Abstract

Un article en bois est soumis à un passage sous vide dans une autoclave afin de retirer l'air qu'il contient. Puis, une solution contenant un prepolymère réticulable et hydrosoluble, un initiateur de polymérisation et, éventuellement, un produit de préservation du bois est introduite dans l'autoclave. La polymérisation permettant de créer un réseau polymère dans l'article en bois est réalisée dans une atmosphère qui peut être sensiblement exempte d'oxygène; le produit de conservation éventuellement ajouté étant fixé au bois de manière chimique. Ce procédé permet d'obtenir un article en bois présentant une diminution permanente de la dureté et une teneur en eau plus importante en équilibre.
