Definitions
- the invention relates to a plastic toner and a method for producing a plastic toner, in particular for electrophotography.
- Powders and methods for powder coating are known. Powder is used as the material, depending on the field of application and the associated requirements, in particular the surface properties, epoxies, polyesters, polyurethanes, acrylates and combinations of these materials. Such. Materials usually have a grain size between 3 and 100 ⁇ m. These materials are available in large quantities and are also inexpensive.
- Powder coating is a mature technology for industrial surface coating.
- the paint powder used here is a plastic powder with built-in hardener based on thermosets, which is solvent-free and environmentally friendly from an ecological point of view.
- the plastic powder is applied electrostatically or tribo-technically to a grounded base material.
- the powder particles stick due to their charging on the base material.
- Subsequent exposure to heat causes the plastic to harden and, viewed from the order side, forms a decorative surface appearance.
- plastic toners in particular for electrophotography, which are inexpensive and whose properties can be adapted to a wide variety of surface requirements and can be produced in a simple manner.
- powder for powder coating is used as the basic material for the toner, which has a particle size distribution of 1 to 20 ⁇ m, in particular 5 to 15 ⁇ m, and is provided on the surface by means of additional charge control agents and additives is characterized, while the process for producing the toner is characterized in that ready-convectioned powders are used as the base materials for the powder coating, which are used in a mixing process with charge control agents (CCA) to improve the surface charge and, if appropriate, in a further mixing process with additives to improve the flow behavior, the adhesiveness and the tendency to agglomeration.
- CCA charge control agents
- the basic materials are taken from the plastic coating, which are offered in a wide variety of properties on the market at a reasonable price and in all imaginable colors. This basic materials correspond to what the material properties already largely affect the plastic toners used in electrophotography.
- charge control agents and additives - By loading the powders used as base materials with charge control agents and additives - in one or two mixing processes - it is possible to achieve the required surface charge and the properties that improve the flow behavior, the cleaning behavior and the tendency towards agglomeration, which are the basic materials of the Powder coating does not yet meet the requirements of electrophotography.
- the basic materials of the powder coating does not yet meet the requirements of electrophotography.
- Powder coating has been modified so that it can be used as a plastic toner for electrophotography. After that, an inexpensive plastic toner is available for electrophotography with the possibility of largely adapting to the requirements in quantities. If the base material is not in the desired grain size range, an additional grinding and classifying process may have to be carried out.
- the selection of starting materials can be made so that epoxies, polyesters, polyurethane, melamine, acrylates and other powder loading materials as well as combinations of these are used as basic materials
- the adaptation for use as a plastic toner can take place in such a way that the charge control substances and the additives are selected depending on the base material and that the charge control substances and additives are selected according to the surface chemistry of the base materials, whether hydrophilic or hydrophobic plastics.
- Additives such as aerosils and / or silanes can be used.
- the grain size can also be largely maintained, it being provided according to one embodiment that aerosils and / or silanes are used as additives.
- the graphic in FIG. 1 shows, for example, depending on the mixing time, the course of the specific charge (q / m) for differently processed powder coating base materials.
- Curve 1 describes the time course for untreated basic material.
- Curve 2 shows the influence when, for example, 0.5% charge control agents (CCAs) are added.
- CCAs charge control agents
- Curve 3 describes the course when 0.5% aerosils are added.
- Curve 4 shows the influence of 0.5% charge control agents and 0.5% aerosils.
- the mixing process can be carried out in a tumble mixer or paddle mixer.
- a grinding and classifying operation which may be upstream, to adapt the core size distribution takes place, for example, in a counter jet mill.
- the extrusion process as is normal, can be omitted. This is particularly advantageous if different colors are to be processed in quick succession, since the time-consuming cleaning of the extrusion device can be omitted.
