Definitions

  • the invention relates to phosphonate functional particle-containing compositions, composite materials prepared therefrom and the use of the compositions.
  • Particles - especially nanoparticles - containing composite materials are state of the art.
  • Corresponding coatings of composite materials are described for example in EP 1 249 470, WO 03/16370, US 20030194550 or US 20030162015.
  • the particles lead to an improvement in the properties of the corresponding coatings, in particular with regard to their scratch resistance and optionally also their chemical resistance.
  • a common problem with the use of - usually inorganic - particles in organic matrix systems consists in a usually insufficient compatibility of particles and matrix. This can lead to the particles not being able to disperse sufficiently well in the matrix. In addition, even well-dispersed particles can settle at longer stand or storage times, possibly forming larger aggregates or agglomerates which can not or only poorly be separated into the original particles by an energy input. The processing of such inhomogeneous systems is in any case extremely difficult, often even impossible. Composite materials that have smooth surfaces after their application and curing can usually not be produced in this way, or can only be produced by cost-intensive processes.
  • particles which have on their surface organic groups, which to a lead to better compatibility with the surrounding matrix and thus suppress unwanted agglomeration or aggregation of the particles.
  • the inorganic particle is masked by an organic shell.
  • particularly favorable composite properties can often be achieved if the organic functions on the particle surfaces are also reactive with respect to the matrix, so that they can react with the matrix under the respective curing conditions. It is thus possible to chemically incorporate the particles into the matrix during the curing of the composite, which often results in particularly good mechanical properties but also in an improved form
  • a disadvantage is the inadequate stability despite masking of the nanoparticles used in the prior art.
  • This insufficient stability of the particles occurs on the one hand in the processing of the particles, in particular when concentrating the particle dispersions or a solvent exchange, on the other during the storage of the uncured particle dispersions to light.
  • Indications of a lack of stability of the particles are an increase in viscosity, or the sedimentation of the particles, which often progresses until gelation.
  • the described nanoparticles can not be isolated as redispersible solids due to the high agglomeration or aggregation tendency.
  • the particles which can be produced according to the prior art fall on isolation, for example by spray drying, as
  • Particle agglomerates or aggregates which also under energy input, for example by means of a bead mill or by ultrasonic treatment, not to achieve redispersing the original primary particle size.
  • the surface-modified particles contained in the composite materials are prepared by reacting particles having free silanol (SiOH) or metal hydroxide functions with alkoxysilanes or their hydrolysis and condensation products containing unreactive groups, e.g. Alkyl or aryl radicals, or reactive organic functions, e.g. Vinyl, (meth) acrylic, carbinol, etc. included.
  • the silanes used in the art for particle functionalization are typically di- or trialkoxysilanes.
  • siloxane shell is formed around the particle in the presence of water after hydrolysis and condensation of the resulting silanols.
  • Macromol. Chem. Phys. 2003, 204, 375-383 the formation of such a siloxane shell around a SiO 2 -
  • the problem here may be that the siloxane shell formed still has a large number of SiOH functions on the surface.
  • the stability of such SiOH functional particles is among the
  • particle-reinforced paints which are described, for example, in EP 0 768 351, EP 0 832 947, EP 0 872 500 or DE 10247359, represent a particularly important type of composite material.
  • Surface-modified particles are used as reinforcing fillers have sufficient compatibility with the paint matrix. By introducing the surface-modified particles, in particular the scratch resistance of paints can be significantly increased.
  • the handling of the particles is extremely difficult due to their described limited stability.
  • it is not possible to isolate the particles since the agglomerates which form in the course of the drying do not revert back to the original particle size, i. the size of the primary particles, can be separated.
  • the mechanical hardnesses - and in particular the scratch resistance - of the particle-reinforced coatings are not sufficient for many applications.
  • a coating resin of hydroxy-functional prepolymers in particular of hydroxy-functional polyacrylates and / or polyesters, used in the paint curing with an isocyanate-functional hardener (polyurethane coatings) and / or a melamine (melamine) for reaction to be brought.
  • the polyurethane coatings are characterized by particularly good properties. In particular, polyurethane coatings have superior chemical resistance, while melamine coatings generally have better scratch resistance.
  • these types of paints are used in particularly high-quality and demanding fields of application, for example as clearcoats or topcoats for OEM coatings in the automotive and vehicle industry. Likewise, most automotive refinish topcoats are of such systems.
  • the layer thicknesses of these coatings are typically in the range from 20 to 50 ⁇ m.
  • the former consist of two components, one of which consists essentially of the Isocyanathärter, while the paint resin is contained with its isocyanate-reactive groups in the second component. Both components must be stored and transported separately and may only be mixed shortly before processing, since the finished mixture has only a very limited pot life. Often cheaper, therefore, are the so-called 1K systems, which consist of only one component in which there is a hardener with protected isocyanate groups in addition to the paint resin.
  • 1K coatings are thermally cured, whereby the protecting groups of the isocyanate units are cleaved off and the deprotected isocyanates are then cleaved with the Resin can react.
  • Typical baking temperatures of such 1- component paints are 120-160 ° C.
  • Melamine paints are generally 1-component paints, and the baking temperatures are typically in a comparable temperature range.
  • a particularly advantageous way of achieving this object is the use of particles which have on their surface organo-functions which are reactive with the paint resin or with respect to the hardener.
  • Such particles with suitable organ functions are already known in principle. Like their use in coatings, they are described, for example, in EP 0 768 351, EP 0 832 947, EP 0 872 500 or DE 10247359.
  • the scratch resistance of paints can be significantly increased by the incorporation of such particles.
  • the corresponding coatings have such high particle contents that the use of such paints in large series finishes will be difficult to realize, for reasons of cost alone.
  • paint-containing paint systems are described, which are characterized in that there are more particles in a surface segment of the paint than in a bulk segment.
  • the advantage of this particle distribution is the comparatively low particle concentration, which is needed for a significant improvement in the scratch resistance.
  • the desired high affinity of the particles to the paint surface is achieved by applying a silicone resin as a surface-active agent to the particle surfaces.
  • a disadvantage of this method is the fact that not only the silicone resin modification of the particles, but also the preparation of the silicone resins required for this purpose is itself technically complex. The latter is particularly problematic because it is necessary to achieve a good scratch resistance, the silicone resins with
