Definitions

  • the present invention relates to means based on coal tar oil for the Protective treatment of wood. It also relates to a protective treatment procedure of wood using the agents according to the invention.
  • coal tar oil to protect wood against rotting and insect attack has been known since the middle of the 19th century and has been known for Conservation of masts, fences, sleepers etc. in use.
  • coal tar oil in the form of emulsions in water or aqueous Protective salt solutions (zinc salts, copper salts) apply. This form of application
  • tar oils continued to be the majority were used in the undiluted state.
  • homoogenization analogous to that in Milk
  • dispersers e.g.
  • a disadvantage of this known method is the fact that the emulsions are proportional are unstable and that the effective proportion of coal tar due to the emulsion is reduced by the proportion of water and the emulsifier (s), so that the The amount to be introduced must be increased in order to provide effective and lasting protection guarantee.
  • JP-A-56072502 describes compositions for wood protection treatment the Coal tar oil, quaternary Ammonium compounds and Contain water.
  • the object of the present invention was therefore the disadvantages of the known production processes and to eliminate or reduce applications of tar oil emulsions. According to the invention, this object is achieved by the means according to claim 1 and the Treatment method according to claim 6 solved.
  • the pungent smell of coal tar oil is particularly evident in two- and three-core Aromatics, e.g. B. naphthalene and alkylnaphthalenes. Leave this only partially separate by distillation, since after their complete removal a tar oil If the viscosity is too high and cannot be handled even at 100-120 ° C.
  • the Agents according to the invention also permit use by the nature of their preparation more viscous and thus highly deodorized tar oils, which is the use of coal tar oil also in sensitive areas, e.g. B. thresholds for subways, facilitated or makes it possible in the first place.
  • the agents according to the invention preferably contain to improve the (storage) Stability up to 20 parts of a polyglycol compound.
  • a polyglycol compound include, for example Polyethylene glycols and polypropylene glycols, as well as their alkyl and aryl ethers and esters.
  • Polyethylene glycol compounds such as, for example, are particularly preferred Polyethylene glycol, ethoxylated phenols and diethylene glycol monobutyl ether.
  • These preferably contain one or more constituents from the group of the resins, Binders, waxes, dyes and pigments.
  • Particularly preferred binders are alkyd resins and similar resins based on natural oils such as linseed oil or soybean oil, especially those that are reacted with Ethylene oxide or propylene oxide are water-soluble or water-dilutable.
  • the agents according to the invention contain to broaden the spectrum of action preferably additionally an effective amount of one or more insecticides, fungicides, Algicides or bactericides.
  • binders such.
  • B. drying alkyd resins, acrylates or others Polymers can improve the surfaces of the treated wood mechanically and optically, combined with a further reduction in mobility (leaching and Bleeding) of coal tar oil.
  • the systems according to the invention can still be used in contrast to coal tar oil by adding dyes or pigments alone Modify in such a way that the treated wood can be colored can.
  • By adding waxes it is possible to mattify the surfaces of the treated wood, combined with a strong water-repellent Effect that reduces the absorption of dripping water without the moisture exchange to hinder over the vapor phase.
  • This preparation forms stable, milky (opaque) or clear mixtures with a low viscosity that can be introduced into the wood with good penetration and without penetration by means of a boiler pressure process (application of vacuum and pressure).
  • a boiler pressure process application of vacuum and pressure.
  • the amount required for comprehensive protection of the wood is 20-80 kg / m 3 wood.
  • the agents according to the invention are preferably used in vacuum boiler pressure systems such that the means by means of pressure differences in the to be protected Wood.
  • the process steps include a pre-vacuum phase, a Flood phase, while maintaining the vacuum, and a pressure phase. If necessary the process is completed with a final vacuum. Control of the brought in Protective agent mass is made by weighing. For easily soakable woods or types of wood the water content in the compositions can be increased even further compared to the examples become.
  • the impregnation is preferably carried out without the addition of heat, that is to say approximately at ambient temperature. If necessary, the water introduced into the wood with the agents can be removed by heat treatment. If the preparations also contain polymers that are suitable for curing under the influence of elevated temperatures, the wood can be treated with superheated steam. This vaporization then leads to post-diffusion and more even distribution of the agents, combined with more effective fixation. Polyethylene glycols that may be present in the preparations give them a dimensionally stabilizing effect, combined with a significantly reduced tendency of the wood treated with them to crack.
