be done with a hot air stream or blower. An alternative possibility is the Heating with the help of radiant heat, for example with an infrared radiator.
- the heating of the component below the upper edge increases, as with the application of an air flow, the evaporation of the solvent in the paint and increases the viscosity of the paint.
- the increased viscosity slows the flow of the paint in the area below the upper edge and equalizes the layer thickness of the paint below the upper edge (tipping edge) to the layer thickness of the paint at the lower drip edge.
- the two described embodiments of the method according to the invention can also be repeated in an automated process.

Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Flutbeschichtung eines polymeren Werkstoffes.The invention relates to a method and a device for flood coating a polymeric material.
Beschichtung und Lackierung hat neben dem optischen Aussehen einen wesentlichen Einfluss auf die Oberflächenbeschaffenheit und Beständigkeit eines polymeren Werkstoffes. Dies betrifft sowohl den optischen Eindruck wie die Farbe oder Glanz des polymeren Werkstoffes, als auch seine chemische und mechanische Beständigkeit. Haftet die Lackierung nur schlecht auf dem zu beschichtenden Werkstück, so kann die Auftragung eines permanent haftenden Lackes in einem zweistufigen Prozess erfolgen. In einem ersten Schritt wird ein Primer aufgetragen, welcher eine chemische oder physikalische Bindung zwischen dem polymeren Werkstück und dem Decklack herstellt. Nach dem Auftragen und Aushärten des Primers kann die Funktionsschicht aufgetragen werden. Die Funktionsschicht und der Primer können neben farbgebenden Verbindungen und Pigmenten auch UV-Blocker, Konservierungsstoffe sowie Komponenten zur Erhöhung der Kratzfestigkeit, beispielsweise Nanopartikel enthalten. In vielen Fällen enthält der zuerst aufgetragene Primer UV-Blocker und Konservierungsstoffe. Auf dem Primer wird dann in einem zweiten Schritt der Hardcoat aufgetragen. Hardcoats enthalten in vielen Fällen hybride Polysiloxane, welche sowohl Si-O Gruppen als auch Si-R Gruppen mit organischen Resten -R enthalten. Diese Hardcoats weisen eine hohe Beständigkeit gegenüber mechanischer Belastung und aggressiven chemischen Substanzen oder Verbindungen auf. Dies schließt vor allem organische Lösemittel aber auch verdünnte Säuren und Basen mit ein.Coating and painting, in addition to the visual appearance, have a significant impact on the surface finish and durability of a polymeric material. This concerns both the visual impression as well as the color or gloss of the polymeric material, as well as its chemical and mechanical resistance. If the coating adheres poorly to the workpiece to be coated, the application of a permanently adhering lacquer can take place in a two-stage process. In a first step, a primer is applied, which produces a chemical or physical bond between the polymeric workpiece and the topcoat. After application and curing of the primer, the functional layer can be applied. The functional layer and the primer can contain, in addition to colorants and pigments, UV blockers, preservatives and components for increasing the scratch resistance, for example nanoparticles. In many cases, the primer applied first contains UV blockers and preservatives. The hardcoat is then applied on the primer in a second step. Hardcoats in many cases contain hybrid polysiloxanes which contain both Si-O groups and Si-R groups with organic radicals -R. These hardcoats have a high resistance to mechanical stress and aggressive chemical substances or compounds. This includes above all organic solvents but also dilute acids and bases.
Die Auftragung der Lackierung aus Primer und Topcoat kann über verschieden Verfahren erfolgen. Gebräuchliche Verfahren beinhalten Streichen und Rollen, Aufsprühen von Aerosolen, Pulverbeschichtung, Tauchlackierung und Flutbeschichtung von Lösungen, Emulsionen oder Suspensionen, sowie CVD (chemical vapor deposition) und PVD (physical vapor deposition) Verfahren aus der Gasphase. Die Verfahren unterscheiden sich dabei deutlich in ihrem apparativen Aufwand, den Kosten und insbesondere bei großen Stückzahlen ihrer Reproduzierbarkeit. Ein geläufiges Verfahren zur Lackierung von polymeren Werkstoffen in großen Stückzahlen ist die Flutbeschichtung. Dazu wird ein Bauteil von der Oberkante an mit einem flüssigen Lack beaufschlagt. Die resultierende Beschichtung kann mit einer oder mehreren fest montierten Flutdüsen oder Lackvorhang oder mit einem beweglichen Flutroboterarm erfolgen. Der ablaufende Lack benetzt dabei in Abhängigkeit von der Position des Flutroboterarms das gesamte Bauteil.The application of the coating of primer and topcoat can be done by different methods. Common methods include brushing and rolling, spraying of aerosols, powder coating, dip coating and flood coating of solutions, emulsions or suspensions, as well as CVD (chemical vapor deposition) and PVD (physical vapor deposition) method from the gas phase. The methods differ significantly in terms of their equipment, the cost and especially for large quantities of their reproducibility. One common method of coating polymeric materials in large numbers is flood coating. For this purpose, a component is acted upon from the top edge with a liquid paint. The resulting coating can be done with one or more fixed flood or paint curtain or with a movable flood robot arm. The running paint wets the entire component depending on the position of the flood robot arm.
