Abstract:Baker-etanoilaminski zaščitni pripravki za les uspešno nadomeščajo klasične pripravke na osnovi bakra in kroma. V prispevku so opisani osnovni mehanizmi vezave, podrobneje pa je predstavljenih nekaj dejavnikov, ki vplivajo na izpiranje bakrovih učinkovin iz lesa. To so sestava in koncentracija pripravka, čas in temperatura vezave, uporabljena drevesna vrsta in postopek zaščite. Številni rezultati kažejo, da etanolamin bistveno izboljša vezavo bakrovih učinkovin v les, po drugi strani pa kasneje lahko povzroči tudi depolimerizacijo lesnih polioz, kar se kaže v intenzivnejšem izpiranju bakra iz lesa.

Title:Leaching of copper-ethanolamine based preservatives from wood
Abstract:Copper-ethanolamine based preservatives are successfully replacing classical copper-chromium based preservative solutions. In this paper, the proposed fixation mechanisms are described. Additionaly,basic facts that influence copper leaching from wood are elucidated: composition and concentration of solutions, time and temperature of fixation as well as wood species and treatment method used. The results show that addition of ethanolamine significiantly improves copper fixation, but can on the other hand cause depolymerisation of wood polymers, which results in increased leaching of copper.
Keywords:wood preservation, copper based preservation, amines, ethanolamine, fixation, leaching, fungicidal properties
