Problems solved by technology

The ABC superfine dry powder fire extinguishing agent sold in the market is mainly ABC superfine dry powder fire extinguishing agent based on ammonium dihydrogen phosphate. Although the parameters of the ABC superfine dry powder fire extinguishing agent can meet the requirements of the GA578-2005 standard, its The particle size is still large, the submerged fire extinguishing effect is poor, and the fire extinguishing efficiency is low; the main material used in it is ammonium dihydrogen phosphate, which is easy to absorb moisture and dissolve in water. In humid and vibrating environments, it is easy to form hard lumps and make the fire extinguishing agent ineffective

Embodiment 1

[0022] The preparation of ABC superfine dry powder fire extinguishing agent specifically comprises the following steps:

[0023] 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 remaining material is type II ammonium polyphosphate (90% particle size is less than or equal to 10 μm, and the degree of polymerization is greater than 1000).

[0024] In step 2, the mica powder and type II ammonium polyphosphate are dried separately and then mixed and stirred evenly to obtain the intermediate material A.

[0025] Step 3: Mix high-boiling silicone oil with water and stir, then add gasoline and stir to obtain emulsion B.

[0026] Step 4: Spray emulsion B into the stirred intermediate material A after atomization, mix and stir at 95°C, and evaporate excess gasoline, water...

Abstract

The invention relates to the field of fire fighting and fire extinguishing, and discloses an ABC ultrafine dry powder extinguishing agent and a preparation method thereof. The ABC ultrafine dry powder extinguishing agent comprises the following components in percentage by weight: 3-5% of mica powder, 3-6% of hydrophobic fumed silica, 0.9-1.5% of high-boiling silicone oil, 0.8-1.5% of water, 1-1.5% of gasoline, and the balance of type II ammonium polyphosphate. The preparation method disclosed by the invention is simple; the prepared ABC ultrafine dry powder extinguishing agent can satisfy the related requirements of a GA578-2005 ultrafine dry powder extinguishing agent, and has excellent submerging type fire-extinguishing effect; in addition, the storage period is long.

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 the standard GA578-2005 as a solid powder fire extinguishing agent with 90% of the particle size less than or equal to 20 μm. The ABC superfine dry powder fire extinguishing agent sold in the market is mainly ABC superfine dry powder fire extinguishing agent based on ammonium dihydrogen phosphate. Although the parameters of the ABC superfine dry powder fire extinguishing agent can meet the requirements of the GA578-2005 standard, its The particle size is still large, the submerged fire extinguishing effect is poor, and the fire extinguishing efficiency ...