Ein Nachteil der Flutbeschichtung ist der physikalisch bedingte Schichtdickengradient von dem Punkt der Lackauftragung oder der oberen Anflutkante und der unteren Abtropfkante der überschüssigen Lackierung. Auf dem Weg über das zu beschichtende Bauteil verdunstet ein Teil des Lösemittels. Die Abnahme der Lösungsmittelkonzentration führt in vielen Fällen zu einer Viskositätszunahme des Lacks im Bereich der Abtropfkante. Die Zunahme der Viskosität verringert gleichzeitig die Abtropfgeschwindigkeit und bedingt gleichzeitig eine Zunahme der Schichtdicke im Bereich der Abtropfkante. Zudem können sich im Bereich der Abtropfkante vor- und teilpolymerisierte Lackanteile sammeln und anstauen. Im Anflutbereich wird die geforderte Schichtdicke häufig nicht erreicht, während sich an der Abtropfkante, bedingt durch das Nachfließen des Lackes, eine zu hohe Schichtdicke aufbauen kann. Eine zu geringe Schichtdicke kann den Verlust der Witterungsstabilität und damit eine schnelle Alterung des beschichteten Bauteils zur Folge haben. Im Gegensatz dazu bewirkt eine zu hohe Schichtdicke des Lackes häufig eine Spannungsrissbildung. Dieser Effekt verstärkt sich, wenn mehrere Lack- oder Funktionsschichten auf dem zu beschichtenden Werkstück aufgetragen werden.A disadvantage of the flood coating is the physical layer thickness gradient from the point of the paint application or the upper tipping edge and the lower drip edge of the excess paint. Part of the solvent evaporates on the way over the component to be coated. The decrease in the solvent concentration leads in many cases to an increase in viscosity of the paint in the region of the drip edge. The increase in viscosity at the same time reduces the dripping speed and at the same time causes an increase in the layer thickness in the region of the drip edge. In addition, pre- and partially polymerized paint components can collect and accumulate in the area of the drip edge. In the tread area, the required layer thickness is often not reached, while at the drip edge, due to the subsequent flow of the paint, can build up too high a layer thickness. Too small a layer thickness can result in the loss of weathering stability and thus rapid aging of the coated component. In contrast, too high a layer thickness of the paint often causes stress cracking. This effect is intensified when several paint or functional layers are applied to the workpiece to be coated.

Die Aufgabe der Erfindung liegt darin, ein Verfahren zur Flutbeschichtung eines polymeren Werkstoffes bereitzustellen, welches auf dem zu beschichtenden Bauteil eine gleichmäßige Schichtdicke der aufgetragen Lackschichten ermöglicht. Insbesondere der Schichtdickengradient der Lackierung von der oberen Anflutkante zu der unteren Abtropfkante sollte so gering wie möglich ausfallen.The object of the invention is to provide a method for flood coating a polymeric material, which on the component to be coated uniform Layer thickness of the applied paint layers allows. In particular, the layer thickness gradient of the coating from the upper inflow edge to the lower drip edge should be as low as possible.
Die Aufgabe der vorliegenden Erfindung wird erfindungsgemäß durch ein Verfahren zur Flutbeschichtung eines polymeren Werkstoffes gemäß Anspruch 1 gelöst. Bevorzugte Ausführungen gehen aus den Unteransprüchen hervor.The object of the present invention is achieved by a method for flood coating a polymeric material according to
Eine erfindungsgemäße Vorrichtung zur Flutbeschichtung und deren Verwendung gehen aus weiteren nebengeordneten Ansprüchen hervor.An inventive device for flood coating and their use will become apparent from further independent claims.
