Definitions
- the invention relates to a process for spray painting with aqueous paints, in which several aqueous paints with different shades are processed in one and the same painting system and the paint (overspray) which did not appear on the substrate to be painted with water from the exhaust air of the painting system is washed out of and from the parts of the painting system which come into contact with overspray, and the water enriched with overspray is concentrated and fed back to the painting process as recovered aqueous paint, optionally after admixing newly supplied paint (fresh paint).
- the paint (overspray) that does not appear on the substrate to be painted is washed out with water from the exhaust air of the painting system - and washed off from the parts of the painting system that come into contact with overspray.
- the overspray is precipitated from the water enriched with overspray. In this way, paint sludge is created, which is only available in limited quantities
- Scope can be worked up to other products and in many cases must be disposed of as waste.
- the task on which the present invention is based consists in the provision of a method for spray painting of the type described above which does not have the disadvantages of the prior art or only has them to a reduced extent.
- the type and quantity of the substrates to be coated in the coating system are selected such that some of the substrates to be coated in the coating system are mixed with a mixture of the aqueous paints to be processed in the coating system with different shades of color (“mixed coating”) can be painted and
- aqueous lacquer 10 to 90, preferably 30 to 70, particularly preferably 40 to 60% by weight
- the concentration of the water enriched with overspray can be carried out in various ways, for example by mechanical separation using, for example, centrifuges or decanters, using membrane processes, in particular using ultrafiltration, using thermal processes (for example vacuum evaporation). or using electrophoretic deposition or by a combination of one or more of the methods listed.
- the concentration of the water enriched with overspray is preferably carried out with the aid of ultrafiltration. Plants suitable for concentrating water enriched with Over ⁇ spray are commercially available, for example from Eisenman, Holzgerlingen, Germany.
- Automobile bodies are usually painted by applying an electrocoat layer in a first step, which is then overcoated with a filler layer after baking.
- the filler layer is then baked or, in the not yet baked state, overpainted with a one- or multi-layer, in particular two-layer top coat.
- the top coat is baked, and in cases in which the top coat has been applied to the filler layer which has not yet been baked, the filler layer is also baked.
- the main tasks of the filler layer are to compensate for unevenness and defects in the electrocoating layer and to improve the stone chip resistance of the overall coating.
- the non-opaque top coat has the desired color.
- Filler with color tones that are matched to the color of the top coat are often used so that the damaged areas of the paint are not as noticeable in the case of stone chip damage as is the case with filler layers that differ very strongly in color from the color of the top coat. Due to the changing colors of the topcoats, the color of the filler used must often vary.
- the type and number of automobile bodies to be painted with the different colored top coats is regulated by market demand.
- the first step is to clarify which different colors the fillers to be used must have in any case. The colors of the fillers depend - as explained above - on the colors of the desired top coats.
- Color tones can be used as a filler for the largest possible amount of the topcoats to be painted.
- “Mixing varnish” are varied until the amount of topcoats to be processed, for which the “mixing filler” or “mixing varnish” can be used due to its color, is as large as possible and at the same time the ratio in which the filler with different colors in the " Mixing filler "or” mixing varnish "are included as close as possible to the quantitative ratio in which the fillers with different colors are used.
- the recovered aqueous varnish which may contain admixed fresh varnish, has essentially the same shade as the "mixed varnish” described above (in the example " "Essentially” means that in practice more or less slight color deviations are tolerable, but it is preferred that the color of the recovered aqueous varnish
- Lacquer matches the color of the "mixed lacquer”.
- the color tone of the recovered aqueous lacquer can be influenced by selecting the ratio in which the aqueous lacquers are processed with different color tones and / or by selecting the color tone of the fresh lacquer which may be mixed in such that it essentially corresponds to the color tone of the under (a) the mixed paint described.
- the selection of the ratio in which the aqueous paints are processed with different shades are done via a corresponding selection of the substrates to be painted in the painting system. The closer the quantitative ratio in which the aqueous lacquers are processed with different colors comes to the quantitative ratio in which the aqueous lacquers with different colors are contained in the mixed lacquer described under (a), the less need be corrected by adding appropriately tinted fresh lacquers become.
- the method according to the invention is preferably used for painting automobile bodies with aqueous fillers which have different colors. However, it can also be applied to all spray painting processes with aqueous paints, in which several aqueous paints with different colors are processed in one and the same painting installation and the paint (overspray) which did not appear on the substrate to be painted with water from the exhaust air the painting system is washed out and washed off from the parts of the painting system that come into contact with overspray, and the water enriched with overspray is concentrated and returned to the painting process as recovered aqueous paint, optionally after admixing newly supplied paint (fresh paint).
