Definitions

  • the invention relates to a lubricating varnish based on polyimide.
  • a resin-bound Lubricant coating known. It is on the abrasive cleaned Surface of the machine parts applied a resin-bound lubricant and cured, so that it comes to a cross-linking of the resin.
  • suitable Resins are phenolic resins, epoxy resins, polyimide resins, polyamide-imide resins, Polyesters, acrylates, polyphenylenes, ethylenes, propylenes or Be polymethylpentenes.
  • suitable solid lubricants are Fluoropolymers such as polytetrafluoroethylene (PTFE) fluorinated Ethylene-propylene copolymer, perfluorinated alkoxy resins, polyvinylidene fluorides, Polychlorotrifluoroethylene, ethylene chlorotrifluoroethylene copolymer and Polyvinyl fluorides and tungsten disulfides, molybdenum disulfides and titanium disulfide specified.
  • PTFE polytetrafluoroethylene
  • Ethylene-propylene copolymer perfluorinated alkoxy resins
  • polyvinylidene fluorides Polychlorotrifluoroethylene
  • ethylene chlorotrifluoroethylene copolymer and Polyvinyl fluorides and tungsten disulfides, molybdenum disulfides and titanium disulfide specified.
  • the invention has the object of providing a lubricating varnish based on polyimide specify, compared to known from the prior art bonded coatings already without a content of solid lubricants a friction-reducing Shows and compared to the solvent-based anti-friction coatings has economic and environmental benefits.
  • the object is achieved by a lubricating varnish based on polyimide dissolved, the at least one Polyimidprepolymerharz in aqueous dispersion contains.
  • the lubricious varnish contains polyimide prepolymer resins based on bismaleimide resins having a melting point in the Range of 70 to 130 ° C and an average molecular weight in the range of 1000 - 7000 g / mol.
  • Solid lubricants such as molybdenum disulfide, graphite, polytetrafluoroethylene (PTFE) per part by weight of polyimide prepolymer resin.
  • a Coating varnish in which the weight ratio of polyimide prepolymer resin to Solid lubricant in the range of 9 to 1 to 1 to 4, preferably 5 to 1 to 1 to 1 lies.
  • the lubricating varnish according to the invention can also contain auxiliaries such as Wetting agents, thickeners, preservatives, adhesion promoters, defoamers contain.
  • the proportion of water in the inventive Coating dispersion is 40 to 80 parts by weight.
  • the use of the Gleitlackes invention is carried out in such a way that it on a Subject applied the water removed and the resulting varnish layer is cured by exposure to temperature at least 150 ° C.
  • the nature of Application does not matter, i.e., it can be the usual application methods like dipping, painting, spraying.
  • the invention ultimately also relates to objects with the Coated coating according to the invention are coated.
  • the invention is based on an embodiment and by comparison with commercially available solventborne bonded coats.
  • An exemplary lubricating varnish dispersion contains 58.55 parts by weight of water, 1.50 parts by weight of wetting agent for pigment and surface wetting, 2.5 parts by weight of thickener, 0.10 part by weight of preservative, 24.5% by weight Bismaleimide resin having a melting point of 90-110 ° C and an average molecular weight of 3000 to 5000 g / mol, 7.85 parts by weight of molybdenum disulfide, 2 parts by weight of graphite, 2 parts by weight of acrylic resin and 1 wt. Part defoamer.
  • the properties of the bonded coating according to the invention are shown in the table below compared to solvent-containing commercial comparative products, wherein the bonded coatings applied to a specimen produced a lubricating paint film by evaporation of the dispersion or solvent and the bonded coatings were cured by thermal treatment above 150 ° C.
