Definitions

  • the invention relates to a method for preparing colloidal paint sludge solutions or paint overspray from automotive painting according to the preamble of claim 1.
  • Such a method is already known from DE-PS 35 16 965. This method is advantageous in that it disposes of a phosphate sludge obtained in the metal treatment, so that karin does not have to be purchased from a commercially available coagulant.
  • the object of the present invention is to remedy this and to provide a method which not only works in an environmentally friendly manner but also economically.
  • the metal oxide dust to be disposed of regardless of the type and weight distribution of its metal oxides, is no longer shipped to hazardous waste landfills, but instead is used for a new purpose as coagulation and detackifying agent for colloidal paint sludge solutions or paint overspray from automotive painting .
  • this requires the Addition of a small amount of 2O5 and surfactant, while the flocculants required according to DE-P 35 16 965 can surprisingly be dispensed with.
  • the pH can be adjusted within a fairly wide range depending on the CO 2 content of the water. A pH of 8.5 is only advantageously set.
  • paint is applied to the body, paint mist wet separators being provided for paint spray booths in which a so-called “overspray” is obtained, which is washed off a wall with water and solvent.
  • the resulting colloidal system is mixed with approximately the same amount of metal oxide dust, to which 0.2 part by weight of ethylene propylene oxide and 2 parts by weight of P2O5 are added in a small amount.
  • Coagulation and detackification convert the resin particles or coating materials into larger agglomerates that can be easily removed.
