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 respectively 30 grams of perfluorooctyl quaternary ammonium iodide, 30 grams of ethylene glycol, 30 grams of urea, 50 grams of sodium lauryl alcohol polyoxyethylene ether sulfate, 50 grams of sodium dodecylbenzenesulfonate, 100 One gram of nonylphenol polyoxyethylene ether is dissolved in 710 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 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 40 grams of perfluorooctyl quaternary ammonium iodide, 35 grams of ethylene glycol, 40 grams of urea, 50 grams of sodium lauryl alcohol polyoxyethylene ether sulfate, 65 grams of sodium dodecylbenzenesulfonate, 150 grams One gram of nonylphenol polyoxyethylene ether is dissolved in 620 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 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 3

[0018] Weigh 50 grams of perfluorooctyl quaternary ammonium iodide, 50 grams of ethylene glycol, 50 grams of urea, 80 grams of sodium lauryl alcohol polyoxyethylene ether sulfate, 80 grams of sodium dodecylbenzenesulfonate, 300 grams One gram of nonylphenol polyoxyethylene ether is dissolved in 390 grams of tap water, stirred at a high speed, and mixed evenly 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 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 which comprises the following components in percentage by mass: 3-5 percent of trimethyl-1-propanaminium iodide, 3-5 percent of ethanediol, 3-5 percent of urea, 5-8 percent of AES-2EO-70, 5-8 percent of sodium dodecyl benzene sulfonate, 10-30 percent of nonylphenol polyoxyethylene ether and the balance of water. The invention further discloses application of the foam extinguishing agent. A film formed by the foam extinguishing agent provided by the invention is relatively high in thickness and stability, the extinguishing speed is high and the extinguishing effect is better.

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...
