Abstract

A process (A) for drying paint on metallic or non-metallic parts or mounted assemblies of any structure, involves using a continuous or static system in a heated drying space, especially water- dilutable or solvent-containing 1- or 2-component epoxy- or polyurethane-based paint on aluminium components or on fibre composite components for aircraft. The drying space is heated by means of microwaves generated in a microwave module and conducted via waveguides with a defined outlet, and air is made to flow round the substrates in the room. Drying air contains a dipolar additive (I) in a predetermined controllable amount within the range of 20-90%, which is kept constant during the process. Also claimed is a process (B) in which the paint is treated with a polarisable dielectric as additive (II), this additive being used directly to increase the temperature of the paint film during microwave irradiation and/or to increase the temperature of the air/additive mixture by extraction from the paint into the surrounding air.

Description

Die Erfindung betrifft ein Verfahren zur Trocknung von Lacken auf metallischen oder nichtmetallischen Einzelteilen oder montierten Baugruppen beliebiger Struktur im Durchlaufverfahren bzw. im stationären Betrieb in einem erwärmten Trocknungsraum, insbesondere von Lachen auf Aluminiumbauteilen oder auf Bauteilen aus Faserverbundwerkstoffen für Luftfahrzeuge, wobei als Lacke vorzugsweise wasserverdünnbare wie auch lösemittelhaltige Ein- oder Zweikomponentenlacke auf Epoxyd- oder Polyurethanbasis verwendet werden.The invention relates to a method for drying paints on metallic or non-metallic parts or assembled assemblies of any structure in a continuous process or in stationary operation in a heated one Drying room, especially puddles on aluminum components or on components made of fiber composite materials for aircraft, preferably as water-borne varnishes as well as solvent-based one- or two-component paints be used on epoxy or polyurethane basis.

Eine Trocknung von auf metallischen Bauteilen oder Bauteilen aus Faserverbundwerkstoffen aufgebrachten Lachen, insbesondere von Zweikomponentenlacken, in Konvektionsöfen mittels warmer Luft innerhalb eines Temperaturbereiches von z. B. 40 bis 90 °C ist allgemein bekannt. Ebenso bekannt ist die Trocknung derartiger Lacke mit Hilfe von Infrarotstrahlung. Nachteile dieser Trocknungsverfahren sind in einem verhältnismäßig hohen Energieaufwand sowie in langen Trocknungszeiten zu sehen. Auch können nachteiligerweise mittels der Infrarotstrahlung wegen entstehender Schattenbildung lediglich Bauteile von einfacher geometrischer Gestalt getrocknet werden.Drying on metallic components or components pools made of fiber composite materials, in particular of two-component paints, in convection ovens by means of warm air within a temperature range of e.g. B. 40 to 90 ° C is generally known. The is also known Drying of such varnishes with the help of infrared radiation. Disadvantages of these drying processes are proportionate high energy consumption and in long drying times to see. Can also disadvantageously by means of infrared radiation due to the formation of shadows Components of simple geometric shape are dried.

In der "Deutsche Farben-Zeitschrift, 23. Jahrgang, Nr. 12, 1969" ist auf Seite 585 auf die Möglichkeit der Trocknung von Lachen mittels Mikrowellenstrahlen hingewiesen. Hierbei führt die Einwirkung von in kommerziell verfügbaren Anlagen erzeugten Mikrowellen in einem Bereich von 108 bis 1010 Hz zu einer Erwärmung von Filmmaterial, die im wesentlichen die Überführung in den festen Zustand bewirkt. Die Erwärmung erfolgt durch die auftretenden dielektrischen Verluste; sie ist hochwirksam und sofort einsetzend. Besonders geeignet sind Lacke, die Wasser als Lösungsmittel enthalten. Auch für Druckfarben ist die Mikrowellentrocknung im Prinzip anwendbar. Es ist zweifelhaft, ob Standard-Lacksysteme ohne besondere dielektrische Eigenschaften auf dem obigen Wege zu trocknen sind.The "Deutsche Farben-Zeitschrift, 23rd year, No. 12, 1969" on page 585 refers to the possibility of drying pools by means of microwave radiation. The action of microwaves produced in commercially available systems in a range from 10 8 to 10 10 Hz leads to heating of the film material, which essentially brings about the conversion into the solid state. The heating occurs due to the occurring dielectric losses; it is highly effective and starts immediately. Varnishes containing water as a solvent are particularly suitable. In principle, microwave drying can also be used for printing inks. It is doubtful whether standard coating systems without special dielectric properties can be dried in the above way.

Weiterhin ist es aus den "Patent Abstracts of Japan, C-1021, 1993, Vol. 17, No 46 JP 4-260472 A" bekannt, einen speziellen Lack zu verwenden, der ein durch Mikrowellen erwärmbares Pulver enthält. Die Erwärmung des Pulvers führt dann zur Trocknung des Lackfilmes, wobei die Harze des Lackes und die Substratwerkstoffe wärmebeständig sein müssen. Besondere Eigenschaften, die der Lack anscheinend besitzt, sind aber der Druckschrift nicht zu entnehmen.Furthermore, it is from the "Patent Abstracts of Japan, C-1021, 1993, Vol. 17, No 46 JP 4-260472 A ", a special To use varnish, which is a microwave heated Contains powder. The heating of the powder then leads to Drying the paint film, the resins of the paint and the Substrate materials must be heat-resistant. Special properties, that the paint apparently has, but they are Document cannot be removed.

