Problems solved by technology

The temperature reduction depends on the evaporation of water to absorb heat, and the cooling effect is not good, making the fire extinguishing speed slower
[0003] At the same time, when the fire extinguishing agent of the prior art is at minus 50 degrees Celsius, the fire extinguishing agent is solidified, so that it cannot be used in a low temperature environment, and its adaptability is weak

Embodiment 1

[0012] Weigh 20 grams of perfluorooctyl quaternary ammonium iodide, 20 grams of fluorinated alkyl betaine, 50 grams of decayl betaine, 3 grams of xanthan gum, 50 grams of lauryl imidazoline betaine, and 400 grams of triethanolamine. Phosphate ester, dissolved in 457 grams of water, high-speed shearing and stirring to make it evenly mixed to obtain ultra-low temperature foam fire extinguishing agent, minus 50 ℃ does not freeze.

[0013] The foam fire extinguishing agent is formulated into an aqueous solution with a mass fraction of 6%, which is filled into the MSJ950 water-based fire extinguisher to extinguish 13B gasoline fires. The fire extinguishing agent is sprayed to the oil surface through the fire extinguisher, the dense smoke immediately turns into white water vapor, the fire is controlled within 6 seconds, and there is only a small flame within 8 seconds, and it is completely extinguished within 12 seconds.

Embodiment 2

[0015] Weigh 50 grams of perfluorooctyl quaternary ammonium iodide, 50 grams of fluorinated alkyl betaine, 100 grams of decayl betaine, 8 grams of xanthan gum, 100 grams of lauryl imidazoline betaine, and 600 grams of triethanolamine. Phosphate ester, dissolved in 92 grams of water, high-speed shearing and stirring to make it evenly mixed to obtain ultra-low temperature foam fire extinguishing agent, minus 50 ℃ does not freeze.

[0016] The foam fire extinguishing agent is formulated into an aqueous solution with a mass fraction of 6%, which is filled into the MSJ950 water-based fire extinguisher to extinguish 13B gasoline fires. The fire extinguishing agent is sprayed to the oil surface through the fire extinguisher, the dense smoke immediately turns into white water vapor, the fire is controlled within 6 seconds, and there is only a small flame within 8 seconds, and it is completely extinguished within 12 seconds.

Embodiment 3

[0018] Weigh 35 grams of perfluorooctyl quaternary ammonium iodide, 35 grams of fluorinated alkyl betaine, 75 grams of decayl betaine, 6 grams of xanthan gum, 75 grams of lauryl imidazoline betaine, and 500 grams of triethanolamine. Phosphate ester, dissolved in 274 grams of water, high-speed shearing and stirring to make it evenly mixed to obtain ultra-low temperature foam fire extinguishing agent, minus 50 ℃ does not freeze.

[0019] The foam fire extinguishing agent is formulated into an aqueous solution with a mass fraction of 6%, which is filled into the MSJ950 water-based fire extinguisher to extinguish 13B gasoline fires. The fire extinguishing agent is sprayed to the oil surface through the fire extinguisher, the dense smoke immediately turns into white water vapor, the fire is controlled within 6 seconds, and there is only a small flame within 8 seconds, and it is completely extinguished within 12 seconds.

Abstract

A fire extinguishing agent for ultralow temperature is disclosed. The fire extinguishing agent comprises following components by mass: 2-5% of perfluoroalkylsulfonyl quaternary ammonium iodide, 2-5% of fluoroalkylbetaine, 5-10% of decylalkylbetaine, 0.3-0.8% of xanthan gum, 5-10% of laurylimidazoline betaine and 40-60% of triethanolamine phosphate, with the balance being water. An application of the fire extinguishing agent for ultralow temperature is further disclosed. The fire extinguishing agent can rapidly extinguish fire and is suitable for ultralow-temperature environments.

Description

Technical field [0001] The invention relates to an ultra-low temperature fire extinguishing agent. Background technique [0002] In the prior art, due to the high flame combustion temperature, the temperature of the fire field usually reaches above 1100°C, so that when the foam extinguishing agent is sprayed on the ignition point, the extinguishing agent is instantly evaporated, thereby failing to achieve the covering and isolating effect and affecting the fire extinguishing. Therefore, the foam produced by the fire extinguishing agent can only exist stably when the ignition temperature is lowered, and the fire can be quickly extinguished. The temperature reduction relies on water evaporation to absorb heat, and the cooling effect is not good, which makes the fire extinguishing speed slow. [0003] At the same time, when the fire extinguishing agent of the prior art is at minus 50 degrees Celsius, the extinguishing agent is solidified, making it unsuitable for low-temperature envi...
