Micronized wood preservative formulations

摘要

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 biocide comprising a metal or metal compound and organic biocide. When the composition comprises an inorganic biocide and an organic biocide, the inorganic biocide 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.

主权项

1. Wood treated with an aqueous wood preservative composition, wherein said composition comprises:
(a) a biocidally effective amount of particles of a copper compound with a particle size of between 0.001 and 25 microns; and (b) a biocidally effective amount of one or more organic biocides,wherein the particles of the copper compound are distributed throughout the wood and render the wood resistant to fungal decay.
