Definitions
- the present invention is in the field of fire protection, and relates to a novel and highly effective fire extinguishing composition, and more particularly to a ferrocene-based fire extinguishing composition using ferrocene and its derivatives as main fire extinguishing materials.
- Gas fire extinguishing systems, dry powder fire extinguishing systems and water fire extinguishing systems are widely used as substitutes for halon fire extinguishing agents because they are environmentally friendly.
- the extinguishing mechanism of carbon dioxide, IG541 and other inert gas fire extinguishing systems is mainly physical fire extinguishing.
- the fire extinguishing is suffocated by reducing the oxygen concentration in the fire zone. This kind of fire extinguishing method is easy to pose a threat to the personal safety of the personnel.
- the dry powder fire extinguishing system is operated by the pressurized gas. The sprayed powder is in contact with the flame, and physicochemical inhibition occurs to extinguish the fire.
- the water mist extinguishing system achieves the purpose of controlling fire, suppressing fire and extinguishing fire by the triple action of cooling by fine water mist, suffocation and heat radiation. .
- the existing aerosol fire extinguishing agents mainly include S-type and K-type fire extinguishing agents.
- Aerosol fire extinguishing agents use redox reaction to release a large amount of gas and active.
- the particles through the chain scission reaction of the active particles, cover the suffocation of a large amount of gas, and achieve the purpose of combining fire and chemical.
- the combustion reaction of the aerosol fire extinguishing agent releases a large amount of heat while releasing the aerosol.
- the cooling system needs to be added, resulting in a complicated and cumbersome structure and complicated process.
- the cost is high, and due to the presence of the cooling system, a large number of active particles are inactivated, resulting in greatly reduced fire extinguishing performance. Summary of the invention
- the ferrocene-based fire extinguishing composition of the present invention comprises ferrocene, a ferrocene derivative or a combination thereof in an amount of 25 mass% or more.
- the ferrocene-based fire extinguishing composition of the present invention may suitably incorporate various flame retardants, additives and the like which are commonly used in the art.
- the ferrocene-based fire extinguishing composition of the invention can simultaneously achieve the following effects: 1.
- the ferrocene-based fire extinguishing composition releases a large amount of effective fire extinguishing substance at the moment of heating, and the fire extinguishing substance is mainly composed of liquid or solid particles, and passes through various particles. Synergistic effect, greatly shortening the fire extinguishing time; Second, through the flame retardant effect of the decomposition products, while reducing the possibility of re-ignition of the fire source, the fire extinguishing efficiency of the fire extinguishing agent is further improved; 3.
- Ferrocene fire extinguishing composition In the case of high temperature and heat, the endothermic decomposition can occur rapidly, effectively reducing the heat released by the pyrotechnics combustion, greatly reducing the temperature of the fire extinguisher spout and the discharge material, eliminating the complicated cooling system of the fire extinguishing device, and eliminating the The risk of secondary fires occurs; Fourth, the fire extinguishing composition is easy to process and can be used alone or in combination with physical coolant; 5. Stable performance and easy long-term storage; 6. Low toxicity or non-toxicity, environmentally friendly performance excellent.
- the ferrocene-based fire extinguishing composition of the present invention comprises ferrocene, a ferrocene derivative or a combination thereof in an amount of 25 mass% or more.
- ferrocene is added to the fire extinguishing composition, but it is added as an additive, and the amount added is very small, about 5% by mass or less.
- the inventors have found through a large number of experiments that when a ferrocene or a ferrocene derivative is used as a main fire extinguishing material (content: 25 mass% or more), an excellent fire extinguishing effect can be obtained, and it is environmentally friendly.
- the flame suppression mechanism of ferrocene or ferrocene derivatives is as follows: Gas phase ferrocene or its derivatives A gas phase pyrolysis of iron atoms, the iron reacts with oxygen to generate Fe0 2, Fe0 2 captures oxygen free radical chain reaction of combustion generated FeO.
- FeO is an unstable active substance. It reacts with Fe(OH) 2 and FeOH to form a catalytic cycle of hydrogen atom recombination.
- Fe(OH) 2 can capture hydrogen radicals in chain combustion reaction to form FeOH.
- FeOH can continue.
- the hydrogen radicals carried out by the chain combustion reaction are consumed to form FeO, and a cycle in which FeO consumes hydrogen radicals is formed, thereby blocking the chain combustion reaction.
- the iron particles or other active particles released during the decomposition process also synergistically with the fire extinguishing substances released from the pyrotechnic agents and the auxiliary components of the fire extinguishing composition, further improving the synergistic effect.
