Abstract
The aerosol fire extinguishing agent consists of strontium nitrate as oxidant 55-70 wt%, reductant 20-30 wt%, and additive 10-15 wt%. The present invention has raised safety and the insulating performance of the burning product of the fire extinguishing agent. The aerosol fire extinguishing agent has hexamethylene tetraamine as absorbent added into the recipe to absorb the nitrogen oxide produced while the aerosol fire extinguishing agent burns, acting for detoxicating and purifying of the aerosol burning product.
Description
Technical field
The present invention relates to a kind of aerosol fire extinguishing agent, especially a kind of pyrotechnics type aerosol extinguishing agent that can be used for electric equipment.
Background technology
The technology that produces the aerosol fire-extinguishing product with the burning form more and more is subjected to people's attention; and produced the patent achievement of some this respects in succession; as CN97110882.X patent " the aerocolloidal composition and method of making the same of the formation that is used to put out a fire "; the ZL02119648.6 patent " is applicable to the aerosol without toxicity and corrosion extinguishing chemical of electric equipment " etc.; but the oxidant in these aerosol composition prescriptions all contains potassium nitrate; be equipped with phenolic resins and dicyandiamide etc. again and form fire-extinguishing composite; can produce the very strong potassium oxide particulate of a large amount of hygroscopicity during this composition burn; when particulate is deposited in protected equipment surface; can form the very strong potassium hydroxide drop of corrosivity by the airborne moisture of very fast absorption; equipment surface is caused corrosion; simultaneously because drop has strong basicity, can form conductive membrane and cause the electronic equipment circuit to be short-circuited and destroyed.Stability and security meeting are affected during for its burning of the aerosol fire-extinguishing agent prescription that contains guanidine nitrate, because guanidine nitrate is a kind of alternative explosive, inflammable, at high temperature can decompose and explode, mix to be heated also can set off an explosion with the nitrate combustibles, this just greatly threatens the safety in utilization of aerosol fire-fighting equipment.
Summary of the invention
The aerosol fire extinguishing agent that the purpose of this invention is to provide a kind of safe and reliable, nonhazardous that can be used for that the electric equipment place uses.
The present invention is achieved like this, hundred parts of ratios of the composition weight of extinguishing chemical are strontium nitrate 55～70%, reducing agent 20～30%, additive 10～15%, reducing agent comprises fuel and foaming agent, and fuel mainly contains carbon dust, phenolic resins, and foaming agent mainly contains dicyandiamide; Additive comprises combustionregulator and sterilizing and purifying agent, combustionregulator is selected the potassium ferricyanide for use, the mixture of any ratio of one or both in the potassium hyperchlorate, hexa is selected in the sterilizing and purifying agent for use, oxidant strontium nitrate and fuel interaction generate the aerosol based on the inert gas material, play the fire extinguishing effect.Combustionregulator plays catalytic action in fact, be used to improve the burning capacity of this extinguishing chemical, make it have predetermined burn rate, thereby improve the conversion ratio of aerosol composition, the sterilizing and purifying agent then is in order to absorb the nitrogen oxide in the aerosol product, to make it safer harmless nontoxic.
The present invention is a kind of inhibition composition, is made up of oxidant, reducing agent, additive, and oxidant is a strontium nitrate; Its content is up to 55%～70%, do not contain potassium nitrate and guanidine nitrate, the insulating properties of the security when having improved the aerosol extinguishing agent burning and the aerosol product of generation, add hexa in the prescription as absorbent, the nitrogen oxide that produces in the time of can absorbing the aerosol extinguishing agent burning plays the sterilizing and purifying effect to aerosol product.
