The present invention relates to a novel aging-resistant aerosol generating agent and preparation method thereof. The aging-resistant aerosol generating agent in the present invention comprises oxidizer, reducer and bonding agent, wherein the oxidizer is potassium nitrate, the bonding agent is phenolic resin, and the reducer is melamine; the weight percentages of the three constituents are: potassium nitrate: 60˜80%, phenolic resin: 8˜15%, and melamine: the rest. In the preparation process, phenolic resin is dissolved in ethanol to give phenolic resin solution at concentration by 40˜50 wt %; the oxidizer and reducer are pulverized, mixed, and then the phenolic resin solution is added to the mixed powder; next, the mixture is agitated, pelletized, dried, and shaped by pressure molding. Compared to that in the prior art, the aerosol generating agent in the present invention has higher fire suppression efficiency and higher fire suppression rate, and greatly improved aging resistant performance.

The initiator is applicable to various aerosol fire suppression apparatuses.
摘要:
A fire extinguishing composition generating fire extinguishing substance through chemical reaction of ingredients at high temperature, wherein: the fire extinguishing composition comprises a flame retardant, an oxidant, a reducing agent and an adhesive; contents of each ingredient are: the flame retardant: 50 wt % to 90 wt %; the oxidant: 5 wt % to 30 wt %; the reducing agent: 5 wt % to 10 wt %; the adhesive: 0% to 10 wt %. In a usage of the fire extinguishing composition, a pyrotechnic agent is adopted as a heat source and a power source; and the purpose of fire extinguishing is achieved by: igniting the pyrotechnic agent, and the oxidant and the reducing agent in the fire extinguishing composition are reacted to generate the in the use of high temperature produced by burning the pyrotechnic agent. by burning the pyrotechnic agent, so as to implement fire extinguishing. Different from the traditional aerosol generating agent, there is no external heat source, and the composition itself does not burn. Compared with the traditional aerosol generating agent, the fire extinguishing composition of the present invention is more efficient and safer.
