Abstract

The invention provides a fire extinguishing agent. The fire extinguishing agent is prepared by mixing and dispersing hydrophobic solid particles, water-soluble surfactant and water solution according to mass ratio of (5-100):(0.001-2):100. The fire extinguishing agent can simultaneously play stifling, cooling and chemical inhibition roles, and the fire extinguishing efficiency is high. Compared with the existing fire extinguishing agent, according to the fire extinguishing agent, due to addition of the surfactant in the water phase, the dispersion of rotating speed in preparation process can be lowered, the dispersion time can be shortened, and the preparation efficiency can be improved; and with the fire extinguishing agent, the adhesion property of solid gas interface and liquid gas interface can be greatly improved, the usage amount for extinguishing fire can be greatly reduced, and the fire extinguishing property can be obviously improved.

Description

technical field [0001] The invention belongs to the technical field of fire extinguishing materials, and in particular relates to a fire extinguishing agent. Background technique [0002] Water is a frequently used extinguishing agent whose thermal properties make it useful in the extinguishing process for most types of fires. However, the fluidity of water is very strong, and most of the water used for fire extinguishing is lost before it can take effect under normal circumstances, resulting in a low utilization rate of water fire extinguishing, and it is easy to cause secondary losses and environmental pollution. Chinese patent 201010605644.5 provides a fire extinguishing agent, the fire extinguishing agent effectively restricts the free flow of water by binding water in a solid shell, has a certain accumulation, and reduces the amount of fire extinguishing agent and improves the fire extinguishing effect. The secondary disaster caused by water during fire extinguishing i...
