The present inventors have discovered that amine oxides are highly effective as wood preservatives. The present invention provides a wood preservative composition comprising a biocidally effective amount of one or more amine oxides. Preferably, the wood preservative composition is substantially free of halogenated compounds (such as halides and chlorinated compounds) and quaternary ammonium compounds. The wood preservative composition of the present invention exhibits low toxicity, high stability in water, low corrosivity to metal substrates (such as steel substrates), excellent penetration and uniform distribution into wood, low odor, waterproofing properties, and high leaching resistance. The wood preservative composition may be applied to the surface of a wood substrate or be applied by pressure treating the wood substrate with the wood preservative composition. Other cellulosic and fiber materials, such as cotton, burlap, and like materials, may be preserved with the composition of the present invention. Another embodiment is a method of controlling microorganisms, such as fungal decay organisms (generally known as white rot, brown rot, and soft rot fungi) and sapstain organisms, on and/or in a wood substrate, such as fresh cut lumber, comprising applying a biocidally effective amount of the composition of the present invention to the wood substrate.
本发明者发现胺氧化物作为木材防腐剂非常有效。本发明提供了一种木材防腐剂组合物,其中包含一种或多种生物杀菌有效量的氧化胺。优选地,木材防腐剂组合物基本上不含卤代化合物(如卤化物和氯化化合物)和季铵化合物。本发明的木材防腐剂组合物毒性低、在水中稳定性高、对金属基材(如钢基材)的腐蚀性低、在木材中的渗透性好且分布均匀、气味低、防水性能好、抗浸出性强。木材防腐剂组合物可以涂抹在木材基材的表面,也可以用木材防腐剂组合物对木材基材进行压力处理。其他纤维素和纤维材料,如棉花、麻布和类似材料,也可以用本发明的组合物进行防腐处理。另一个实施方案是一种控制木材基材(如新伐木材)上和/或木材基材中的微生物,如真菌腐朽生物(一般称为白腐菌、褐腐菌和软腐菌)和边渍生物的方法,包括向木材基材施用生物杀菌有效量的本发明组合物。
