Definitions

  • the invention relates to a method for producing a transparent coating agent for the coating of wood with special etter and light-protecting properties.
  • Field of application is the coating of wooden facades, windows, doors, wooden cladding and the like.
  • glazing or colorless coatings are used to protect wood, high-energy radiation from the sun spectrum leads to degradation reactions in the paint film. But also the lignin in the underlying wooden surface is destroyed and in combination with moisture leads to the removal of the colorless lacquer film.
  • US Pat. No. 5,338,613 describes photopolymerizable polyurethane acrylates for weather-resistant coatings.
  • Organic UV absorbers and pigments are added to the paint to stabilize the light.
  • the organic UV absorbers absorb the photonic energy, they have the disadvantage that their effectiveness decreases over time and thus pass on the absorbed light energy to the lattice of the polymer binder and in this way leads to a light-induced degradation of the polymer in the long term.
  • paint formulations containing pigments are less suitable for wood coatings, because on the one hand they hide the wood grain and on the other hand they tend to flake off after being used for more than 5 years.
  • UV shielding Another protective measure against damaging UV radiation is UV shielding.
  • the principle of action of this method is the complete shielding of UV radiation by adding UV-absorbing iron oxide pigments.
  • these iron oxide pigments have the decisive disadvantage of coloring and covering properties, so that they are not suitable for producing colorless coatings.
  • coatings containing iron oxide are difficult to crosslink with UV light. As already mentioned, they also tend to peel off the paint film and chalk out the pigment after only a few years.
  • the invention has for its object to provide a manufacturing method for a largely weather and UV stable wood coating agent.
  • a method for producing a transparent coating agent for the coating of wood in which a binder is selected from the group consisting of the physically drying acrylic resins or radiation-curing acrylic resins and then doped with at least one highly efficient and light-stable laser dye, which is in the form of 0.1 - 5.0% by weight, based on the total composition, is dissolved in the binder in a molecularly disperse manner and the UV component of the UV light and spectral light components in the wavelength range between 280 nm and 500 nm are absorbed completely or selectively and with a conversion efficiency of> 30% in converts undulating radiation which does not damage the wood substrates and the binder, at least one photoinitiator, auxiliary substances and optionally solvents being added.
  • methylbenzoylforma Irgacure 184, Irgacure 819 or P37 (benzophenone derivative) are used as the photoinitiator, alone or in combination, other photoinitiators also being conceivable.
  • UV-curing polyurethane acrylates can be used as the acrylate resins.
  • An alternative solution according to the invention based on another binder is a process for producing a transparent coating agent for the coating of wood, in which a binder is selected from the group of medium to long oil alkyd resins based on drying fatty acids and / or drying oils and then with at least a highly efficient and light-stable laser dye is doped, which is dissolved in the form of 0.1 - 5.0% by weight based on the total composition in the binder in a molecularly disperse manner and the UV component of the UV light and spectral light components in the wavelength range between 280 nm and 500 nm completely or selectively absorbed and with a conversion efficiency of>. 30% is converted into longer-wave radiation that does not damage the wood substrates and the binding agent, with additives and possibly solvents being added.
  • the coating according to the invention also provides high light protection in the blue spectral range and is light-stable.
  • the coating systems according to the invention can be crosslinked using the economical technology of radiation curing (for example by means of UV radiation).
  • the coatings are transparent so that the wood grain can take full effect and is not covered by pigments.
  • the production technology of the layers is economically efficient and easy to implement.
  • the layer thickness of the paint to be coordinated with the concentration of the respective laser dye.
  • the at least one laser dye is to be matched to the intended use and is selected from special rhodamines, pyrro ethenes, exalites, furan or lumogens.
  • rhodamines rhodamine 560, rhodamine 575, rhodamine 590 and rhodamine 610 are particularly suitable.
  • Particularly suitable pyrromethenes are pyrromethene 546, pyrromethene 556, pyrroethene 567, pyrromethene 580, pyrromethene 597 and 1,4-di [2- (5-phenyloxazolyl)] benzene.
  • Exalit 428, Exalit 400E, Exalit 404, Exalit 411, Exalit 417, LD466, LD473 and LD489 have proven to be particularly suitable.
  • Preferred Lumogens are Lumogen F240, Lumogen F Red 300, Lumogen F Violet 570 and Lumogen F Yellow 083.
  • one or more laser dyes can be used in combination with an organic UV absorber.
  • Flow additives, wetting additives or the like can be considered as auxiliary substances. Fillers can also be added to reduce the price of the coating agent.
