Definitions
- the invention relates to a coating material for an electrostatic printing process with material particles.
- the invention also relates to a method for producing a coating material, wherein a plastic base material is mixed in a mixing device under the action of temperature to form a raw toner mass, and wherein the raw toner mass follows the mixing device
- Shredded toner particles for example granulated.
- a toner is known from EP 0 647 885 A1, which is used for printing on ceramic and glass products.
- 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 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.
- 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.
- thermoset components resin and hardener are used to produce good surface qualities, especially scratch and heat resistant surfaces.
- 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.
- Colorants are added to the coating material in order to be able to design surfaces in color.
- Pigments or dyes can be used as colorants.
- 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.
- inorganic colored pigments is also conceivable. These are characterized above all by their high opacity. In this context it should also be mentioned
- Chromium oxide pigments that are particularly light, weather and temperature resistant.
- the Naphthol-AS pigments are characterized by color strength, light fastness and chemical resistance.
- the diazo condensation pigments are also suitable for the metal complex pigments, if the material is to be used in harsh environmental conditions.
- 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.
- the material particles can be applied to the workpiece to be coated in the electrostatic printing process, it is provided according to one embodiment variant of the invention that the material particles are also
- Charge control particles are provided, for example, zinc atoms.
- the charge control particles should be electrostatically charged or electrostatically chargeable.
- an acid hardener or a peroxide can be used as the resin.
- part of the material particles is designed as a filler, for example as wood flour, cellulose powder, shell flour, core flour, aluminum trihydrate, electro-corundum, cryolite, barite, blanc fixe, barium ferrite, calcium carbonate, dolomite, coal, graphite, andalusite , Feldspar, mica, kaolin, kieselguhr, massive microspheres, hollow microspheres, mullite, olivine, sillimanite, nepheline, talc, quartz sand, quartz powder, slate powder, silicon carbide and / or wollastonite.
- the fillers the density, the modulus of elasticity, the pressure and bending strength, the hardness, the dimensional stability under heat, the surface quality and - depending on the type of filler - the antistatic behavior or the fire protection effect of the fillers, the density, the modulus of elasticity, the pressure and bending strength, the hardness, the dimensional stability under heat, the surface quality and - depending on the type of
- Coating can be influenced. Furthermore, the tensile and shear strength as well as the heat resistance can be improved when using fibrous fillers.
- the resin can be, for example, a phenol, a urea or a melamine
- Formaldehyde an epoxy or an unsaturated polyester resin are used.
- the phenolic resins are characterized by their high degree of crosslinking due to their high strength, rigidity and hardness. Furthermore, they have a low one
- the melamine / formaldehyde resins can preferably be used when high Surface hardness and scratch resistance as well as high surface gloss is required. In addition, these resins can be used in the manufacture of food-safe items.
- thermoplastic as the basic component, the melting temperature of which is greater than 1 70 ° C. It has been shown that these thermoplastics in particular can be used to produce scratch-resistant surface coatings.
- thermoplastic a polystyrene-based thermoplastic or an epoxy bisphenol A
- an extruder can be used, for example, as a mixing device.
- Resin and hardener can be introduced into this extruder and heated here to a temperature which is higher than the melting temperature of resin and hardener but lower than the thermosetting crosslinking temperature.
- the color pigments and the charge control particles can be fed into the extruder so that a complete and uniform mixing of resin, hardener, color pigments and charge control particles can take place.
- the raw toner mass is removed from the mixing device and cooled. It can then be comminuted, for example granulated, in order to produce the individual material particles.
