Embodiment 1

[0040] A BC dry powder fire extinguishing agent is composed of bistetrazole potassium salt, strontium nitrate, mica powder, activated clay, magnesium stearate, talcum powder, and organic silicon oil. The weight percentage of each component is calculated based on the total weight of the fire extinguishing agent for:

[0041]

[0042] Preparation process: firstly bake raw materials such as bistetrazole potassium salt and strontium nitrate with high moisture content, and then send them into an ultrafine pulverizer to grind them into particle size (D 70 ) for powders less than 40 microns, add weighed potassium salt of bistetrazole, crushed strontium nitrate and auxiliary raw materials magnesium stearate, activated clay, and mica powder into the mixer according to the formula, stir quickly and mix evenly, heat up, and add diluted For good silicone oil, add hydrophobic talcum powder after 10-15 minutes, continue to bake at a constant temperature until the material is discharged, ...

Embodiment 2

[0044] A BC dry powder fire extinguishing agent is composed of biguanide salt azotetrazole, sodium nitrate, potassium perchlorate, activated clay, talcum powder, white carbon black, and organic silicon oil. The weight percentage of each component is calculated based on the total weight of the fire extinguishing agent for:

[0045]

[0046]This dry powder fire extinguishing agent is prepared according to the similar method described in Example 1, wherein white carbon black and talcum powder are added at the same time.

Embodiment 3

[0048] A BC dry powder fire extinguishing agent is composed of azotetrazole sodium salt, lithium nitrate, potassium perchlorate, activated clay, talcum powder, white carbon black, and silicone oil. The weight percentage of each component is calculated based on the total weight of the fire extinguishing agent for:

[0049]

[0050] This dry powder fire extinguishing agent is prepared according to the similar method described in Example 2.

Abstract

The invention relates to a BC dry powder extinguishing agent. The BC dry powder extinguishing agent takes nitrate (perchlorate) of <+2> or (+1) metal ions or a mixture of the nitrate (perchlorate) and azole compounds as extinguishing base stock, can be widely used for extinguishing various combustible liquid and gas fire and also can be used for extinguishing electrical fire and solid surface fire. Compared with the sodium bicarbonate BC dry powder extinguishing agent generally used at present, the BC dry powder extinguishing agent disclosed by the invention has high extinguishing efficiency.

Description

technical field [0001] The invention relates to a dry powder fire extinguishing agent, which belongs to the technical field of fire protection. The dry powder fire extinguishing agent of the invention can be widely used to extinguish various combustible liquid and gas fires, and can also be used to extinguish electrical fires and solid surface fires. The dry powder fire extinguishing agent of the present invention can be loaded into various portable dry powder fire extinguishers, fire extinguishing bombs, fire extinguishing trucks, and fire extinguishing planes, and can also be used in solid fire extinguishing devices without pipe networks and fire extinguishing systems with pipe networks. Background technique [0002] The fire extinguishing base material of the existing BC dry powder fire extinguishing agent is mainly sodium bicarbonate, and there are also formulas using potassium bicarbonate, potassium chloride, sodium chloride, potassium sulfate, ammonium sulfate, monnex,...
