Definitions

  • the invention relates to a method for producing a coating by means of electromagnetic radiation on a moving in the conveying direction quasi-endlessly funded, in particular band-shaped, flexible material band.
  • Coatings of surfaces not only play a role in the aesthetic effect, but also serve, for example, to protect a certain object against external influences, such as e.g. against light radiation, water, heat and mechanical effects to make them more resistant.
  • the coating can impart physical properties which the body to be coated as such does not possess, e.g. electrical conductivity or magnetizability.
  • quasi-endless conveyed flexible material belts such as e.g. of metal strips, plastic films, composite material systems and laminates, which are conveyed by rollers or stacks, for example.
  • Quasi-endless coated metal sheets are being processed in huge quantities in the automotive industry and also for the production of household appliances (the so-called white goods) and also for the manufacture of aircraft and watercraft and of cladding for the construction industry.
  • the steel sheets are primarily bare, galvanized or nickel-plated (steel) sheets with thicknesses in the range of a few tenths of a millimeter and over one millimeter.
  • Such sheets are Rolls, so-called “coils” wound before they are continuously fed to a specific forming or stamping process.
  • the sheets already receive a corrosion protection coating and / or a primer or a primer coat on the "coil".
  • the coating of these metal strips is carried out prior to the process step of bending, embossing, etc., in which the sheet is finally brought into the desired shape for rationalization reasons.
  • at least one coating agent is usually rolled on a first station of this system or applied to the metal strip by another technique.
  • Such coating compositions are usually applied in the liquid state, but sometimes also as a powder coating.
  • the metal strip Since the coating material must be completely dried or crosslinked before the subsequent process steps, the metal strip is subsequently fed to a furnace, which often operates on the principle of circulating air drying. In this furnace, the coating agent is heated together with the entire metal sheet of the metal strip, so that the coating agent dries and / or crosslinked. Due to the strong heating of the metal strip cooling of the metal strip is necessary following the drying process. Since the metal strip is subjected to bending, embossing and welding processes frequently after the coating process, the quality of the dried or crosslinked coating composition is particularly stringent. So this may not peel off when bending or embossing. Furthermore, the coated metal strip must remain weldable.
  • the heat energy necessary for drying or crosslinking of the coating agent is transmitted inductively, ie, transmitted to the metal strip by electromagnetic coupling. That so heated metal strip releases the thermal energy by heat conduction to the coating agent, whereby it is dried or crosslinked.
  • the entire metal strip must be heated from the ambient temperature outside the plant at least to the temperature required for drying or crosslinking of the coating composition.
  • an inductive heat transfer system with thin metal strip thicknesses and / or large coating thicknesses (i.e., depending on their specific heat capacity), it is necessary to heat the metal strip even above the temperature required for drying or crosslinking. That is, for a coating agent requiring a temperature of 180 ° C for cross-linking, the metal tape must be inductively heated to about 250 ° C to produce a sufficient temperature gradient between metal tape and coating agent such that the coating agent will be in an acceptable time can be dried or crosslinked.
  • the metal strip unwinding from a roll is guided through the individual stations of this plant, for example at a conveying speed of 120 m / min. Due to such high conveying speeds and the resulting shorter interaction time during drying or cooling of the metal strip, the individual stations, i. the drying oven and the cooling station, considerable length expansions, which can be up to 100 m.
  • thin-film structures on large-area, thin quasi-endless conveyed material bands or carriers are becoming increasingly important in various fields of technology.
  • thin-film transistor structures as used in particular in liquid crystal display devices, and other thin-film systems for display units, such as plasma displays.
  • Other technically and economically important thin-film structures are the separator structures of electrochemical elements, in particular primary or secondary elements based on lithium (lithium batteries and lithium-ion batteries, etc.) and highly differentiated membrane systems for the separation of substances and energy, for example in fuel cells.
  • This object is achieved according to the invention by a method for producing a coating according to the features in the characterizing part of claim 1 and by a device according to the features in the characterizing part of claim 15.
  • the present invention relates to a method for producing a coating of quasi-endless, conveyed and in the conveying direction moving Materialbändem which are provided with a coating agent which is at least partially dried and / or crosslinked at least partially by means of electromagnetic radiation, wherein the substantial active component of electromagnetic radiation in the wavelength range of the near infrared.
  • the present invention relates to a method for producing a coating or a thin layer structure from a band-shaped, flexible, in particular quasi-endless, carrier having at least one functional coating bonded to the carrier, which has a thickness which is in particular of the order of thickness of the carrier comprising the steps of forming a starting layer structure by coating a coating agent on the carrier and irradiating the carrier provided with the coating agent with electromagnetic radiation having a near-infrared active power to form the functional coating of the Coating agent while being combined with the support, including drying and / or thermal crosslinking.
  • An important application of the proposed method is in particular the drying and / or crosslinking of a corrosion inhibitor or primer or a primer for a subsequent coating, especially on the surface of a bare, galvanized or nickel-plated steel sheet, especially for the automotive or household appliance production (coil coating).
  • the coating agent in the initial state is a powder or liquid paint layer, which is dried or crosslinked for intermediate or final coating.
  • the inventive method is characterized by potentially high productivity, simplicity and reliability with substantial exclusion of damage to the coating (s) and / or the carrier.
  • the coating on a strip of material with particularly short irradiation times, preferably in less than 30s, preferably less than 10s, more preferably less than 5s, especially 2s and therefore, compared with a conventional coating or coil -Coating process, especially fast to produce. Due to the short treatment or irradiation time, the material band is thermally stressed little. This makes it possible to coat thermally sensitive materials such as thermoplastics with coating agents that require temperatures for crosslinking, which are higher than the damage temperature of the material band. Thus, it becomes particularly possible with the method according to the invention to coat material strips whose coating was previously impossible or only with great technical difficulties because of their thermal sensitivity.
  • changes in the material structure and / or changes in material properties can be avoided by applying the method according to the invention, which was often not possible in conventional methods, or only with considerable extension of the time required to carry out the method.
  • strips of material may be coated whose microscopic structure changes with high heat input (which may reduce their mechanical strength properties or cause microstructural changes in the material), e.g. Aluminum or alloys, or strips of material whose materials segregate, e.g. Composites.
  • the short irradiation times mean that in many cases a higher quality of the coating can be achieved. Also, the energy and cost required to produce a coating can be significantly reduced.
  • the intensity maximum or the spectral composition of the electromagnetic radiation is adapted to the absorption and transmission properties of the coating composition and optionally the material band according to a preferred embodiment.
  • the wavelength of the maximum intensity and / or the spectral composition of the electromagnetic radiation is selected so that the coating agent the radiation energy absorbed substantially uniformly over its layer thickness, whereby an impermissible thermal stress on the carrier as well as individual areas of the coating is avoided. It can thereby be achieved that the coating agent is uniformly and at least partially heated and / or crosslinked directly by the radiation within the shortest possible time.
  • the spectral composition of the electromagnetic radiation is adjusted by at least one filter.
  • the intensity maximum of the electromagnetic radiation can preferably be adjusted so that relatively little radiation is absorbed in the band of material in order to avoid useless heating thereof.
  • an energy transfer by heat conduction which takes place slowly in comparison to energy transfer by radiation, can be greatly reduced to the material band in contact with the coating agent.
  • a clear temperature gradient in the material band and thus an energy separation between the material strip and the coating composition to be dried or crosslinked are achieved. It can be achieved in comparison to conventional methods significantly higher efficiency and the amount of energy required to carry out the process according to the invention can be significantly reduced compared to conventional methods, depending on the material properties, such as the specific heat capacity, the thickness of the material strip or the coating agent because comparatively little heat energy is transferred to the material band. This effect plays an important role especially for materials with a particularly high heat capacity, such as sheet steel, since these materials consume a large amount of energy absorb.
  • the heating of the sheet of 250 ° C as is the case for example in a conventional inductive method, be reduced to 200 ° C. Accordingly, this means a reduction of the energy required for drying or crosslinking of the coating agent by one fifth. For thicker materials, larger temperature differences, ie energy savings, are possible.
  • the costs of the device or system required for this purpose are significantly reduced, since due to the significantly shorter compared to conventional drying or curing times and the necessary for drying or curing distance at constant delivery speed is significantly reduced. In particular, infrastructure savings are particularly noticeable.
  • reflections at the interface between the coating agent and the strip of material can bring about a renewed irradiation of the coating agent and thus the efficiency of the energy transfer to it can be increased.

