Patent
CA 2644653
The invention concerns a polysaccharide-based solid material comprising, in its mass, at least one active agent having bactericidal, fungicidal, insecticidal and/or as flame retardant properties, and at least one complexing agent and/or at least one polymeric matrix including a complexing agent. The active agent consists of at least one compound selected among the group consisting of boron, silica, aluminum, phosphorus, iodine, derivatives thereof, aluminosilicate derivatives, and mixtures thereof. The solid material is characterized by its improved stability and by a reduced environmental impact, and enables wood particle- or wood-based materials having a particular resistance to environmental stresses such as moisture, to be prepared.
Une matière solide à base de polysaccharides comprenant, dans sa masse, au moins un agent actif ayant des propriétés bactéricides, fongiques, insecticides et/ou comme retardateur de flamme, et au moins un agent complexant et/ou au moins une matrice polymérique comprenant un agent complexant. L'agent actif est constitué d'au moins un composé choisi dans le groupe constitué par le bore, la silice, l'aluminium, le phosphore, l'iode, leurs dérivés, les dérivés aluminosilicates, et leurs mélanges. La matière solide se caractérise par une stabilité améliorée et par un impact environnemental réduit, et permet de préparer des matériaux à base de particules de bois et des bois présentant une résistance particulière face aux agressions environnementales comme l'humidité.
