Embodiment 1
[0014] Formula (parts by weight): ammonium polyphosphate (polymerization degree n is 200-1000) 100, potassium sulfate 18, sodium bicarbonate 18, magnesium chloride 8, mica 8, silicone oil 12, activated clay 8, coated red phosphorus 6, zinc borate 8. Antimony trioxide 8 and white carbon black 10.
[0015] Preparation method: take the above-mentioned raw materials in parts by weight, mix them and grind them until the particle size is ≤5 μm.
[0016] The fire extinguishing agent produced has a moisture content of 0.08-0.10%, a moisture absorption rate of 0.15-0.18%, a fluidity of ≤5s (expressed by the flow time after freezing at -20°C), an electrical insulation of ≥9.0kv, and is suitable for extinguishing Class A fires. Efficiency is 22~25g / m 3 , Class B fire extinguishing efficiency 22~25g / m 3 , Class C fire extinguishing efficiency 22 ~ 25g / m 3 , Class D fire extinguishing efficiency 22 ~ 25g / m 3 ; Compared with using water alone to extinguish the fire, the smoke is reduced...
