Abstract

The invention provides an aqueous film-forming foam extinguishing agent special for a fire extinguishing bullet and a throwing type fire extinguisher. The aqueous film-forming foam extinguishing agent has the advantages of being small in additive amount, rapid in fire extinguishing, good in recrudescence resisting effect, environmentally friendly, efficient and the like. The aqueous film-forming foam extinguishing agent comprises, by weight, 8 percent to 12 percent of main foaming agents, 8 percent to 20 percent of auxiliary foaming agents, two percent to 10 percent of antifreeze agents, 12 percent to 22 percent of cosolvents, 0.1 percent to one percent of stabilizers, 8 percent to 20 percent of fire retardants, two percent to five percent of burning-resistance agents and the balance water. The main foaming agents are selected from F1157N, F1203 and F1460, the auxiliary foaming agents are selected from lauryl sodium sulfate, ammonium lauryl sulfate, alkyl glycoside, dodecyl dimethyl betaine and cocamidopropyl betaine. The antifreeze agents are selected from ethylene glycol, glycerol and the like. The cosolvents are selected from dodecanol, n-butyl alcohol and diethylene glycol diethyl ether. The stabilizing agents are selected from xanthan gum, Arabic gum, guar gum and sodium alginate tech grade. The fire retardants are selected from ammonium polyphosphate and ammonium dihydrogen phosphate.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to an aqueous film-forming foam fire extinguishing agent. Background technique [0002] Most of the casualties in the fire were caused by too late escape, especially those vulnerable groups such as the elderly, children and people with limited mobility. Then we need to consider whether we can use the fire extinguisher correctly in an emergency, whether we know how to use it and whether we can move the fire extinguisher near the fire source. In view of this idea, a series of fire extinguishing devices such as fire extinguishing bombs and throwing fire extinguishers have been developed on the market. Throwing fire extinguishers (fire extinguishing bombs) similar to the size of mineral water bottles are used to extinguish initial fires. This type of fire extinguisher is easy to use, just put it into the fire source to extinguish the fire. At present, there is no uniform standard for the ...
