Definitions

  • the present invention relates to particles with a functional multilayer structure based on substrates, characterized in that the substrates are coated with one or more layers of one or more polymers and one or more layers of one or more silanes, processes for their preparation and their use ,
  • Particulate materials are increasingly being used in a number of technical systems and materials, which can take on a variety of tasks in these systems. For example, they are used for corrosion protection, as a barrier, for mechanical reinforcement but also for coloring.
  • the particulate materials are used in a variety of different ways
  • Application media used such as Varnishes, paints, plastics, whereby the particulate materials have their own individual requirements.
  • the materials should be well compatible with the surrounding application medium, but must also be sufficiently stable for long periods.
  • platelet-shaped effect pigments based on platelet-shaped substrates are used in many ways for coloring, and in a whole series of application media that differ greatly from the composition.
  • a fundamental problem here is the tendency of platelet-shaped effect pigments to form agglomerates, in which the pigments lie in a stack-like manner and are difficult to separate again owing to strong adhesion. This is all the more serious since, when flake-like effect pigments are incorporated into application media, high shear forces must not be exerted because of the fragility of the thin flakes.
  • Compatibility of the particulate materials with the application media is not only problematic with platelet-shaped materials, but also with any particulate materials.
  • WO 99/51690 describes pigments with improved dispersing properties, one pigment, e.g. Graphite, coated with polyamides, polycarbonates, polyethers etc., and the use of these surface-modified pigments in inks, toners and plastics.
  • EP 0 703 192 describes crosslinked resin-coated SiO 2 particles comprising 0.6 to 17 ⁇ m-sized SiO 2 particles which are coated with a vinyl-containing silane in order to then radically polymerize a vinyl monomer to form a polymer.
  • Particles coated in this way serve as a means of controlling the thickness of a liquid crystal layer in an LCD display.
  • the coating therefore serves the sole purpose of ensuring that the particles function as a spacer, ie dispersion of these particles in the liquid-crystal medium is in no way desired. These particles are therefore unsuitable for use in paints, varnishes or plastics because they do not have sufficient dispersibility in these media.
  • the methods described for surface modification of particles for example the precipitation polymerization of a monomeric compound in the presence of the particles to be coated or the polymerisation of a monomer onto a functionalized surface, the so-called grafting-from methods (see EP 0 703 192) often fail due to insufficient bonding of the occupancy material on one already modified, eg silane-coated surface, on the necessary, complex functionalization of the surface or on the special requirements when carrying out the reaction, such as, for example, polymerization under a protective gas atmosphere.
  • the layer sequence is often not freely selectable, that is to say the layer sequence cannot be adapted to the requirements but has to be adapted to the process parameters.
  • the essential step is often not the silane modification, but the coating of the surface with polymers.
  • modified particles in the application media should be stable and, in particular in the case of pigments, should lead to a uniform coloring without changing the essential color properties or the gloss.
  • additional stabilization of the particulate materials, in particular in the case of platelet-shaped materials, is desired in order to enable their problem-free use even in applications with high mechanical or thermal loads.
  • the present invention accordingly relates to particles with a multilayer structure based on substrates, the substrates being coated with one or more layers of one or more polymers and one or more layers of one or more silanes are.
  • the present invention furthermore relates to processes for the production of these pigments and their use in paints, water-based paints, powder coatings, paints, printing inks, security elements, plastics, concrete, in cosmetic formulations, in agricultural films and tarpaulins and for the production of pigment preparations and
  • the particles according to the invention with a multilayer structure have the advantage that they can be individually adapted to the application medium with regard to their application properties.
  • the layers of one or more silanes perform a barrier function, the one or more polymer layers stabilize the particles against agglomeration but also against mechanical influences.
  • the compatibility of the particles with a matrix also consisting of polymers, for example with a binder matrix is significantly increased.
  • the multilayer structure proves to be stable, which means that the applied layers of silanes and polymers are not detached.
  • the products obtained are thus obtained in a purer form during production, so that a disruptive monomer content or complex cleaning can be avoided here.
  • the particles according to the invention with a multilayer structure are based on substrates, wherein the substrates can in principle have any shape, preferably they are platelet-shaped.
  • the substrates can in principle have any shape, preferably they are platelet-shaped.
  • platelet-shaped particles are mechanically loaded by shear forces when incorporated into applications.
  • These particles can be additionally stabilized by the layer structure of silanes and polymers according to the invention, which enables their use in mechanically demanding applications.
  • Suitable substrates are SiO 2 , TiO 2 particles, effect pigments, holographic pigments, pearlescent pigments, interference pigments, multi-layer pigments, metal effect pigments and / or BiOCI pigments, the substrates are preferably effect pigments, pearlescent pigments or metal layer pigments, interference pigments.
  • Effect pigments, pearlescent pigments, interference pigments, metallic effect pigments or multilayer pigments which can be used according to the present invention are based in particular on carriers, the latter preferably being platelet-shaped.
  • carriers the latter preferably being platelet-shaped.
  • platelet-shaped T1O 2 synthetic or natural mica, glass platelets, metal platelets, platelet-shaped SiO 2 , Al 2 O 3 or platelet-shaped iron oxide are suitable.
  • the metal platelets can consist of aluminum, titanium, bronze, steel or silver, preferably aluminum and / or titanium.
  • the metal platelets can be passivated by appropriate treatment.
  • the support is coated with one or more transparent, semi-transparent and / or opaque layers containing metal oxides, metal oxide hydrates, metal suboxides, metals, metal fluorides, metal nitrides, metal oxynitrides or mixtures of these materials.
