Definitions
- the present invention relates to a method and an apparatus for manufacturing of hardened, in particular radiation-hardened lacquer layers on one Substrate surface.
- Paint layers are used today using the radiation curing method manufactured.
- Radiation curing uses an easily processable mixture of reactive feedstocks and additives by exposure in a three-dimensional, mechanically stable polymer network transferred.
- This is the reactive paint formulation first applied to the associated substrate and in a second Step by optical exposure, preferably with a UV exposure device, or by means of Cross-linked electron beam hardening. Examples of this are those optically via photoinitiators started polymerizations of low-viscosity paint formulations reactive monomers, oligomers and prepolymers, for example the radical one Acrylate polymerization or cationic vinyl ether or epoxy polymerization, or the optical crosslinking of linear polymers with reactive side chains.
- An object of the present invention is therefore an apparatus and a method provide with the help of a simple and comparatively fast uniform layer of lacquer produced without the problems described above can be.
- At least one crosslinking reaction understood that the crosslinking reaction is not yet running at this point in time, but that a condition is created in the at least one reactive coating formulation, on the basis of which the crosslinking reaction will take place after a certain period of time.
- the method according to the invention is accordingly distinguished in particular by this from that the at least one crosslinking reaction in contrast to from the prior art painting processes known in the art now before application of the paint formulation is initiated on the associated substrate surface.
- This allows one homogeneous initiation of the crosslinking reaction and thus avoids an uneven Networking, for example of complex shaped three-dimensional substrates, which is often a considerable problem with conventional painting processes Effort needs to be made to actually paint each spot Treat the surface equally in order to create an even layer of lacquer receive.
- Step a) the crosslinking reaction in the at least one reactive coating formulation optically initiated. This is preferably done by UV exposure or electron radiation the at least one reactive paint formulation. Included in one Reactive lacquer formulation that can be used must have a crosslinking reaction optically can be activated so that from a low-viscosity paint formulation a highly viscous, mechanically stable paint layer can arise.
- the at least one reactive coating formulation preferably comprises at least one photoinitiator.
- This at least one photoinitiator can interact with appropriately irradiated light in such a way that it is able to initiate the crosslinking reaction in the at least one coating formulation.
- this are the polymerizations of low-viscosity paint formulations of reactive monomers, oligomers and prepolymers started optically via photoinitiators or the optical crosslinking of linear polymers with reactive side chains. Radical acrylate polymerization and cationic vinyl ether or epoxy polymerization can be mentioned here, among others.
- the still low-viscosity paint formulation is now irradiated with light, preferably with UV light, before being applied to the substrate surface in question.
- a homogeneous flooding with UV light can be carried out on the ejection nozzle for the reactive paint formulation or in the corresponding feed line by exposing from different sides or the feed line is designed as a UV light guide.
- UV light guide It is also advantageous here that, with these small dimensions and geometries, it is not only possible to work with conventional UV lamps, but also with UV lasers. The latter are preferably used due to their simple beam guidance and the possibility of optimally adapting the laser wavelength to the absorption of the photoinitiator system contained in the reactive coating formulation, as described, for example, in J.-P. Fouassier, Photoinitiation, Photopolymerization and Photocuring, Hanser Publishers, Kunststoff, 1995.
- the crosslinking reaction in the at least one reactive coating formulation initiated thermally.
- Provisions are preferably made in the method according to the invention which make it possible to kinetically control the crosslinking reaction in the reactive coating formulation which is to be initiated, initiated and ultimately run; the induction period is decisive for this, as in J.-P. Fouassier, Photoinitiation, Photopolymerization and Photocuring , Hanser Publishers, Kunststoffer Publishers, Kunststoff, 1995, p. 165, Figure 5.1.
- the corresponding kinetic setting of the crosslinking reaction prevents the exposed reactive coating formulation from being crosslinked before it hits the corresponding substrate surface and before it is distributed there, preferably homogeneously, and thus changes into a state which uniformly distributes the coating formulation onto the substrate surface would complicate considerably.
- the time period between the initiation of the crosslinking reaction and its actual use must be at least so long that the still low-viscosity reactive coating formulation reaches the substrate surface and can run there to a film of the desired homogeneity. Only then does the crosslinking reaction begin, which ultimately results in a hardened lacquer layer. This has all mechanical properties, such as scratch resistance and elasticity, as well as good chemical resistance, as are known from the radiation-hardened lacquer layers produced by the previous methods.
- care is preferably also taken to ensure that the initiation, for example the UV exposure of the coating formulation, is carried out immediately, ie approximately a fraction of a second before the coating formulation is applied to the substrate.
- the coating formulation is therefore only exposed shortly before or after leaving the application unit, and it is furthermore preferably ensured that the application unit is at a short distance from the substrate surface.
- the temperature of the reactive coating formulation is preferably set in such a way that that the crosslinking reaction, even after it has been initiated, is not immediate starts delayed.
- the reactive paint formulation is prepared in such a way that the necessary application viscosity is maintained, for example due to higher proportions of reactive thinners. The latter also grant in the case of lowers Temperatures a homogeneous distribution of the paint formulation on the corresponding substrate surface.
- a sufficiently slow crosslinking reaction is used.
- the reactive lacquer formulation is selected or synthesized in such a way that the crosslinking reaction to be triggered therein proceeds slowly enough that after its initiation there is sufficient time for the still low-viscosity lacquer formulation to reach the corresponding substrate surface and to form a homogeneous film run.
