Abstract
The present invention relates to an aerosol fire extinguishing agent which comprises an oxidizing agent, an incendiary agent, a composite catalyst and a molding auxiliary agent. The fire extinguishing agent is composed of components of the weight percentage: 50% to 70% of potassium nitrate and/or sodium nitrate serving as the oxidizing agent, 20% to 30% of incendiary agent, 2%-10% of composite catalyst and 5%-20% of solidifying molding auxiliary agent, wherein the incendiary agent is selected from multiple carbon alcohol superior than hexanol and high molecular compound with amido, and the composite catalyst is a mixture of ferrocene and potassium sulfate. The fire extinguishing agent has high fire extinguishing efficiency, high fire extinguishing speed, no harm to human bodies, animals or substances and no destruction action on the atmospheric ozone layer. In addition, the fire extinguishing agent has stable inexplosive performance, and the fire extinguishing agent can not explode under any extremely strong detonating conditions with favorable physical stability and chemical stability.
Description
The present invention relates to a kind of fire-extinguishing agent, more specifically to aerosol fire extinguishing agent.
The aerosol type extinguishing chemical is a class extinguishing chemical of developing recently in the fire extinguishing field, and it forms aerosol product by the fuel in the flame combustion extinguishing chemical, thereby reaches the fire extinguishing purpose.Prior art such as Muscovite CN1166996A patent, its aerosol fire-extinguishing agent prescription is the dicyandiamide of 62-72% potassium nitrate, 8-12% phenolic resins and surplus, owing to wherein contain the compound dicyandiamide of being with cyano group, in combustion process, can produce the noxious material of cyanate, human body and surrounding environment are worked the mischief.Contain a large amount of perchlorate in the extinguishing chemical prescription of Russ P RU2058800, will produce strong corrosivity like this, people and object are all had serious harmfulness.Existing in addition aerosol type extinguishing chemical fire-fighting efficiency is lower, and has the possibility that is detonated, poor stability.A kind of aerosol extinguishing agent is also disclosed in the inventor's the CN9310587.6 of patent application formerly (being in the checking process), it mainly is made up of oxidant such as potassium nitrate and sodium nitrate, incendiary agent such as iditol etc., curing molding agent, it is that fire-fighting efficiency is lower, blow-off velocity is unhappy that there is a subject matter in this extinguishing chemical, and wherein all there are toxicity problem in the additives of Cai Yonging such as the potassium ferricyanide in production and use.
Purpose of the present invention is just for fear of the deficiency of above-mentioned prior art and a kind of aerosol fire extinguishing agent of designing.The fire-fighting efficiency height of this extinguishing chemical, blow-off velocity are fast, have good non-detonation property, and security is good.
The said aerosol fire extinguishing agent of the present invention comprises oxidant, incendiary agent, composite catalyst and shaping assistant, by weight percentage, the prescription of this extinguishing chemical is: oxidant: potassium nitrate and/or sodium nitrate 50-70%, incendiary agent 20-30%, composite catalyst 2-10% and curing molding auxiliary agent 5-20%, wherein said incendiary agent are selected from the above higher alcohols class of six carbon alcohol and contain amino macromolecular compound class; Said composite catalyst is the mixture of ferrocene and potassium sulfate, and preferably wherein the weight ratio of ferrocene and potassium sulfate is 4: 1.
The characteristics of aerosol extinguishing agent of the present invention are its fire-fighting efficiency height, and blow-off velocity is fast, and harmful to human, animal and object do not have destruction to atmospheric ozone layer.It has stable non-detonation property in addition, and under extremely strong strong ignition condition, this extinguishing chemical can detonation.Measure with control National Laboratory through explosion disaster prevention, all can not produce detonation adopting No. 8 military electric caps, TNT explosive and 8701 high explosives to ignite under the condition of extinguishing chemical of the present invention respectively.This is the key property that it is different from other aerosol type extinguishing chemical.This has just prevented that aerosol extinguishing agent is utilized the possibility as other illegal purposes well.This point is the essential condition that can aerosol extinguishing agent be used by large-scale popularization.
With the exception of this, extinguishing chemical of the present invention proves after testing and itself has good physics stability and chemical stability.Zoopery through the parties concerned proves, the animal after experimentizing under the condition of twice fire-fighting dose all survives well through long-term observation, does not produce any bad reaction.Now the minimum fire extinguishing consumption with extinguishing chemical of the present invention and several total flood fire suppression agent compares, and it the results are shown in the following table:
The foamite amount contrast
Annotate: CTK is a kind of aerosol type extinguishing chemical of being produced by Russia

Incendiary agent in the aerosol fire-extinguishing agent prescription of the present invention is that the above higher alcohols of six carbon alcohol contains amino macromolecular compound with other, as: amino tetrapyrrole of 5-and inositol etc.The curing molding auxiliary agent can use molding adhesive commonly used in this area, preferably is selected from epoxy resin and other high polymer binder.
The present invention is owing to adopting distinctive composite catalyst to make fire-fighting efficiency and blow-off velocity obtain raising, this is the pith that the present invention is different from prior art, and it also makes the present invention avoid using the toxic component such as the potassium ferricyanide, thereby has improved the security to human body and surrounding environment.Composite catalyst of the present invention can adopt the ferrocene after the coating, as the mixture of ferrocene microcapsules and potassium sulfate.
Ferrocene after the coating is with after potassium sulfate mixes, initial period and end product to the combustion product generation, all bring bigger influence, composite catalyst makes burning condition be in stable state, and end product is carried out towards the state that helps improving fire-fighting efficiency.
Illustrate below by embodiment and to describe the present invention, be understood that these embodiment only are used for describing, rather than will carry out any qualification the present invention.
Embodiment 1:
At first the ferrocene powder below the 100 μ m is overmolding to the ferrocene microcapsules with polyvinyl alcohol.Ferrocene after coating mixes with potassium sulfate below the 5 μ m with 4: 1 weight ratio, thereby makes the said composite catalyst of the present invention.
Take by weighing 15 kilograms in 50 kilograms in potassium nitrate and sodium nitrate, they are ground into powder below the 5 μ m.Be ground into the following powder of 5 μ m in the above after getting 20 kilograms of inositol again and 5 kilograms of composite catalysts that make mixing.Then above-mentioned two kinds of powders are mixed and get final product curing molding after the back epoxy resin that adds 10 kilograms is mediated.
