Definitions
- the invention relates to a method for Mel rtiklacktechnik of substrates using Tahlungshärbare Beschichnrngsmi tel.
- the method can advantageously be used in vehicle and industrial painting, preferably in vehicle repair painting.
- UV technology has long been state of the art in coating and hardening.
- coating compositions curable by means of high-energy radiation are also used here, e.g. the very short curing times, the low solvent emissions of the coating agents and the very good hardness of the coatings obtained from them.
- the use of heat-curable binders or coating agents can combine UV radiation with thermal treatment.
- the warming or ernischen treatment can be realized for example by means of hot air, heating plate or infrared radiation (IR radiation).
- the coating can be dried with IR radiation before the UV irradiation and thus different properties, such as the interlayer coating, weather resistance and optics can be improved in this way radiation-curing lacquer required flash-off times can be reduced.
- the flash-off phase is considerably shortened.
- a subsequent LR radiation is advantageous, for example, if the coating contains, in addition to the radiation-curable binders, further binders which crosslink via an additional mechanism. In such a case, complete curing can be achieved quickly with the subsequent IR radiation.
- a combination of UV and IR radiation during the curing process in the broader sense can be realized, for example, by continuously moving the UV radiation source or LR radiation source and / or the object to be irradiated past one another or by discontinuously UV radiation source and IR radiation source are placed alternately in front of the object to be irradiated.
- a disadvantage of the described procedures is that, on the one hand, at least two drying or hardening zones (UV zone and LR zone) to be passed through are present in the continuous process and UV and IR zones must be separated from one another, for example by glare protection, and on the other hand in the discontinuous mode of operation, UV and IR radiation sources, depending on the number of desired radiation intervals in front of the object to be irradiated, have to be exchanged mutually, the UV lamp generally not being operated during the IR drying phase.
- Radiation sources especially UV lamps, generally have a time-delaying effect on the entire painting process. Especially when using the discontinuous procedure e.g. In paint shops, the vehicle throughput and thus ultimately the profitability of the workshop can be impaired.
- the object of the invention was therefore to provide a process for multi-layer coating using at least partially curable coating compositions, which enables UV radiation and IR radiation to be combined in a simple, economical and time-saving manner without curing an undesirably high level equipment and thus costly effort to have to operate.
- the object is achieved by the method for forming an object of the invention Multi-layer coating by applying one or more fillers and / or further coating agent layers to an optionally pre-coated substrate and then from a top coat layer from a basecoat / clear coat structure or from a pigmented single-layer top coat, wherein at least one of the layers of the multi-layer structure is produced from a coating agent which is at least partially curable by means of high-energy radiation and this layer (s) are irradiated with UV radiation and IR radiation, which is characterized in that a UV radiation source is used for the irradiation with UV and IR radiation, which has an LR radiation component in its emission spectrum and that by alternating upstream of a UV filter and an IR filter and / or alternately upstream and omitting a UV filter or an IR filter in front of the UV radiation source, at least two radiation intervals are formed, during which different m it is irradiated with UV radiation, IR radiation or simultaneously with UV radiation and IR radiation.
- UV filters and IR filters When working according to the invention, it is possible to use UV filters and IR filters alternately. It is also possible to work with either a UV filter or an IR filter and alternately omit it so that UV and IR radiation are irradiated simultaneously. Both working methods can be combined with one another, so that alternating radiation intervals with UV radiation, IR radiation or together UV and IR radiation are formed.
- UV radiation sources that can be used in the method according to the invention and modified with an upstream filter can thus be used quickly and easily as pure LR radiators.
- UV radiation sources can be used as the UV radiation source, provided that they have an LR radiation component in their emission spectrum.
- Such UV radiation sources are known to the person skilled in the art and are generally accessible.
- the IR radiation component required in the emission spectrum of the UV radiation source is preferably a radiation component in the region of the short-wave IR radiation. This is the wavelength range from about 700 to about 2500 nm.

Lamps of between 5 and 200 cm in length are used. Depending on the specific application and the required radiation energy, the lamp and reflector geometry are matched to one another in the usual way. The respective lamp output can vary, for example, between 20 and 250 W / cm (watt per cm lamp length). cm used.

- the UV flash lamps for example, have an illuminance of at least 10 megalux, preferably from 10 to 80 megalux, per flash discharge.
- the energy per flash discharge can be, for example, 1 to 10 kJoules.
- the UV radiation sources which can be used in the method according to the invention are modified by connecting a UV or IR filter upstream of the UV radiation source.
- a UV filter is to be understood as a filter which essentially does not contain any radiation in the Wavelength range of UV radiation, ie in particular in the range of about 180 to 380 nm, transmits, but is transparent to IR radiation.
- An IR filter is to be understood as a filter which essentially does not transmit any radiation in the wavelength range of the IR radiation, in particular in the range from about 700 to 2500 nm, but is transparent to UV radiation.

- Application is carried out in the usual way, for example by means of spray application.
- a drying phase or heating phase with LR radiation follows after a possibly allowed flash-off phase.

- the LR radiation is realized by, as already described above, a UV filter connected upstream of the UV radiation source used and irradiated accordingly. During this irradiation interval, the
- the irradiation time with LR radiation can be, for example, 1 to 20 min. If a UV flash lamp is used as the UV radiation source, the LR irradiation can also be carried out by triggering several flash discharges. The irradiation time depends, for example, on the type and amount of the solvents still present in the coating after application. Depending on the radiation duration and power of the radiation source, temperatures of, for example, 40 to 200 ° C. can be reached on the substrate surface. The settings should preferably be made so that temperatures of, for example, from 40 to 100 ° C can be reached on the substrate surface. When the desired temperature of the substrate surface has been reached or the intended exposure time has expired, the UV filter is removed. After removing the UV filter, UV crosslinking begins immediately in the case of continuously operating radiation sources. In the case of discontinuously operated UV flash lamps, the desired UV flashes are triggered after the UV filter has been removed.
- the exposure time to UV radiation can be, for example, in the range from 1 millisecond to 400 seconds, preferably from 4 to 160 seconds, depending on the number of flash discharges selected.

If, in addition to the binders curable by means of UV radiation, there are also binders in the coating agent which crosslink or harden according to an additional mechanism, there is the further advantage that a certain degree of crosslinking already takes place as a result of the LR radiation, which leads to improved stability, for example leads.
