Definitions

  • the present invention relates to light to white wood-based panels made of bleached wood fibers and / or mass colored with a white pigment.
  • MDF panels medium-density fiberboards
  • HDF panels high-density fibreboards
  • MDF and HDF boards can be processed like conventional chipboard. Due to their uniform structure, they are also suitable for the production of profiled parts and are therefore becoming increasingly popular in furniture construction. Thus, for example, furnishings for rooms and for decorative purposes (for example in trade fair construction), but also higher-quality furniture made from these plates and closing to get the wood-like structure visible, only colorless coated or coated with overlay.
  • MDF boards are produced at much higher temperatures (about 2OfJ 0 C) than paper, which in addition to the brown inherent color of wood fibers enters a process-related browning, which is due to the oxidation and thermal decomposition of wood ingredients.
  • the light exposure of a MDF board incorporated in furniture is significantly longer and more intense than the usual papers and causes a not inconsiderable yellowing.
  • the invention therefore an object of the invention to provide light or white wood-based panels available
  • the wood-based panels according to the invention are distinguished by their brightness or their white color. Depending on the combination of measures taken, the desired whiteness can be easily adjusted. Especially white plates were ⁇ the e.g. by bleaching the wood fibers and mass-coloring with a dispersion of a white pigment which additionally contains optical brighteners. Bright plates with a lower degree of whiteness are also accessible merely by bleaching the wood fibers or by mass coloration with a white pigment.
  • the wood-based panels according to the invention may be MDF or HDF boards or chipboards. Particularly preferred are MDF boards.
  • MDF and HDF boards are usually produced in a continuous process.
  • washed, water-moist, small chopped pieces of wood (Hack ⁇ schnitzel) are first preheated to about 80 0 C and then in a digester under a Pressure of 2 to 5 bar and a temperature of 100 to 150 ° C soaked. In the adjoining refiner, the chips are then shredded.
  • the refiner consists of two metal discs with radial relief, which rotate close to each other in the opposite direction. The fibers leave the refiner via the so-called blowline.
  • the glue is usually applied.
  • Urea-formaldehyde resins some of which are reinforced with melamine, or urea-melamine-formaldehyde resins used for damp-resistant boards, are usually used as binders. Isocyanates are also used as binders. The binders are usually applied to the fibers together with the desired additives (eg hardener, paraffin dispersion, colorant). The glued fibers then pass through a dryer in which they are dried to humidities of 8 to 15 wt .-%. Occasionally, the dried fibers are also subsequently coated in special, continuously operating mixers.
  • the desired additives eg hardener, paraffin dispersion, colorant
  • the glued fibers or chips are then poured into mats, where appropriate cold precompressed and pressed in heated presses at temperatures of 170 to 24O 0 C to plates.
  • Bleached wood fibers are differentiated in the production of one embodiment of the light wood-based panels according to the invention (hereinafter, the term “wood fibers” and “chips” are not differentiated; rather, the term “wood fibers” is also intended to include “chips”).
  • the coloring impurities of the wood are destroyed or rendered ineffective by oxidizing and / or reducing chemicals.
  • oxidative bleaching e.g. Hydrogen peroxide, ozone, oxygen and salts of organic and inorganic peracids, such as peracetates, percarbonates and perborates, especially their alkali metal salts, in particular sodium salts, the percarbonates and hydrogen peroxide being preferred.
  • reductive lead there are e.g.
  • reducing sulfur compounds such as dithionites, disulfites, sulfites or sulfur dioxide, sulfinic acids and their salts, in particular the alkali metal salts and especially the sodium salts, and hydroxycarboxylic acids, such as citric acid and ⁇ pfel ⁇ acid suitable.
  • Preferred reducing agents are the disulfites and sulfites, in particular sodium hydrogen sulfite, and malic and citric acids.
  • wood fibers which have been firstly oxidatively and then reductively bleached are particularly preferred.
  • the oxidative bleaching is carried out with percarbonates or hydrogen peroxide and the reductive bleaching with sulfites, malic or citric acid.
