Definitions

  • the invention relates to a modular coating unit for painting plastic components, according to the preamble of claim 1. Furthermore, the invention relates to a method for painting plastic components.
  • a car series paint today consists of four layers, which are applied in several operations with different methods.
  • the degreased and cleaned body is provided by means of an electrochemical painting system into each cavity with a closed paint film.
  • This cathodic dip coating, KTL for short is the basis for comprehensive corrosion protection.
  • the cathodic, ie negatively charged body is driven through an aqueous, conductive dip paint, in which the positively charged paint particles adhere to the body and form a closed and uniform coating.
  • premixed mixed paints are used by paint suppliers, whereby the paints are mixed according to the specifications of the paint shop and the specification of the raw material manufacturer and the end customer at the manufacturer.
  • the vote in new series starts is carried out directly to FarbGermanvor inter and Lackieranlagenan petitionen and is therefore very complicated and costly, since only relatively small batch production be carried out and a large range of colors must be prepared and stored.
  • the invention pursues the idea of self-responsible mixing and packaging of different components in situ in the paint shop to a finished paint mixture and their use.
  • the object is achieved with a modular coating unit with at least one module as Lackiermodul for painting at least one workpiece made of plastic, and a mixer, wherein at least one module for the preparation of the paints for painting in the painting is present, the applied finish from a Base material is mixed from non-volatile components from a first container, in the module for the preparation of the coatings, solvent or water from a second container and concentrated color pigments and / or effect pigments from third containers are admixed.
  • the finished paint is based on base material, which can be made very low and transportable has a small volume and the other properties, for example, the final color are added only and be coordinated only on site by the painter himself. Also simplified by the late mixing of the solvent or water, the handling of the material and, especially when using water, the transport volume reduced overall.
  • the finished paint of base material from the first container (8) and solvent or water (L) from the second container (9) in a volume fraction of at least 80%.
  • a very cheap base material can be used by the paint manufacturer, which on different shades or properties of the finished coating can be the same and the final final vote is then achieved by an admixture of solvent or water and concentrated color pigments and / or effect pigments in the coating unit.
  • the mixer accesses the first container for base material, second container with solvent or water and the respective third container for concentrated color pigments and / or effect pigments (P).
  • the mixer communicates with the painting device, wherein it is also possible for the mixer to be integrated in the painting device.
  • the process according to the invention for the coating of plastic components with a modular coating unit provides that the finished finish used is mixed in situ in the coating unit from a base material, solvent or water and concentrated color pigments and / or effect pigments.
  • the finished paint is mixed in a mixer in the module for the preparation of the paints and transported as a finish to the coating unit.
  • the paint is mixed in a mixer in the coating unit. Even without an upstream mixer, it is advantageous if the finished paint is mixed in the spray of Lackierü by the components are fed simultaneously in the correct mixing ratio to at least one spray head.
  • the spray mist should be considered as a mixer.
  • the method has the further advantage that the paint is not premixed, but the components are applied successively in the correct application time.
  • the application of the different components can take place without real mixing.
  • a kind of pre-painting with the first robots or painting elements of the favorable base coat takes place and the final color tone adjustment takes place at the end by the application of the concentrate.
  • FIG. 1 a conventional painting plant is shown, as used for example for the painting of exterior components in the automotive industry. It is initially irrelevant whether metal components or plastic components are painted.
  • the paint shop has a Lackiermodul and consists mainly of a painting device 11, which can spray paint mist 10 with a robot or a permanently attached device on a workpiece 4.
  • the painting device 11 is a spray gun on a robot arm or a spray head of a Lackier Portugal.
  • a module is only an example. It can be used in parallel or successively a plurality of Lackiermodulen.
  • the paint sprayed by the spray gun or the painting bridge is covered by a container for paints 5.
  • These containers contain ready-to-use lacquers, which are delivered ready-mixed by the paint manufacturer.
  • the painting device can be connected to all containers for the paint 5 to be used. If, for example, bumpers are painted, the respective colors from the respective containers are used and exchanged for a respective group or individual workpieces.
  • the paints are finished mixed provided by the manufacturer. This results in large volumes of stockpiled finished paints, since each customer calls for his own red, his own black and so on.
  • FIG. 2 is a first variant of the solution according to the invention to see.
  • a mixer 8 is used in a module for the preparation of lacquers 2.
  • This mixer 8 is connected to a container 7 for a base material B and to a container 9 for solvent or water and also has connections to containers 6, 6 ', 6 ", 6"' with concentrated color pigments and / or effect pigments ,
  • a paint consists of volatile solvents and non-volatile components.
  • the non-volatile components are binders, pigments, oils, resins, fillers and additives.
  • the binder provides a good, uniform suspension with pigments and solvent in the paint, is responsible for an optimal drying process and the gloss after drying.
  • the essential basis of a paint is the binder and solvent. Pigments are not necessary components of a paint.
  • the base material in the first container 7 consists mainly of the non-volatile constituents without concentrated color pigments and / or effect pigments, wherein a small percentage of solvent is useful for the further processing of the base material.
  • the container 3 is also used as a water connection consider. In this case, the handling of the base material is even more efficient, since no solvent needs to be transported.
  • the second container 6 ... contain colors with a high color pigment density or metal particles, as they are needed for metallic finishes.
  • the mixer 8 the components, the base material, solvent or water and the concentrated color pigments and / or effect pigments are mixed to obtain the desired paint result as a finished finish.
  • a mixing ratio of approximately 80% base material + solvent / water with 20% concentrated color pigments and / or effect pigments is advantageous.
  • base material + solvent that is less expensive than the color pigments.
  • Optimal is a range of 10-20% base material, 60-70% solvent / water, 10-30% concentrated color and / or metal pigments.
  • the pre-mixed in the mixer 8 finished paint is supplied to the painting device 11 and applied to the workpiece 4.
  • the three components without a separate mixer are mixed directly in the spray 10, which is possible by suitable design of the nozzles.
  • the spray itself acts as a mixer.
  • FIG. 5 shows the distribution V of the color pigments over the thickness d of the lacquer layer.
  • Another embodiment does not use a uniform mixture of the three components in the lacquer layer but builds up the lacquer layer from a mixture of base material + solvent / water with at least one thin concentrated color and / or metal pigment layer.
  • This color layer can be on the surface of the lacquer layer or is integrated in the layers of the base material + solvent / water.
  • the base material + solvent / water is applied and then applied a thin layer of the concentrated color and optionally again a series of basecoat and paint.
  • FIG. 4 a process schematic is shown.
  • a layer of base material + solvent / water is provided for the painting device.
  • the component of concentrated color and / or metal pigment layer is mixed in a further step 42 to the base material + solvent / water and in step 43, the mixture is applied. For a uniformly colored coating is possible.
  • the first step is to apply a layer of base material + solvent / water followed by application of a thin layer of concentrated color and / or metal pigments, which may be repeated as desired.
  • the result is either a finished paint mixture that is homogeneously maintained throughout the paint layer, or extends only to a thin layer S.
  • color residues consisting of color pigments to a currently used color mixture in the finished paint possible.
  • black color pigments of one customer to the black color pigments of another customer, supplied by another paint manufacturer at least partially immiscible.
  • This material can be recycled, which would otherwise be disposed of.
