Abstract

The invention relates to a cold-resistant aqueous film forming foam extinguishing agent. The cold-resistant aqueous film forming foam extinguishing agent is prepared from the following components in percentage by mass: 12 to 30% of a composite hydrocarbon surfactant, 2 to 5% of a fluorocarbon surfactant, 0.1 to 1% of a foam stabilizer, 20 to 50% of an antifreeze agent, 3 to 5% of solubilizer, and the balance of water, wherein the composite hydrocarbon surfactant is a composition of an ampholytic surfactant and a nonionic surfactant. The cold-resistant aqueous film forming foam extinguishing agent is applicable to extinguishing of fire caused by hydrocarbon substances, can be normally used at the environmental temperature of -25 DEG C, and in particularly suitable for the super cold area; in addition, the hydrocarbon surfactant at grade of daily necessities, and the fluorocarbon surfactant free of PFOS (Perfluorooctane sulfonates) are adopted, so that the cold-resistant aqueous film forming foam extinguishing agent is high in degrading performance, can be quickly and safely degraded, and is free of environmental pollution.

Description

technical field [0001] The invention relates to a foam fire extinguishing agent, in particular to an 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 non-rescue water-soluble flammable and flammable liquids. It mainly generates a condensed foam floating layer on the surface of the liquid to suffocate and cool. [0003] Aqueous film-forming foam fire extinguishing agent (AFFF for short) is a foam fire extinguishing agent that is based...
