Abstract

The invention relates to a neutral water-system fire extinguishing medium and a preparation method thereof. The neutral water-system fire extinguishing medium is composed of phosphorus flame retardant, nitrogenous flame retardant, gels, a surface active agent, water glass, a PH adjusting agent and the balance distilled water. The preparation method comprises the following steps of S1, material mixing; S2, adjustment of the PH value; S3, curing; and S4, manufacturing of a finished product. The neutral water-system fire extinguishing medium has the advantages of being environmentally friendly, safe, wide in use temperature range and good in flame resistance.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing agents, in particular to a neutral water-based fire extinguishing agent and a preparation method thereof. Background technique [0002] Fire extinguishing agent refers to the substance that can effectively destroy the burning conditions and stop the burning. Water is an odorless and tasteless liquid, and it is the basic substance for human beings to survive. The water is easy to use and widely distributed. At the same time, the water is chemically neutral, non-toxic, has a large specific heat capacity and heat of vaporization, and has a good cooling effect. Water can directly take away the high-temperature combustion products of the flame and the heat on the fuel surface; water can absorb heat energy very effectively during the vaporization stage; the steam generated by water occupies the combustion area, which can prevent fresh air from entering the combustion area, thereby reducing t...