- An example of such a type of reaction is cationic polymerization. According to J.-P. Fouassier, Photoinitiation, Photopolymerization und Photocuring, Hanser Publishers, Kunststoff, 1995, p. 214, such a system is shown with the use of the diglycidyl ether of bisphenol-A.
- the crosslinking reaction is furthermore preferred by spatial separation of photoinitiators and the reactive paint formulation components to be crosslinked, such as reactive monomers and prepolymers. This is preferably done via nanostructuring of the paint formulation.
- those contained in the paint formulation are preferred Photoinitiators embedded in particles. These particles preferably have a diameter in the nm to ⁇ m range, particularly preferably in the range from 10nm to 100 ⁇ m.
- the crosslinking reaction can be slowed down over time that diffuse the photoinitiators or their cleavage products need out of the particles.
- the photoinitiators are not only embedded in particles, but in latices or dendrimers fixed. The delay time of the crosslinking reaction caused by this is reached now corresponds to the time it takes for the reactive components of the paint formulation such as reactive monomers or oligomers to diffuse into need in the latices.
- the kinetic control of the crosslinking reaction is achieved via a so-called dual-cure application.
- a dual-cure application refers to a resin system that can be cured by two mechanisms, e.g. by physical drying and subsequent UV curing, combined UV and electron beam curing, combination of radiation curing and crosslinking via isocyanates, possibly in combination with alcohols or amines , where the isocyanates may be capped; Combination of radiation curing and crosslinking via epoxides, possibly with amines, which may be blocked, or via acids; Amino resins that are both acid-curable and thermally curable; Oxygen-curing systems, such as, for example, allyl compounds or unsaturated fatty acid esters of epoxides and compounds containing NCO groups, for example, contained in the reactive coating formulation on the corresponding substrate surface in the presence of an optically activatable acid or base, as described, for example, in J.-P.
- the rheological properties during the application phase of the Lacquer formulation dynamically adjusted on the substrate surface.
- Viscosity modifiers rheology additives
- typical Painting problems such as the tendency to run off on vertical surfaces are eliminated.
- step a i.e. initiating the crosslinking reaction in at least a reactive coating formulation
- step b namely the homogeneous application the at least one reactive coating formulation before the crosslinking reaction begins at least one point on the substrate surface
- a further step a ' introduced, namely admixing at least one UV protective agent the at least one reactive paint formulation.
- the UV protection agents preferably dissolved in reactive diluents and shortly after UV exposure the photoinitiator-containing reactive coating formulation and shortly before it Application homogeneously on the substrate surface in preferably turbulent flow added. This type of admixture of UV protection agents is created no impairment of the homogeneity of the UV exposure, i.e. UV radiation curing the paint formulation is not affected while at the same time but guarantees UV long-term stabilization by adding UV protection agents becomes.
- a further step a ′′) is preferably provided between step a) and step b), in which at least one pigment is admixed with the at least one reactive coating formulation.
- the pigment for example for basecoats, is preferably mixed in shortly after the initiation of the crosslinking reaction in the at least one reactive coating formulation, for example by UV exposure of a photoinitiator-containing coating formulation, and shortly before it is applied in a turbulent flow.
- the pigment is preferably dispersed in reactive diluents. Pigments that can be used here, for example, are those described in J.-P. Fouassier, Photoinitiation, Photopolymerization and Photocuring, Hanser Publishers, Kunststoff, 1995, pp.
- the method according to the invention is preferably also used for repair or used to repair layers of paint on a substrate surface.
- Here is used to apply the at least one reactive paint formulation before use the at least one crosslinking reaction at the at least one point in the A handheld spray gun is used on the substrate surface.
- the necessary local Application of the paint formulation on the substrate surface namely exactly on the defective or repaired area guaranteed.
- the use a hand-held spray gun very practical and possible on-site anywhere.
- At least an optical fiber is provided, with the aid of which in the at least one exposure unit generated light in the at least one application unit with the reactive coating formulation is brought into contact.
- This at least one preferably Several light guides, preferably UV light guides, are just in front of the nozzle of the application unit.
- the application unit is preferably around a spray head or around an ESTA bell. Using the light guide homogeneous exposure, especially UV exposure, the reactive paint formulation shortly before leaving the application unit reached.
- the present invention also relates to a lacquer layer which is produced by a process can be produced as described above.
- FIG. 1 the structure of a device according to the invention is shown schematically.
- the at least one reactive coating formulation is made up of one via a feed 5 Storage container passed into the application unit provided with a nozzle 6.
- two light guides 3 and 4 preferably UV light guides appropriate.
- the light guides 3, 4 shown here becomes a homogeneous UV exposure of the reactive coating formulation shortly before leaving the Application level reached directly at the outlet opening of the nozzle 6.
- the Crosslinking reaction in the reactive paint formulation is thus at this point initiated.
- the crosslinking reaction is selected in this way or using other methods kinetically controlled so that at this point, i.e. immediately before the exit opening the nozzle 6 is initiated, but is not yet initiated or is running.
- the Application unit is at a short distance from the relevant, to be painted Arranged substrate surface. This is to ensure that the time period between UV exposure of the reactive coating formulation shortly before the exit opening the nozzle 6 and the impact of the reactive paint formulation on the substrate surface is sufficiently large that the coating formulation which has not yet been crosslinked still has enough time for a homogeneous layer on the substrate surface to get lost. Only then does the crosslinking reaction begin get a hardened paint layer that has all the properties, such as scratch resistance and elasticity, as well as good chemical resistance, as they have of radiation-hardened lacquer layers are known.
