Tonerteilchen zerkleinert, beispielsweise granuliert wird.Shredded toner particles, for example granulated.
Aus der EP 0 647 885 A1 ist ein Toner bekannt, der zum Bedrucken von Keramik- und Glaserzeugnissen verwendet wird. Die Tonerteilchen des Toners weisen einen Pigmentkern, bestehend aus keramischen Pigmenten, auf. Der Pigmentkern ist von einer Bindemittelharzhülle umgeben. An die Bindemittelharzhülle sind Ladungs- steuerungsmittel angekoppelt. Der Toner wird unter Zuhilfenahme eines elektrostatischen Kopierverfahrens auf ein mit Gummi-Arabikum beschichtetes Papier aufgebracht. Zur Fixierung wird auf das beschichtete Papier ein Klarlack aufgetragen. Anschließend kann das Papier auf das zu beschichtende Keramikoder Glaserzeugnis aufgelegt und befeuchtet werden. Das Papier läßt sich dann abziehen, wobei die Gummi-Arabikumschicht und die darauf aufgebrachte farbige Beschichtung auf dem Keramik- oder Glaserzeugnis anhaftet. Dies wird anschließend gebrannt, wodurch die Farbpigmente mit der Oberfläche des Erzeugnisses verschmelzen. Ein solcher Toner läßt sich nur für Keramik- und Glaserzeugnisse einsetzen.A toner is known from EP 0 647 885 A1, which is used for printing on ceramic and glass products.

Charge control agents are coupled to the binder resin shell. The toner is applied to paper coated with gum arabic using an electrostatic copying process. A clear varnish is applied to the coated paper for fixation applied. The paper can then be placed on the ceramic or glass product to be coated and moistened. The paper can then be peeled off, the gum arabic layer and the colored coating applied to it adhering to the ceramic or glass product. This is then baked, causing the color pigments to fuse with the surface of the product. Such a toner can only be used for ceramic and glass products.
Es sind auch Toner bekannt, die als Basiswerkstoff einen Thermoplasten aufweisen. Dieser ist mit Farbpigmenten und Ladungssteuerungsmitteln versetzt. Der Toner wird im elektrostatischen Druckverfahren auf ein zu beschichtendes Papier aufgebracht. Anschließend wird der beschichtete Träger bei einer Temperatur von 90° C - 1 70° C fixiert.Toners are also known which have a thermoplastic as the base material. This is mixed with color pigments and charge control agents. The toner is applied to a paper to be coated using the electrostatic printing process. The coated support is then fixed at a temperature of 90 ° C - 1 70 ° C.
Diese Toner eignen sich nicht für die Beschichtung von Werkstoffen, bei denen hohe Anforderungen an die Oberflächenbeständigkeit, insbesondere Kratzfestigkeit gestellt werden.These toners are not suitable for the coating of materials where high demands are placed on surface resistance, especially scratch resistance.
Es ist Aufgabe der Erfindung, ein Beschichtungsmaterial der eingangs erwähnten Art zu schaffen, mit dem sich Oberflächenbeschichtungen mit hoher Oberflächenqualität auf nahezu beliebigen Werkstoffen erzeugen lassen.It is an object of the invention to provide a coating material of the type mentioned at the outset with which surface coatings with a high surface quality can be produced on almost any material.
Es ist weiterhin Aufgabe der Erfindung, ein Verfahren zur Herstellung ein solchen Beschichtungsmaterial bereitzustellen.It is a further object of the invention to provide a method for producing such a coating material.
Diese Aufgaben werden dadurch gelöst, dass zumindest ein Teil der Materialteilchen die Duromer-Bestandteile Harz und Härter aufweist. Erfindungsgemäß wird also ein Beschichtungsmaterial bereitgestellt, das auf dem zu beschichtenden Werkstück einen duromerischen Überzug bildet. Hierbei werden die Eigenschaften des Duromers ausgenützt um gute Oberflächenqualitäten, insbesondere kratz- und wärmebeständige Oberflächen zu erzeugen.These objects are achieved in that at least some of the material particles have the thermoset components resin and hardener. According to the invention, a coating material is thus provided which forms a thermoset coating on the workpiece to be coated. The properties of the thermoset are used to produce good surface qualities, especially scratch and heat resistant surfaces.
