Problems solved by technology

Although the parameters of the ABC superfine dry powder fire extinguishing agent sold in the market can meet the requirements of GA578-2005, its particle size is still too large, and the submerged fire extinguishing effect is not ideal
The main materials used are ammonium dihydrogen phosphate and ammonium sulfate, which are very easy to absorb moisture and agglomerate. In the process of preparing the fire extinguishing agent, the process requirements are high; the fire extinguishing agent is easy to form hard lumps in harsh environments such as humidity and vibration, which makes the fire extinguishing agent ineffective.

Embodiment 1

[0020] The preparation of ABC superfine dry powder fire extinguishing agent specifically comprises the following steps:

[0021] Step 1, each raw material component is taken by weighing 1 ton of total raw material: 30kg of mica powder (90% particle diameter is less than or equal to 10 μm), 35kg of hydrophobic fumed silica, 10kg of high boiling silicone oil, 8kg of water, 11kg of gasoline, the rest is ethylenediamine phosphate (90% particle size is less than or equal to 10μm).

[0022] In step 2, the mica powder and ethylenediamine phosphate are dried separately, mixed and stirred evenly to obtain intermediate material A.

[0023] Step 3: Mix high-boiling silicone oil with water and stir, then add gasoline and stir to obtain emulsion B.

[0024] Step 4: spray emulsion B into the stirred intermediate material A after atomization, mix and stir at 95°C, perform surface coating treatment, and evaporate excess gasoline, water and other volatile components to obtain intermediate mat...

Abstract

The invention relates to the field of fire fighting and extinguishing, and discloses an ABC superfine dry powder fire extinguishing agent and a preparation method thereof. The fire extinguishing agent comprises the following raw material components in mass percent: 3-5% mica powder, 3-6% hydrophobic fumed silica, 0.9-1.5% high-boiling silicone oil, 0.8-1.5% water, 1-6% 1.5% gasoline, the balance is ethylenediamine phosphate. 90% of the prepared ABC superfine dry powder fire extinguishing agent has a particle size less than or equal to 12 μm, and its performance meets the relevant requirements of GA578-2005 superfine dry powder fire extinguishing agent, and can realize total submersion fire extinguishing with good submersion fire extinguishing effect. Moreover, the dry powder fire extinguishing agent has excellent water repellency and long storage period, and is especially suitable for being used as a fire extinguishing agent for water-based and dry powder compound jet fire extinguishing equipment.

Description

technical field [0001] The invention relates to the field of fire extinguishing, in particular to an ABC superfine dry powder fire extinguishing agent and a preparation method thereof. Background technique [0002] At present, the ABC dry powder fire extinguishing agents sold on the market are mainly used for fire extinguishing of Class A, Class B and Class C fires. Ultrafine dry powder fire extinguishing agent is defined in GA578-2005 as a solid powder fire extinguishing agent with 90% particle size less than or equal to 20 μm. Although the parameters of the ABC superfine dry powder fire extinguishing agent sold in the market can meet the requirements of GA578-2005, its particle size is still too large, and the submerged fire extinguishing effect is not ideal. The main materials used are ammonium dihydrogen phosphate and ammonium sulfate, which are very easy to absorb moisture and agglomerate. In the process of preparing the fire extinguishing agent, the process requiremen...