Das erfindungsgemäße Verfahren zur Flutbeschichtung eines polymeren Werkstoffes umfasst einem ersten Schritt, wobei mindestens ein Bauteil mit einem Winkel von 25° bis 90° zum Boden in eine Halterung eingelegt wird. Das Bauteil wird anschließend von einer oberen Kante an mit einem Lack beschichtet. Der Lack fließt von der oberen Kante über das Bauteil bis zur Abtropfkante. In der Abhängigkeit von der Größe des zu beschichtenden Bauteils fließt der Lack aus einem Lackvorhang und/oder aus mehreren nebeneinander angeordneten Düsen auf das Bauteil. In einer weiteren Möglichkeit wird der Lack aus einem beweglichen Düsenarm auf das Bauteil aufgebracht. Gleichzeitig und/oder während der Lack auf das Bauteil fließt, wird der Lack unterhalb der oberen Kante des Bauteils mit einem Luftstrom beaufschlagt. Der Ausdruck "unterhalb der obere Kante" schließt im Sinne der Erfindung 30 % der an die Kante angrenzenden Oberfläche des Bauteils mit ein. Die Beaufschlagung mit dem Luftstrom von zumindest Teilbereichen innerhalb des Bereiches unterhalb der oberen Kante erhöht die Verdunstung der im Lack befindlichen Lösemittel und erhöht die Viskosität des Lackes. Die erhöhte Viskosität verlangsamt das Abfließen des Lackes im Bereich unterhalb der oberen Kante und gleicht die Schichtdicke des Lackes unterhalb der oberen Kante an die Schichtdicke des Lackes an der unteren Abtropfkante an.The inventive method for flood coating a polymeric material comprises a first step, wherein at least one component is inserted at an angle of 25 ° to 90 ° to the ground in a holder. The component is then coated from an upper edge with a paint. The paint flows from the upper edge over the component to the drip edge. As a function of the size of the component to be coated, the paint flows from a paint curtain and / or from a plurality of juxtaposed nozzles onto the component. In another possibility, the paint is applied from a movable nozzle arm on the component. At the same time and / or while the paint flows onto the component, the paint is subjected to an air flow below the upper edge of the component. The term "below the upper edge" in the context of the invention includes 30% of the surface of the component adjacent to the edge. The application of the air flow of at least portions within the range below the upper edge increases the evaporation of the solvent in the paint and increases the viscosity of the paint. The increased viscosity slows the flow of the paint in the area below the upper edge and equalizes the layer thickness of the paint below the upper edge of the layer thickness of the paint on the lower drip edge.
In einer alternativen Ausgestaltung des erfindungsgemäßen Verfahrens zur Flutbeschichtung eines polymeren Werkstoffes wird in einem ersten Schritt mindestens ein Bauteil mit einem Winkel von 25° bis 90° zum Boden in eine Halterung eingelegt. Anschließend wird das Bauteil an einer oberen Kante auf eine Temperatur von 25 °C bis 100 °C erwärmt und währenddessen und/oder anschließend von der oberen Kante an mit einem Lack beschichtet. Der Ausdruck "oberen Kante" bezieht sich wie oben beschrieben auf 30 % der an die Kante angrenzenden Oberfläche des Bauteils. Die Erwärmung der oberen Kante kann mit einem heißen Luftstrom oder -Gebläse erfolgen. Eine alternative Möglichkeit ist die Erwärmung mit Hilfe von Strahlungswärme, beispielsweise mit einem Infrarotstrahler. Die Erwärmung des Bauteils unterhalb der oberen Kante erhöht, wie bei der Beaufschlagung mit einem Luftstrom, die Verdunstung der im Lack befindlichen Lösemittel und erhöht die Viskosität des Lackes. Die erhöhte Viskosität verlangsamt das Abfließen des Lackes im Bereich unterhalb der oberen Kante und gleicht die Schichtdicke des Lackes unterhalb der oberen Kante (Anflutkante) an die Schichtdicke des Lackes an der unteren Abtropfkante an.In an alternative embodiment of the method according to the invention for flood coating a polymeric material, at least one component is inserted in a holder at an angle of 25 ° to 90 ° to the ground in a first step. Subsequently, the component is heated at an upper edge to a temperature of 25 ° C to 100 ° C and during and / or subsequently coated from the upper edge with a lacquer. As used hereinabove, the term "upper edge" refers to 30% of the edge-adjacent surface of the component. The heating of the upper edge can be done with a hot air stream or blower. An alternative possibility is the Heating with the help of radiant heat, for example with an infrared radiator. The heating of the component below the upper edge increases, as with the application of an air flow, the evaporation of the solvent in the paint and increases the viscosity of the paint. The increased viscosity slows the flow of the paint in the area below the upper edge and equalizes the layer thickness of the paint below the upper edge (tipping edge) to the layer thickness of the paint at the lower drip edge.
Die beiden beschriebenen Ausgestaltungen des erfindungsgemäßen Verfahrens können auch in einem automatisierten Prozess wiederholt werden. Die Wiederholung der Lackauftragung sowie die Beaufschlagung mit einem Luftstrom oder die Erwärmung des Bauteils ermöglichen die Abscheidung von mehreren gleichen und/oder verschiedenen Lackschichten. Die Wiederholung kann sowohl an derselben Vorrichtung als auch an durch ein Laufband miteinander verbundenen verschiedenen erfindungsgemäßen Vorrichtungen erfolgen.The two described embodiments of the method according to the invention can also be repeated in an automated process. The repetition of the paint application and the application of an air stream or the heating of the component allow the deposition of several identical and / or different paint layers. The repetition can take place both on the same device and on different devices according to the invention connected to each other by a treadmill.

Die Halterung enthält bevorzugt Metalle und/oder Legierungen, besonders bevorzugt Eisen, Aluminium, Chrom, Vanadium, Nickel, Molybdän, Mangan oder Polymere wie Polyethylen, Polypropylen, Polystyrol, Polyurethane, Polycarbonate, Polymethylmetacrylate, Polyacrylate, Polyester, Polyamide und/oder Gemische oder Copolymere davonThe component is preferably inserted at an angle of 35 ° to 70 °, more preferably 40 ° to 60 ° to the ground in the holder.
