A gas-propelled fire extinguishing agent used for extinguishing fires in aircraft dry compartments

Abstract

The invention discloses a gaseous propellant fire extinguishing agent for aircraft dry chamber extinguishment. The gaseous propellant fire extinguishing agent is prepared by the following steps: weighing 15-86 parts of solid fuel, 5-50 parts of an oxidizing agent, 1-5 parts of an adhesive, 5-40 parts of a coolant, 5-40 parts of a fire extinguishing agent, and 0.1-2 parts of a lubricant and 0.1-2 parts of a catalyst, uniformly mixing the raw materials, drying, grinding, mixing and preparing. The gaseous propellant fire extinguishing agent disclosed by the invention has the characteristics of being good in stability, high in emission efficiency, high in fire extinguishing efficiency and low in cooling rate. The defects that an existing propellant gas producing agent is bad in stability, high in temperature, bad in fire extinguishing performance and the like are overcome, and the fire extinguishing agent has the very high application prospect in the aircraft dry chamber extinguishment.

Description

technical field [0001] The invention relates to a fire extinguishing agent, in particular to a gas-propelled fire extinguishing agent used for fire extinguishing in an aircraft dry cabin. Background technique [0002] Gas generating agent, also known as gas generating agent, refers to a substance that can generate gas after combustion. In the solid propulsion, the gas generating agent is in the form of solid reactants (fuel and oxidant) to produce a large amount of high temperature, high pressure, high energy gas products, such as nitrogen, water vapor and CO 2 etc., and use the impetus generated by the high-energy gas discharged from the nozzle to propel it forward. [0003] Since the inert gas produced by the gas generating agent has an obvious suppression effect on the fire, in recent years, the research on the application of the gas generating agent in fire extinguishing has gradually increased. However, because the temperature of the gas released by the gas generating...