  • the process is in bleaching expediently so before that aqueous, 5 to 40 wt .-% strength wood fiber dispersions continuously men inellese- at temperatures from 90 to 150 0 C and pressures up to 3 solutions bar with aqueous Lö ⁇ or dispersions of the bleaching agent treated.
  • aqueous, 5 to 40 wt .-% strength wood fiber dispersions continuously men inellese- at temperatures from 90 to 150 0 C and pressures up to 3 solutions bar with aqueous Lö ⁇ or dispersions of the bleaching agent treated.
  • it is carried out in the presence of complexing agents, such as EDTA, to avoid the degradation of the bleaching agents by transition metal ions.
  • the bleaching of the fibers is carried out in particular in the case of MDF / HDF boards during board production.
  • the bleaching agents can be added to the wood chips in the preheater or in the cooker.
  • complexing agents are also added.
  • all fibrous materials to be obtained from plants can serve as the base material for the wood-based panels according to the invention.
  • Preferred base materials are light wood species, especially spruce or pine, but darker wood species such as beech can also be used.
  • the use of bleached wood fibers with a mass coloration is combined with a white pigment.
  • the whiteness can be decisively improved.
  • the mass coloration with the white pigment can also be carried out alone. In this case, bright plates are also obtained.
  • the term "white pigment” includes both inorganic pigments which are preferred, such as titanium dioxide (rutile, CI Pigment White 6), calcium carbonate and calcium / magnesium mixed carbonates (eg dolomite), zinc oxide, zinc sulfide, lithopones and Sodium-aluminum silicates, as well as white-coloring, highly light-scattering plastic emulsions and dispersions.
  • titanium dioxide rutile, CI Pigment White 6
  • calcium carbonate and calcium / magnesium mixed carbonates eg dolomite
  • zinc oxide zinc oxide
  • zinc sulfide lithopones
  • Sodium-aluminum silicates eg.g., Sodium-aluminum silicates
  • white pigment is titanium dioxide.
  • mixtures of white pigments can also be used.
  • the white pigments are preferably used in the form of aqueous dispersions in which they are finely divided, since they can be introduced directly into the MDF / HDF production process via the blowline, separately from or together with the glue.
  • These pigment dispersions may contain further customary auxiliaries, in particular wetting and dispersing agents, defoamers and biocides, but also antisettling agents, water retention agents and rheology modifiers and are preferably prepared by wet milling of all components, for example in a stirred ball mill.
  • a further increase in the whiteness can be achieved by the addition of optical Aufhel ⁇ learning compensated by their bluish fluorescence (complementary color) Vergrau ⁇ ments and yellowing.
  • Suitable are, in principle, all blue emitting fluorescent dyes, more commercially accessible products such as Ultraphor ® (BASF), Leucophor ® (Clariant) or Tinopal ® (Ciba), linked from the chemical substance classes of the stilbenes, distyrylbiphenyls, coumarins, naphthalimides and double bonds benzoxazole and benzimidazole systems.
  • Ultraphor ® BASF
  • Leucophor ® Clariant
  • Tinopal ® Tinopal ®
  • optical brighteners can be introduced in the form of aqueous dispersions or solutions separately or together with the white pigments and the glue in the MDF / HDF production process.
  • the concentration in the finished wood-based panel is generally from 0.01 to 1% atro, preferably from 0.08 to 0.2% atro.
  • any resulting from the inventive measures changes in the physical properties of the pressed wood-based panel can be controlled by selecting the glue quality and amount of glue.
  • the brightness difference .DELTA.L was determined as a standard by coloristic measurement according to CIELAB in comparison to a MDF board produced analogously from unbleached wood fibers and without the addition of white pigments and optical brighteners.
  • the wood pulp mash was separated from the liquid constituents via a sieve with a mesh size of 1 mm and briefly washed out with running water and blown through. The spread filter material was then dried at 60 0 C in a convection oven for 3 days.
