Problems solved by technology

[0006] In the production process of the traditional anti-alcohol foam fire extinguishing agent, the anti-solvent component is usually added directly to the water, resulting in the anti-solvent component being easy to agglomerate in water, difficult to dissolve quickly, long stirring time, long production cycle of the product, and low production efficiency. low power consumption

Abstract

The invention discloses an efficient low-viscosity easily-degradable anti-soluble compressed air foam extinguishing agent and a preparation method thereof. The extinguishing agent comprises the following components in percentage by weight: 5-25% of a hydrocarbon surfactant, 3-10% of a fluorocarbon surfactant without perfluorooctylsulfonate, 1.5-10% of a low-viscosity anti-soluble component, 3-15%of a foam stabilizer, 5-15% of an antifreeze agent, 0.2-2% of a preservative and the balance of water. The extinguishing agent has the characteristics of high efficiency, low viscosity, low mixing ratio and easiness in degradation; and the mixing ratio is flexibly selected for different fire extinguishing objects, so that various types of fires can be quickly extinguished. All the components of the extinguishing agent can be rapidly biodegraded in the environment and have no pollution to the environment. According to the preparation method, the problems that macromolecular polysaccharide substance powder is easy to agglomerate in the water, long in swelling time and difficult in uniform component mixing in a traditional adding method are effectively avoided, and the foaming condition of the extinguishing agent in the production process is effectively controlled, so that the production efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a high-efficiency, low-viscosity and easily degradable type anti-solvent compressed air foam fire extinguishing agent and a preparation method thereof. Background technique [0002] Alcohol-resistant foam fire extinguishing agent refers to the foam fire extinguishing agent that can resist the destruction of foam when the foam produced is applied to the surface of alcohol or other polar flammable and flammable liquids. It is widely used in alcohols, esters, ethers, and ketones. Fire fighting of similar polar flammable and flammable liquids. At present, the commonly used anti-alcohol foam fire extinguishing agent has a mixing ratio of 3% and 6%, among which the product with a high mixing ratio of 6% is used the most. Compared with conventional high mixing ratio foam products, highly concentrated low mixing ratio foam fire extinguishing agent products The advantages of high concentrati...
