A fire-extinguishing composition comprising an organic acid compound with a high content (50% or more) that absorbs heat and decomposes to release fire-extinguishing substances, achieving both physical and chemical inhibition effects, combined with a pyrotechnic agent and optional flame retardants and additives for enhanced performance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional aerosol fire extinguishing agents are used, then fire-extinguishing effect is achieved through oxidation-reduction reactions, but the device structure becomes complex and bulky due to the need for cooling systems
Solution Approach 1:
The patent extracts and removes the cooling system from the fire extinguishing device, replacing the traditional oxidation-reduction reaction mechanism with a decomposition reaction of organic acid compounds that inherently provides both fire suppression and cooling effects without requiring separate cooling components
Solution Approach 2:
The patent changes the chemical reaction parameters from oxidation-reduction to decomposition reactions of organic acid compounds, altering the fundamental mechanism to eliminate the need for complex cooling systems while maintaining fire-extinguishing effectiveness
2Reliability
If gas fire extinguishing systems are stored under high pressure, then fire-extinguishing capability is maintained, but the volume occupied increases and physical explosion risk arises
Solution Approach 1:
The patent changes the storage parameters from high-pressure gas storage to ambient temperature solid/liquid organic acid compound storage, fundamentally altering the physical state and storage conditions to eliminate explosion risks while maintaining fire suppression capability through controlled decomposition
Solution Approach 2:
The patent employs organic acid compounds that can be stored stably and activated on-demand through decomposition, replacing the need for continuously pressurized systems with a more stable, on-demand fire suppression approach
3Reliability
If aerosol generating agents release fire-extinguishing substances during combustion reactions, then active particles are generated, but a large amount of heat is released requiring cooling systems that inactivate particles
Solution Approach 1:
The patent extracts and eliminates the cooling system that causes particle inactivation, using organic acid compound decomposition reactions that generate fire-extinguishing substances without the excessive heat release that inactivates active particles in traditional systems
Solution Approach 2:
The patent creates a simplified version of the fire suppression mechanism that copies the essential function of generating fire-extinguishing substances without replicating the harmful heat release and particle inactivation effects of traditional combustion-based systems

AI summary
The disclosure relates to a fire-extinguishing composition comprising an organic acid compound, wherein the fire-extinguishing composition comprises an organic acid compound. The content of the organic acid compound is 50% by mass or more, and preferably 70% to 90% by mass. The organic acid compound according to the disclosure may absorb heat and be decomposed at a high temperature, and release a fire-extinguishing substance. The fire-extinguishing substance may react, by means of free radicals, with one or more of O·, OH·, H· free radicals that are necessary for chemical-looping combustion, thus cutting off the chemical-looping combustion, or may reduce the oxygen partial pressure by physical action to inhibit the flame, or achieve the fire-extinguishing effect by both the physical and chemical inhibition effects. At the same time, the organic acid compound achieves a synergistic effect together with a pyrotechnic agent, thereby further improving the fire-extinguishing performance of the fire-extinguishing agent, and greatly shortening the effective fire-extinguishing time.
