  • the layers were applied using customary paint application methods such as rolling, pouring or spraying.
  • the viscosities of these polyester paints are adjusted to a viscosity in the range from about 150 to 250 mPa.s at 21 ° C. so that they are sprayable.
  • the polyester lacquers can be applied by compressed air spraying, with the polyester and peroxide components being mixed using the intermixing method and sprayed from a pot. It is also possible to run the two-component spray process, the peroxide component and the polyester component separately to the gun and mix in there in the spray jet.
  • the wooden base is used for spray painting by pickling, priming, if necessary patinating and Isolate prepared. After drying, the polyester lacquer layer is sprayed onto the substrate prepared in this way.
  • the sprayed polyester paints thixotropize so that they also adhere to vertical surfaces.
  • they contain inorganic and / or organic thixotropic agents.
  • the individual layers are gelled and UV-cured by UV radiation.
  • the intermediate gelation and intermediate curing takes place through the radicals released from the peroxide component by UV radiation and, depending on the setting of the radiation, takes about 10 to 30 minutes for each individual layer.

  • the shrinking parts that are released into the atmosphere in polyester / styrene systems consist predominantly of monostyrene or of styrene oxide, which is formed from monostyrene during the polymerization. Both substances are volatile organic compounds (VOC), which are undesirable in the sense of VOC regulations. Cyclohexanone, which arises from the cyclohexanone peroxide used for the polymerization, is also undesirable.
  • the polyester layer contains more or less volatile constituents, which are also gradually released.
  • volatile constituents which are also gradually released.
  • these are phthalates and solvent residues.
  • the VOC value as a measure of the volatile constituents, is around 1,500 ppm for the above-mentioned gloss coating systems and around 1,700 to 2,200 ppm for polyester coatings containing paraffin.

  • radiation-curable acrylate lacquers have been applied by customary lacquer application methods, for example by thin-layer application by means of rollers, the layer thicknesses of the applied layers being 5 to 15 ⁇ m. These thin layers are also applied in several layers, gelled and sometimes even sanded. The intermediate gelling, which is necessary for the adhesion of the next layer, is achieved by UV radiation.

On the other hand, to ensure good film properties of the end product, high-molecular components must also be present.
  • the coating composition contains about 5 to 75% by weight of a reactive diluent.
  • the reactive diluents are monomers or also low-viscosity oligomers that replace volatile organic solvents. They have molecular weights in the range from about 50 to 500.
  • the reactive diluents which contain radical-polymerizable radicals, are selected from the group of acrylic esters of simple alcohols, hexanediol diacrylate, hydroxymethylethylacrylate, hydroxypropyl acrylate, polyethylene glycol diacrylate, trimethylolpropane triacrylate, dipropylene glycol diacrylate or mixtures of the same, tripropylene glycol.
  • Styrene-free unsaturated acrylate and polyester acrylate resins are available, for example, from BASF under the trade names Laromer® and Sartomer®.
  • a thixotropic agent based on silicon dioxide is added to adjust the thixotropy of the coating agent.
  • fumed silica is preferred in an amount of 0.5 to 1.5% by weight.
  • the thixotropic agent is combined with the resins or resin components of Van der Waals bonds, which bring about a reduction in viscosity under the action of mechanical forces during processing. After the mechanical stress has ceased, the thixotropy is reset, thereby preventing vertical surfaces from running off.
  • photoinitiators which are added in an amount of about 0.01 to 10% by weight, preferably 1 to 3% by weight. These are compounds which, under the action of high-energy radiation, form start radicals which trigger the polymerization of the coating composition.

  • Stabilizers or inhibitors which intercept potential start radicals.
  • the amounts used are of the order of about 0 to 20% by weight, preferably from 0 to 8% by weight.

  • the coating agent of the present invention is a material that has no short-life pot life.
  • the polymerisation is only triggered by the action of UV radiation by UV initiators.
  • the consequence of this is that sprayed material, which for example reaches the conveyor belt, is recyclable and can be recycled by appropriate devices.
  • the functionality of the reactive diluents and thus their crosslinking action is, in addition to the viscosity, the dilution action and volatility, an important selection criterion when using the same. If stabilizers remain in the product during manufacture, the paint properties must not be impaired. At most UV initiators are emitted from the product.

Abstract

L'invention concerne des agents de revêtement durcissables aux UV, à base d'acrylate, appropriés pour la réalisation de revêtements sur des pièces en bois. Cet agent de revêtement contient 5 à 80 % en poids de résines d'acrylate; 5 à 75 % en poids d'un diluant réactif; 0,1 à 5 % en poids d'un agent thixotropique; 0,1 à 10 % en poids d'un photo-initiateur et 0,05 à 20 % en poids d'additifs. L'invention concerne également un procédé pour réaliser des revêtements. Ce procédé consiste à appliquer 4 à 8 couches, par pulvérisation à chaud, sur des pièces en bois préfabriquées, puis à les faire durcir au moyen d'un rayonnement UV. Il importe de mentionner que les pièces revêtues dégagent peu d'émissions, après leur durcissement final, et présentent des valeurs de composés organiques volatils inférieures à 100, qui se situent à un niveau nettement inférieur aux valeurs usuelles des peintures à base de polyester connues.
