Fire extinguishing agent based on hydrophobic particle flame retardance

Abstract

The invention discloses a flame-retardant fire extinguishing agent based on hydrophobic particles, which consists of 4.9-9.5 parts by mass of foaming agent, 3.5-8.6 parts by mass of stabilizer, 26.5-43.5 parts by mass of hydrophobic solid particles, and the rest is an aqueous solution The mixture formed, the foaming agent is vegetable hydrolyzed protein or licorice powder; the stabilizer is ferric chloride, and the hydrophobic solid particles are fly ash particles, potassium salt dry powder, ammonium dihydrogen phosphate dry powder, phosphoric acid A mixture of one or more of diamine dry powder, phosphoric acid dry powder, amino dry powder, and mica particles; the solvent of the aqueous solution is water, and the solute is one or more of potassium bicarbonate, sodium carbonate, ammonium carbonate, and potassium chloride mixture of species. The fire extinguishing agent provided by the present invention can evenly adhere to the oily substance, and the foaming agent can rapidly combine the uncovered area freely to form a covering layer, which isolates the necessary oxygen needed for combustion, and forms combustibles and The physical isolation between oxygen has achieved the effect of fire extinguishing.

Description

technical field [0001] The invention relates to the field of fire-fighting materials, in particular to the field of fire extinguishing agents used for fire extinguishing, specifically, a fire extinguishing agent based on hydrophobic particles for flame retardancy. Background technique [0002] A fire extinguisher is a portable fire extinguishing tool. Chemicals are placed in the fire extinguisher to put out the fire. Fire extinguishers are one of the common fire prevention facilities. They are stored in public places or places where fires may occur. Different types of fire extinguishers contain different ingredients and are specially designed for different fire alarms. Care must be taken during use to avoid adverse effects and danger. [0003] Existing fire extinguishing agents mainly include foam and dry powder, both of which have their own advantages and disadvantages. The fire extinguishing agent in a dry powder fire extinguisher is filled with ammonium phosphate for fi...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a fire extinguishing agent based on hydrophobic particles, which solves the problems that the dry powder fire extinguisher in the prior art is not easy to extinguish oily fires and the fire extinguishing efficiency of the foam fire extinguishing agent is relatively low.
