Fire-extinguishing composition containing transition metal compound

Abstract

The invention relates to a fire-extinguishing composition containing transition metal compound. The fire-extinguishing composition comprises organic acid salts of elements in the first cycles in the subgroup and the eighth group; and in the fire-extinguishing composition, fireworks drug is used as heat source and power source, and the fireworks drug is driven to react and generate fire-extinguishing substances by setting fire to the fireworks drug. In the composition, the transition metal compound is used as the main component and amine and / or organic amine salt is added to assist to extinguish fire; by using the aerosol which can extinguish fire and is formed by fire-extinguishing substances generated by the decomposing of the tradition metal compound in heating, and a large amount of gas generated by the decomposing of amine and / or organic amine salt in heating, the concentration of the aerosol which can extinguish fire and the air pressure are increased and the spraying strength of the fire-extinguishing substances is improved, and thus the fire-extinguishing efficiency of the fire-extinguishing composition is greatly improved.

Description

technical field [0001] The invention relates to the technical field of fire fighting, in particular to an aerosol fire extinguishing agent containing a transition metal compound. Background technique [0002] Aerosol fire extinguishing agent is a new type of fire extinguishing agent with high fire extinguishing efficiency, zero ozone depletion value ODP, non-toxic and harmless, extremely low residue, and low equipment investment. Under the urgent background of halon elimination, it has received strong support from the government , It also caters to the needs of the market, so the aerosol fire extinguishing technology has become one of the very eye-catching halon replacement technologies in the past ten years. [0003] The fire extinguishing mechanisms of aerosol generating agents are mainly: 1. Heat absorption and cooling; 2. Chemical suppression; 3. Suffocation; 4. Isolation, mainly chemical suppression. Although aerosol generating agents have obvious advantages in fire ex...

AI Technical Summary

Problems solved by technology

Traditional physical cooling will lead to complex and cumbersome structure of the device, complicated process, high cost, and the existence of physical cooling will deactivate a large number of active particles, resulting in greatly reduced fire extinguishing performance

Moreover, the fire extinguishing efficiency is limited, and the cost of the agent causes waste to a certain extent

If the chemical cooling method is used, the coolant is usually placed in the spray direction of the pyrotechnic fire extinguishing agent, but the common chemical coolant will affect the fire extinguishing efficiency of the pyrotechnic fire extinguishing agent. At present, the selection of the fire extinguishing composition is still in the process. In the stage of research and exploration, the fire extinguishing efficiency of its commercialized fire extinguishing agent is not ideal. The stability of the fire extinguishing composition and the injection strength, considered as a whole, make it able to suppress the flame and achieve the purpose of quickly and effectively suppressing the fire source
