Abstract

The invention relates to the field of fire fighting and extinguishing, and discloses an ultrafine dry powder fire extinguishing agent and a preparation method thereof. The fine dry powder fire extinguishing agent comprises the following raw material components in mass percent: 0.2% to 0.4% of sodium dodecylbenzenesulfonate, 8 to 12% of mica powder, 3.5 to 6% of hydrophobic white carbon black, 0.6 to 0.9% % of polyether modified silicone oil, 0.15-0.3% of hydrogen-containing silicone oil, 0.15-0.25% of water, 0.3-0.5% of gasoline, and the remaining materials are magnesium hydroxide and aluminum hydroxide, of which magnesium hydroxide and aluminum hydroxide The mass ratio is (1:0.9)~(1:1.5); the preparation method is mainly realized by multiple mixing and stirring, the process is simple, and the cost is low; the prepared ultrafine dry powder fire extinguishing agent forms a cold aerosol fire extinguishing agent after being sprayed with compressed gas , the average particle size is less than 5μm, which has more excellent fire extinguishing efficiency.

Description

technical field [0001] The invention relates to the field of fire fighting and fire extinguishing, in particular to an ultrafine dry powder fire extinguishing agent and a preparation method thereof. Background technique [0002] Ultrafine dry powder fire extinguishing agent is defined in GA578-2005 as a dry powder fire extinguishing agent with a particle size below 20 μm. At present, the similar superfine dry powder cold aerosol fire extinguishing agent sold on the market is mainly ABC superfine dry powder fire extinguishing agent based on ammonium polyphosphate (APP). The price of the material ammonium polyphosphate is high, and the cost of the fire extinguishing agent is also high, which increases the cost of fire extinguishing for users or armed police. Contents of the invention [0003] The object of the present invention is to provide a kind of ultrafine dry powder fire extinguishing agent and preparation method thereof, this dry powder fire extinguishing agent is ba...
