Embodiment 1
[0056] A kind of B-P-Mg-Si series density board flame retardant antifungal agent, raw material composition is as follows:
[0057] Sodium borate (Na 2 B 4 o 7 10H 2 O): 60 kg;
[0058] Ammonium polyphosphate ((NH 4 PO 3 ) n ): 80 kg;
[0059] Magnesium Hydroxide (Mg(OH) 2 ): 48 kg;
[0060] 40% ethanol solution of organic silicon quaternary ammonium salt: 30 kg, wherein the content of organic silicon quaternary ammonium salt is 12 kg.
[0061] Preparation method, the steps are as follows:
[0062] Dry sodium borate at 60-70°C for 6 hours, then mix it with 40% ethanol solution of organic silicon quaternary ammonium salt, stir for 20 minutes to make it evenly mixed, let it stand for 12 hours, then add ammonium polyphosphate and magnesium hydroxide respectively , stirred for 30min, that is.
[0063] Prepare flame-retardant and mildew-proof density boards 1A, 1B, and 1C by using a flame-retardant and anti-mold agent for density boards. The steps are as follows:
