Coating Material and Method for Producing a Coating Material The invention relates to a coating material for an electrostatic printing method with material particles.
Morcover, the invention also relates to a method for producing a coating material, wherein a basic plastic material is mixed in a mixing device with the application of heat to foam a raw toner material, and wherein the raw toner material is comminuted, for examplc granulated, downstream of the mixing device to form toner particles.
A toner which is used for printing on ceramic and glass products is known from EP
0 647 885 Al . The toner particles of the toner have a pigment core consisting of ceramic pigments.
The pigment core is surrounded by a binder resin shell. Charge control agents ate connected to the binder resin shell. With the aid of an electrostatic copying process the toner is placed on a paper coated with gum arabic. A clear lacquer is applied to the coated paper for fixing. Thereafter, the paper can be placed on the ceramic or glass product to be coated and can be wetted. The paper can then be pulled off, while the gum arabic layer and the colvrcd coating applied to it adhere to the ceramic or glass product. The latter is subsequently fired, so that the color pigments melt together with the surface of the product. Such a toner can only be employed in connection with ceramic and glass products.
~~~ . . . . . b ....___ Toners are also lrnown, which have a thermoplastic material as the basic material.
The toner is mixed with color pigment and charge control agents, The toner is applied by means of an electrostatic printing process to a paper to be coated. Thereafter the coated support is fixed at a temperature between 90 ° C and 170 ° C.
These toners are not suitable for coating materials in connection with which high demands are made on the surface resistance, in particular scratching resistance.
It is the object of the invention to create a coating material of the type mentioned at the outset, by means of which surface coatings of a high surface quality can be produced on almost any arbitrary materials, It is furthczznore an object of the invention to make available a method for producing such a coating material.
These objects are attained in that at least a portion of the material particles has the duromer components of resin and hardener.
Thus, a coating material is made available by the invention, which forms a duromer coating on the workpiece to be coated. In this case the properties of the duromer are used for creating good surface qualities, in particular scratch- and heat- resistant surfaces, The coating can be a colored coating, for example, by means of which the surface of a workpiece can be designed in colors, It is also conceivable that the coating is used for affecting the surface properties of a workpiece. In this case the wear or corrosion properties, but also the _.
"' CA 02377691 2001-12-28 WO 01 /01202 PCTlEP00/05481 coefficient of friction, can be affected. By means of electrostatic processes it is possible to apply the coating material specifically at places of the workpieces where the surface is intended to be affected.
Coloring agents are added to the coating material so that it is possible to design the surfaces in colors. Pigments or dyestuffs can be used as coloring agents.
Sulfides are particularly suitable when using pigments. Zinc sulfide pigments in particular should also be mentioned, which are distinguished by a high degree of whiteness and great fade resistance.
Because of their low hardness they generate almost no tool wear and no impairment of the mechanical properties of the plastic material. The ZnS portion of these zinc sulfide pigments acts as a dry lubricant. The use of inorganic colored pigments is also conceivable. These are particularly distinguished by a high degree of covering capacity. Chromium oxide pigments should also be mentioned in this connection, which arc particularly light-, weather- and temperature-resistant. Among the metallizcd pigments, the naphthol-AS pigments are distinguished by color intensity, fade resistance and chemical resistance.
The diazo- condensation pigments among the metahized pigments are furthermore also suitable, if the material is intended to be used undo rough surrounding wnditions. In this connection the diazo-condensation pigments are greatly distinguished mainly by solvent- and migration-resistance, temperature resistance and color intensity. These pigments are also light- and weather-resistant.
So that the material particles can be applied to the workpiece to be coated by means of the electrostatic printing process, it is provided in accordance with an embodiment variation of the invention that the material particles are provided with charge-control particles, for example zinc atoms.
