Description

Patent- und GebrauchsmusterhilfsanmeldungPatent and utility model auxiliary application "Druckvalze in Verbundkörperbauweise""Pressure valves in composite construction"

Die Erfindung betrifft eine Druckwalze gemäß dem Oberbegriff des Hauptanspruchs und umfaßt ein Verfahren zur Herstellung eines Verbundkörpers hierfür.The invention relates to a pressure roller according to the preamble of the main claim and comprises a method for producing a composite body therefor.

Bisher war es üblich, Druckwalzen, wie sie insbesondere in der Tiefdrucktechnik verwendet werden, aber auch bei Kopiergeräten und dergleichen, dadurch herzustellen, daß man Stahlzylinder relativ großer Länge mechanisch bearbeitet, poliert und genauestens auswuchtet, da sie im Betrieb mit hoher Geschwindigkeit umlaufen müssen. Es handelt sich bei derartigen Walzen im wesentlichen um sehr dickwandige Zylinder, da die mechanischen Anforderungen bei den hohen Druckgeschwindigkeiten erheblich sind.So far, it has been customary to produce printing rollers, such as are used in particular in gravure printing technology, but also in copiers and the like, by mechanically machining, polishing and balancing steel cylinders of relatively long length, since they have to rotate at high speed during operation. Such rollers are essentially very thick-walled cylinders, since the mechanical requirements at the high printing speeds are considerable.

Auf den Stahlzylinder als Träger wird eine Kupferschicht von etwa 1 mm Dicke auf dessen Umfang elektrolytisch niedergeschlagen. Um die Schicht glatt zu halten und gleichzeitig zu verdichten, wird sie während eines etwa 15 Stunden dauernden Schichtwachstums durch eine mitlaufende Achatrolle verdichtet. Auf diese Kupferschicht kommt dann eine Silberschicht als Trennschicht. Über der Silberschicht wird sodann ebenfalls elektrolytisch eine weitere Kupferschicht abgeschieden. Nach den üblichen photolythographischen Arbeitsgängen erfolgt die Ätzung der Tiefdruckgruben mit einem chemischen Ätzmittel. Die Tiefe der Tiefdruckgrubcn beträgt etwa 20 bis 30 µm.A copper layer approximately 1 mm thick is electrolytically deposited on the circumference of the steel cylinder as a carrier. In order to keep the layer smooth and to compact it at the same time, it is compacted by a moving agate roller during about 15 hours of layer growth. A silver layer is then placed on this copper layer as a separating layer. A further copper layer is then also electrolytically deposited over the silver layer. After the usual photolythographic operations, the gravure pits are etched with a chemical etchant. The depth of the rotogravure pits is approximately 20 to 30 µm.

lm Betrieb wird vor der Druckwalze, nachdem die erforderliche Auflage einer Zeitschrift oder dergleichen gedruckt ist, der äußere Mantel von der Druckwalze mechanisch, insbesondere unter Zuhilfenahme von Zangen, abgenommen, eine neue Silberschicht aufgebracht und erneut eine Kupferschicht darauf abgeschieden, womit der Tiefdruckzylinder für die Fotobelichtung und die Ätzung einer weiteren Klischeevorlage erneut bereitsteht.In operation, in front of the printing roller, after the required edition of a magazine or the like has been printed, the outer jacket is removed mechanically from the printing roller, in particular with the aid of pliers, a new layer of silver is applied and a copper layer is deposited thereon again, with which the gravure cylinder for the Photo exposure and the etching of another cliché template is available again.

Der wesentliche Nachteil ist bei diesem Verfahren, welches über viele Jahrzehnte hinweg praktiziert wurde, vor allem, daß es nicht einfach ist, den äußeren Mantel abzuziehen und daß dabei Beschädigungen des Walzenträgers häufig auftreten. Dies wiederum erfordert Nacharbeiten der Druckwalze im Herstellerwerk, Ausbau und Wiedereinbau am Aufstellort der Druckmaschine, Transportkosten und weitere Kosten.The main disadvantage of this method, which has been practiced for many decades, is above all that it is not easy to remove the outer jacket and that damage to the roller carrier often occurs. This in turn requires reworking of the printing roller in the manufacturing plant, removal and reinstallation at the location of the printing press, transport costs and other costs.

Aufgabe der Erfindung ist die Schaffung einer Druckwalze in Verbundkörperbauweise derart, daß der äußere Mantel leicht und ohne Schaden für die Walze von jedermann entfernbar ist.The object of the invention is to provide a pressure roller with a composite structure in such a way that the outer jacket can be removed easily and without damage to the roller by anyone.

Gelöst wird diese Aufgabe durch den besonderen Schichtaufbau des Verbundkörpers, der gemäß einem weiteren Merkmal der Erfindung auf einfachste Weise hergestellt werden kann.This object is achieved by the special layer structure of the composite body, which can be produced in the simplest way according to a further feature of the invention.

Die wesentlichsten Vorteile der Erfindung sind:

  • Eine wesentliche Zeitersparnis für den Schichtaufbau, was der Tiefdrucktechnik neue Anwendungsgebiete eröffnet.
The main advantages of the invention are:
  • This saves a significant amount of time for layer build-up, which opens up new areas of application for rotogravure technology.

