POLYSACCHARIDE-BASED IMPREGNATED SOLID MATERIAL WITH IMPROVED STABILITY, METHODS FOR PREPARING SAME, AND IMPREGNATING SOLUTIONS USED

摘要

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.
