Extinguishing agent

Abstract

The invention discloses an extinguishing agent. The extinguishing agent is formed by mixing and stirring strong hydrophobic solid particles and aqueous solution at high speed, wherein the strong hydrophobic solid particles are one type or more of magnesium hydroxide particles, silicon dioxide particles, calcium carbonate particles, talcum particles, aluminium oxide particles, aluminium hydroxide particles, zinc borate particles, zinc oxide particles, iron sesquioxide particles, titanium dioxide particles, montmorillonite particles, hydrotalcite particles, coal ash particles, diatomite particles, mica particle, attapulgite particles and zeolite particles after hydrophobic modification. The extinguishing agent disclosed by the invention is nontoxic, environmental pollution is less, and secondary loss caused by strong flowability of water can be avoided while playing the advantages of the water as the extinguishing agent and reducing the using amount.

Description

technical field

[0001] The invention belongs to the technical field of chemical industry, and in particular relates to a fire extinguishing agent. 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 the concentration of oxygen in the combustion area...
