Definitions
- the present invention relates to a water-based fire extinguishing agent, and more particularly, by composing a fire extinguishing agent including a non-electrolyte material, a cryoprotectant, a silicone surfactant and water, ) relates to water-based fire extinguishing agents that can also be applied.
- fires are classified into Class A fires, Class B fires, and Class C fires.
- Class A fires are fires caused by combustible materials such as wood or paper, and it is useful to extinguish them by cooling them to below the ignition point using a water-based fire extinguisher. It is useful to extinguish a fire using CO 2 ), Halon and Foam fire extinguishers, and the most effective way to extinguish a Class C fire is by blocking oxygen by carbon dioxide (CO 2 ) as a fire caused by electricity. useful.
- CO 2 carbon dioxide
- A, B, and C fires are used a powder fire extinguisher (ABC powder) and a gas fire extinguisher.
- ABS powder powder fire extinguisher
- gas fire extinguishers have a problem of causing environmental pollution such as suffocation or destruction of the ozone layer after use, depending on the composition of the gas, so the use is gradually decreasing.
- Water has a very high specific heat (1kcal/kg ⁇ °C) and absorbs a lot of heat. Due to its large latent heat of evaporation (539kcal/kg), it cools combustibles by taking a large amount of heat from the surroundings during vaporization, and the vaporization expansion rate (1,650 times) is high. It is useful as a fire extinguishing agent because it has a large vapor covering the combustion surface and has a suffocating fire extinguishing effect. However, such water is effective for Class A fires, but has the disadvantage of being vulnerable to Class B and C fires.
- Korean Patent Registration No. 10-1300870 proposes a water-based fire extinguishing agent containing water, alkyl acid phosphate, glycol, hydrocarbon-based surfactant, ammonia water, etc. made it possible
- these pre-registered patents still had the disadvantage of being difficult to apply to class C fires.
- Korean Patent Registration No. 10-2043750 also proposes an immersion fire extinguishing agent composition containing metal carbonate, freezing point depressant, fluorine-based surfactant, urea, water, etc., so that it can be applied to class A as well as class B fire .
- these pre-registered patents still had the disadvantage of being difficult to apply to class C fires.
- Another object of the present invention is to provide an environmentally friendly water-based fire extinguishing agent that is harmless to the human body and the environment, and does not have secondary pollution.
- the water-based fire extinguishing agent of the present invention for achieving the above object includes a non-electrolyte material, a cryoprotectant, a silicone surfactant or silicone oil, and water, and is characterized in that it is adaptable to electric fires.
- the fire extinguishing agent is characterized in that it comprises 5 to 15 wt% of the non-electrolyte material, 25 to 40 wt% of a cryoprotectant, 1 to 10 wt% of a silicone surfactant or silicone oil, and the remainder of water.
- the non-electrolyte material may be one or two or more selected from glucose, ethanol, acetone, glycerin, starch, cellulose, urea, sugar, and protein.
- the cryoprotectant may be a mixture of ethylene glycol, propylene glycol and dipropylene glycol in a weight ratio of 1 to 3:2 to 6:1.
