Definitions
- the present invention relates to a new color and or effect paint with a combination effect layer.
- Coloring and / or effect-giving paintwork of motor vehicle bodies, in particular car bodies, today preferably consist of several layers of paint which are applied one above the other and have different properties.
- an electrically deposited electrodeposition coating as a primer, a filler coating or stone chip protection primer, a base coat and a clear coat are applied to a substrate in succession.
- the ETL serves in particular to protect the sheet against corrosion. It is often referred to by experts as a primer.
- the filler coating is used to cover unevenness in the surface and, due to its elasticity, ensures resistance to stone chips. If necessary, the filler paint can also serve to increase the hiding power and deepen the color of the paint.
- the base coat contributes the colors and / or the optical effects.
- the clear coat serves to enhance the optical effects and to protect the paint from mechanical and chemical damage. Basecoat and clearcoat are often collectively referred to as topcoat.
- Paints are often carried out in four separate steps, between which each has to be flashed off and possibly also baked, which at a high time and workload as well as increased energy and plant costs.
- Another disadvantage is the environmental impact when using solvent-based paints.
- Corresponding lacquers such as ETL, aqueous fillers, water-based lacquers or aqueous clear lacquers, powder lacquers or powder lurry clear lacquers are available. When they are used together in the course of producing a coloring and / or effect coating, however, their properties must be coordinated very finely with one another in order, for example, to prevent the uncured layers from collapsing when using wet-on-wet processes and / or to prevent the formation of cracks, the formation of stoves and / or the delamination of layers. In addition, a comparatively large amount of organic cosolvents must still be used in particular in the case of waterborne basecoats in order to stably disperse the pigments and to ensure that the applied layers run smoothly.
- Japanese patent application JP 53 109 540 A1 shows a coating with a 10 to 45 ⁇ m thick base coat, produced from a pigmented powder slurry that is not specified in more detail, and a 30 to 70 ⁇ m thick clear coat. It is not specified whether the basecoat also acts as a filler or stone chip protection primer.
- a powder slurry containing metal effect pigments based on amine-neutralized acrylate copolymers and melamine resins or of polyesters and epoxy resins is known from German published patent application DE 27 10 421 A1.
- the production of the pigmented powder slurries requires the neutralization of the water-soluble amine-neutralized starting products with hydrochloric acid. However, this can cause lasting damage to the metallic effect pigments.
- the well-known powder slurry provides smooth, shiny, metallic coatings. It is not said whether these can also take on the function of filler coatings in coatings.
- Japanese patent application JP 02 014 776 A 2 discloses a multi-layer coating comprising a base coat and clear coat, the base coat of which is produced from a pigmented powder slurry based on hydroxyl-containing acrylate copolymers and blocked polyisocyanates.
- the basecoat can also act as a filler or stone chip protection primer.
- the object of the present invention is to provide a new coloring and / or effect coating with a reduced number of layers of paint, which no longer has the disadvantages of the prior art, but which is possible in fewer process steps than before and without the use of Can produce cosolvents, with the good application properties of the known coatings in all their functions in full, if not to be exceeded.
- the new coloring and / or effect coating for a primed or unprimed substrate which contains a combination effect layer, the combination effect layer being producible from a pigmented powder slurry.
- coating according to the invention the new coloring and / or effect coating for a primed or unprimed substrate is referred to as "coating according to the invention".
- pigmented powder slurries the manufacture of those to be used according to the invention
- Combination effect layers allow the function of both filler and stone chip protection primers as well as basecoats. This is all the more surprising since, on the one hand, the pigmented powder slurries are always proposed for the production of lacquer layers with essentially only one function and, on the other hand, the customary and known filler coatings and basecoats are made from coating materials, which are very different in terms of material and very specific to them are adapted to the respective purpose.
- the combination effect layer to be used according to the invention is essential for the coating according to the invention.
- this is to be understood as a coating which fulfills at least two functions in a coloring and / or effect coating. Functions of this type are in particular protection against corrosion, the imparting of adhesion, the absorption of mechanical energy and the coloring and / or effect.
- the combination effect layer serves above all for the absorption of mechanical energy and for coloring and / or effecting at the same time; it therefore fulfills the functions of a filler paint or stone chip protection primer and a base coat.
- the combination effect layer preferably also has a corrosion protection effect and / or an adhesion-promoting effect.
- the thickness of the combination effect layer is preferably constant within a given coating according to the invention. In some cases, however, it may be advisable to make the thickness thinner in the regions of the substrate which are less exposed to mechanical action and / or are less or not visible at all, in order to save material.
- the thickness of the combination effect layer can be very wide from the coating according to the invention to the coating according to the invention vary.
- the optimal thickness for each individual case depends in particular on the hiding power of the pigments used (cf. Römpp Lexikon Lacke und Druckmaschine, Georg Thieme Verlag, Stuttgart, New York, 1998, page 124, "Hiding power”), the ability to use mechanical energy to absorb or dissipate, the ability to compensate for the unevenness of the substrate surface, and / or the other constituents of the powder slurry used in each case
- the person skilled in the art can therefore determine the optimum thickness based on his general specialist knowledge, if necessary with the aid of simple preliminary tests
- the thickness of the combination effect layer is 10 to 100, preferably 15 to 90, particularly preferably 20 to 80, very particularly preferably 25 to 70 and in particular 30 to 60 ⁇ m, in each case based on the layer.
- the combination effect layer can be produced from a pigmented powder slurry.
- the pigmented powder slurry to be used according to the invention contains at least one finely divided dimensionally stable component, i.e. a powder coating, as a disperse phase and an aqueous medium as a continuous phase.
- the finely divided component or powder coating can be solid and / or highly viscous.
- “highly viscous” means that the particles behave essentially like solid particles under the customary and known conditions for producing, storing and using powder slurries.
- the powder coating material is preferably solid.
- the individual particles of the finely divided component are also dimensionally stable.
- dimensionally stable means that the particles are among the usual and known Conditions of storage and use of pigmented powder slurries, if at all, only agglomerate slightly and / or disintegrate into smaller particles, but also essentially retain their original shape under the influence of shear forces.
- the solids content of the pigmented powder slurry is preferably 10 to 80, preferably 15 to 75, particularly preferably 20 to 70, very particularly preferably 25 to 70 and in particular 30 to 65% by weight, in each case based on the pigmented powder slurry.

