Definitions

  • the invention relates to a method for producing a Multi-layer paint on hinged flaps, doors or the like accessible inner wall surfaces and on unhindered accessible outer wall surfaces of an object, in particular for Painting a vehicle body with at least one base layer as well as with at least one colored cover layer. Precautions are required for this procedure Avoid pollution of the object during the Painting hit.
  • Contamination of objects to be painted during the run from the blank to the completion of a multi-stage painting process still the main cause of costly paint rework.
  • the result is the subsequent paint application dirt and fiber inclusions or Wetting disorders, particularly with high-quality and high-priced products such as motor vehicles too unacceptable Results in painting.
  • Common methods of doing this are the housing of conveyor lines through partially ventilated tunnels as well as the use of clean room technology.
  • top layers To be able to meet the requirements for elasticity and protection applied a number of layers in a multi-stage process. These are a zinc phosphate layer, a cataphoresis primer and an elastic stone chip filler as base layers and the color of the Top coat determining vehicle body (plain, metallic or effect paint), which is generally followed by a clear coat, both here generally as top layers designated.
  • An elastic primer is then applied to protect against stone chips with the so-called stone chip filler. This will also follow Then apply baked in a drying oven (at approx. 150 ° C). This makes the paint layers more resistant to mechanical influences and chipping of the top coat largely avoided.
  • a top coat in the color desired by the customer follows. During the painting process, the paint particles are removed by an electrostatic Field of high voltage spray heads to the grounded Body transported. In addition, all bodies are given a clear coat.
  • the finished painted bodies are then subjected to a wax flood process subjected.
  • the cavities become hot at approx. 120 ° Preserved wax. With this further increase in corrosion protection the painting process is finished.
  • the invention is therefore based on the object, the generic To improve painting processes so that just the the latter pollution problems can be prevented.
  • the main idea of the invention is therefore to be seen in the fact that when it is still open Flaps, doors or the like (due to the previous order a last base layer) the inner wall surfaces with the first cover layer be provided so that (preferably after drying this the cover layer representing the final treatment) the flaps, doors or the like can be closed as far as possible.
  • a coating with clear lacquer for optical and anti-corrosion reasons the inner wall surfaces are not required.
  • the flaps and doors then no longer have to be opened.
  • the first top coat is applied to the last applied base layer on the inner wall surface "wet in wet".
  • the Paint technology "wet in wet” is known per se in the prior art (DE 34 35 937 C2, DE 38 06 257 C2), insofar as, for example, a metallic basecoat with clear lacquer and clear lacquer with decorative lacquer as quickly as possible can be applied to the vehicle body one after the other. in the the second-mentioned document finds this technique in two-color painting Application. It is also known (DE 27 40 246 A1) a second Apply primer coat on a first "wet on wet” to after a Intermediate drying and application of a first layer of paint on it apply another layer of paint "wet on wet”.
  • Claim 5 indicates to the first layer of paint "wet on wet” on the apply previously applied stone chip filler.
  • FIG. 1b The processes shown in FIG. 1b apply when using solvents Paints. However, if water-soluble paints are used, it is recommended that between the top coat application - outside - and the clear coat application to provide an intermediate drying stage. The basis of the invention however, the underlying idea remains unaffected. Your use at Water-based paints should therefore be viewed in the same way.
  • FIG. 2 shows the inner wall regions of a vehicle body 1, who preferably receive a top coat already in the filler cabin should. These are the engine compartment 2, the inside of the hood 3 and the trunk 4, trunk lid inside 5, door edge surfaces 6 and door frame 7.
  • a top coat of the passenger compartment 9 is not provided.
  • the outer body surface 8 at the same time (in one work step) with the inner wall surfaces 2 - 7 with the first colored To provide top layer.
