    Layer structure for a lane marking
    The invention relates to a method for producing a layer structure for a pavement marking and a layer structure produced by this method, as well as the use of this layer structure for a pavement marking.
    Poor visibility is one of the most common causes of personal injury, with pedestrians, cyclists and road workers particularly at risk. Eye-catching colored and reflective road markings are used to increase the attention of road users in these cases. This applies in particular to road construction sites when existing traffic routing needs to be changed, but also to protection routes. Especially at night, in rain or fog, however, existing road markings are bad or not visible in the worst case. This results in an increased risk of accidents, especially in construction sites, at driveways and protection routes. Especially pedestrians are exposed to an increased risk.
    In order to increase the visibility of lane markings, lane markings are known from the prior art, which are reflective designed to reflect the headlights of the vehicles and thus to ensure greater visibility. Such reflective road markings have the advantage that they can be glued easily in the form of adhesive strips on roads and have a small depth. However, it has been shown that it is not sufficient in adverse visibility to reflect the headlight, but an active lighting is needed. z 50460 Ag / Fl Christoph Thalner
    For this purpose, it is further known from the prior art to install light-emitting diodes on the roadway, which generate punctiform markings on the road, whereby the traffic can be conducted accordingly. Although such punctiform markings are clearly visible, they are expensive and only of limited suitability for flat markings, in particular directional arrows or road symbols, since this would require a large number of light-emitting diodes.
    The technical object of the invention is therefore to provide a method for producing a layer structure for a pavement marking, whereby the disadvantages of the devices and methods of the prior art are overcome and an easy-to-apply, areal, cheap and efficient pavement marking is realized. The road marking should have a clear visibility even in bad weather, and easy to install.
    The lane marking should be both temporarily, as well as permanently attachable to a roadway.
    This object is achieved according to the invention by presenting a method for producing a layer structure for a roadway marking, in which an electrically conductive back electrode is applied to a carrier layer; - On this back electrode, a dielectric layer is applied; - At least partially a light-emitting layer is applied to the dielectric layer; - On the light-emitting layer, an electrically conductive, transparent front electrode is applied; - On the front electrode, a light-transmitting protective layer is applied; and - a light-transmitting and / or reflective marking layer is applied to the protective layer. 3 50460 Ag / Fl Christoph Thalner
    The backing layer can be made of any dimensionally stable and flexible material, e.g. Plastic or a metal. The carrier layer can be embedded in a protective layer. In this case, the electrically conductive back electrode can be applied to the protective layer.
    The protective layer may be in the form of a sandwich of a first and a second protective layer, wherein first the carrier layer is applied to a first protective layer, and then the second protective layer is applied to the carrier layer. As protective coatings can be used, which are resistant to environmental influences and protect the carrier layer before them. The application of this paste can be done by casting, knife coating, brushing, spraying, coil coating or digital printing.
    Furthermore, an electrically conductive carrier layer can be used, whereby the carrier layer itself can be used as a back electrode, resulting in a simplified layer structure. In particular, an electrically conductive sheet can be used as the carrier layer. If the backing layer is used as a back electrode, it may comprise an electrical contact.
    The dielectric layer may comprise barium titanate, alumina, or other high dielectric constant dielectric materials. In addition to the electrical insulation of the two electrodes, this layer also has the task of reflecting the generated light to the transparent front electrode. The dielectric layer may therefore be reflective in order to reflect the light generated in the light-emitting layer. The dielectric layer may also serve as a protective layer for the carrier layer. The application of this paste can be done except by pouring, knife coating, spraying or brushing in the digital printing process.
    The light-emitting layer may be an electroluminescent layer, as known from electroluminescent films. This layer may comprise zinc sulfides, whereby the layer emits light when an alternating electromagnetic field is applied. 4 50460 Ag / Fl Christoph Thalner
    The light-emitting layer may consist of pigments which emit light when excited by an electric field. For this purpose, the light-emitting layer may comprise zinc sulfides, but it is also possible to use other pigments, in particular encapsulated or unencapsulated phosphors, which are excited to emit when an electric field is applied. Since these pigments are electrically non-conductive and also the binder used has a high dielectric constant, the light-emitting layer itself also serves as a dielectric. The light-emitting layer may be applied in the form of a pattern or a specific design. In this case, the method according to the invention may comprise the steps of applying or removing one or more masks. For the back electrode, a good electrical conductor such as silver, graphite, copper, or a similar material can be used. The application of this paste can be done except by pouring, knife coating, spraying or brushing in the digital printing process.
    The front electrode and the back electrode can be provided with electrical contacts for connecting an AC voltage source. The front electrode 9 may further be designed as a translucent electrically conductive polymer layer, in particular polyvinyl acrylate, which is to be processed dispersed in a paste. The application of this paste can be done except by pouring, knife coating, spraying or brushing in the digital printing process.
