Definitions

  • the invention relates to a method for producing pigment-containing products according to the preamble of patent claim 1.
  • Such methods are, for example, for the manufacture of building materials in the form of paints, primers, plasters u. Like. Used.
  • the color of the building materials is determined by the pigment composition and pigment concentration in the base material.
  • both mineral products in which the Base material is available as dry bagged goods, as well as pasty products in which the finished products are available as bucket goods are produced.
  • Mineral products in which the pulverulent pigments are mixed at the factory with pulverulent carrier materials are mixed and processed at the place of processing with mixing water. In this case, the pulverulent pigments are blended with the carrier material at the factory and filled into sacks.
  • the base material is colored according to given colors with suitable dosing using suitable pigment concentrates.
  • suitable pigment concentrates are metered into a prefabricated base container by means of a volumetric or gravimetric metering method on defined amounts of base material.
  • the pigment-containing products are requested by the processor in the required quantity from the manufacturer, manufactured and delivered according to the color specifications of the processor.
  • the required amount of pigment-containing products is not exactly known, because the substrate and processing method significantly influence the consumption quantities and an exact oversize of the surfaces to be provided with the pigment-containing products is often not available.
  • the processor orders too little material from the manufacturer, it may be necessary to reorder the material, which has to be remixed according to the manufacturer's color requirements. This is associated with a high loss of time and thereby incurred costs.
  • the processor requests too much pigment-containing products from the manufacturer, the product made according to specific customer color requirements can not be used at other processing locations and must then be disposed of. This is also associated with high costs.
  • the invention has for its object to provide a method for producing pigment-containing products, with which any color tones can be produced quickly, reliably and inexpensively. According to the invention this object is achieved by the specified in the characterizing part of claim 1 development of the known methods.
  • the production of a pigment concentrate with the desired pigment mixture takes place in the metering container itself, so that it is not necessary to resort to bottoms or base colors filled into individual metering containers.
  • the pigment mixture thus produced in the dosing can be fed to the base material at the processing site and mixed with conventional mixing devices customary in the field, such as mixing mixers in the form of rotary-type drilling machines.
  • the invention is based on the finding that it is in the known processes for the production of mineral products to Agglomerat embarrassed of pigments or clumping of the pigments can occur, which influence the coloring. When processing on the facade, streaks or streaks may form.
  • 5.0 ml of yellow pigments may be mixed with 0.2 ml of red pigments. Even if only a small part of the red pigment does not get into the base material, the color is yellowish, but not apricot-colored.
  • This deficiency is remedied in the method according to the invention in that the pigment-containing base materials are already mixed together in the dosing, so that no change in the color mixture takes place when a small remainder of the mixed in the dosing tank raw materials is not expelled.
  • the pigment-containing base materials may already be in the form of pasty products. It may be dissolved in a carrier solution pigments.
  • a pigment-free base material is first filled into the metering container and only then is the pigment-containing base material added. This can prevent the pigments from settling in the bottom region of the dosing container and from the following mixing process in full take part. Thus, a particularly reliable production of predetermined tints is achieved.
  • the settling of the pigments at the bottom of the dosing is particularly reliably prevented because the pigment-free base material both embodiments of inventive method has a greater density than the pigment-containing base materials, so that when charging the dosing a heterogeneous mixture is formed therein.
  • the pigment-free base may be a binderless and pigment-free "paint" comprising water, thickening agents, preservatives, wetting agents, defoaming agents and / or inorganic fillers.
  • the density of the pigment-free base material is preferably more than 1.5 g / cm 3 , esp. More than 2.0 g / cm 3 , more preferably about 2.2 g / cm 3 , while the viscosity may be 2000 mPa.s.
  • the pigment-containing base materials advantageously have a density of 1.05 g / cm 3 to about 2.2 g / cm 3 , wherein these base materials may have a viscosity of 2000 mPa.s.
  • the pigment-containing base materials may comprise water, wetting agents, preservatives, thickeners and / or defoaming agents.
  • the dosing is filled after filling the pigment-containing raw materials with a pigment-free base material of lower density.
  • the metering container may have a filling volume of 0.5 to 1100 ml or more, wherein to allow complete mixing of the raw materials filling up to max. 90% of the filling volume, preferably up to max. 80% of the filling volume of the dosing tank takes place.
  • the metering container has a syringe cylinder having a piston opening and an outlet opening, wherein the piston opening is closed after filling the basic materials and before the mixing process with the syringe plunger.
  • the closing of the syringe plunger, while avoiding the pressing out of the filled into the syringe barrel raw materials can be facilitated if the insertion of the syringe plunger through the piston opening facilitating vent opening is provided in a wall of the syringe barrel preferably made of transparent material, after closing the piston opening with the syringe plunger is closed.
  • the vent is suitably provided at about 100% of the filling amount of the syringe barrel.
  • the mixing of the raw materials taking place when carrying out the process according to the invention can be carried out, for example, with the aid of a biaxial mixer.
  • the dosing container charged with the basic materials are clamped with suitable devices in a plastic box, wherein a realized in the form of a syringe dosing can be firmly fixed in the box, while a realized in the form of a tubular bag dosing is placed in a pre-filled with chips plastic container, the Plastic container filled with chips, sealed and then mixed using the biaxial mixer.
  • the loading of the dosing with the pigment-free and / or pigment-containing raw materials can be done via volumetric and / or gravimetric dosing.
  • a small hole in the wall of the syringe barrel is formed at a predetermined location, such as at 90% of the filling volume to after loading the syringe barrel with the pigment-containing fillers or pigment pastes and optionally another carrier material to sit the syringe plunger for expressing directly.
  • the vent hole can be closed with a label.
  • a preferably non-contact mixing takes place in a suitable mixing device, such as a biaxial mixer. It may be a standard mixer, for which the above-described special jigs can be built. Care must be taken to the stability of the jigs.
  • a foam core surrounds the entire Container and the entire core is clamped in the biaxial mixer and mixed for about 3 minutes.
  • the invention is not limited to the above-outlined invention example.
  • three or more pigment-containing raw materials may be mixed together in the dosing tank. It is also possible to dispense with the metered addition of a pigment-free second base material after charging with the pigment-containing base materials. Density and viscosity of the raw materials may differ from the values given above.
  • the invention can also be used in the context of the production of mineral pigment-containing products.
