Abstract

The invention relates to a cold-resistant environment-friendly water fire extinguishing agent. The cold-resistant environment-friendly water fire extinguishing agent contains no PFOS fluorine hydrocarbon surface active agent, is added with an active fire extinguishing component, is capable of solving the problems of synergic effects of all the components and cold-resistant environmental protection, is capable of greatly promoting the fire extinguishing efficiency, cold resistance and environmental protection level, meets the standard requirement of GB / T17835-2008 Water Fire Extinguishing Agent, has a smoke abatement function and is nontoxic. The cold-resistant environment-friendly water fire extinguishing agent is suitable for electrified fire extinguishing for various fire disasters, such as, solid, oily and water-soluble fluid fuels, is suitable for fire extinguishing with fresh water and seawater at low temperature below -40 DEG C, and can be filled into the present common fire extinguishing devices and pipeline fire extinguishing systems. The cold-resistant environment-friendly water fire extinguishing agent is simple in production process, low in equipment investment, low in production cost and suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of water-based fire extinguishing agent processing, in particular to a production method of a cold-resistant and environment-friendly water-based fire extinguishing agent. Background technique [0002] Water-based fire extinguishing agents are widely used due to their wide range of fire extinguishing after solving the problem of high fire extinguishing efficiency. In recent years, as the global climate El Niño phenomenon has become more serious, resulting in frequent occurrence of extreme weather, it is necessary to develop water-based fire extinguishing agents with high cold resistance, especially resistance above -25°C. However, high cold-resistant water-based fire extinguishing agents need to increase the amount of antifreeze, which affects the toxicity of water-based fire extinguishing agents. Therefore, we are committed to developing new formulations of water-based fire extinguishing agents with high efficiency,...
