Abstract
The invention provides magnesium-based S type aerosol fire extinguishing agent capable of solving such problems as low fire extinguishing efficiency, high residual rate, high combustion temperature and weak combustion performance stability. The magnesium-based S type aerosol fire extinguishing agent can be widely applied to fire extinguishing in such fields as military equipment, airplanes, ships and computers. The magnesium-based S type aerosol fire extinguishing agent is characterized by comprising the components of strontium nitrate, potassium nitrate, magnesium powder, modifying agent and adhesive, wherein the modifying agent comprises urotropin, dicyandiamide, ammonium oxalate, polyvinyl alcohol and monopotassium phosphate.
Description
Technical field:
The present invention relates to the extinguishing chemical in fire-fighting fire extinguishing equipment, particularly relate to a kind of magnesium base S type aerosol extinguishing agent.
Background technology:
Hot-gas sol fire extinguishing agent be mainly divided into K type and two kinds, S type, K type aerosol extinguishing agent is mainly oxidant with potassium nitrate, and S type aerosol extinguishing agent is mainly oxidant with silver nitrate.There is many problems in existing K type extinguishing chemical, such as, generate potassium oxide after sylvite burning, potassium oxide is the material that a kind of hygroscopicity is very strong, can absorb the moisture in air, generates potassium hydroxide, has very strong corrosivity, can cause secondary damage to protected object.S type extinguishing chemical produces in order to the corrosivity improving K type extinguishing chemical, although it well improves the corrosivity of extinguishing chemical, but still there is a lot of problem, such as: ignition temperature high (easily formed secondary harm), extinguishing chemical self sensitivity is high, residual rate is high and combustibility is unstable etc.
Magnesium powder is the fuel agent that a kind of safety is excellent, its combustibility is stablized, burn after residual less, combustion product is environmentally friendly and product magnesia after burning and magnesium carbonate have inhibitory action to flame, but its thermal discharge is high, be not often selected as the fuel agent of extinguishing chemical.Magnesium powder can well improve S type extinguishing chemical, reduces ignition temperature and residual rate, and its combustibility is stablized.
Summary of the invention:
In order to overcome the defect of prior art, the invention provides a kind of magnesium base S type aerosol extinguishing agent, can solve that fire-fighting efficiency is not high, residual rate is high, ignition temperature is high and the problem such as the stable difference of combustibility.The fire extinguishing fields such as military equipment, aircraft, boats and ships and computer can be widely used in.

Embodiment two: the constituent of described magnesium base S type aerosol extinguishing agent, by mass percentage, filling a prescription is:
Compared with embodiment one, the present embodiment two has lower ignition temperature, and more stable when burning.
Embodiment three: the constituent of described magnesium base S type aerosol extinguishing agent, by mass percentage, filling a prescription is:
Compared with embodiment two, the present embodiment three has lower ignition temperature, and more stable when burning, and fire-fighting efficiency is higher.
Embodiment four: the constituent of described magnesium base S type aerosol extinguishing agent, by mass percentage, filling a prescription is:
Described modifier one is the mixture of methenamine and dicyandiamide, its constituent, in the mass percent of magnesium base S type aerosol extinguishing agent is:
Methenamine 1%
Dicyandiamide 1.5%
Described modifier two is the mixture of ammonium oxalate and polyvinyl alcohol, its constituent, in the mass percent of magnesium base S type aerosol extinguishing agent is:
Ammonium oxalate 2%
Polyvinyl alcohol 5%
Compared with embodiment three, the present embodiment four has lower ignition temperature, and more stable when burning, and fire-fighting efficiency is higher, and after burning, solid residue is less.
Be only in sum the preferred embodiment of invention and oneself, be not used for limiting practical range of the present invention.Namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, and all should be technology category of the present invention.