- the mean particle size is understood to mean the 50% median value determined by the laser diffraction method, i.e. 50% of the particles have a particle diameter ⁇ the median value and 50% of the particles have a particle diameter> the median value.
- Pigmented powder slurries with medium particle sizes of this type have better application behavior and, with the applied film thicknesses of> 30 ⁇ m, as are currently practiced in the automotive industry for the first coating of automobiles, surprisingly show a significantly lower tendency towards stoves and "mud cracking" than conventional combinations of filler, basecoat and clearcoat.
- the upper limit of the particle size is when the size of the particles means that they can no longer run completely when they are burned in and thus the film run is negatively influenced.
- the upper limit of 40 ⁇ m is considered to be sensible, since clogging of the rinsing channels of the highly sensitive application equipment can be expected from this particle size.
- the pigmented powder slurry is preferably free of organic solvents (cosolvents). In the context of the present invention, this means that it has a residual volatile solvent content of ⁇ 1% by weight, preferably ⁇ 0.5% by weight and particularly preferably ⁇ 0.2% by weight. According to the invention, it is of particular advantage if the residual content is below the gas chromatographic detection limit.

- the proportion present in the powder coating particles can be the main amount, ie more than 50% of the pigments used. However, there may also be less than 50% in the powder coating particles. With regard to the particle sizes, what has been said above also applies here analogously. Which variant of the pigmented powder slurry to be used according to the invention is preferred depends in particular on the nature of the pigments and / or on the process by which the pigmented powder slurry used in each case is produced. In most cases, the first preferred embodiment offers particular advantages, which is why it is particularly preferred according to the invention.

- the proportion of pigments, including the fillers, in the pigmented powder slurries to be used according to the invention can vary very widely and depends on the requirements of the individual case, in particular on the optical effect to be set and / or the opacity of the pigments used in each case.
- the pigment content is preferably 0.5 to 80, preferably 0.8 to 75, particularly preferably 1.0 to 70, very particularly preferably 1.2 to 65 and in particular 1.3 to 60% by weight, in each case based on the solids content of the pigmented powder slurry.
