Abstract

The invention discloses an efficient environment-friendly flame-retardant fire extinguishing agent. The fire extinguishing agent comprises, by weight, 8-15% of quaternary ammonium salt-15 modified meso-tetramethyl-meso-tetra-p-aminohphenylcalix[4]pyrrole, 2-5% of hydrogenated lecithin, 1-3% of tea polyphenol, 3%-8% of 3-chloromethylphenylboronic acid modified N,N-bis(2-hydroxyethyl)-2-taurine, 2%-4% of guanosine, 0.3%-1% of an anti-freezing agent, 0.1%-0.5% of a preservative, 0.8%-1.5% of a stabilizer and the balance water. The invention further discloses a preparation method of the efficientenvironment-friendly flame-retardant fire extinguishing agent. The efficient environment-friendly flame-retardant fire extinguishing agent is high in fire extinguishing efficiency, good in fire extinguishing effect, capable of effectively preventing after-combustion, safe and environmentally friendly to use, large and stable in impact force, not prone to leakage and free of corrosion to a tank body.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to an efficient and environment-friendly flame retardant fire extinguishing agent and a preparation method thereof. Background technique [0002] In recent years, with the advancement of the construction pace of high-rise residential projects and various household appliances increasingly entering people's daily life, various fire accidents have occurred from time to time, causing huge losses to people's lives and property. Therefore, in the event of a fire How to effectively extinguish the fire and make it difficult for combustibles to burn, so as to prevent or delay the fire and leave precious time for rescue and escape after the event is very important. [0003] At present, fire extinguishers are an important tool for extinguishing fires, and the fire extinguishing agent is the key to determine the performance of fire extinguishers. A fire extinguishing agent is...
