Definitions

  • the present invention relates to a glass composition containing crystalline phases and glass flakes consisting thereof.
  • Glass slides can be used as the base substrate for effect pigments.
  • the glass slides can continue to be used in paints, coatings, printing inks, plastics and in cosmetic formulations. 10
  • the glass flakes described therein have the disadvantage that they preferably contain high levels of toxic heavy metals such as lead, arsenic or antimony. Glasses with higher levels of heavy metal oxides usually have low softening temperatures and are higher than thin platelets
  • the object of the present invention is to provide a glass formulation which contains no toxic heavy metals, preferably has a refractive index> 1.65 and at the same time is chemically and mechanically stable. From this glass composition slightly dimensionally stable * ® glass plates should be produced. These glass flakes should be uncoated or coated for paints, coatings, plastics, printing inks, cosmetic formulations and as a filler and as a base substrate for effect pigments.
  • a further object of the present invention is to find glass compositions which have a strong absorption and / or a high scattering power for long-wave UV light (UV-A and UV-B) and in the form of thin platelets or finely divided spherical particles as a UV protective pigment, for example in sunscreens, in clearcoats, as a filler, are suitable. 5
  • Another object of the invention is to find glass compositions which have an intense body color and have a high covering power as thin platelets and / or show a metallic luster. 10
  • glasses with a high refractive index are obtained when the glass formulation has at least one crystalline phase of a high refractive index metal oxide.
  • the partial crystallization of individual glass components increases the refractive index of the glass composition compared to the amorphous state.
  • the softening temperature 20 of the glasses is increased by the formation of crystals, which is particularly important for the further processing of the glasses. If the crystalline phase is colored, glasses with interesting color effects can be produced.
  • the present invention thus provides a glass composition containing at least one crystalline phase, preferably a high-index metal oxide.
  • the invention likewise provides a process for the preparation of the glass composition and the use of the glasses, preferably in the form of glass flakes in paints, lacquers, powder coatings, plastics, in cosmetic formulations and as a base substrate for the production of effect pigments.
  • the essential component of the glass composition according to the invention is at least one crystallizable high refractive index metal oxide.
  • the crystallizable phase is at least one high refractive index metal oxide.
  • the crystallisable phase is anatase (TiO 2 ) and / or rutile (TiO 2 ). 5
  • Suitable crystallizable high refractive metal oxides are TiO 2 in the rutile modification, TiO 2 in the anatase modification, titanates, such as barium, strontium, calcium or Bismuttitanate, titanium suboxides, niobates, '5 such as sodium niobate, tantalates, tungstates, iron oxide, such as Hematite or magnetite, iron titanate such as ilmenite or pseudobrookite, or mixtures of said high refractive index metal oxides.
  • Particularly preferred high-index metal oxides are rutile and anatase.
  • the concentration of the high refractive crystallizable metal oxide component (s) in the inventive glass composition is preferably 3 - 70% by weight, in particular 15 -. 50% by weight and very particularly preferably 20 -. 40 wt.%.
  • the glass composition contains 3-70% by weight of anatase (TiO 2 ), rutile (TiO 2 ),
