Definitions
- the invention relates to a method for masking surfaces to be matted.
- the invention also relates to a method for matting a surface which comprises such a method for masking surfaces to be matted.
- Methods for masking surfaces to be matted and methods for matting surfaces are known in numerous variations. These known methods can be used, for example, for masking and matting glossy painted surfaces of a vehicle and / or a vehicle component. In order to cover areas of the surface to be matted that are not to be matted, the surface to be matted is masked. In known methods, the masking of the surfaces to be matted is carried out by means of film coating or screen printing processes.
- either water-based lacquer materials or solvent-based lacquer materials are used to mask the surfaces to be matted.
- the use of water-based lacquer materials results in a long production time, since a layer thickness of the masking required to protect the areas that are not to be matted can only be achieved by repeated frequent printing processes (e.g. 20 times).
- solvent-based paint materials the masking layer is laboriously removed after irradiation. Since the solvent-based paint materials are not water-soluble, the solvent-based paint materials can only be removed using chemical aids due to their high adhesive strength.
- a method for matting a surface with the following steps is known from EP 0 672 500 A2: providing a workpiece with a surface to be matted, masking the surface to be matted in order to cover areas not to be matted, and irradiating the surface by means of sandblasting so that unmasked areas are matted.
- the surface to be matted is masked by means of a pad printing process with water-soluble peelable lacquer.
- a method for matting a surface with the following steps is known from DE 199 15948 A1: providing a workpiece with a surface to be matted, masking the surface to be matted in order to cover areas not to be matted, and irradiating the surface by means of sandblasting so that no masked areas are matted, the surface to be matted being masked by means of a screen printing process with water-soluble peelable lacquer.
- the invention is based on the object of providing a method for masking surfaces to be matted and a method for matting surfaces with such a method for masking surfaces to be matted, which enables the masking to be applied simply and quickly to the surfaces to be matted Surface as well as a simple and quick removal of the masking from the matted surface.
- the first lacquer material is designed in such a way that the first layer can be easily removed from the surface.
- the second lacquer material is selected and applied in such a way that the second layer has a high resistance to a jet of abrasive material, which is higher than the resistance of the first layer.
- the easily removable first layer advantageously acts as a “separating layer”, which enables the entire masking to be removed easily, and the second layer on top with the higher resistance to a jet of abrasive material acts as a “protective layer” during irradiation Surface with a jet of abrasive material and can be applied with at least one application process. By masking the surface to be matted, various optical effects can be created.
- a method for matting surfaces is proposed with the following steps: providing a workpiece with a surface to be matted, areas of the surface that are not to be matted being masked with such a method for masking surfaces to be matted, and irradiation of the surface with a jet of abrasive material, so that unmasked areas of the surface are matted.
- the first lacquer material can be a water-based lacquer.
- the second paint material can be a solvent-based paint.
- the application of the first layer of the water-based and thus water-soluble varnish enables the entire masking to be removed easily, since the separating layer and thus also the second layer of solvent-based varnish applied over it is easier with what water is removable.
- the solvent-based paint can be cured, for example, by an additional drying process under UV light or simply by air drying or by other suitable methods.
- a high second layer thickness of the second layer which is greater than the first layer thickness of the first layer can be achieved in at least one masking application.
- the second layer thickness can, for example, be a factor of 2 to 4 thicker than the first layer thickness.
- the masking of the first layer and / or the second layer can take place by means of a pad printing method.
- a silicone pad of a pad printing system can be partially coated with the first paint material or the second paint material, the coated silicone pad printing the at least one non-matt area of the surface with the first paint material or the second paint material.
- the silicone tampon is partially coated with the first lacquer material to apply the first layer, and is partially coated with the second lacquer material to apply the second layer.
- the pad printing process has the advantage that an automated masking of convex, flat and concave surfaces is possible, which results in lower process costs.
- the second layer thickness of the second layer can be applied so high that the second layer is not completely removed during irradiation with the abrasive material and the areas of the surface that are not to be matted underneath are not matted.
- the first layer and the second layer can be removed and / or peeled off from the surface after being irradiated with the abrasive material.
- the entire masking can be removed from the matted surface with pure water or with water and light chemical additives. This has a beneficial effect on occupational safety and environmental protection.
- the simple cleaning makes it possible for the cleaning process to be carried out automatically and thus faster than by hand.
- Fig. 2 is a schematic flow diagram of an embodiment of a method according to the invention for matting upper surfaces
- FIG. 3 shows a schematic sectional illustration of a workpiece with a surface to be matted, which was masked with the method for masking surfaces to be matted from FIG. 1.
- the illustrated exemplary embodiment of the inventive method 100 for masking surfaces 3 to be matted includes a step S100 in which a workpiece 1 with a surface 3 to be matted is provided.
- step S110 at least one area 5 of the surface 3 that is not to be matted is masked with a first layer S1 of a first lacquer material.
- step S120 the same area 5 not to be matted is masked with a second layer S2 made of a second lacquer material.
- the first lacquer material is designed in such a way that the first layer S1 can easily be removed from the upper surface 3.
- the second lacquer material is selected and applied in such a way that the second layer S2 is highly resistant, which is higher than the resistance of the first layer S1.
- An exemplary embodiment of a masked workpiece 1 is shown in FIG.
- the illustrated exemplary embodiment of the method 200 according to the invention for matting surfaces 3 comprises, in addition to steps S100 to S120 of the method 100 according to the invention for masking surfaces 3 to be matted, a step S200 in which the masked surfaces to be matted Surface 3 is irradiated with a jet of abrasive material, so that the non-masked areas 7 of surface 3 to be matted are matted.
- the irradiation of the surface 3 to be matted that is carried out in step S200 is carried out until a desired degree of matting is reached.
- a step S210 the first layer S1 and the second layer S2 are removed and / or peeled off from the matted surface 3 after being irradiated with the abrasive material. Pure water or water and light chemical additives are preferably used to remove the masking.
- the workpiece 1 shown in the excerpt shown as an example has a colored lacquer layer as surface 3 to be matted with three areas 5 not to be matted, which are masked by the method 100, and with two areas to be matted 7, which are not masked.
- a second layer thickness D2 of the second layer S2 in the illustrated embodiment is at least a factor of 2 thicker than a first layer thickness D1 of the first layer S1.
- the second layer thickness D2 of the second layer S2 is applied so high that the second layer S2 is not completely removed during the irradiation with the abrasive material and the areas 5 of the surface 3 which are not to be matted underneath are not matted.
- a water-based paint is used as the first paint material and a solvent-based paint with a higher resistance is used as the second paint material.
- Masking of the first layer S1 and / or the second layer S2 preferably by means of a pad printing process.
- a first silicone pad of a multicolor pad printing system is partially coated or printed with the first lacquer material.
- the at least one area 5 of the upper surface 3 that is not to be matted is then coated with the first lacquer material by the silicone pad.
- a second silicone pad of the multicolor pad printing system is partially coated with the second lacquer material.
- the at least one area 5 of the surface 3 that is not to be matted or the applied first layer S1 of the second silicone pad is coated or printed with the second lacquer material. Not only flat surfaces 3 to be matted, but also convex or concave surfaces to be matted can be masked by the pad printing process.