  • the intensity maximum of the electromagnetic radiation is adapted to the absorption and / or transmission properties of the material strip such that the electromagnetic radiation at least partially penetrates the material band.
  • This is particularly useful when applied on both sides of the material tape coating agent.
  • certain coating compositions / material band combinations may also be used the drying or crosslinking are carried out in such a way that the electromagnetic radiation used for drying or crosslinking also penetrates the material band in addition to the coating agent which is applied to the material band side facing the radiation source. In this case, preferably substantially no radiation energy is absorbed in the material band.

  • the coating agent applied to the material band on both sides is dried or crosslinked substantially simultaneously on both sides of the material band.

  • the radiation source can be protected from the volatile material and flammable components leaving it by the material band and / or one or more further processing steps can be carried out simultaneously with the irradiation process on the side of the material band on which the coating composition is applied the coating agent and / or the material band are performed without hindering the irradiation process.
  • the drying or crosslinking processes of the coating agent are essentially thermally conditioned. This means that when drying a water or solvent coating agent the solvent with the electromagnetic radiation from the wavelength range of the near infrared energy is transferred to separate the solvent from the coating agent.
  • energy is transferred to the coating agent, which in the form of heat energy is used to effect the formation of polymer chains.
  • a certain temperature of the coating agent is required for this, so that the crosslinking process takes place.
  • the drying or crosslinking of the coating agent can be either completely or only partially by the electromagnetic radiation whose essential active component is in the wavelength range of the near infrared.

Also, the drying or crosslinking can be supported at the same time or offset in time with the above-mentioned irradiation by at least one additional radiation source, in particular with an active component in another wavelength range, and / or by at least one other energy or heat source. In order to achieve particularly short drying times or particularly short irradiation periods, electromagnetic radiation with a high power density is preferably used.
  • Typical power densities characteristic of the method according to the invention are in particular above 100 kW / m 2 , preferably above 200 kW / m 2 and particularly preferably above 500 kW / m 2 .

  • Such a wavelength range of the electromagnetic radiation has proved to be particularly effective for a highly effective polymer formation or polymer crosslinking of the coating compositions used for coating material strips.
  • the invention When using wavelengths that take into account the specific absorption and / or transmission or reflection properties of the material strip and / or the coating agent, and / or when using the for the specific material band and / or coating means to be determined optimal power densities, the invention preferably allows the above short irradiation periods in a preferred embodiment.
