Abstract

The invention discloses a water-base extinguishing agent, comprising hydrocarbon surfactant, stabilizing / coupling agent, chelating agent, spreading anti-burning agent, antifreeze agent, emulsifier, tackifier and water. According to the invention, inert gases are used for emission, and foam is generated by emulsification of solution and heating to cover the fire, so that the water-base extinguishing agent is most effective to put out fire of oils. The main added ingredients have no toxicity and no pollution, so that the water-base extinguishing agent is a environment-friendly extinguishing agent. The water-base extinguishing agent has the advantages of low price of the additives, easy obtainment of the additives and simple production process, and is suitable for large-scale application andextension.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a water-based emulsified fire extinguishing agent which generates foam when heated. Background technique [0002] In recent years, domestic and foreign fire protection markets have gradually become more environmentally friendly, high-efficiency, and adaptable to fire extinguishing agents. At present, most of the products of fire extinguishing agent manufacturers in my country are ABC dry powder and BC dry powder, but their application is highly specialized, and they can only be used to fill fire extinguishers to extinguish initial fires. It also causes certain harm to the evacuation of personnel. Due to the extremely low surface tension, the fire extinguishing agent added with fluorocarbon surfactant can spread on the surface of the liquid, which plays a good role in oxygen barrier and suffocation, and reduces radiation and evaporation. However, the core technology of fluorocarbon s...
