Definitions
- the invention relates to an operating element, in particular an operating element for a motor vehicle, made of a transilluminable material which is provided with at least one opaque coating and with a transparent lacquer layer on the coating.
- a preferred field of application of the invention is in the field of motor vehicles and there with controls, which are backlit for the most part. It is also conceivable to use the invention on controls of consumer electronics, in the range of kitchen appliances or washing machines, the so-called white goods, just where controls are used, which are backlit and have a metallic appearance of their appearance should.
- preferably translucent plastics are used here, which offer the possibility to illuminate the control element or the button from a rear side by means of a light source and to backlight a introduced into the coating of the control element or the button symbolism.
- a preferred material used for this purpose is polycarbonate (PC) or polymethylmethacrylate (PMMA), these plastics offer favorable properties in terms of processing and through- or backlighting.
- the components are molded from a plastic and provided by various methods with a metallic coating.
- Metallic coatings which have a high-gloss chrome finish or the appearance of aluminum (AL) or ruthenium (RU) or a comparable glossy surface are, according to the current state of the art, usually applied by a galvanization or PVD (Physical Vapor Deposition) method.
- metallization usually takes place after the process steps: palladium nucleation, reduction, chemical metallization, for example by means of nickel or Copper, and galvanic reinforcement, for example with chrome.
- the metallization takes place by means of a physical deposition from the gas phase, for example by means of vapor deposition.
- PVD physical vapor deposition
- this method offers the possibility of direct metallization of the surface of the material or of a component, wherein the metallic coating consists of one or more superimposed identical or different metal layers.
- materials or components with lower surface energies can be coated.
- the surface energies of the materials or components are activated by means of a plasma, whereby a very good adhesion to polymers is produced.
- a gas or a gas mixture is subjected to an electrical gas discharge in a vacuum.
- a metallized plastic component and a method for producing a metallized plastic component having a metallic coating and a coating applied to the metallic coating lacquer layer, which may be present in undyed form is described.
- a control element which is provided with a metallic coating, which is applied for example by means of a PVD process.
- a symbolism is introduced into the operating element by means of a laser.
- a metal layer is then deposited on this first metallic coating, for example by means of a galvanic process, so that a metallic coating consisting of two layers is produced, in which the area exposed in advance is not provided with the metallic coating.
- the disadvantage here is that the symbolism must represent a coherent area, since the liable mediating first coating for electroplating must be placed under tension. There are thus no symbols representable, which have metallic areas in their interior.
- the symbolism in one step should be recoverable.
- the object of the invention is achieved in that the transparent lacquer layer is provided with nanoparticles and that the coating and the lacquer layer is partially removed by means of a laser.
- the inventive composition of the transparent lacquer layer, which can also be labeled as a clear lacquer layer, and the integrated nanoparticles, according to the invention now provides the possibility that the clear lacquer can be removed by means of the energy of the laser irradiation. By selecting the particles in the nanometer range, the clearcoat layer remains transparent and can be activated simultaneously by means of the laser irradiation. It is thus possible to produce the control element or the control knob with an opaque coating and a clearcoat layer applied above and then incorporate a symbolism in the operating element or the button in one operation.
- the clearcoat layer remains transparent, so that the seemingly metallic appearance of the control element is retained.
- the diameters of the nanoparticles are in the range between 10 nm and 10 ⁇ m and are thus not visible in the clearcoat layer.
- Figure 1 shows the section through an operating element for a motor vehicle, for example, represents a button for a climate control device.
- FIG. 1 shows the section through an operating element 1 designed according to the invention, which is designed in the form of a key 1.
- the key 1 is hollow in its interior, and has different thicknesses.
- an opaque coating 3 is applied, on which in turn a clearcoat film 4 has been applied.
- a symbolism 5 was introduced by means of a laser.
- a light source 7 is arranged, which emits light L at least in the direction of the upper side 8 of the key 1.
- the key body 2 is limited in terms of its chemical and physical properties only in so far that it consists at least partially of a translucent material selected from the group: glass, ceramic and polymers.
- the material is made of a polymer.
- Preferred polymers are plastics, such as polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS, (PC + ABS) black, polyamide (PA) or polymethyl methacrylate (PMMA).
- Transparent ceramics such as, for example, a sapphire, can also be used Depending on the required light intensity of the symbol 5, it is conceivable in this case to form the material of the key base body 2 in different thicknesses 9, 10. As shown in FIG. 1, the thicknesses in the regions 9 and 10 are different, in order thus to provide sufficient Luminance in the area of the symbol 5 to provide.
- an opaque coating 3 made of one or more different materials.
- the coating 3 in this case had a thickness of up to 5 microns and consists of transition metals, precious metals, alloys or oxide, carbide, nitridic metal layers, which are applied in one or more layers.
- the thickness of the coating 3 is dependent on the material used and must be chosen in each case such that it can be removed by means of a laser activation.
- the coating 3 can also be produced from a dyed lacquer.
- a primer coating as a coating 3 on the key body 2.
- the coating 3 is in any case impermeable to light, and has the advantageous property that the key base body is provided with a metallic or optically enhancing coating 3.
- the transparent clearcoat layer 4 is applied.
- the application of the clearcoat layer 4 takes place in the usual manner by means of spraying.
- nanoparticles are introduced, which can be activated by means of the energy of the laser beam, so that the clearcoat layer 4 can be removed by means of the laser.
- the nanoparticles consist of metal oxides such as zinc oxide, indium tin oxide (ITO) and are transparent.
- the nanoparticles have a diameter of between 10 nm and 10 ⁇ m.
- the nanoparticles are used in a volume concentration of 0.01% up to 10%.
- the nanoparticles 11 are uniformly distributed in the clearcoat film 4 and shown as dots 11 in the clearcoat film 4 of FIG.
- a symbol 5 is introduced after the application of the coating 3 and the clearcoat layer 4 by means of a laser.
- the clearcoat layer 4 can be activated by means of the laser and because the coating 3 has a thickness which can be removed by means of the energy of the laser. It is thus possible according to the invention to introduce into the control element 1 any symbolism 5 after coating and spraying the button in the key 1 and in a single operation or process step. It is thus conceivable according to the invention to produce an operating element 1 which has a metallic appearance and in which a back-lightable symbolism is incorporated.
- Such controls 1 are for example in the motor vehicle as controls, in consumer electronics, in kitchen appliances or in the so-called white goods, such as a washing machine stainless steel look, used.
- the clearcoat film 4 has a thickness of up to 100 ⁇ m.
- the symbolism is thus backlashable with a suitable material, that is to say substrate, if, for example, polycarbonate is used as the translucent material.
