Definitions

  • the present invention relates to a process for the preparation of nanoscale additives containing nanodispersed polyester resins as binders for powder coatings.
  • the invention further relates to a method for producing a powder coating formulation and a powder coating formulation itself.
  • Powder coatings have been widely used due to the high cost-effectiveness of the process and the favorable assessment from the point of view of environmental protection when coating materials such as metal, glass, ceramics, etc.
  • powder coatings which contain nanoparticles are provided, for example, by EP 1 164 159 AI, EP 1 361 257 AI and WO 02/051922 A2.
  • Nanoscale particles come very close to this endeavor. Due to their extremely high specific surface (area / mass, e.g. m 2 / g), they are highly effective wherever, for example, it is about interacting with electromagnetic radiation from the environment via their surface or by means of diffusion a constant flow of material to the surrounding matrix. In addition, they can be evenly distributed in other substances down to the submicroscopic range, which within such a material leads to a property profile that is orders of magnitude more homogeneous than the distribution of microscale particles. Due to their special delicacy, they are not only invisible as such, the substances they contain often do not even have a cloudiness and appear transparent. Due to quantum effects, nanoparticles usually have new and different properties than the micro- and bulk materials of the same chemistry.
  • Nanoparticulate titanium dioxide and zinc oxide absorb UV radiation even at concentrations that are irrelevant from a coloristic point of view. Relocated coatings are able to reliably and - in contrast to organic UV absorbers, which degrade over time - permanently shield the surface from high-energy and material-damaging UV rays.
  • Nanocrystalline tin-doped indium oxide (ITO) has a number of special properties in accordance with the brochure “NRC Trade Trends”, Issue 2, October 2002, page 15 by Nordmann, Rassmann GmbH, which relate to an ITO called Nano®ITO such as transparency, coupled with electrical conductivity, antistatic, electromagnetic shielding and adsorption / reflection of heat radiation.
  • Nano®ITO which is given by the dealer, can be used to refine polymers or varnishes by incorporation and these with attractive properties such as electrical conductivity, Equip antistatic or largely impermeable to heat radiation.
  • nanoscale ferrite particles absorb microwaves scaled silver particles are able to due to their high specific surface to emit a steady stream of silver ions to the matrix surrounding them and to provide them with an antimicrobial effect.
  • biocidal treatment of a powder coating which, as disclosed, for example, in US Pat. No.
  • 5,980,620 A is equipped with an organic biocide homogeneously distributed in the coating matrix, for example a polychlorinated aromatic compound as active ingredient, the extremely fine, but heterogeneously distributed, nanoscale silver particles the guarantee that the biocidal effect of the powder coating equals the life of the coating, since a loss of the effect due to migration of the particles to the surface with subsequent loss of active ingredient is excluded and the particles, as long-term studies have shown, are not consumed over the years.
  • Nanoscale zirconium dioxide, silicon dioxide, aluminum oxide, barium sulfate as well as corresponding clay minerals are able to give powder coating formulations a significantly improved hardness and scratch resistance.
  • Nano®ITO IR-absorbing powder coating material
  • a powder coating formulation which otherwise corresponded to the prior art. It was expected that due to the absorption behavior, such a powder coating formulation should be curable particularly quickly and / or with reduced radiation output by IR radiation.
  • the powder coating raw materials used - binder components, pigments, filler, additives such as leveling agents and hardening accelerators - together with the state-of-the-art Nano®ITO were first thoroughly mixed in a high-speed mixer and then extruded; the introduction of the particles into the powder coating was therefore also carried out in analogy to that referred to in the aforementioned WO 02/051922 A2 as "melt extrusion"("meltextrusion") Method.
  • the further course of the production of the powder coating and its application and curing on sample sheets in an IR curing system proceeded according to the prior art.

  • the described ultrasonication of the particles in a low-viscosity liquid is certainly much more efficient for the production of a nanodisperse sol than the methods of the three aforementioned documents.
  • the disadvantage of the compositions produced by the process described is that after the powder coating has been applied and stoved on, a further coating system is required in order to obtain coatings with scratch resistance and hardness.
  • Another disadvantage is that this additional coating to be applied is a liquid system, so that in addition to a system for applying powder coating, another is required for applying a liquid system.
  • a transfer of the above process to powder coatings is not a viable option, since it is not possible to dissolve the powder coating binders which are solid at room temperature and the above-mentioned coating sols, as is the case with the compositions disclosed.
  • Nanoparticles that are obtained in powder form agglomerate very easily. Nanoparticles in such agglomerates are often irreversibly bound to one another and can only be brought into a nanodisperse state with great effort, if at all, using conventional methods. Since only solid raw materials can be used in powder coating production, it is economically impossible to incorporate nanoparticles nanodispersed in powder coatings. However, nanoparticles are often produced in liquid media, which means that nucleation and growth can be precisely controlled. In the liquid phase, the nanoparticles can be prevented from agglomeration and stable nanodisperse liquids can be produced. However, such liquids cannot be used in the production of powder coatings according to the prior art.
  • the present invention has for its object to provide a method according to which nanoparticulate additives - as functional carriers - can be incorporated in such a way in polyester resins serving as binders for powder coatings and subsequently in powder coating formulations that they are efficiently distributed and therefore allow economical use of those additives.
  • Another object of the invention is to provide powder coatings which are visually and uniformly represented in their paint properties.
  • the object of providing a corresponding method for producing nanoscale additives containing polyester resins in a nanodispersed distribution as binders for powder coatings is achieved according to the invention by introducing the nanoscale additives in the form of a suspension in a liquid outer phase into the reaction mixture in the course of resin synthesis.

