Abstract

The invention relates to an A popular type multifunctional foam fire extinguishing agent, which mainly consists of a protecting colloid consisting of microlite chitin, sesbania gum and hydroxyethyl cellulose; vesicant consisting of polyoxyethylene fatty alcohol sodium sulfate, alkyl polysaccharide glycoside, salt free imidazoline and hydrocarbon surface active agent; burn resisting film forming agent consisting of silicone surface active agent, fluorocarbon surface active agent and fluorocarbon silicone surface active agent; flame retardant comprising one or a plurality of condensed phosphate, borax and boric acid; addition agent consisting of short chain alcohol and ether and metal salt; osmotic agent which is high efficient osmotic agent BS or rapid osmotic agent T; and water margin. Being applicable for the prior various foam fire extinguishing devices, the fire extinguishing agent not only can put out the polar and non-polar A, B fires, but also can effectively put out the polar and non-polar mixture fires with any ratio with little fire extinguishing agent and water. The invention has the advantages of simple processing technique, no special facility, low cost and no environmental pollution in production and usage.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a Class A general-purpose multipurpose foam fire extinguishing agent, which belongs to the technical field of fire extinguishing agent preparation. Background technique [0002] At present, environmental pollution is increasing day by day, the atmospheric ozone layer has been severely damaged, and the energy crisis has posed a strong challenge to mankind. How to protect the earth environment on which human beings depend has become the most extensive and most urgent issue in today's society. In Europe, ethanol gasoline and methanol gasoline have been used to save the consumption of crude oil, and our country also attaches great importance to it and has taken active countermeasures. Fires occur frequently, and the amount of fire extinguishing agent is increasing. "Halon" fire extinguishing agent is the culprit of the destruction of the ozone layer. The United Nations was the first to ...
