Definitions

  • the present invention relates to modified fillers, in particular to silicate fillers from the group of the layers or phyllosilicates, which have been treated with silanes to modify their properties, cf. for example EPPlueddemann, Silane Coupling Agents, Plenum Press New York (1982), Chapter 7, pp. 167-205.
  • Silanes are generally used to improve the adhesion between filler and polymer. As an adhesion promoter, they result in improved mechanical strength and chemical resistance of the composite.
  • the filler surface interacts with the polymer via catalytic activity, orientation of molecular segments and other modifications of the polymer morphology at the phase interface, see AT-B-263973, GB-A-2038302, GB-A-2052458.
  • the surface modification of fillers also influences the rheological properties by changing the wetting, dispersion, viscosity, thixotropy and flow behavior in the binder.
  • the modification increases the binding forces in the boundary layer by reaction or better application of polymer segments and by removing any inhibitor effects of the filler the curing of the polymer.
  • an increased probability of breakage in brittle resins or fillers can eliminate or obscure recesses by modifying the surface of the surface. For example, soft fillers in hard polymers hardly bring any improvements despite modification.
  • Such brittle polymers include thermoplastic acrylic resins, methacrylate-styrene copolymers, various epoxies, polypheiryl sulfides, polystyrenes (hard), styrene-acrylonitrile copolymers (SAN) and others.
  • a silene modification of soft fillers is particularly advantageous for flexible resins and rubber. Harder fillers can be added to increase their strength.
  • thermoplastics for example in PE methacrylate silane systems.
  • Inhibitor effects with regard to the hardening of the composite occur primarily on metadl oxide surfaces, but also silicate surfaces (such as talc, mica etc.) can inhibit peroxide hardening. This reduction in the crosslinking exotherms can be prevented by silane modification (for example in the case of unsaturated polyesters).
  • the modification of the fillers also affects their dispersibility. Likewise, the viscosity of a medium containing the filler is changed by modifying the fillers with silanes, although a reduction in viscosity is generally to be expected, but acid-base properties play an important role. Neutral polymers require surface-active additives for a good dispersion, each polar additive lowers the viscosity. Acidic additives for basic fillers and basic additives for acidic fillers are used. Acidic fillers include silica gel, quartz, kaolin; basic fillers are, for example, talk (weak), calcite , Magnesite, aluminum hydroxide. The relative acidity of a filler is determined by its isoelectric point in the water.
  • Acidic fillers in basic polymers and basic fillers in acidic polymers result in good dispersibility without sap.
  • Lewis acids titaniumates are suitable for acidic fillers in basic polymers, but not for basic fillers in acidic polymers.
  • Acid fillers in acidic polymers and basic fillers in basic polymers require additives.
  • Cationic silanes or Lewis acids give the best results with acidic fillers in acidic polymers and some improvement with basic fillers in basic polymers.
  • Neutral silanes that have been modified with catalytic amounts of amines or titanates are generally more effective than pure silane.
  • Surface-active additives also increase the coupling power of neutral silanes.
  • the present invention thus relates to the use of trialkoxysilanes containing amino, epoxy, imidazoline, succinic anhydride, cyclohexyl, urea and / or vinyl groups, alone or in combination, of silicate fillers from the group of the layered or phyllosilicates , especially based on talc, chlorite and mica, in anti-corrosion varnishes, spray fillers and stoving stone fillers.

  • the amount of the silane applied according to the invention can expediently be up to about 2%, based on the dry weight of the filler.
  • the special silanes can be applied to the fillers by special methods, for example the slurry method in which the filler to be treated is treated with a suitable solvent, e.g. Ethanol, isopropanol or white spirit, mixed to a pulp and the coating agent (coating agent) dissolved in the solvent is added. After stirring in, the resulting slurry is carefully homogenized. Subsequent standing and drying results in the coated filler. Another manufacturing process involves stirring the coating agent in the diluted or undiluted state and homogenizing it in a high-performance stirrer. Finally, the dissolved silane can also be sprayed directly onto the filler moved in an air stream.
  • a suitable solvent e.g. Ethanol, isopropanol or white spirit
  • the fillers coated according to the invention have unexpectedly advantageous properties.
  • a silanization of talc or Plastorit ® (magnesium-potassium-aluminum-silicate), chlorite and mica with a trialkoxysilane having a substituent of the above-mentioned type results in a marked improvement in the resistance to corrosion, as measurements in the case of these coated fillers in corrosion protection lacquers based on aqueous epoxy resin systems Confirm salt spray test.
  • Coated talc fillers show an analogous behavior in alkyd resin systems.
  • Talc varieties coated according to the invention have also been found in spray fillers unsaturated polyester resins or PU resins compared to uncoated fillers have been shown to be significantly better in terms of flow properties and surface properties as well as in terms of mechanical properties such as impact resistance.

  • the filler aftertreated according to the invention leads to a significant improvement in the paint properties of a stoving filler for motor vehicles based on a water-soluble polyurethane resin, such as the comparison of test formulations below (approach 1: with filler coated according to the invention; approach 2: uncoated filler according to the prior art ) and show the results obtained with it.
