Abstract

The invention provides a gas generating agent of a fire-extinguishing device and a preparation method thereof and relates to the technical field of fire fighting and fire extinguishing. The gas generating agent comprises a main component and auxiliary components, wherein the main component is prepared by the following materials in percent by weight: 60-70% of potassium nitrate, 10-20% of melamine and no less than 5% of foaming agent; and the auxiliary components comprise the following materials in percent by weight: 6-12% of adhesive and no more than 5%. The gas generating agent provided by the invention has the advantages that the components are simple, the cost is low, the generated gas is stable in pressure and strong in continuity, and the gas generation amount is large, so that the fire extinguishing efficiency of the fire-extinguishing device is high and the like.

Description

technical field [0001] The invention relates to the technical field of fire fighting and fire extinguishing, in particular to a gas generating agent for a fire extinguishing device and a preparation method thereof. Background technique [0002] The fixed non-storage fire extinguishing device is an atmospheric fire extinguishing device that does not need energy storage. It can be quickly activated in case of fire and is widely used in unattended places. The fire extinguishing device is composed of a shell, a fire extinguishing agent and a starter. Extinguishing agents include dry powder, foam, etc. In the existing non-pressure storage fire extinguishing device, the starter adopts the gas-generating agent driven by gas. After receiving the start signal, the gas-generating agent expands rapidly, changes from solid to gas, breaks through the sealing port, and sprays the fire extinguishing agent into the fire scene to extinguish the fire. [0003] The gas generating agent in th...
