Problems solved by technology

[0004] However, although the extremely fine powder particle size brings excellent fire extinguishing performance to the ultrafine ABC dry powder fire extinguishing agent, at the same time, due to the small particle size and high surface energy of the powder, it has a high moisture absorption rate. It is easy to agglomerate in the fire extinguishing agent, which leads to a sharp decline in the performance of the fire extinguishing agent, and the production cost is high and the storage time is short, so it has not been widely promoted yet.

Abstract

The invention relates to the technical field of fire extinguishing agents, in particular to an ABC dry powder fire extinguishing agent and a preparation method thereof. The ABC dry powder extinguishing agent comprises the following components in parts by weight: 77-82 parts of ammonium dihydrogen phosphate, 10-15 parts of quartz sand, 1-3 parts of activated clay, 1-2 parts of hydrophobic white carbon black, 1-2 parts of mica powder and 0.5-1 part of silicone oil. The preparation method for the ABC dry powder extinguishing agent comprises the following steps: firstly crushing ammonium dihydrogen phosphate and hydrophobic white carbon black, then adding activated clay, hydrophobic white carbon black and mica powder, carrying out stirring and dehumidifying, and finally adding silicone oil for hydrophobic treatment. Thus, the prepared ABC dry powder extinguishing agent is low in water content and moisture absorption rate, and has the characteristics of excellent fire extinguishing performance, low production cost and long shelf life.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to an ABC dry powder fire extinguishing agent and a preparation method thereof. Background technique [0002] Dry powder fire extinguishing agent is a kind of fine solid powder with dry and good fluidity, mainly composed of one or more fine inorganic powders with fire extinguishing ability and various additives.
