Definitions

  • the invention relates to a device for masking areas of a vehicle during the painting process.
  • the invention also relates to a method for producing and recycling operating equipment of this type and a method for masking areas of a vehicle during the painting process with such operating equipment.
  • a cathodic dip coating (KTL) is applied to the body shell as a corrosion protection layer.
  • B. is baked in a dryer at temperatures up to 220 degrees Celsius.
  • a filler is first applied to compensate for the surface and to protect against stone chips.
  • a base coat for coloring and effects
  • a clear coat to protect against external influences.
  • the actual painting process carried out after the KTL coating is carried out at temperatures of up to approx.
  • the window panes (windshield, rear window, fixed side windows) are usually used in large-scale production robot-controlled at the installation site and glued (direct glazing).
  • the pane adhesive is first applied in a bead-like manner all around in the edge region of the window pane before this region is brought into contact with the body flange (window flange) at the installation opening and pressed.
  • the window and the body serve both for stabilization in the sense of a torsionally rigid body and for power transmission in the event of a crash.
  • the window adhesive achieves good adhesion on many different top coats (colors).
  • the structural connection of the window and the body in assembly, where there are painted surfaces, has not been satisfactorily resolved, since the paint structure itself cannot absorb the structural forces, especially in a crash.
  • this process also requires a corresponding masking of the body flange after passing through the KTL painting in order to keep away the paint layers applied in the subsequent painting steps in this area.
  • the masking ensures perfect adhesion of the pane adhesive to the KTL-coated flange.
  • a method for bonding windows in which the body flange with an adhesive tape or with an organic mass, such as. B. a PVC pastisol, is masked.
  • the plastisol is e.g. B. gelled by means of IR emitters or in a PVC oven and achieves a firm consistency.
  • the flange masking is usually manually removed and disposed of, and direct glazing is carried out on the KTL-coated flange.
  • Both the plastisol and the adhesive tape are not recyclable, which means that considerable waste has to be disposed of.
  • the device for masking areas of a vehicle, in which the device consists of a plastic and can be placed on the body flange of vehicle or vehicle module openings in a form-fitting manner on a cathodic dip coating.
  • the design of the masking is specifically designed for the respective area of application and depending on the vehicle type and window cutout.
  • the mask is pressed onto the body flange or slipped over it and completely covers it. This cover is form-fittingly sealed against the penetration of paint in order to prevent the KTL sheet from being coated with paint and to achieve optimal adhesive adhesion for the direct glazing.
  • the resource is from one Plastic is manufactured so that it can be ground in its entirety after use, even in the paint-adhering state, and finally an injection molding process can be added.
  • the equipment is made of a temperature-resistant plastic with a continuous operating temperature of at least 170 ° Celsius.
  • plastics which have the required properties and can be used for injection molding, were only found after detailed practical tests.
  • plastics such. B. polysulfone, poly (aryl ether) ketone, polyamides etc. into consideration, which from the plastics compendium, Vogel specialist book, 4th edition 1996, by Dr. A. Frank, ISBN 3-8023- 1589-8 can be seen.
  • Plastics that are made of fibers such as e.g. Glass, Keflar etc. are reinforced.
  • Glass fiber reinforced polyamide has proven to be the best plastic in terms of procurement costs, recyclability, injection molding (optimum flow behavior) and mechanical properties even at high temperatures, such as those found in the stoving ovens.
  • the advantages described can be demonstrated in particular in the case of equipment whose plastic material is reinforced by fillers in a ratio of 0.1 to 40%.
  • a desirable optimum can be achieved.
  • the object is also achieved by a method for producing and recycling operating means for masking areas of a vehicle during the painting process, in which steps a) the operating means are produced by spraying; b) the equipment is ground in the varnished after each use; c) the resulting powder is fed back to the spraying process for the production of the operating materials as a raw material.
  • the equipment according to the invention is first produced by injection molding and ground in the lacquered state after each use, the resulting powder being able to be used directly again for the production of the equipment.
  • the entire process is simplified by using the special plastics.
  • there is no type-related sorting since the equipment can be ground in the coated state after each use and can thus be delivered to the injection molding as bulk material. In particular, this means that there are no costs for handling and, if necessary, repairing the functionality.
  • the concept according to the invention is also ecological. A mechanical, thermal or chemical operation is not required for the paint stripping, since the equipment according to the invention can be supplied to the injection molding in the lacquered state after grinding.
  • a certain amount of original raw material is preferably added during injection molding in the recycling plant. This can be particularly useful when the quality of the plastic recyclate contaminated with paint is no longer satisfactory. By adding the original raw material, the function of the masking can be maintained with the advantages mentioned above.
  • the amount of original raw material added is preferably about 10%. This slight addition of the original raw material guarantees, in particular, repeated use of the recyclate without sacrificing the mechanical and temperature-resistant properties.
  • the object of the present invention is also achieved by a method for masking areas of a vehicle during the painting process with an item of equipment according to one of the preceding claims, in which the item of equipment is placed on the body flange of the vehicle or vehicle module openings in a form-fitting manner on a cathodic dip coating and is removed after the final painting process.
  • the pane can be glued to the KTL coating, thus avoiding the structural weaknesses in the filler material and in the top coat.
  • Structural bonding of the windows to the body in this way increases the torsional rigidity of the body and improves the derivation of forces in the event of a crash. This fundamentally supports the trend towards lightweight body construction.
  • the device according to the invention can also be used for masking other module bonds, such as, for example, for window bonding.
  • the single figure shows a device 1 for masking a body flange 2, which is encompassed by the device 1 in a form-fitting manner.
  • the body flange 2 is circumferentially attached to an installation opening for a window pane 3, which is provided with a bead of adhesive 4 in its edge region.
  • the flange 2 is only adhered to with the KTL paint, but not with the paint layers applied in the further painting process.
  • the underlying adhesive area is exposed, onto which the window pane 3 is pressed.
  • a structural vulnerability in the form of e.g. B. a filler and topcoat layer between the adhesive 4 and the KTL coated body flange 2 is avoided. This creates a torsionally rigid overall structure in the sense of a lightweight construction with good crash properties.
  • the equipment can be recycled and reused, saving process costs.
