Problems solved by technology

However, the fire extinguisher prepared with nitrogen as a propellant will have insufficient impact force in the later process of use.
The one-pack fire extinguisher with carbon dioxide as the propellant will corrode the tank during storage and cause the tank to leak
Moreover, in the prior art, flame retardants are generally diammonium hydrogen phosphate, ammonium dihydrogen phosphate, and polyphosphate amine, etc. These commonly used flame retardant ingredients are all phosphorus-containing ingredients, which will cause eutrophication of water bodies

Abstract

The invention belongs to the field of combined type fire extinguishing agent processing, and specifically relates to a combined type fire extinguishing agent and a preparation method thereof. The fireextinguishing agent is composed of a propellant and a feed liquid in a weight ratio of (2-15) to 100; the feed liquid comprises a surfactant, a foaming agent, a thickening agent, a foam stabilizer, acorrosion inhibitor, a flame retardant, a foam reinforcing agent, a penetrating agent, a solvent, an indicator and a pH regulator; the propellant is composed of nitrogen gas and carbon dioxide. The foaming agent is formed by mixing a plurality of substances. The fire extinguishing agent selects a fluorine-containing surfactant and the foam stabilizer which is not used by other fire extinguishingagents, and each component agent is formed by combined type component matching, so that very good foaming effect and very good foam-stabilizing effect can be achieved; the propellant is combined in various ways, and meets the jetting effect better in comparison with a single propellant; and used raw materials do not contain phosphor, so that eutrophication of a water body is not caused, and therefore, the combined type fire extinguishing agent is very strong in environment friendliness, and has an extremely great market prospect and an extremely great economic value.

Description

technical field [0001] The invention belongs to the field of fire extinguishing agent processing, and in particular relates to a combined fire extinguishing agent and a preparation method thereof. Background technique [0002] At present, in the prior art, the propellant in the fire extinguisher usually adopts single nitrogen or carbon dioxide. However, the fire extinguisher prepared with nitrogen as the propellant will have insufficient impact force in the later course of use. The one-pack fire extinguisher with carbon dioxide as the propellant will corrode the tank during storage and cause the tank to leak. Moreover, in the prior art, flame retardants are generally diammonium hydrogen phosphate, ammonium dihydrogen phosphate, and amine polyphosphate, etc., and these common flame retardant components are all phosphorus-containing components, which will cause eutrophication of water bodies. [0003] Therefore look for a kind of fire extinguishing effect good, impact force ...
