1. , a kind of wood fire retardant and Wood fire retardant treatment process thereof comprise fire retardant, Wood fire retardant treatment process, it is characterized in that it is formulated at normal temperatures by raw materials by weight percent, and its pharmaceutical formulation Wood fire retardant treatment process is as follows:

  • A, prescription and the preparation method ammonium sulfate 5-65% diammonium hydrogen phosphate 5-65% boric acid 5-65% borax 5-65% that 1. fills a prescription;

    2. preparation method'"'"'s ammonium sulfate, diammonium hydrogen phosphate, boric acid, borax are put agitator in order respectively into, and after fully mixing, its former powdery transfers more dried pasty state to, is fire retardant;

    B, Wood fire retardant treatment process 100kg water adds the 10-20% fire retardant, be made into fire resistant fluid, earlier timber is put into the sealing fermentation vat, take out air in it, making fermentation vat is vacuum, preparing fire resistant fluid by on No. 1 fermentation vat timber of high-pressure pump input, repeatedly several times, when being in the 0.6-0.8mpa stable state, the gauge hand of No. 1 fermentation vat or No. 2 fermentation vats do not reduce pressure in 10 minutes, simultaneously, when the water gauge water level shows that being higher than immersion timber does not fall after rise, prove that the inside and outside fire resistant fluid of its timber has reached saturation state, enter drying stage, this moment, unnecessary fire resistant fluid was imported No. 2 fermentation vats by high-pressure pump, and the processing method of No. 2 fermentation vats is with No. 1 fermentation vat, and the unnecessary fire resistant fluid of same No. 2 fermentation vats is imported No. 1 fermentation vat by high-pressure pump, or adopt the fermentation vat more than 2 to recycle simultaneously, in use to note replenishing not enough new fire resistant fluid.
