Abstract:

The flame resistant material is obtained by the inorganic flame-retardant,which has the advantage of economical and low toxic characteristic, in order to reduce the combustive property of wood. The treatment method and effect of the inorganic flame-retardant agent with different consistency and prescripton under normal pressure are studied. The experiment uses the dipping process for the wood and takes the retardant treatments by the flame retardants such as NH4H2PO4、BaCl2、MgCl2、Borax、Boric acid and so on. The wood has the good effect of antiflaming，which is evaluated in the passage, through the dipping process by the mixtures of NH4H2PO4、Borax and Boric acid. In the end, it gets the best craft condition by the experiment that: the under normal pressure the retting temperature is 80℃, the liquid of mixtures ride is 20% , the time of retting is 12 h.
