Problems solved by technology

Because the water stays on the branches and leaves for a very short time during the fire extinguishing process, the fire extinguishing efficiency of this fire extinguishing agent is low, so that the mountain fire that seems to be extinguished by water often suddenly revives

Embodiment 1

[0022] The components of this example mountain fire extinguishing agent include:

[0023]

[0024] The production method of this example mountain fire extinguishing agent comprises the following steps:

[0025] (1), the ammonium polyphosphate of described weight, urea are fully dissolved in the water of described weight to form mixed solution;

[0026] (2), adding the N,N-dimethyl-3-perfluorooctylsulfonamidopropylammonium iodine salt, vinyl alcohol, sodium bicarbonate, sodium polyacrylate, ethylene glycol of the weight successively, stirring Uniform;

[0027] (3), add the silicon dioxide of described weight, stir evenly.

Embodiment 2

[0029] The components of this example mountain fire extinguishing agent include:

[0030]

[0031] The production method of this example mountain fire extinguishing agent comprises the following steps:

[0032] Step (1) is with embodiment 1;

[0033] (2), add the N,N-dimethyl-3-perfluorooctylsulfonamidopropylammonium iodine salt, vinyl alcohol, sodium bicarbonate, sodium polyacrylate, propylene glycol of the weight in sequence, and stir evenly;

[0034] (3), add silicon dioxide and mica powder of described weight, stir evenly.

[0035] The mountain fire fire extinguishing agent of the above two embodiments is diluted with water at a ratio of 1:10 when used, and then poured into a fine water mist fire extinguisher to implement spraying fire extinguishing. The experimental results of the trial production show that its fire extinguishing efficiency reaches GB15308-2006 standard water fire extinguishing efficiency or the fire extinguishing efficiency of foam fire extinguishin...

Abstract

The invention discloses an extinguishing agent for forest fire. The extinguishing agent comprises the following components: 4 to 20% of sodium bicarbonate, 5 to 20% of silicon dioxide, 4 to 40% of ammonium polyphosphate, 4 to 20% of urea, 0.5 to 10% of N-N-dimethyl-3-perfluorooctylsulfonylpropyl-aminium iodide, 1 to 5% of vinyl alcohol, 1 to 5% of sodium polyacrylate, 0.5 to 5% of glycol, and 40 to 80% of water. The production method comprises the following steps: (1) dissolving ammonium polyphosphate, and urea into water; (2) adding N-N-dimethyl-3-perfluorooctylsulfonylpropyl-aminium iodide, vinyl alcohol, sodium bicarbonate, sodium polyacrylate and glycol, and uniformly agitating; and (3) adding silicon dioxide, and uniformly agitating. With the adoption of the agent, the oxygen isolating and cooling capacity of water is improved, the water consumption is decreased, the covering effect is improved with solid particles, and the phenomenon of backfire can be effectively inhibited; and the agent is outstanding in performance, convenient to carry, and beneficial for wide popularization.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a fire extinguishing agent for mountain fires. Background technique [0002] Combustion is a violent chemical reaction that emits light and heat. Combustion of substances involves three necessary conditions, one is combustibles, the other is oxygen, and the third is to reach the minimum temperature of combustion. Accordingly, all fire extinguishing measures are designed around destroying the already formed combustion conditions. Among them, the fire extinguishing agent is one of the key material conditions that cannot be avoided in all extinguishing designs. Commonly used fire extinguishing agents are dry powder fire extinguishing agents, such as sodium bicarbonate dry powder, sodium chloride dry powder, potassium chloride dry powder, ammonium phosphate dry powder; gas fire extinguishing agents, such as carbon dioxide, inert gas; foam fire extinguishing agents, such as protein foam...
