Abstract

The invention relates to a cold-resistant anti-fusible aqueous film forming foam extinguishing agent. The cold-resistant anti-fusible aqueous film forming foam extinguishing agent consists of the following gradients in percentage by mass: 12-30 percent of a composite hydrocarbon surfactant, 4-6 percent of a compounded fluorocarbon surfactant, 0.5-1 percent of a foam stabilizer, 20-50 percent of an antifreeze agent, 3-5 percent of a solubilizer and the balance water, wherein the composite hydrocarbon surfactant is a composition of an ampholytic surfactant and a nonionic surfactant. The cold-resistant anti-fusible aqueous film forming foam extinguishing agent disclosed by the invention is mainly applied to prevention and extinguishing of fire caused by hydrocarbon substances and polar solvents (water-soluble substances), can be normally used at an environment temperature of -25 DEG C and is especially applicable to storage and use in extremely-cold regions. Besides, by adopting a daily-necessity-level hydrocarbon surfactant and a fluorocarbon surfactant which is free of PFOS (Perfluorooctane Sulfonates), the cold-resistant anti-fusible aqueous film forming foam extinguishing agent disclosed by the invention is good in degradation property, quick and safe in degradation and free of environmental pollution.

Description

technical field [0001] The invention relates to a foam fire extinguishing agent, in particular to a solvent-resistant aqueous film-forming foam fire extinguishing agent which can be used at a low temperature of -25°C, and belongs to the technical field of fire-fighting consumables. Background technique [0002] Fire extinguishing agents are generally divided into foam fire extinguishing agents, dry powder fire extinguishing agents, etc., and foam fire extinguishing agents can be divided into aqueous film-forming foam fire extinguishing agents, chemical foam fire extinguishing agents and air foam fire extinguishing agents. Foam fire extinguishing agent is an effective fire extinguishing agent for extinguishing flammable and combustible liquids. It mainly generates a condensed foam floating layer on the surface of the liquid to suffocate and cool. [0003] Alcohol-resistant aqueous film-forming foam fire extinguishing agent (AFFF / AR) is widely used to extinguish various types ...
