Problems solved by technology

[0004] Aqueous film-forming foam fire extinguishing agents were successfully developed in the 1980s and are currently widely used. However, this type of fire extinguishing agent is limited by low temperature use, and has poor permeability in extinguishing Class A fires, and the anti-resurgence time is short.
[0005] Water-based fire extinguishing agent is another

Abstract

The invention provides an extinguishing agent, which comprises a fluorine-containing surfactant, an emulsifier or aliphatic alcohol, a fire retardant, an anion surfactant, a thickener, urea, water and an optional antifreezing agent. The extinguishing agent has good fire-extinguishing performance and after-combustion resistant performance, and has the performance of extinguishing A fire, B fire, soluble liquid fuel fire and electric appliance fire. The antifreezing agent with different proportions prepared by a pre-mixed solution can be directly used at a lower temperature of between 5 DEG C below zero and 40 DEG C below zero; the extinguishing agent particularly can not perform after-combustion within a few hours after the fire is extinguished; and foams can last for 10 hours.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a water-based solvent-resistant and cold-resistant fire extinguishing agent. technical background [0002] In recent years, fire extinguishing agents at home and abroad have gradually become more environmentally friendly, multi-functional, and high-efficiency. At present, most of the products produced by fire extinguishing agent manufacturers in my country are ABC dry powder, BC dry powder, aqueous film-forming foam fire extinguishing agent and water-based fire extinguishing agent. They have strong fire extinguishing professional performance, but they cannot extinguish several types and special fires at the same time, and are affected by the use temperature. limits. [0003] Dry powder fire extinguishing agent has obvious limitations. It can only be used to fill fire extinguishers. It is powerless against electrical fires and large-scale fires, and it does not have the ability to res...