Die Außenschicht muß nicht mehr mechanisch entfernt werden, es entfällt die Gefahr von Beschädigungen des Walzenträgers.The outer layer no longer has to be removed mechanically, there is no risk of damage to the roller carrier.

Hohe Materialkosteneinsparung, insbesondere an teueren Edelmetallen.High material cost savings, especially on expensive precious metals.

Die Erfindung wird nachstehend anhand von Ausführungsbeispielen erläutert, ohne hierauf beschränkt zu sein. In einer Ausführung der Erfindung wurde eine Druckwalze in Verbundkörperbauweise hergestellt mit einem üblichen Stahlzylinder als Träger und darauf ohne Zwischenschicht wie Silber, eine Schicht abgeschieden aus TiO1 94 - 1,96 mit 3 % Platin in Form feiner Teilchen gleichmäßig vermischt und angelagert an der Titanoxidtrennung und danach im Plasmaspritzverfahren aufgebracht. Das Edelmetall war gleichmäßig verteilt an de.n Körnern des Titanoxids in der gesamten Schicht vorhanden. Die Schicht ist dicht und von glatter hoher Flächenbeschaffenheit mit einer Rautiefe kleiner als 25 gm, etwa von 5 - 15 µm und die erzeugte Schichtdicke lag im Bereich von etwa 100 µm, insbesondere nach mechanischer Bearbeitung wie Schleifen und Polieren. Die Walze wurde mit gutem Erfolg betrieben und es hat sich herausgestellt, daß man Kupfer auf der Walze sehr schnell und einfach kathodisch niederschlagen und durch elektrisches Umpolen danach anodisch wieder ablösen kann.The invention is explained below on the basis of exemplary embodiments, without being restricted thereto. In one embodiment of the invention, a pressure roller was produced in a composite structure using a conventional steel cylinder as a support and thereon without an intermediate layer such as silver, a layer deposited from TiO 1 94-1.96 with 3% platinum in the form of fine particles, mixed uniformly and attached to the titanium oxide separation and then applied by plasma spraying. The precious metal was evenly distributed on the grains of the titanium oxide throughout the layer. The layer is dense and has a smooth, high surface quality with a roughness depth of less than 25 gm, approximately from 5 to 15 μm, and the layer thickness produced was in the range of approximately 100 μm, especially after mechanical processing such as grinding and polishing. The roller was operated with good success and it has been found that copper can be deposited on the roller very quickly and easily cathodically and then anodically detached again by electrical polarity reversal.

Man hat festgestellt, daß eine Druckwalze in dieser Verbundkörpcrbauweise mehr als 125 Zyklen'für das Aufbringen und Entfernen von Kupferschichten durchstehen kann.It has been found that a pressure roller in this composite construction can withstand more than 125 cycles for the application and removal of copper layers.

Beispiel einer Herstellung:

  • Das Matrixmaterial wie Titanoxid wird z. B. in einem Wirbelbett durch Spritzen hergestellt, wobei das Salz in einem Nebel im Gegenstrom auf das Wirbelbett gespritzt wird. Dabei werden die Teilchen des Matrixmaterials sehr homogen mit aktivem Material bedeckt, d. h., daß die Teilchen des aktiven Materials regelmäßig verteilt auf der Oberfläche der Matrixkörner liegen. Bei dem Verfahren wird also das Matrixmaterial wie Titanoxid in Form von Pulver (Körnung) verwendet, wobei das aktive Material aus Edelmetall wie Platin in Form eines Salzes in einem leichtdestilierbaren Lösungsmittel aufgelöst wird.
Production example:
  • The matrix material such as titanium oxide is e.g. B. in a fluidized bed by spraying, the salt being sprayed in a mist in countercurrent onto the fluidized bed. The particles of the matrix material are covered very homogeneously with active material, ie the particles of the active material are regularly distributed on the surface of the matrix grains. The method therefore uses the matrix material such as titanium oxide in the form of powder (grain size), the active material consisting of noble metal such as platinum being dissolved in the form of a salt in an easily distillable solvent.

Beispiel':

