Embodiment 1

[0065] Put water in a container equipped with a stirrer, slowly add three kinds of inorganic substances (potassium carbonate, magnesium carbonate, and calcium chloride) as fire extinguishing components, and stir until completely dissolved, and then further add surfactant (mixture of 3) , antifreeze and preservative, and stir (to make a stirred solution) until it becomes transparent.

[0066] Then, after adding fatty acid methyl ester solution to the stirring solution and stirring, finally adding an appropriate amount of citric acid to adjust the pH to neutral (pH about 7.0), and then stopping the stirring for 24 hours to stabilize. At this time, the fatty acid methyl ester solution used was a 20% by weight aqueous solution in which water-soluble fatty acid metal salt (sodium stearate) fine particles (average particle size about 5 μm) were dissolved in water. The following [Table 1] shows the specific components and contents of the fire extinguishing agent according to this emb...

Embodiment 2

[0068] The implementation is the same as in Example 1, except that fatty acid methyl esters use insoluble fatty acid methyl esters. Specifically, except that a 20% by weight dispersion of insoluble fatty acid metal salt (calcium stearate) particles (average particle size about 5 μm) was stirred and dispersed in water as the fatty acid methyl ester solution, the same method as in Example 1 same. The specific components and contents of the fire extinguishing agent according to this embodiment are shown in [Table 1] below.

Embodiment 3

[0070] The implementation is the same as in Example 2, and a dispersant is further added to the fatty acid methyl ester solution. Specifically, insoluble fatty acid metal salt (calcium stearate) was stirred and dispersed in water as fatty acid methyl ester. The above-mentioned embodiment 2 is the same. At this time, the dispersant was a commercially available product, and a product (BYK-154) of BYK, Germany was used. The specific components and contents of the fire extinguishing agent according to this embodiment are shown in [Table 1] below.

Abstract

The present invention relates to a loaded stream fire extinguishing agent having excellent fire extinguishing performance and a method for producing the same. The present invention provides a loaded stream fire extinguishing agent comprising: water; a fire extinguishing component selected from an inorganic material; a surfactant; a cryoprotective agent; a corrosion inhibitor; and a fatty acid ester salt, and a method for producing the same. The loaded stream fire extinguishing agent according to the present invention is harmless to the human body, is eco-friendly, has improved corrosion resistance and storage stability, etc. and has excellent fire extinguishing performance.

Description

technical field [0001] The present invention relates to an enhanced liquid fire extinguishing agent with excellent fire extinguishing function and a manufacturing method thereof, and more specifically, to an enhanced liquid fire extinguishing agent having excellent fire extinguishing performance and improved corrosion resistance and storage stability and a manufacturing method thereof. Background technique [0002] Water is most commonly used as a fire extinguishing agent because it is cheap, does not deteriorate and is not harmful to humans. Moreover, water has a high specific heat and can absorb more heat, and has high latent heat of evaporation, so that it can absorb a large amount of heat from the surroundings and cool combustibles when a fire occurs, and the fire expansion rate is large, and the water vapor covers the burning surface and suffocates the fire extinguishing effect. Also strong. [0003] Recently, an enhanced liquid fire extinguishing agent has been develo...
