Embodiment 1

[0065] An ABC dry powder fire extinguishing agent is composed of 1,5-diaminotetrazole, strontium nitrate, potassium perchlorate, potassium dihydrogen phosphate, mica powder, activated clay, magnesium stearate, and talcum powder, wherein the total weight of the fire extinguishing agent is Calculate, the weight percentage of each component is:

[0066]

[0067] Brief description of the preparation process: firstly bake raw materials such as 1,5-diaminotetrazole, strontium nitrate, potassium dihydrogen phosphate, potassium perchlorate and other raw materials with high moisture content, and then send them into an ultrafine pulverizer to grind them into particle sizes (D 50 ) powders smaller than 40 microns. Mica powder, activated clay, magnesium stearate, talcum powder and other auxiliary materials are also pulverized into (D 50 ) powders smaller than 40 microns for use. Add weighed 1,5-diaminotetrazole, strontium nitrate, potassium dihydrogen phosphate, potassium perchlorate...

Embodiment 2

[0069] An ABC dry powder fire extinguishing agent is composed of potassium tetrazolium salt, potassium perchlorate, ammonium metaphosphate, activated clay, talcum powder, and white carbon black, wherein, based on the total weight of the fire extinguishing agent, the weight percentage of each component for:

[0070]

[0071] The dry powder fire extinguishing agent is prepared according to the method described in Example 1, wherein the white carbon black is added together when the talcum powder is added.

Embodiment 3

[0073] An ABC dry powder fire extinguishing agent is composed of azotetrazole sodium salt, lithium nitrate, ammonium metaphosphate, activated clay, talcum powder, white carbon black, and organic silicon oil, wherein, calculated by the total weight of the fire extinguishing agent, the The weight percentage is:

[0074]

[0075]

[0076] The dry powder fire extinguishing agent is prepared according to the method described in Example 2, wherein the silicone oil is mixed with azotetrazolium sodium salt, lithium nitrate, ammonium metaphosphate and activated clay evenly and heated to 50°C with talcum powder Add together with white carbon black, continue stirring and mixing for 10 minutes to discharge, and finally vacuum dry, sieve to remove particles with a size larger than 0.25 mm, inspect, and pack to obtain the ABC dry powder fire extinguishing agent of this embodiment.

Abstract

The invention relates to an ABC dry powder extinguishing agent. An extinguishing base material of the extinguishing agent is formed by nitrate (perchlorate) of <+2> valent or <+1> valent metal ions, or is formed by a mixture of the nitrate (perchlorate) with an imidazole compound; and the ABC dry powder extinguishing agent can be widely applied to extinguishing various combustible solids, liquid and gas fire disasters and can also be used for putting out electric fire disasters. Compared with an existing commonly-used ammonium phosphate ABC dry powder extinguishing agent, the ABC dry powder extinguishing agent has higher 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. Specifically, the present invention relates to a dry powder fire extinguishing agent that can be used to extinguish various combustible solid, liquid, gas fires and electrical fires. The 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 existing ABC dry powder fire extinguishing agent is mainly based on the formula of ammonium phosphate and potassium sulfate as the fire extinguishing base material. After the ammonium phosphate ABC dry powder fire extinguishing agent is sprayed into the fire site, it can form a flame-retarda...
