Definitions

  • the invention relates to a method for repairing small Paint defects in paint layers according to the preamble of the claim 1, as it is from the generic JP 1-315 374 (A) emerges as known.
  • JP 1-315 374 A It is known to have minor paint defects, so-called hot spots to be removed using a drill.
  • the remaining largely cylindrical recess is made with a liquid repair lacquer filled, which partially with a mask is covered.
  • the mask points in the area with repair paint filled recess a free space through which a laser light can be directed onto the repair paint.
  • the refinish is made by the energy introduced by the laser light heated and with the lacquer layer surrounding the recess connected.
  • the object of the invention is to develop a method with which, with good optical quality, also powder coatings, in particular Effect powder coatings can be repaired easily and cheaply can.
  • the task is based on a generic method with the characterizing process steps of the claim 1 solved.
  • the recess By inserting the recess with regard to their area and also their depth exactly defined dimensions in the powder coating layer, can then into the recess according to the volume of the Recess dimensioned, in particular the dimensions of the recess corresponding, and at least in some areas connected
  • Packing material made of powder coating and / or a preliminary product of the powder coating can be introduced.
  • the filler introduced is then arranged with the outside of the recess Powder coating layer either completely or only connected in areas, in particular glued.
  • the invention Repairs can therefore be carried out quickly and cheaply.
  • the repair can also be carried out on the production line be made, which is particularly true for vehicles with a cantilever frame according to the space-frame concept, inexpensive is.
  • the repair method points towards one large-area repair with wet paint a low emission, with what an at least lower filter and cleaning effort, as well a low disposal effort, for example associated with the overspray is. This in turn is also a reduction in price associated with the procedure.
  • Figure 1 is a section of a section through a with a Powder coating layer 2 provided substrate 5, which Substrate 5 made of metal, for example. Plastic and / or fiber reinforced Plastic can be made. Furthermore, that Substrate 5 - as shown - be curved. On the substrate 5 are in addition to the powder coating layer, in particular up to 100 ⁇ m thick 2 For example, the usual layers, namely a primer layer 6, an impact protection layer 7 and a filler layer 8 applied. Depending on the application, the powder coating layer of course, be thicker.
  • a faulty location 9 is an oval body in cross section drawn in, which is, for example, a speck of dust 10 can act, when applying the powder of the powder coating on the visible surface 11 of the powder coating layer 2 created and connected with the powder coating.
  • the frame becomes the faulty one Position 9 of the hardened powder coating layer in particular 2 in a narrow area with a cylindrical Provide recess 1. Due to the maximum depth of the powder coating layer 2 introduced recess 1 is in the present Case at the same time eliminates the speck of dust 10.
  • the recess 1 is cutting and in this case in particular by milling or grinding into the powder coating layer 2 introduced. Furthermore, the recess 1 can also be drilled and / or sawn holes and / or burned out by laser and / or are punched out and / or ground. For all types of Introduction of the recess 1 in the powder coating layer 2 is to make sure that the recess 1 in terms of its area, or width B and also with respect to their depth T with exactly defined dimensions and with a given edge contour is introduced into the powder coating layer 2.
  • a powder coating is inserted into the cylindrical recess 1 and / or a preliminary product of the powder coating plate-like filler 3 introduced; i.e. the contour of the The bottom of the packing 2 is flat and the bottom of the recess 1 adjusted.
  • the edges of the packing 3 are the corresponding ones Adjusted edges of the cylindrical recess 1.
  • the one which is at least partially cross-linked before being introduced into the recess 1 Packing body 3 corresponds to the volume of the recess 1 dimensioned and coherent in the sense of a monolith; i.e. the diameter of the monolithically related Packing body 3 corresponds approximately to the width B of the recess 1 and the layer thickness of the filling body 3 is approximately the depth T of Recess 1.
  • this exact dimensioning in can be realized in a simple manner in that the packing 3 molded from a previously produced paint film, in particular is punched out. With at least some effect powder coatings this lacquer film is used to maintain the desired optical properties expediently by electrostatic spraying produced.
  • the packing 3 arranged in the recess 1 is connected to the powder coating layer 2 arranged outside the cutout 1 connected.
  • the connection is preferably made by an adhesive layer 12, which in particular before the introduction of the Filler 3 in the recess 1 along the corresponding Walls of the packing 3 is arranged.
  • the filler introduced into the recess 1 3 and possibly also the adhesive layer 12 heated and / or brought to reaction.
  • the reaction hardens in particular the packing 3 and possibly also the Adhesive layer 12.
  • the reaction is preferably carried out by UV radiation and / or electromagnetic, in particular IR radiation, and / or hot air is introduced and / or maintained.
  • the filler 3 have a volume shrinkage during curing can, it is favorable to fill the body 3 with a volume provided that approximately the volume of the recess 1 plus the volume shrinkage of the packing that occurs during curing 3 corresponds.
  • Such discontinuity on these two edges can For example, with a correspondingly flexible and elastic adhesive layer 12, which is used to connect the packing 3 with the Walls of the recess 1 surrounding it is provided, balanced will.
  • FIG. 5 shows the faulty location 9 for repair according to FIG. 1, the faulty location 9, in particular the bound one and hardened powder coating layer 2 in a narrowly limited range Area provided with a frustoconical recess 21.
  • the cutout has 21 not a cylindrical but a truncated cone Cross section on, with the cone towards the substrate 5 closes.
  • the maximum depth of the Powder coating layer 2 introduced recess 21 at the same time Dust 10 removed.
  • the frustoconical recess 21 is a powder coating and / or a preliminary product of the powder coating, in particular plate-like filler 23 introduced, the Contour of the bottom of the packing 23 and the contour of the Bottom of the recess 21 is adapted.
  • the edges of the packing 23 are in terms of their geometric dimensions and also with regard to their course, for example when they are introduced the recess 21 is not necessarily round, but possibly can also be kidney-shaped, for example, the edges of the recess 23 adjusted.
  • the filler 23 To insert the filler 23 into the recess 21, cover the entire surface with a previously described lacquer film covered.
  • the filler 23 becomes from the covering lacquer film ejected and introduced directly into the recess 21 when ejecting and / or is pressed in.
  • the packing 23 arranged in the recess 21 is connected to the powder coating layer 2 arranged outside the recess 21 connected by the measures listed above.
  • the difference to the embodiment of Figures 2 to 4 here the connection is not made with the help of an adhesive layer 12, but through a direct connection of the material of the filler 23 with the material surrounding it Powder coating layer 2.
  • the connection of the packing 23 with the However, powder coating layer 2 does not have to be along the entire length common area, but can be shared on individual Partial areas may be limited. In the case of fragments 22 formed packing 23 are at the same time the fragments 22 connected in the same way.
