A fire extinguishing composition containing a transition metal compound

Abstract

The present invention relates to a fire extinguishing composition containing a transition metal compound, comprising a salt of an organic acid of first period elements in a subgroup and the group VIII; and using a pyrotechnic agent as a heat source and a power source, reacting through heat emitted by igniting the pyrotechnic agent to burn and outputting a fire extinguishing material. In the present invention, a transition metal compound is selected as a primary ingredient, then an amine and / or organic amine salt is added to assist in fire extinguishing, a fire extinguishing aerosol is formed by using the fire extinguishing material generated by heating and decomposing the transition metal compound, and meanwhile the amine and / or organic amine salt is heated and decomposed to generate a great quantity of gas, thereby increasing the concentration and the air pressure strength of the fire extinguishing aerosol, improving the injection strength of the fire extinguishing material, and greatly improving the fire extinguishing performance of the fire extinguishing composition.

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