    The marking layer can be designed as a marking strip, which contains the actually to be mounted on the roadway pattern. The marking layer may be designed with increased stiction properties to provide tactical feedback to the over-riding road vehicles or to the drivers of these road vehicles. The marking layer can be applied with conventional paints already used for pavement markings. In this case, this layer can be executed interrupted, so that the light generated can shine through. s 50460 Ag / Fl Christoph Thalner
    The translucent protective layer may be embodied as a transparent layer and comprise a dissolved polyuretane (PU) or a similar plastic. The translucent protective layer can be embodied as a liquid laminate and can comprise dyes, in particular colored pigments. To bring this paste can be done except by pouring, knife coating, spraying or brushing in the digital printing process.
    The invention also relates to a layer structure which is produced by a method according to the invention. Moreover, the invention relates to the use of a layer structure according to the invention for producing a road marking on a road, wherein the layer structure applied to the roadway, in particular glued.
    Furthermore, the invention relates to the use of the layer structure according to the invention for producing a pavement marking on a roadway, wherein in the roadway a groove is milled, the layer structure according to the invention introduced into the groove, in particular glued with an adhesive layer and the groove with asphalt or another Pouring filler is poured. This has the advantage that the lane marking is flush and no obstacle, e.g. represents for a snowplow. The electrical contacts of the front and back electrodes can be provided laterally in the groove.
    The groove can in particular be made slightly larger, so that the gap after inserting the layer structure can be easily closed with the filler. As a result, an additional protection of the road marking is achieved and improves the connection of the roadway with the layer structure. For the adhesive layer, a conventional adhesive, as it is currently used for the attachment of road markings in construction sites, can be used.
    It may be provided according to the invention that the road marking according to the invention is applied to existing protective paths by a smaller groove is milled into the protective path, and the layer structure is inserted into this groove. 6 50460 Ag / Fl Christoph Thalner
    The application of all or some of said layers can be done by casting, knife coating, spraying, coil coating or digital printing.
    In particular, the above-mentioned lanes may be roads, racetracks or taxiways for airplanes, such as runways.
    Further features of the invention will become apparent from the claims, the description and the drawings.
    In the drawings, the subject invention is illustrated schematically in embodiments. Show it

    Fig. 1 shows an embodiment of a pavement marking 2 with a layer structure 1, which is produced by the method according to the invention. If necessary, a first protective layer 3 and a second protective layer 5 are applied to the carrier layer 4 in order to protect the carrier layer from environmental influences. On the underside of the first protective layer 3, an adhesive layer 17 is applied to connect the layer structure 1 with the roadway 15. On the second protective layer 5, an electrically conductive back electrode 6 is applied, which in turn forms a pole for generating an electric field.
    If the carrier material is an electrical conductor, the second protective layer 5 and the back electrode 6 can be dispensed with, since in this case the carrier layer 4 can simultaneously serve as the back electrode 6. In order to insulate the back electrode 6 from the front electrode 9 and, if necessary, to increase the electric field strength in the light-emitting layer 8, a dielectric layer 7 is applied to the back electrode 6. This dielectric layer 7 may be constructed so as to serve as a reflector for the light generated in the light-emitting layer 8.
    If the carrier layer 4 simultaneously forms the back electrode 6, the dielectric layer 7 can be designed such that it also serves as the second protective layer 5 for the carrier material.
    The light emitting (or active) layer 8 is used for the actual generation of the light for the lane marking. The light-emitting layer 8 is applied to the dielectric layer 7. The light-emitting layer 8 can be applied both over the entire surface of the lane marking, as well as only partially, if not the entire surface should shine or must.
    On the light-emitting layer 8, an electrically conductive front electrode 9 is applied. This layer serves as a second pole for generating an electric field. The front electrode 9 is translucent, so that the light generated in the light-emitting layer 8 can shine through the front electrode 9. δ 50460 Ag / Fl Christoph Thalner
    Finally, a light-permeable protective layer 10 is applied, which serves to protect against environmental influences. Finally, the actual marking layer 11 is applied, which is designed to be reflective and with increased static friction properties, so that recognition of the road marking is ensured even in the event of a power failure, and the road users do not recognize any changed properties. For the electrical operation of the pavement marking electrical contacts 12,13 on the flywheel electrode 6 and the front electrode 9, and an AC voltage source 14 are provided.
    Fig. 2 shows another embodiment of a pavement marking with a layer structure according to the invention. In this exemplary embodiment, the back electrode 6 simultaneously serves as the carrier layer 4. A second protective layer is unnecessary, and the dielectric layer 7 can be applied directly to the carrier layer 4 serving as the back electrode. A thinner layer structure is the result.
    FIG. 3 a shows a road marking 2 according to the invention with a layer structure 1 according to the invention, which is attached to the roadway 15 via an adhesive layer 17. The lane marking is slightly raised, which increases the awareness of the road users, as soon as they run over the lane marking. The increase is so low that no risk to road users can arise.
    3b shows a further embodiment of a pavement marking according to the invention with a layer structure 1 according to the invention. In this exemplary embodiment, a groove 16 is first of all milled into the roadway 15. In this groove 16, an adhesive layer 17 and the layer structure 1 is introduced. Thereafter, the groove 16 is closed flush with asphalt or other filler. 9 50460 Ag / Fi Christoph Thalner
