Abstract

The invention relates to a super-fine dry powder fire extinguishing agent. The super-fine dry powder fire extinguishing agent comprises the raw materials including, by weight percentage, 10-15% of sodium bicarbonate dry powder, 10-15% of potassium salt dry powder, 10-15% of ammonium dihydrogen phosphate dry powder, 10-15% of diammonium phosphate dry powder, 10-15% of phosphoric acid dry powder, 10-15% of amino group dry powder, 8-10% of mica powder, 5-8% of hydrophobic white carbon black powder, 8-10% of polyether modified silicone oil, 1-3% of magnesium hydroxide powder and 1-3% of aluminum hydroxide powder. The materials are adopted to be matched, and super-fine dry powder fog sprayed out under the effect of pressurizing gas makes contact with and is mixed with flames to extinguish fire. Compared with a common dry powder fire extinguishing agent, the fire extinguishing capacity of the super-fine dry powder fire extinguishing agent is 8-10 times that of the common dry powder fire extinguishing agent.

Description