  • the invention also relates to a process for producing a powder coating formulation based on polyester resins as a binder component and, if appropriate, pigments, fillers and additives customary for powder coatings.
  • this method is characterized in that polyester resins which contain nanoscale additives in nanodisperse form are used in accordance with the method according to one of claims 1 to 24. If polyester resins produced in accordance with the invention in this way are used for the production of powder coatings, this results in the possibility of efficiently equipping powder coatings with functionality-creating nanoparticles with a significantly lower amount of material compared to the “dry” method described above, the powder coatings that can be produced therewith being visual and functional in terms of their coating technology Properties are uniform.
  • the invention also relates to a powder coating formulation based on polyester resins as a binder component and, if appropriate, pigments, fillers and additives which are customary for powder coatings, which powder coating formulation is characterized in that it contains nanoscale additives in a nanodispersed distribution in the binder matrix. Only the nanodisperse distribution allows maximum use of the nano-specific properties.
  • Polyester resins as binders for powder coatings have been state of the art for decades. According to the raw materials used, they are primarily carboxyl and / or hydroxyl functional and can be used, for example, in combination with polyfunctional epoxy or isocyanate compounds or else ß-hydroxyalkylamides for the production of heat-curable powder coatings.
  • An example is DE 2 163 962 AI, which discloses thermosetting powder coatings based on carboxyl-functional polyesters.
  • DE 2 105 777 A1 discloses heat-curable powder coatings based on hydroxyl-functional polyester.

  • dispersions in which - according to the examples - the surface of the silicon dioxide particles have been organically modified by reaction with alkoxysilanes can, according to the disclosure of this document, be used as a filler for the production of polymeric materials with high contents of amorphous silica.

  • EP 1 236 765 AI does not provide information on how nano®ITO or other highly specific and efficient nanoparticles can be introduced nanodisperse in powder coatings in such a way that the potential of these particles can be exploited to the best possible extent and inhomogeneities which are recognizable - often in small amounts - are added to these particles the resulting powder coatings can be avoided.
  • the flowable outer phase of the dispersions used according to the invention is water in the simplest way. Since numerous nanoparticles are produced in aqueous solutions using wet chemical methods, water is particularly obvious as the outer phase. The majority of the water fed to the reaction mixture with the dispersion leaves the reactor, in part as steam from the start of the esterification reaction and thus increases the amount of by-product water obtained during the esterification.
  • Solvents which are neutral in the synthesis of the polyesters according to the invention represent a further group of liquids which can be used according to the invention. Examples are aromatic hydrocarbons, lower alcohols, ethers or else Ketones. However, their use is less preferred for ecological as well as economic reasons. As previously described for water, solvents are also removed from the batch by evaporation.
  • the flowable outer phase can be liquid substances which are used as reaction participants in the polyester synthesis anyway.
  • these are diols which are liquid at room temperature, such as ethanediol 1,2, propanediol 1,2 and propanediol 1,3, 2-methylpropanediol 1,3, butanediol 1,4, pentanediol 1.5 and 3-methylpentanediol 1.5.

  • esters of dicarboxylic acids with lower alcohols for example dimethyl adipate, dimethyl glutarate or dimethyl succinate.
  • the inner esters of hydroxycarboxylic acids such as ⁇ -caprolactone or ⁇ -butyrolactone also offer themselves as an external flowable phase. These reactants are predominantly - except for the alcoholic components of carboxylic acid esters - built into the resulting resin, so there is hardly any need to evaporate liquids, which is advantageous in terms of energy requirements for resin production.
  • the dispersions required for the use of the nanoscale additives according to the invention can usually be obtained from the manufacturer of these substances and represent the preferred source for nanodisperse preparations. Where this is not possible in individual cases, the user himself can also produce corresponding dispersions in suitable liquid phases with good success become. Suitable dispersing machines for this are, for example, dissolvers or bead mills, possibly in combination with ultrasound. The state of the art is described for example by A. Goldschmidt / H.-J. Streitberger, BASF manual for coating technology, Vincentz-Verlag, 2002. In a “bottom up” synthesis, nanoparticles are preferably produced and stabilized directly nanodisperse by nucleation and controlled growth in the liquid phase. This prevents agglomeration from the start.

Melted nanoledge) and heating to a maximum of 140 ° C under a nitrogen atmosphere. The further procedure for the production of the polyester was then completely analogous to Comparative Example A. The finished resin ultimately had an acid number of 72.8 mg KOH / g polyester resin and had a content of 0.03% C nanotubes.
