Problems solved by technology

However, the above-mentioned fire extinguishing agents have no fire extinguishing effect on the initial fire of electrical appliances. When traditional fire extinguishing agents are used to extinguish a fire, electrical short circuits and leakage will cause secondary fires or other accidental casualties, which will bring safety hazards to personnel rescue and evacuation.
[0003] Chinese patent CN201710350557.1 discloses a compound synergistic A, B, E water-based fire extinguishing agent, which is composed of hydrocarbon surfactants, ammonium polyphosphate, coconut oil alkyl betaine, cationic hydroxyethyl cellulose It is made of polymer, dodecyl imidazoline, fluorosurfactant and deionized water. While extinguishing class A and B fires, it can also extinguish charged class E fires below 36KV, but the fire extinguishing effect of this fire extinguishing agent is not obvious enough. There are disadvantages such as long fire extinguishing time

Abstract

The invention discloses a water-system fire extinguishing agent for a storage battery fire disaster. The water-system fire extinguishing agent is prepared from the following raw materials in parts byweight: 130-160 parts of a hydrocarbon surfactant, 32-42 parts of a flame retardant, 100-125 parts of dodecyl dimethyl betaine, 12-20 parts of a catching agent, 80-95 parts of a preservative, 100-120parts of a betaine type fluorine-containing surfactant and 500-535 parts of deionized water. The water-system fire extinguishing agent for the storage battery fire disaster disclosed by the inventionovercomes the problem that secondary fire or other fortuitous casualties are caused by an electrical short circuit and electric leakage as a conventional water-system fire extinguishing agent cannot extinguish E-type fire disasters as well as the conventional water-system fire extinguishing agent extinguishes fire; and moreover, the fire extinguishing agent is shorter in fire extinguishing time and is better in fire extinguishing effect. The invention further discloses a preparation method for the water-system fire extinguishing agent for the storage battery fire disaster.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a water-based fire extinguishing agent for accumulator fires and a preparation method thereof. Background technique [0002] The traditional compound synergistic type A and B water-based fire extinguishing agents quickly extinguish solid substances such as wood, cotton, Class A fires of wool, hemp, paper and their products, and Class B fires of liquid or meltable solids, such as gasoline, kerosene, diesel oil, crude oil, methanol, ethanol, asphalt, paraffin, etc. The functional components form a high-temperature-resistant, heat-insulating, and flame-retardant covering layer on the surface of combustibles to play an anti-reburning effect. However, the above-mentioned fire extinguishing agents have no fire extinguishing effect on the initial fire of electrical appliances. When traditional fire extinguishing agents extinguish a fire, electrical short circuits and ...
