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] Take by weighing 10 grams of perfluorobetaine, 30 grams of fluorinated alkyl betaines, 10 grams of urea, 50 grams of α-olefin sulfonate sodium, 100 grams of sodium lauryl sulfate, 100 grams of alkyl glycosides (1412), Dissolve in 700 grams of tap water, stir at high speed to make it evenly mixed to get foam fire extinguishing agent.

[0013] The foam fire extinguishing agent was formulated into a tap water solution with a mass fraction of 3%, 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] Take by weighing 30 grams of perfluorobetaine, 80 grams of fluorinated alkyl betaines, 50 grams of urea, 150 grams of α-olefin sulfonate sodium, 150 grams of sodium lauryl sulfate, 160 grams of alkyl glycosides (1412), Dissolve in 380 grams of tap water, stir at high speed to make it evenly mixed to get foam fire extinguishing agent.

[0016] The foam fire extinguishing agent was formulated into a tap water solution with a mass fraction of 3%, 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.

Embodiment 3

[0018] Take by weighing 20 grams of perfluorobetaine, 50 grams of fluorinated alkyl betaines, 30 grams of urea, 120 grams of α-olefin sulfonate sodium, 120 grams of sodium lauryl sulfate, 120 grams of alkyl glycosides (1412), Dissolve in 540 grams of tap water, stir at a high speed to make it evenly mixed to obtain a foam fire extinguishing agent.

[0019] The foam fire extinguishing agent was formulated into a tap water solution with a mass fraction of 3%, filled into MSJ950 water-based fire extinguisher, and put out 8B 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 immediately, and the fire is controlled within 4 seconds, has only a small flame within 8 seconds, and is completely extinguished within 10 seconds.

Abstract

The invention discloses a foam extinguishing agent. The foam extinguishing agent is composed of, by mass, 1-3% of perfluorinated betaine, 3-8% of fluorinated alkyl betaine, 1-5% of urea, 5-15% of Sodium alpha olefin sulfonate, 10-15% of lauryl sodium sulfate, 10-16% of alkyl polyglucoside (1412) and the balance water. The invention further discloses application of the foam extinguishing agent. The thickness and the stability of films generated by the foam extinguishing agent are high, 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...