Der Überzug kann beispielsweise ein Farbüberzug sein, mit dem die Oberfläche eines Werkstückes farblich gestaltet werden kann. Denkbar ist es auch, dass der Überzug dazu verwendet werden soll, die Oberflächeneigenschaften eines Werkstückes zu beeinflussen. Dabei kann die Verschleiß- oder Korrisionseigenschaft oder auch der Reibkoeffizient beeinflusst werden. Über elektrostatische Verfahren lässt sich das Beschichtungsmaterial gezielt an solchen Werkstückstellen anbringen, an denen die Oberfläche beeinflusst werden soll.The coating can, for example, be a color coating with which the surface of a workpiece can be colored. It is also conceivable that the coating should be used to influence the surface properties of a workpiece. The wear or corrosion properties or the coefficient of friction can be influenced. Using electrostatic processes, the coating material can be applied in a targeted manner to those workpiece locations at which the surface is to be influenced.
Um Oberflächen farblich gestalten zu können, werden dem Beschichtungsmaterial Farbmittel zugesetzt. Als Farbmittel können Pigmente oder Farbstoffe verwendet werden. Bei der Verwendung von Pigmenten eignen sich insbesondere Sulfide. Hierbei seien insbesondere auch die Zinksulfidpigmente erwähnt, die sich durch einen hohen Weißgrad und hohe Lichtechtheit auszeichnen. Aufgrund ihrer niedrigen Härte erzeugen sie nahezu keinen Werkzeugverschleiß und keine Beeinträchtigung der mechanischen Eigenschaften des Kunststoffes. Der ZnS- Anteil dieser Zinksulfid-Pigmente wirkt als Trockenschmierstoff. Denkbar ist auch die Verwendung von anorganischen Buntpigmenten. Diese zeichnen sich vor allem durch eine hohe Deckfähigkeit aus. Erwähnt seien in diesem Zusammenhang auchColorants are added to the coating material in order to be able to design surfaces in color. Pigments or dyes can be used as colorants. When using pigments, sulfides are particularly suitable. Zinc sulfide pigments, which are characterized by a high degree of whiteness and high light fastness, should also be mentioned here. Due to their low hardness, they produce almost no tool wear and no impairment of the mechanical properties of the plastic. The ZnS content of these zinc sulfide pigments acts as a dry lubricant. The use of inorganic colored pigments is also conceivable. These are characterized above all by their high opacity. In this context it should also be mentioned

Bei den Metallkomplex-Pigmenten zeichnen sich die Naphthol-AS-Pigmente durch Farbstärke, Lichtechtheit und Chemikalienbeständigkeit aus. Weiterhin eignen sich ebenfalls die Diazokondensations-Pigmente bei den Metallkomplex-Pigmenten, wenn der Werkstoff in rauhen Umgebungsbedingungen eingesetzt werden soll. In diesem Zusammenhang zeichnen sich die Diazokondensations-Pigmente vor allem durch Lösemittel- und Migrationsechtheit, Temperaturbeständigkeit und Farbstärke gut aus. Ebenso sind diese Pigmente licht- und wetterecht.Chromium oxide pigments that are particularly light, weather and temperature resistant. In the metal complex pigments, the Naphthol-AS pigments are characterized by color strength, light fastness and chemical resistance. Furthermore, the diazo condensation pigments are also suitable for the metal complex pigments, if the material is to be used in harsh environmental conditions. In this context, the diazo condensation pigments are particularly characterized by their fastness to solvents and migration, temperature resistance and color strength. These pigments are also lightfast and weatherproof.