  • 2,5 g Hexachloroplatinat werden in 120 ml Metanol gelöst. In einer Eindampfschale werden 100 g nichtstöchiometrisches Titanoxid mit Korngröße -100 +37 mym abgewogen. Dann wird zu diesem Titanoxid die Lösung zugegeben und anschließend wird unter ständigem Rühren über einem Wasserbad das Metanol abgedampft. Wenn das Pulver fast trocken ist, wird in einem Trockenschrank weitergetrocknet bei einer Temperatur von 105 °C. Nach zwei Stunden wird das Pulver dann aus dem Ofen genommen und mit einem Mörser leicht zerkleinert, so daß das entstandene Konglomerat wieder auf ursprüngliche Körngröße gebracht wird. Jetzt wird das Pulver in einem Tiegel im Muffelofen auf 550 °C 4 Stunden lang erhitzt. Wenn das Pulver aus dem Ofen kommt und abgekühlt ist, wird es mit einem Mörser leicht gemahlen bis zur ursprünglichen Korngröße. Dann wird das Pulver gesiebt und mit Korngröße -100 +37 mym als Spritzpulver zur Beschichtung benutzt.
Example':
  • 2.5 g of hexachloroplatinate are dissolved in 120 ml of methanol. 100 g of non-stoichiometric titanium oxide with a grain size of -100 +37 μm are weighed out in an evaporation dish. The solution is then added to this titanium oxide and then the methanol is evaporated off with constant stirring over a water bath. When the powder is almost dry, continue drying in a drying cabinet at a temperature of 105 ° C. After two hours, the powder is then removed from the oven and lightly crushed using a mortar, so that the conglomerate formed is brought back to the original grain size. Now the powder is heated in a crucible in a muffle furnace to 550 ° C for 4 hours. When the powder comes out of the oven and has cooled, it is lightly ground with a mortar to the original grain size. Then the powder is sieved and used with a grain size of -100 +37 mym as a spray powder for coating.

Ein Stahlzylinder mit einem Durchmesser von etwa 200 bis 400 mm und einer Länge bis etwa 2000 mm wird nach üblicher Vorbehondlung, wie z. B. Sandstrahlen mittels eines Plasmabrenners, Typ F 4 (Firma Plasmatechnik), mit dem aktivierten Pulver, d. h. Titanoxid mit daran angelagertem Platin beschichtet. An Stelle von Platin wurde auch Iridium oder Ruthenium auch als Oxid mit dem Ventilmetalloxid gemischt und gleichmäßig verteilt angelagert. Auch die anderen Edelmetalle der Platingruppe und Gold und Silber sind geeignet. Sie erfüllen ebenfalls die Bedigung gut elektrisch leitend und elektrochemisch aktiv zu sein, was auch für die erwähnten Oxide der Platinmetallgruppe gilt. Die elektrische Leitfähigkeit steigt in der Regel mit zunehmendem Prozentgehalt an Edelmetall in dem vermischten bzw. verbundenen Pulver: Matrix plus aktive Teilchen. Andereseits wird man wegen des hohen Preises der Edelmetalle versucht sein, den Anteil zu begrenzen. Das Ventilmetalloxid ist üblicher Art, z. B. wie das käuflich erhältliche Titanoxid unter dem Handelsnamen "Amperit" (Firma Starck).A steel cylinder with a diameter of about 200 to 400 mm and a length of up to about 2000 mm is after conventional pretreatment, such as. B. sandblasting using a plasma torch, type F 4 (company Plasmatechnik), with the activated powder, d. h . Titanium oxide coated with platinum attached to it. Instead of platinum, iridium or ruthenium was also mixed as oxide with the valve metal oxide and deposited evenly distributed. The other platinum group precious metals and gold and silver are also suitable. They also fulfill the requirement of being electrically conductive and electrochemically active, which also applies to the oxides of the platinum metal group mentioned. The electrical conductivity generally increases with an increasing percentage of precious metal in the mixed or combined powder: matrix plus active particles. On the other hand, one will be tempted to limit the share due to the high price of the precious metals. The valve metal oxide is of a conventional type, e.g. B. as the commercially available titanium oxide under the trade name "Amperit" (Starck).

Die Bedingungen des Plasmaspritzverfahrens waren Stromstärke 400 A, Spannung 70 Volt, Plasmagas Stickstoff 26 1 pro Minute, Wasserstoff 2 1 pro Minute, Spritzabstand 150 mm.The conditions of the plasma spraying process were current 400 A, voltage 70 volts, plasma gas nitrogen 26 1 per minute, hydrogen 2 1 per minute, spraying distance 150 mm.

An Stelle des Plasmaspritzverfahrens kann auch ein übliches Lichtprobenspritzverfahren angewendet werden.Instead of the plasma spraying process, a conventional light sample spraying process can also be used.

Auf der Spritzschicht wird dann eine Kupferschicht galvanisch niedergeschlagen, z. B. mit einem Elektrolyt der 0,5 N-Kupfersulfatlösung in 5 % Schwefelsäure enthält. Die Elektrolysebedingungen wurden wie folgt gewählt:

Figure imgb0001
Die gewählte Herstellung hat die in der Beschreibung erwähten Vorteile gebracht.A copper layer is then galvanically deposited on the spray layer, e.g. B. with an electrolyte of 0.5 N copper sulfate solution in 5% sulfuric acid. The electrolysis conditions were chosen as follows:
Figure imgb0001
 The chosen production has brought the advantages mentioned in the description.

Für den Erfolg maßgebend sehen es die Erfinder vor allem an, daß die elektrochemisch aktiven Teilchen vor dem Aufbringen durch eines der erwähnten thermischen Spritzverfahren mit dem im jeweiligen Elektrolyten inerten und elektrisch leitenden Matrixmaterial verbunden ist.For the success, the inventors see it above all that the electrochemically active particles are connected to the inert and electrically conductive matrix material in the respective electrolyte before application by one of the thermal spray processes mentioned.
