Abstract

L'invention concerne un procédé pour le traitement protecteur du bois et de matériaux à base de bois, ainsi que de substrats semblables au bois, consistant en un traitement thermique à 60-250 °C et en un traitement complémentaire avec une amine et/ou un dérivé d'amine correspondant à la formule générale (Ia) ou (Ib), ou bien (Ic). Dans ces formules: R1 et R4 représentent, indépendamment l'un de l'autre, alkyle C¿6?-C24; R?2 et R3¿ représentent, indépendamment l'un de l'autre, alkyle C¿1?-C24 ou bien -(CH2)3-NH2; R?5, R6, R8 et R9¿ représentent, indépendamment l'un de l'autre, alkyle C¿1?-C24; R?7¿ représente alkyle C¿6?-C24 ou bien benzyle; R?10¿ représente alkyle C¿1?-C24 ou bien -[CH2)2-O]nR?11¿ où n = 1-20; R11 représente hydrogène ou phényle éventuellement substitué; et X représente un anion monovalent inorganique ou organique ou bien un équivalent d'un anion multivalent inorganique ou organique. Ledit traitement complémentaire peut être effectué avec un sel correspondant de ladite amine et/ou dudit dérivé d'amine. Les bois traités selon ce procédé présentent une bonne résistance également vis-à-vis des organismes nocifs qui ne peuvent pas être neuralisés de façon fiable avec seulement un traitement thermique. Ce procédé est mis en oeuvre sans composés contenant des métaux lourd et les bois ainsi traités ne créent aucune nuisance pour l'environnement, que ce soit pendant leur utilisation ou pendant leur élimination.
