Fire extinguishing agent based on hydrophobic particle flame retardance

Abstract

The invention discloses a fire extinguishing agent based on hydrophobic particle flame retardance. The fire extinguishing agent based on hydrophobic particle flame retardance is a mixture composed of4.9-9.5 parts by mass of a foaming agent, 3.5-8.6 parts by mass of a stabilizer, 26.5-43.5 parts by mass of hydrophobic solid particles, and the balance an aqueous solution. The foaming agent is vegetable hydrated protein or licorice powder. The stabilizer is ferric trichloride. The hydrophobic solid particles are a mixture of one or more of coal ash particles, sylvite dry powder, ammonium dihydrogen phosphate dry powder, phosphorus diamine dry powder, phosphoric acid dry powder, amidogen dry powder and mica particles. The solvent of the aqueous solution is water, and the solute of the aqueoussolution is a mixture of one or more of potassium bicarbonate, sodium carbonate, ammonium carbonate and potassium chloride. The fire extinguishing agent provided by the invention can be evenly adsorbed on oil materials, the foaming agent can be rapidly combined with an uncovered area in a dissociating mode to form a covering layer, oxygen necessary for combustion is isolated, physical isolation between inflammable goods and oxygen is formed, and the fire extinguishing effect is achieved.

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...

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.
