Definitions

  • the invention relates to a plastic molded body with a polymer phase formed from a curable reaction mass and embedded therein plastic granules, which are composed of at least one resin material, first fillers and first color pigments, according to the preamble of claim 1. Furthermore, the invention relates to plastic granules for plastic moldings from washing - And sanitary area, according to the preamble of claim 15.
  • Plastic moldings are known from DE 19920 719 A1, which have a polymer phase formed from a curable reaction mass and particulate filling materials embedded therein.
  • the filling materials comprise a resin agent filled with an inorganic filler and have at least 10% by volume of particles which have two or more differently colored, superficially visible polymer layers.
  • two differently colored, filler-containing casting resins are first produced from the components required in each case, which are poured from thin nozzles into a type of baking tray with an oscillating movement. Care is taken to ensure that as many phase boundaries as possible arise between these two cast resin strands. The viscosity of the two casting resins is designed so that mixing is essentially avoided. After such a baking tray is filled, the mass is hardened in a press. After grinding the cured material creates a granulate, which shows a coating of transparent and colored material on its surface, for example. Accordingly, plastic granules of this type are made up of particles of several layers which extend through the entire particles. In this way, a multi-colored effect of the individual particles is achieved.
  • Such plastic granules are then embedded in a generally fully colored plastic matrix that represents the polymer phase. This creates the optical effect of embedded, colored particles with precisely outlined color edges within the fully colored plastic matrix. However, such a sharp demarcation of color contours is not always desirable.
  • plastic moldings designed in this way have an unsatisfactory resistance to hydromechanical stress. Frequently, micro-cracks occur between the plastic granules and the surrounding binder matrix or plastic matrix in the relevant stress tests, which have a disadvantageous effect on the color effects and the overall optical impression of the molded plastic part.
  • the object of the present invention is to provide a molded plastic part which has a high resistance to hydromechanical loads and an optically advantageous color effect. Furthermore, it is an object of the present invention to provide plastic granules for such molded plastic articles with high resistance and advantageous color effects.
  • the main idea of the invention is to provide the plastic granules with at least one surface layer of a polymer covering their entire surface in the case of a plastic molded body with a polymer phase formed from a curable reaction mass and embedded therein plastic granules made of at least one resin material, first fillers and first color pigments.
  • the surface Layer 0.1 - 50% by mass, based on the plastic granules, on the polymer.
  • the surface layer can consist of a second filler and second color pigments.
  • Plastic granule grains surface-coated in this way advantageously show the optical effect of a corona appearance at their grain boundaries with the binder matrix surrounding them. Such a corona appearance clearly stands out from the mostly likewise colored binder matrix.
  • the surface layer has layer thicknesses of 1 to 100 ⁇ m with a grain size of the plastic granules with a coarse structure of 0.1 to 8 mm, preferably 0.5 to 8 mm.
  • Such a thin, polymer-bound, colored or colorless surface layer awakens a 3-D effect to the viewer of a molded plastic part made therefrom, which can be, for example, a kitchen sink or a sanitary part or the like, and thus has a certain depth effect when viewing such molded articles.
  • the thin colored polymer surface layer can be formed in different shades, so that a corona coloring can be obtained both when using a similar or identical color or a contrasting color to a color of the binder matrix.
  • Plastic granules coated in this way have a significantly improved integration into the binder matrix of the molded plastic body, which can be demonstrated by hydromechanical load tests, for example according to the ANSI Z 124.3 (6.3) standard, to determine the thermal shock resistance. Results in this regard show a significant reduction in unwanted microcracks between the plastic granules and the binder matrix surrounding them. As a result, the resulting color deviations are smaller than previously known.
  • an intermediate layer can preferably be formed between the surface of the plastic granulate layer and the surface layer with third color pigments and / or third fillers. This would be formed in a step preceding the formation of the surface layer.
  • the intermediate layer preferably has 0.1-50% by mass, based on the plastic granules, of color pigments.
  • the first, second and / or third fillers and the first, second and / or third color pigments are organic or inorganic in nature, aluminum trihydroxide being preferably used as the filler.
  • All color pigments can be replaced individually or as a whole by color pastes.
  • At least one acrylic, epoxy and / or polyurethane resin is preferably used as the polymer and resin material and for the polymer phase.
  • Plastic granules for plastic moldings from the washing-up and sanitary area with at least one resin material, first fillers and first color pigments advantageously each have the surface layer made of the polymer covering their entire surface, the use of plastic granules coated in this way also being conceivable for other areas, such as for example the floor area is.

  • inorganic or organic color pigments mixed intensively and then deaerated. Thereafter, this is cured as a mixture. lying mass instead of in the form of plates, whereby the curing can take place at room temperature or higher temperature.
  • the plates are crushed and sieved using a sieving process in order to obtain plastic granules with a desired grain size. These plastic granules are completely dyed through and usually contain pigment and filler.
  • the granules are mixed in a container to form an intermediate layer with a mixture of further color pigments and optionally further fillers, wherein the organic or inorganic color pigments can also be replaced by color pastes.
  • the proportion of the color pigments can be 1-50% by mass, based on the amount of plastic granules used.

  • the amount of binder here is 1-50% by mass, preferably 1-12% by mass, and more preferably 3-8% by mass, based on the amount of plastic granules used.
  • Suitable types of binders are mixtures based on acrylic, epoxy or polyurethane resins.
  • these surface layers are cured with the addition of catalysts at a temperature between 1 ° C. and 200 ° C.
  • the coatings of the plastic granules can be carried out in a one-step step in such a way that a mixture of a polymer matrix with color pigments and fillers is used for the surface layer.

  • plastic moldings can be wash basins, shower basins, sinks and the like. As a rule, these products are reworked in the form of a grinding or polishing process in order to increase the surface quality.
