Abstract

The invention belongs to the technical field of preparation of fire extinguishing agents, and particularly relates to a preparation method and application of a compound foam fire extinguishing agent.The preparation method of the compound foam fire extinguishing agent comprises the following steps that firstly, deionized water, imidazoline, a fluorocarbon surfactant, foaming agents and stabilizersare added into a stirring tank, and are stirred and reacted under the normal temperature; and the pH value of the reaction liquid is adjusted, and the compound foam fire extinguishing agent is obtained after natural stewing treatment. The prepared compound foam fire extinguishing agent is long in burning resisting time and good in foam heat stability and burning resisting performance; the freezing point is low, and the compound foam fire extinguishing agent is suitable for being used at cold areas in North; and in addition, the compound foam fire extinguishing agent is mixed with sea water tobe used, the good fire extinguishing effect is shown, and the ideal sea water resisting performance is achieved. The operation process is simple, the conditions are easy to control, cost is low, andthe compound foam fire extinguishing agent is suitable for large-scale industrial production and can be widely used for extinguishing B-type fire disasters.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing agent preparation, and in particular relates to a preparation method and application of a synthetic foam fire extinguishing agent. Background technique [0002] Synthetic foam (S) fire extinguishing agent is a foam fire extinguishing agent made of a mixture of surfactants and stabilizers. The fire extinguishing mechanism of the synthetic foam fire extinguishing agent is that the foam produced by the fire extinguishing agent dilutes the oxygen content in the burning area when fighting a fire, and closes the surface of the burning object to isolate it from the air, so as to achieve the purpose of fire extinguishing. Due to the action of the synthetic foam fire extinguishing agent surfactant, the foam produced has the advantages of low surface tension and strong oleophobicity, and can be used in combination with dry powder to extinguish the fire of the oil tank by spraying under the liquid...