In der FR 24 58 323 ist ein Verfahren zur Beschichtung eines Substrates beschrieben, mit dem auf das Substrat eine dünne Schicht eines Überzugs aufgetragen wird. Das Substrat kann insbesondere aus Glas oder einem analogen Werkstoff bestehen. Der Überzug wird durch Aufbringung von Mikrowellenenergie warm behandelt, wobei die besondere Eigenschaft darin liegt, daß diese Energie in einem ausgewählten Frequenzbereich liegt, der dazu geeignet ist, bestimmte Bestandteile des Überzugs selektiv anzuregen. Die Regelung der Mikrowelle ist derart gestaltet, daß die in den Trockenraum zugeführte Mikrowellenstrahlung in ihrer Frequenz insoweit verändert wird, daß die Temperatur der Beschichtung einen konstanten Nennwert beibehält. Dies geschieht mit einem handelsüblichen Pyrometer. Die Mikrowelle wirkt hier direkt auf die Beschichtung. Die Lacke werden teilweise speziell für die Mikrowellentrocknung modifiziert, z.B. durch Kohlestaub. Es werden ausschließlich nicht-leitende Substratwerkstoffe verwendet, wobei auch höhere Frequenzen als 2,45 Ghz Anwendung finden.FR 24 58 323 describes a method for coating a Described substrate with which a thin on the substrate Layer of a coating is applied. The substrate can consist in particular of glass or an analog material. The coating is made by applying microwave energy treated warm, the special feature of which is that this energy in a selected frequency range lies, which is suitable for certain components of the Selectively stimulate coating. The regulation of the microwave is designed in such a way that the microwave radiation fed into the drying room so far changed in frequency is that the temperature of the coating is constant Maintains nominal value. This is done with a commercially available Pyrometer. The microwave directly affects the coating here. Some of the varnishes are specially made for microwave drying modified, e.g. through coal dust. It will uses only non-conductive substrate materials, frequencies higher than 2.45 Ghz are also used.

Aus der DE 41 21 203 A1 sind ein Verfahren und eine Vorrichtung zum Trocknen von wasserlöslichem Dispersionslack auf Papier- oder Kartonbahnen oder -bögen mit Hilfe von Mikrowellen bekannt. Es werden vorzugsweise im Handel erhältliche und zugelassene Oszillatoren eingesetzt, die in mehrfacher Anordnung die Mikrowellenenergie in Hohlleiter einkoppeln. Die Bahnen oder Bögen werden im Durchlauf getrocknet, und nach dem Trocknen verbleibt eine zu vernachlässigende Restfeuchte bei sparsamstem Energieeinsatz.DE 41 21 203 A1 describes a method and a device for drying water-soluble dispersion varnish Sheets of paper or cardboard or sheets using microwaves known. They are preferably commercially available and approved oscillators used in multiple Coupling the microwave energy into the waveguide. The webs or sheets are dried continuously, and after drying, a negligible residual moisture remains with the most economical use of energy.

Baugruppen in den Trocknungsraum eingeleitet wird, daß die eingeleitete Luft mit einem Zusatzstoff mit Dipolcharakter derart angereichert wird, daß das Luftgemisch einen relativen Anteil an Zusatzstoff innerhalb eines vorgegebenen steuerbaren Bereiches von 20% bis 90% aufweist, und daß der Anteil an Zusatzstoff im Trocknungsraum eingehalten wird.The object is achieved in that as Heat source in the drying room at least one microwave module for the generation of by means of waveguides with defined Exit openings in the drying room introduced microwaves that air is used to flow around the individual parts or assemblies introduced into the drying room is that the air introduced with an additive Dipole character is enriched in such a way that the air mixture a relative proportion of additive within a given controllable range from 20% to 90%, and that the proportion of additive in the drying room is observed becomes.

Mit dem erfindungsgemäßen Verfahren wird vorteilhafterweise eine schnelle Trocknung von Bauteilen beliebiger Geometrie bei verhältnismäßig geringen Temperaturen sowie bei einer gleichmäßigen Erwärmung der Lackoberflächen erzielt, was besonders für von im Luftfahrzeugbau verwendete Aluminiumbauteile oder Bauteilen aus Faserverbundwerkstoffen von Vorteil ist. Das erfindungsgemäße Verfahren macht sich in vorteilhafterweise den Umstand zunutze, daß zum Ablauf einer wirkungsvolleren chemischen Vernetzung ein Teil des Zusatzstoffes für die die Einzelteile oder montierten Baugruppen umgebende Luft als Reaktionspartner dient. Das aus Luft und einem bei gemischten Zusatzstoff hergestellte Luftgemisch umströmt die im Trocknungsraum befindlichen Bauteile oder Baugruppen, wobei die Moleküle des Luftgemisches von den Mikrowellen in Schwingungen versetzt werden. Die auf diese Weise im Luftgemisch entstehende Wärmeenergie wird auf die zu trocknende Lackoberfläche übertragen und begünstigt die chemische Vernetzung. Hierbei können beispielsweise neun Mikrowellenmodule mit jeweils vier Magnetrons mit einer Hochfrequenzleistung von z. B. jeweils 1,2 KW verwendet werden.

Here, for example, nine microwave modules with four magnetrons each with a high-frequency power from Z. B. 1.2 KW each can be used.
