    摘要： A process for flameproofing wood is claimed, which comprises treating the wood with aqueous preparations which contain(a) at least one water-soluble ammonium salt of a non-volatile inorganic acid, e.g. ammonium sulfate or ammonium phosphate,(b) at least one water-soluble cationic reaction product of dicyandiamide, formaldehyde, optionally an ammonium salt and/or an alkylenepolyamine containing at most 18 carbon atoms, or the acid salt thereof.Components (a) and (b) are applied in succession or preferably simultaneously and the wood is subsequently dried. The flameproof finish obtained is resistant to rinsing. The wood provided with the flameproof finish is used in particular as mine timber.
