Definitions

  • the invention relates to a surface-coated molded body, in particular a painted motor vehicle body, consisting of one another connected, preformed boards, with an adhesive seam in the Is arranged so that it is present at the junction Trough bridges and that the adhesive seam of surface coatings is covered.
  • British Patent GB-A 1 499 820 describes one surface-coating molded body, in particular a painted Motor vehicle body, consisting of interconnected, preformed boards, with an adhesive seam, possibly based on urethane, is arranged in such a way that it is one at the junction bridging the present trough, the adhesive seam of Surface coatings are covered.
  • Comparable moldings are also in GB-A 1 448 849 and in US-A 4 187 407.
  • the object of the invention is based on this way optically appealing designed the junction To improve the adhesiveness of the adhesive at the connection point.
  • the invention is based on two exemplary embodiments with associated drawing ( Figures 1 and 2) described.
  • a connection point 1 according to the invention shown in FIG. 1 is created in that two deep-drawn sheet metal plates 2, 3 (also other materials in addition to sheet steel are conceivable, e.g. B. plastic) facing each other, angled, a trough between the webs 4, 5 forming a Weld 6 are interconnected.
  • the metal boards 2, 3 can can be galvanized or non-galvanized with respect to the weld 6 all conceivable welding processes (resistance spot welding, Electron beam welding, laser beam welding, etc.), but instead soldering, riveting, clinching etc. can also be used.
  • the sheet metal plates 2, 3 in the area of Junction 1 take different forms, as does the Transition from one to the other sheet metal plate 2, 3 may be different can.
  • a vehicle body for example, is constantly dynamic forces exposed.
  • Inelastic paint layers can reduce the vibrations and Do not resist thermal expansion in the long run, they would burst or tear. Too thin layers would provide insufficient protection against corrosion grant.
  • four or five layers are in a multi-stage process applied, namely a zinc phosphate layer, a cataphoretic primer, an elastic stone chip filler, a top coat and then a Clearcoat.
  • Adhesive seam 8 After the zinc phosphating and application and drying of the cataphoresis primer 7 is in a suitable manner on the trough filling this Adhesive seam 8 applied. It has been in practical trials a two-component polyurethane adhesive (Pliogrip) has proven its worth. Is the adhesive seam 8 at least tactile, so you can start adding more surface coatings, So using the example of a motor vehicle body an elastic Apply stone chip filler 9 and topcoat or clearcoat 10. It understands that the type and structure of the surface coatings covering the adhesive seam 8 may vary depending on what type of surface coated Sheet metal body in which the invention is used, is.
  • the adhesive seam 8 forms a leveling layer and also ensures that the strength of the connection beyond the quality of the weld 6 undergoes an optimization.
  • the adhesive seam 8 or the one used for it Material can harden (polymerize) at room temperature or in reasonable in the course of the stoving / drying process after surface coatings applied to it (stone chip filler 9, top or clear varnish 10). In the not yet hardened state it can also to be smoothed.
  • a major advantage is the adhesive seam 8 on the cataphoresis primer 7 can be seen in the fact that the adhesive material is thus a homogeneous Finds underground and that the primer in some ways also fulfills an adhesion promoter function.
