Concentrated solution of type A foam extinguishing agent and preparation method thereof

Abstract

The invention relates to a class A fire-extinguishing foam concentrated liquid and a preparation method thereof. The fire-extinguishing foam comprises the following components in permillage by weight: 500 to 600 permillage of surfactant, 30 to 50 permillage of pour point depressant, 50 to 80 permillage of flame retardant, 1 to 2 permillage of stabilizing agent, 50 to 100 permilage of solvent, 1 to 2 permillage of preservative and the balance being deionized water, wherein the surfactant is one of C6 to C18 alkyl polyglycosides, C6 to C18 alkyl betaine or C6 to C18 alkyl imidazoline; and the preparation method comprises the following steps: adding the stabilizing agent, the preservative and the flame retardant into the deionized water in turn; and after evenly stirring, adding the rest components, namely the surfactant, the pour point depressant and the solvent, and stirring the mixture evenly to prepare the product. The extinguishing agent has brand-new components, has foams with strong adhesive force and long persistence, has good heat insulation and heat radiation resistant effects, can effectively control after-combustion of solid combustible substances, greatly reduce operation strength and improve on-site extinguishing efficiency, has wide extinguishing range and high fire demand utilization rate, and is mainly used for extinguishing class A fire; and the preparation method is scientific, reasonable, simple and feasible.

Description

technical field [0001] The invention relates to a class A foam fire extinguishing agent concentrate and a preparation method, which is mainly used for extinguishing class A fires. Background technique [0002] Class A fires are solid substance fires. This substance often has the nature of organic substances, and generally produces glowing embers when burned, such as fires such as wood, coal, cotton, wool, hemp, and paper. As cities become larger and more expensive, Class A fires cause more and more losses to the society, making it more difficult to fight fires, posing a huge threat to life and property. The fire extinguishing method of Class A fire generally adopts water cooling method and ordinary foam fire extinguishing agent, but for substances that avoid water, such as cloth, paper, etc., the loss caused by water stains should be minimized, and carbon dioxide, halogenated alkanes, and dry powder fire extinguishing agents are generally used Extinguishing. But these sev...
