Continuous and stable solubility-resisting foam fire extinguishing agent

Abstract

The invention belongs to the technical field of fire service inventories, and relates to a continuous and stable solubility-resisting foam fire extinguishing agent. The continuous and stable solubility-resisting foam fire extinguishing agent is formed by, by mass percent, 1.2%-3.0% of a fluorocarbon surfactant, 0.5%-1.5% of a fluoride-free surfactant, 1.5%-3.5% of perfluor glycine betaine, 2%-5% of fluorate alkyl dimethyl betaine, 3%-5% of urea, 5%-15% of modified succinic acid ester, 0.8%-1.5% of xanthan gum, 5%-8% of lauryl tetrahydroglyoxaline glycine betaine, 5%-8% of cocamidopropyl cocamidopropyl betaine, 10%-20% of ethylene glycol, 0.1%-0.3% of xanthan gum, 0.5%-1.0% of a foam stabilizer, 0.8%-1.5% of a cosolvent, 0.1%-0.2% of a thickening agent and the balance water. The continuousand stable solubility-resisting foam fire extinguishing agent is scientific in component; and compared with a traditional solubility-resisting foam fire extinguishing agent, the large thickness of thesolubility-resisting foam fire extinguishing agent can be formed, during fire extinguishing, the temperature reduction speed is high, the fire extinguishing effect is good, after-combustion is not prone to happening, stability performance is high, and the fire extinguishing rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting supplies, and relates to a foam fire extinguishing agent, in particular to a continuous and stable anti-solvent foam fire extinguishing agent. Background technique [0002] Foam fire extinguishing agent is an effective fire extinguishing agent for extinguishing flammable and combustible liquids. It mainly generates a condensed foam floating layer on the surface of the liquid to suffocate and cool. Foam fire extinguishing agents are divided into chemical foam, air foam, fluoroprotein foam, aqueous film-forming foam and alcohol-resistant foam. [0003] Water-soluble flammable liquids, such as alcohols, esters, ethers, aldehydes, organic acids and amines, etc., because of their strong molecular polarity, can absorb a large amount of water in the foam, so that the foam will be destroyed quickly without fire extinguishing effect, so it cannot be used Protein foam, fluoroprotein foam, and light w...

Problems solved by technology

[0007] Aiming at the deficiencies of the existing solvent-resistant foam fire extinguishing agent, the thickness of which cannot reach the covering ability, the cooling speed is too slow, the fire extinguishing speed is slow, the fire extinguishing effect is poor, it is easy to re-ignite, and the stability is poor, etc., and proposes a continuous and stable anti-foam fire extinguishing agent. The soluble foam fire extinguishing agent can solve the deficiencies in the above-mentioned prior art, can enhance the film thickness of the fire extinguishing agent, is stable in use, and can increase the speed of fire extinguishing
