The present invention provides wood preservative compositions comprising micronized particles. In one embodiment, the composition comprises dispersions of micronized metal or metal compounds. In another embodiment, the wood preservative composition comprises an inorganic component comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic component and an organic biocide, the inorganic component or the organic biocide or both are present as micronized particles. When compositions of the present invention are used for preservation of wood, there is minimal leaching of the metal and biocide from the wood.
La présente invention concerne des compositions de produits de conservation du bois comprenant des particules micronisées. Pour un mode de réalisation, la composition comprend des dispersions de métal ou de composés métalliques. Pour un autre mode de réalisation, la composition de produit de conservation du bois comprend un composant inorganique contenant un métal ou un composé métallique et un biocide. Lorsque la composition comprend un composant inorganique et un biocide organique, le composant inorganique ou le biocide organique ou les deux sont présents sous forme de particules micronisées. Lorsque les compositions de l'invention sont utilisées pour la conservation du bois, le bois ne dégorge que de très petites quantités de métal et de biocide.
