Problems solved by technology

[0003] In the prior art, the thickness and stability of the film produced by the foam fire extinguishing agent are not strong, and it will decompose at 300°C-400°C, and the covering ability cannot be achieved. Moreover, the cooling speed is too slow, which makes the fire extinguishing speed slow and the fire extinguishing effect is low. Poor, easy to reignite

Embodiment 1

[0012] Weigh 6.5 grams of perfluorooctyl quaternary ammonium iodide, 7.5 grams of fluorinated alkyl betaine, 2 grams of urea, 81 grams of cocamidopropyl betaine, 78 grams of n-octanol ether sulfonate, 125 grams of alkanol Glycoside, 55 grams of ethylene glycol, and 1.5 grams of xanthan gum are dissolved in 613.5 grams of tap water, stirred at a high speed, and mixed evenly to obtain a foam fire extinguishing agent.

[0013] The foam fire extinguishing agent was formulated into a tap water solution with a mass fraction of 6%, filled into a MSJ950 water-based fire extinguisher, and extinguished a 13B gasoline fire. The fire extinguishing agent is sprayed onto the oil surface by the fire extinguisher, and the dense smoke turns into white water vapor at once, and the fire is controlled within 6 seconds, has only a small flame within 8 seconds, and is completely extinguished within 14 seconds.

Embodiment 2

[0015] Weigh 38.5 grams of perfluorooctyl quaternary ammonium iodide, 13.5 grams of fluorinated alkyl betaine, 9 grams of urea, 105 grams of cocamidopropyl betaine, 102 grams of n-octanol ether sulfonate, 188 grams of alkane Glycosides, 86 grams of ethylene glycol, and 3.5 grams of xanthan gum are dissolved in 454.5 grams of tap water, stirred at a high speed, and mixed evenly to obtain a foam fire extinguishing agent.

[0016] The foam fire extinguishing agent was formulated into a tap water solution with a mass fraction of 6%, filled into a MSJ950 water-based fire extinguisher, and extinguished a 13B gasoline fire. The fire extinguishing agent is sprayed onto the oil surface by the fire extinguisher, and the dense smoke turns into white water vapor at once, and the fire is controlled within 6 seconds, has only a small flame within 8 seconds, and is completely extinguished within 14 seconds.

Embodiment 3

[0018] Weigh 30 grams of perfluorooctyl quaternary ammonium iodide, 10 grams of fluorinated alkyl betaine, 7 grams of urea, 95 grams of cocamidopropyl betaine, 92 grams of n-octanol ether sulfonate, 168 grams of alkane Glycoside, 66 grams of ethylene glycol, 2.5 grams of xanthan gum, dissolved in 529.5 grams of tap water, stirred at a high speed, and mixed evenly to obtain foam fire extinguishing agent.

[0019] The foam fire extinguishing agent was formulated into a tap water solution with a mass fraction of 6%, filled into a MSJ950 water-based fire extinguisher, and extinguished a 13B gasoline fire. The fire extinguishing agent is sprayed onto the oil surface by the fire extinguisher, and the thick smoke turns into white water vapor immediately, and the fire is controlled within 5 seconds, has only a small flame within 9 seconds, and is completely extinguished within 13 seconds.

Abstract

The invention discloses a foam extinguishing agent. The foam extinguishing agent is composed, by mass, 0.65% to 3.85% of trimethyl-1-propanaminium iodide, 0.75% to 1.35% of fluorinated alkyl betaine, 0.2% to 0.9% of urea, 8.1% to 10.5% of cocamidopropyl betaine, 7.8% to 10.2% of n-caprylic alcohol ether sulfonate, 12.5% to 18.8% of alkyl glycoside (0810), 5.5% to 8.6% of ethylene glycol, 0.15% to 0.35% of xanthan gum and the balanced water. The invention further discloses application of the foam extinguishing agent. A film generated by the foam extinguishing agent is higher in thickness and stability, the extinguishing speed is high, and the extinguishing effect is good.

Description

technical field [0001] The invention relates to a foam fire extinguishing agent. Background technique [0002] Foam fire extinguishing agent can be divided into protein foam fire extinguishing agent and synthetic foam fire extinguishing agent according to the matrix of synthetic foam. Protein foam fire extinguishing agents mainly include ordinary protein foam fire extinguishing agents, fluoroprotein foam fire extinguishing agents, film-forming fluoroprotein foam fire extinguishing agents, anti-solvent and film-forming protein anti-solvent foam fire extinguishing agents; synthetic foam fire extinguishing agents mainly include high-expansion foam fire extinguishing agents , High, medium and low power general-purpose fire extinguishing foam, water film-forming foam fire extinguishing agent, water-resistant water film-forming fire extinguishing agent, Class A fire foam. [0003] In the prior art, the thickness and stability of the film produced by the foam fire extinguishing ag...
