Abstract (en)

[origin: WO02081159A2] The invention relates to a method for the protective treatment of wood, derived timber products and wood-type substrates by means of thermal treatment at 60-250°C and additional treatment using an amine and/or amine derivative of general formula (Ia), (Ib) or (Ic) wherein R<1> and R<4> independently represent C6-24 alkyl; R<2> and R<3> independently represent C1-24 alkyl or (CH2)-NH2; R<5>, R<6>, R<8> and R<9> independently represent C1-24 Alkyl; R<7> represents C6-24 alkyl or benzyl; R<10> independently represents C1-24 alkyl or -[(CH2)2-O]nR<11> where n=1-20; R<11> represents hydrogen or optionally substituted phenyl; and X<-> represents a monovalent inorganic or organic anion or an equivalent of a polyvalent inorganic or organic anion. The additional treatment can also be carried out using a corresponding salt. The wood treated according to said method has good resistance even to harmful organisms which cannot be reliably controlled by means of only a heat treatment. The inventive method is carried out without compounds containing heavy metals and the wood treated in this way has no impact on the environmental either during the use or during the disposal thereof.
