Abstract

The invention relates to a rapid and efficient aerosol fire extinguishing agent and a preparation method thereof and belongs to the field of fire protection engineering. With the total mass of raw materials of the aerosol fire extinguishing agent being 100%, the aerosol fire extinguishing agent is prepared from, by mass, 60-80% of an antioxidant, 10-30% of a combustible agent, 0-15% of a modifier and 1-5% of an adhesive. The preparation method of the aerosol fire extinguishing agent includes the steps that firstly, the antioxidant, the combustible agent and the modifier are dried at 50-80 DEG C and then mixed evenly; then, the adhesive dissolved in ethyl alcohol or acetone is added, granulation is carried out with a screen after full and even mixing, and the granulated material is dried at 50-80 DEG C; then, the dried material is subjected to compression moulding forming with a mould, and the aerosol fire extinguishing agent is obtained. The aerosol fire extinguishing agent is easy to ignite, high in combustion speed, capable of generating a large amount of fire extinguishing matter within a short time, full and stable in combustion and high in fire extinguishing efficiency. According to the preparation method, the process is simple, the raw materials are easy to obtain, and the preparation cost is low.

Description

technical field [0001] The invention relates to a fast and efficient aerosol fire extinguishing agent and a preparation method, belonging to the field of fire engineering. Background technique [0002] Halon fire extinguishing agent has been widely used in the fields of fire extinguishing, explosion prevention and explosion suppression because of its high efficiency, cleanness, non-toxic and harmless performance, but it has been eliminated due to the damage effect of halogenated alkanes on the ozone layer. Aerosol fire extinguishing agent, as a substitute product of halon fire extinguishing agent, has become a research hotspot at home and abroad because of its high fire extinguishing efficiency, no damage to the ozone layer and low production cost. The combustion of aerosol fire extinguishing agent can produce a large amount of gas / solid phase components. Because of its chemical inhibition, physical isolation and cooling effect, it can quickly extinguish fires. It is suitabl...
