Definitions
- UV irradiation device with additional monochromatic radiation source UV irradiation device with additional monochromatic radiation source
- the present invention relates to a process for UV crosslinking of paint layers.
- the invention also relates to an irradiation device for carrying out the method.
- UV crosslinking hardens and dries lacquers applied to substrates.
- the paint remains flowable until crosslinking and can be abruptly solidified after application to a substrate.
- the UV radiation source used in most cases is a radiation source which emits both UV radiation and visible light and a high percentage of infrared radiation (IR radiation).
- IR radiation infrared radiation
- the high proportion of IR radiation leads to high process temperatures which can damage the substrates to be irradiated.
- a radiation source may be called a high-pressure Hg lamp.
- critical temperatures are often achieved with conventional irradiation. For example, in the known under the name ABS plastic material temperatures of 85 ° C should not be exceeded.
- components mounted on the exterior of vehicles should have a metallic appearance.
- these components are often based on plastic substrates which are given a metallic appearance by coating.
- a lacquer layer (basecoat) is first applied to these substrates, inter alia to smooth the surface.
- the PVD layer is covered by means of a UV-curing substantially transparent lacquer (topcoat) in high gloss or a matting.
- topcoat and PVD layer have different thermal expansion coefficients.
- embrittlement with increased cross-linking thus has the consequence, for example, of a temperature change or mechanical stress, that if the underlying material changes its expansion in accordance with a different thermal expansion coefficient, the lacquer no longer adheres to this material and thus flakes off.
- such a brittle paint can also lead to fatal flaking of the paint.
- the present invention is therefore based on the object to provide a paint having a good micro scratch resistance without realizing the disadvantage of embrittlement.
- the invention is also based on the object of providing a method according to which a lacquer layer can be produced which has a good micro-scratch resistance without realizing the disadvantage of embrittlement.
- the method can be carried out in particular under atmospheric conditions, i. no inert gas atmosphere is necessary.
- the object is achieved by connecting an additional monochromatic UV-C lamp (for example in direct irradiation to the object) to the high-pressure Hg lamp already known from the prior art after a defined time.
- FIG. 1 shows a device 1 for crosslinking UV-coated substrates which are arranged on a spindle 3.
- the spindle slowly rotates clockwise.
- a high-pressure Hg lamp 5 is arranged, which emits a broad radiation spectrum, including UV, visible and IR radiation, indicated by the arrow end provided with crossed hatching.
- This radiation is incident on a cold light mirror 7 rotated by 45 ° to the main radiation direction.
- the cold light mirror 7 essentially reflects the UV light downwards in the direction of the spindle and transmits substantially visible light and IR radiation.
- UV light which is incident from the high-pressure Hg lamp 5 on the surface of the painted substrates arranged on the spindle is absorbed by the lacquer layer and causes the polymers in the lacquer to crosslink substantially uniformly and to a certain degree.
- the substrates of the UV radiation of the Hg lamp are exposed for about 120 seconds. Switching on and off of this radiation takes place by switching on and off the Hg lamp or by rotation of the cold light mirror 7 in or out of the beam path of the Hg lamp, preferably about an axis 9, which is located outside the beam path.
- FIG. 1 shows a UV-C lamp 1 1 which emits substantially monochromatic radiation of the wavelength 254 nm in the direction of the spindle surface.
- the substrates are additionally exposed to this radiation but with respect to the broadband radiation of the Hg lamp 5 at a later time.
- This can be achieved, for example, with a rotating spindle such that the UV-C lamp 1 1 is switched on and off very often and in such a way that no UV-C radiation is incident on the spindle for 50% of the time.
- Another possibility is to provide a shutter between spindle and UV-C lamp, which absorbs the radiation of the UV-C lamp.
- a periodically inserted into the beam path of the UV-C lamp mirror There may also be several mirrors e.g. to be assembled into a rotating mirror drum.
- the monochromatic UV-C radiation has only a very small penetration depth into the paint surface and therefore crosslinks only the surface area of the paint additionally. On This creates a very hard and thus very resistant to micro-scratch surface without this entire coating layer would be embrittled.
- the use of the cold light mirror for the radiation of the mercury lamp, preferably as described above in combination with the UV-C lamp is then particularly advantageous if the non-crosslinked paint has a temperature which is well above room temperature. This is the case, for example, if, after application of the lacquer, it is exposed to intensive IR irradiation in order to accelerate the escape of any solvents. In this case, 70 ° C is rapidly reached by the IR pretreatment. Beauching with the unfiltered radiation of the Hg lamp would raise the temperature of the paint above the permitted level. By using the cold light mirror, this danger does not exist. Due to the increased starting temperature, the crosslinking speed is accelerated. Due to the lack of visible and IR radiation, however, there is no excessive heating.
- a component has been disclosed whose surface is at least partially covered by a coating, wherein the coating comprises a PVD coating arranged between a first lacquer layer and a second lacquer layer and the first lacquer layer forms a basecoat layer on the surface and the second lacquer layer comprises a topcoat layer forms a topcoat thickness on the PVD coating, wherein at least the topcoat layer was prepared with UV-curing lacquer.
- the topcoat layer has a lower degree of crosslinking induced by UV light than in the part of the tocoate layer adjoining this area
- the degree of crosslinking of the topcoat layer is highest at the interface with the environment.
- the basecoat layer may also be made with UV-curing lacquer.
- the PVD layer may comprise two layers and preferably be made of a plurality of PVD layers. It has been disclosed for producing a metallic finish component with the following steps:
- the light of the Hg lamp before it acts on the topcoat preferably the light of the Hg lamp before it acts on the topcoat, filtered by means of a cold light mirror.
