Abstract

The invention discloses a special fire extinguishing agent for a sealed or semi-sealed space. The special fire extinguishing agent for the sealed or semi-sealed space is prepared from the following components in parts by weight: 30%-50% of water, 20%-40% of an inorganic composite gel solution, 10%-20% of sodium bicarbonate, 2%-8% of silicone oil, 5%-15% of a flame retardant and 1%-3% of a stabilizer, wherein the inorganic composite gel solution is prepared from aluminum chloride hexahydrate, pentafluoropropane and glucomannan through chemical treatment. Compared with the prior art, the prepared fire extinguishing agent special for the sealed or semi-sealed space has the advantages of being easy to store and convenient to use, has good infiltration capacity, water retention capacity and combustion suppression effect in the fire extinguishing process, and can remarkably reduce fire temperature and emission of toxic gas.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a special fire extinguishing agent for sealed or semi-sealed spaces. Background technique [0002] Fire accidents pose a huge threat to human life and property safety. Finding new chemicals that can effectively inhibit flame spread and exhibit high fire extinguishing performance is an important fire safety issue. Water is by far the most common substance used to extinguish fires. Regular water is very effective in suppressing flames due to its unique physical properties due to its special cooling, insulating and diluting abilities. The use of dispersed water can greatly improve the cooling effect of water, and the use of water mist also reduces the flux of water application. The reason why the dispersed water has such a significant cooling effect is due to the increased heat transfer coefficient of the water droplets and the shortened heating time, because in this case...
