Abstract

The invention discloses a smoke suppression type dry powder extinguishing agent. The smoke suppression type dry powder extinguishing agent comprises, by weight, 60-70 parts of ammonium phosphate, 10-15 parts of bentonite, 12-14 parts of aluminium hydroxide, 8-9 parts of magnesium hydrate, 2-4 parts of C6-Fluoroketone, 2-3 parts of diphosphopyridine nucleotide, 2-3 parts of nitric acid dyhydroxy bismuth, 2-3 parts of graphite powder and 1-2 parts of inorganic silica gel. The invention further discloses a preparation method of the smoke suppression type dry powder extinguishing agent. By means of the dry powder extinguishing agent, the defect that an existing dry powder extinguishing agent is used for putting out of fire, the amount of smoke is large can be overcome.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a smoke-suppressing dry powder fire extinguishing agent and a preparation method thereof. Background technique [0002] The dry powder fire extinguishing agent is a fine particle made by mixing the fire extinguishing base material with an appropriate amount of lubricant and a small amount of moisture-proof agent, and it uses carbon dioxide as the injection power. The sprayed powder has a dense concentration and fine particles. Covering the solid combustion material, it can form an isolation layer that hinders combustion, and at the same time precipitates non-combustible gas, which reduces the oxygen concentration in the air and extinguishes the flame. Dry powder fire extinguishing agent can be filled in various types of portable and fixed dry powder fire extinguishing devices. It can be used in combination with fluoroprotein foam fire extinguishing agent and aqueous film-forming foam...
