Definitions

  • Formaldehyde-containing adhesives are frequently used as binders, for example urea-formaldehyde resins or melamine-containing urea-formaldehyde resins.
  • the resins are produced by polycondensation of formaldehyde with urea or melamine. In order to obtain good adhesive properties, an excess of formaldehyde is generally used. This can lead to free formaldehyde in the finished wood material. By hydrolysis of the polycondensates additional formaldehyde can be released. The free formaldehyde contained in the wood material and the formaldehyde released by hydrolysis during the lifetime of the wood material can be released to the environment.
  • Coated wood-based materials generally have lower emissions of formaldehyde than uncoated substrates ("Wood as Raw Material", Volume 47, 1989, page 227).
  • Formaldehyde may cause allergies, skin, respiratory or eye irritation above certain limits in humans.
  • the reduction of formaldehyde emission in interior components is therefore an important concern.
  • WO 2004/085125 A2 describes a method for reducing the emissions of bonded wood materials, in which mixtures of aldehyde- and isocyanate-reactive substances are applied to the straightened edges lying perpendicular to the direction of adhesive bonding. It should be retained both from the wood as well as from the adhesive escaping pollutants.
  • substances which have an amino or amide group or hydroxyl-containing substances can be used. For example, urea, guanamine, ethylamine, ethanolamine, proteins, alcohols and carbohydrates are mentioned.
  • JP 2002-273145 A describes a method for reducing the formaldehyde emissions of wood composites, in which a plurality of measures, each individually suitable for reducing the formaldehyde emission, are combined.
  • the described aqueous formaldehyde scavenger is composed of 20 to 50 wt .-% urea, and a Residual of a non-volatile amine, a means to increase the permeability of the wood so that the urea and the non-volatile amine can penetrate into the composite, and a film-forming solid which, upon drying, becomes a physical barrier to the formaldehyde on the wood composite. This film can affect the coatability of wood composites.
  • Such open areas can be found, for example, as holes in shelf walls or in furniture rear walls, which are required to ensure a flexibly adjustable height of the shelves.
  • the edges of shelves that are not directed into the living area usually not surface-coated and thus open. For some shelves, even the entire underside of the shelf is uncoated, which thus presents open surfaces from which formaldehyde escapes.
  • the solution of the problem is based on the known methods for reducing the formaldehyde emission in wood materials by applying nitrogen-containing compounds.
  • the inventive method is then characterized in that (i) a mixture comprising at least one polyamine and optionally up to 20% by weight, based on the mixture, of urea is applied to the wood-based material;
  • polyamine is applied to or in the chip or fiber cake; (iii) is applied to the coating substrate polyamine used for the surface treatment and / or
