Definitions

  • the invention relates to a method for manufacturing and repair of multi-layer effect paints.
  • Pneumatic application methods stand out disadvantageous in that a relatively large Part of the sprayed amount of paint does not cover the substrate reached, which has the consequence that the circulating air in the Spray booth must have high speeds, thus the relatively large amounts of overspray deposited and can be disposed of.
  • the basecoat film is preferably in only one spray cycle, exclusively made by electrostatic spraying.
  • electrostatic spraying the amount is of the sprayed paint material that the substrate achieved considerably larger than with pneumatic application processes.
  • the speed the circulating air in the spray booth is reduced can and that smaller amounts of paint overspray have to be processed and disposed of.
  • all of the platelet-shaped pigments containing platelet-shaped pigments suitable for the serial painting of automobile bodies can be used, provided they have a solids content of 18% by weight and a temperature of 23 ° C. at a shear rate of 1,000 s -1 after a shear time of 6 s an apparent viscosity of 40 to 200, preferably 60 to 150 mPa s, after a shear time of 300 s at a shear rate of 1000 s -1 an apparent viscosity of 40 to 200, preferably 60 to 150 mPa s, at a shear rate of 5 s -1 after a shear time of 10 s an apparent viscosity of 100 to 2000, preferably 200 to 800 mPa s and after a shear time of 300 s at a shear rate of 5 s -1 an apparent viscosity of 100 to 2000, preferably 500 to 1500 mPa s, the measurements carried out at the shear rate of 5 sec
  • rheology aids such as, for example, crosslinked polymer microparticles (cf. for example EP-A-38127), finely divided silica, anionic polyacrylate resins, layered silicates, etc.
  • the person skilled in the art can in principle apply any basecoat suitable for series coating to a viscosity behavior, that meet the above conditions.
  • the basecoats used in stage (1) of the process according to the invention can be either aqueous or non-aqueous.
  • Aqueous basecoats are described, for example, in EP-A-38127 and non-aqueous basecoats are described, for example, in US-A-4,220,679.
  • the method according to the invention is particularly suitable good for making and repairing multilayer Effect coatings with darker shades (e.g. Diamond Black) and for the production and repair of multi-layer effect paints with lighter ones Shades (e.g. silver).
  • darker shades e.g. Diamond Black
  • lighter ones Shades e.g. silver
  • Basecoat layer exclusively by electrostatic Syringes is made.
  • electrostatic Spraying is the amount of paint material sprayed, which reaches the substrate, much larger than with pneumatic application processes. That has as a result that the speed of the circulating air in the Spray booth can be reduced and that lower Amounts of paint overspray worked up and disposed of Need to become. It can also be used to manufacture multi-layer effect painting necessary painting system be significantly reduced if the basecoat layer exclusively by electrostatic Syringes is made.
  • the application of basecoats containing platelet-like pigments electrostatic spraying is good for the person skilled in the art known and therefore does not need any further details here to be explained
  • Spray application process in which the paint drops of the spray jet meet the above-mentioned conditions can, for example, with the help of HVLP (high volume, low pressure) fuel pistols that are commercially available are available.
  • the diameter, the speed and thus the impulse of the Drops of paint in the spray jet essentially depend on the paint flow rate, the amount of atomizing air or Atomizing air pressure, paint viscosity and Nozzle geometry.
  • a reduction in paint flow rate has, for example, a reduction in the paint drop diameter and an increase in speed the paint drops result.
  • An increase in atomizing air pressure also leads to a reduction the paint drop diameter and to an increase the speed of the paint drops.
  • phase Doppler anemometry method is used by W.D. Bachalo and M.J. Houser in OPTICAL ENGINEERING / September / October 1984 / Vol.23 No.5 on pages 583 to 590.
  • the basecoat film thus obtained is after an intermediate drying (10 min, 80 ° C) with a commercially available a polyacrylate resin as a binder and a melamine resin as a clearcoat containing crosslinking agents overcoated (dry film thickness of the clear coat: 50 ⁇ m) and then basecoat and clearcoat 20 Baked at 140 ° C for minutes.
  • half of the painted test board is taped with an adhesive strip and the remaining half is sanded with sandpaper (800). Then the basecoat used for the initial painting is applied with an HVLP spray gun (De Vilbiss GFHV-511, manufacturer: De Vilbiss; cap: air cap No. 152, nozzle EY 7; atomization pressure: 0.4 bar, measured at air cap; spraying distance: 30 cm to Substrate) in a first application (first cloister) sprayed in a dry layer thickness of 6-8 ⁇ m.
  • HVLP spray gun De Vilbiss GFHV-511, manufacturer: De Vilbiss; cap: air cap No. 152, nozzle EY 7; atomization pressure: 0.4 bar, measured at air cap; spraying distance: 30 cm to Substrate
  • the spray jet produced is characterized in that 25% of the drops of paint passing a measuring point located in the center of the spray jet and 300 mm from the nozzle have a diameter which is below 20 ⁇ m and 15% of the drops of paint which pass this measuring point happen, have a diameter that is over 60 microns. In addition, 33% of the drops of paint passing the measuring point have a speed which is below 6 m / s, and 17% of the drops of paint which pass the measuring point have a speed of more than 10 m / s.
  • the impulse of the paint drops that pass the measuring point is 6.8 ⁇ 10 -5 g cm s -1 .
  • the diameter and the speed of the paint drops were determined using the phase Doppler anemometry method.
  • the basecoat film thus obtained is after an intermediate drying (10 min, 80 ° C) with a commercially available a polyacrylate resin as a binder and a Clear varnish containing polyisocyanate as crosslinking agent overcoated (dry film thickness of the clear coat: 45 ⁇ m) and then basecoat and Clear coat baked at 140 ° C for 30 min.
