Definitions

  • the present invention relates to a method for the treatment of wood parts to improve their performance properties such. As hardness, water absorption and weather resistance.
  • wood is modified by impregnation with reactive monomers and subsequent crosslinking thereof.
  • Such methods are for. B. off WO 2006/117 159 A1 respectively.
  • the present invention therefore an object of the invention to develop a method for modifying wood parts in the form of wood or wood materials, which does not have the disadvantages of the prior art, but the known method for the thermal treatment of wood with an impregnation in the Improved manner that only small amounts of a toxicologically and ecologically harmless impregnating agent are needed and still obtain advantageous properties.
  • the wood parts in the form of wood or wood-based materials are first subjected to impregnation with cyanamide (step a)) and then to a heat treatment (step b)).
  • This low-priced hardwood and softwoods of moderate widths are treated, which preferably come from sustainable forestry.
  • Examples are the European woods spruce, fir, pine, birch, beech, such. European beech or hornbeam, maple, poplar, alder, linden, Douglas fir, ash and oak, as well as non-European woods with an analogous property profile.
  • the woods are preferably as solid wood (boards, planks, slats) before. But they can also be in the form of veneers or chips for subsequent use for the production of wood-based materials. Alternatively, finished wood materials (plywood, chipboard, wood fiber boards, OSB boards, glued wood) can be treated by the method according to the invention.
  • the said woods or wood-based materials are preferably impregnated by the application of vacuum and / or pressure with a cyanamide-containing solution. Suitable for this purpose are facilities such as are commonly used for the boiler pressure impregnation of woods.
  • the aqueous impregnating solution should contain 1 to 50% by weight of cyanamide, particularly preferably 5 to 25% by weight of cyanamide, in particular 10 to 15% by weight of cyanamide.
  • the pH of the impregnating solution should be in the range 3.0 to 7.0, preferably pH 4.0 to 5.5 or pH 4.5 to 5.0.
  • the impregnating solution may optionally contain further substances, the water-soluble wood preservatives known to the person skilled in the art in the concentration range of 0.01 to 5.0% by weight being preferred. Typical examples of such additives are, for. As fungicides, insecticides or biocides, such as.
  • borates As copper compounds, fluorides, borates, silicates, phenol, 1,2,4-triazoles, insecticidal phosphoric acid esters or neonicotinoid insecticides. To improve the flame resistance of wood or wood materials phosphates, borates or sulfamates can be added. In addition, pigments and / or dyes and / or ultraviolet light absorbers may be included.
  • the aqueous cyanamide solution further contains surfactants, preferably in an amount of 0.02 to 0.2 wt .-%, in particular 0.05 to 0.015 wt .-%.
  • surfactants preferably in an amount of 0.02 to 0.2 wt .-%, in particular 0.05 to 0.015 wt .-%.
  • the impregnation (step a)) is suitably carried out in a temperature range between 0 and 60 ° C, in particular 20 to 40 ° C.
  • a vacuum 0.02 to 0.98 bar
  • pressure (1.02 to 15 bar)
  • a complete impregnation of the wood with the impregnating solution can be achieved become.
  • a 1- to 5-fold alternation of pressure and vacuum treatment can take place.
  • Corresponding methods are known to the person skilled in the art.
  • the woods impregnated in this way are optionally subjected to a heat treatment after drying.
  • the optional drying of the impregnated with the aqueous cyanamide wood can be carried out at temperatures of 20 to 150 ° C, preferably at 40 to 130 ° C, wherein the external pressure, if necessary, by applying a vacuum to 0.01 to 1.0 bar is set.
  • the drying time is several hours, preferably 1 to 24 hours.
  • the drying is initiated by the action of the temperature and pressure conditions provided for the heat treatment, in which case a sliding transition to the heat treatment takes place.
  • the temperature range of the heat treatment is between 130 and 250 ° C, preferably 150 to 220 ° C, in particular 170 to 200 ° C.
  • the duration of the heat treatment is 1 to 36 hours, with times between 2 and 12 hours or 4 to 8 hours being preferred.
  • the drying and subsequent heat treatment is preferably carried out in several temperature stages, wherein said temperature is gradually approached.
  • the heat treatment can be carried out without pressure, but possibly also under a pressure of up to 10 bar, for example at 3 to 7 bar, wherein the atmosphere may preferably contain air, nitrogen, water vapor or a mixture thereof.
  • the treated woods After the heat treatment, the treated woods have a residual moisture of preferably less than 10%. They can be used as such as construction timbers, such. As for load-bearing or non-structural components of buildings, doors, windows, furniture (especially garden furniture) and wood elements in horticulture. Alternatively, the treated woods (especially in the form of veneers, chips, etc.) can be used for the production of wood-based materials, which in turn can be used for the applications mentioned.
  • the invention treated wood parts are characterized by very good performance properties such. As high hardness, low water absorption and very good weather resistance.
  • test specimens were immersed in cyanamide solution (or water as reference) and completely impregnated by evacuation twice. Then it was dried at 60 ° C in a vacuum.
  • Test specimens which had been impregnated with water or with 10% strength by weight cyanamide solution according to Example 1 were thermally post-treated at 160 ° C. (8 hours) or at 200 ° C. (3 hours). The weights of the specimens were used to record the water uptake or release as well as the cyanamide uptake (see Figure 2 ).
  • Example 2 woods were tested for hardness. This resulted in: Species impregnation heat treatment hardness Spruce without Drying at 60 ° C low Spruce without Heat treatment 200 ° C, 3 hours medium Spruce with 10% cyanamide solution Drying at 60 ° C low Spruce with 10% cyanamide solution Heat treatment 200 ° C, 3 hours high birch without Drying at 60 ° C medium birch without Heat treatment 200 ° C, 3 hours high birch with 10% cyanamide solution Drying at 60 ° C medium birch with 10% cyanamide solution Heat treatment 200 ° C, 3 hours very high
  • Example 2 woods were immersed for 7 days at 20 ° C in water.
  • the water absorption (as mass%) or the volume increase of the specimens was determined (see Figures 3 and 4).
  • Wood specimens according to Example 2 were exposed to the weather. After a residence time of 12 months, the weather resistance was estimated.
  • Species impregnation heat treatment weatherability Spruce without Drying at 60 ° C low Spruce without Heat treatment 200 ° C, 3 hours medium Spruce with 10% cyanamide solution Drying at 60 ° C low Spruce with 10% cyanamide solution Heat treatment 200 ° C, 3 hours high birch without Drying at 60 ° C low birch without Heat treatment 200 ° C, 3 hours medium birch with 10% cyanamide solution Drying at 60 ° C low birch with 10% cyanamide solution Heat treatment 200 ° C, 3 hours high
