  • Process for treating wood for increasing the lifetime thereof and wood thus obtained
    Patent number: 8304087
    Abstract: Process for treating wood consisting in injecting in cavities of the wood a solution of at least one fungicide and/or bactericide and/or insecticide and at least one monomer that can progressively form a polymer matrix in the cavities of the wood and then a gel in the cavities of the wood. The treated woods thus obtained exhibit an improved lifetime.
    Type: Grant
    Filed: February 20, 2008
    Date of Patent: November 6, 2012
    Assignee: Hydro-Quebec
    Inventors: Michel Perrier, Jean-Francois Labrecque, Michel Robitaille, Louis Gastonguay
  • Polysaccharide-based impregnated solid material with improved stability, processes for the preparation thereof and impregnating solutions used
    Patent number: 8298582
    Abstract: A polysaccharide-based solid material including, in its mass, at least one active agent having bactericidal, fungal, insecticidal and/or flame-retardant properties, and at least one complexing agent and/or at least one polymeric matrix having a complexing agent. The active agent includes at least one compound selected from the group including boron, silica, aluminum, phosphorus, iodine, derivatives thereof, aluminosilicate derivatives, and mixtures thereof. The solid material is characterized by an improved stability and by reduced environmental impact, and makes it possible to prepare materials based on wood particles and woods having a particular resistance against environmental attacks such as moisture.
