Description
Technical field
The present invention relates to extinguishing chemical, more particularly to a kind of novel hot aerosol extinguishing agent.
Background technology
Hot-gas sol fire extinguishing agent is the organoselenocyanate and inertia by endothermic decomposition cooling effect, gas phase and solid phase
Gas dilution oxygen effect etc. reaches fire extinguishing purpose.Containing about 40% solid constituent and 60% indifferent gas in its combustion product
Body component, in confined space based on the organoselenocyanate of 40% fire extinguishing component particles in unit mass, 60% inertia
Put out a fire supplemented by gas dilution effect, its efficiency is higher.
Presently commercially available K-type aerosol extinguishing agent, which has product, huge corrosivity, spout easily quilt to electronic metal part
The problem of blocking, constrain its application.It is slow jet velocity to be present in commercially available S type hot-gas sol fire extinguishing agents, and reaction is incomplete,
Fire extinguishing effectiveness is low, after medicament stores for a long time, the problems such as lighting rate can not be effectively ensured.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of novel hot aerosol extinguishing agent, the present invention

3 parts, methenamine 2-3 parts, sodium oxalate 2-3 parts, conditioning agent 1-2 parts.
Preferably, its raw material includes by weight：Modified oxidized magnesium 42-48 parts, sodium nitrate 21-24 parts, nitroguanidine 16-19
Part, potassium picrate 12.5-13.5 parts, wool powder 1.5-2.5 parts, castor oil 2.5-3.5 parts, shellac 2.2-2.8 parts, methenamine
2.2-2.8 parts, sodium oxalate 2.1-2.7 parts, conditioning agent 1.2-1.8 parts.
Preferably, the weight ratio of the sodium oxalate and conditioning agent is 2.5-2.6：1.5-1.7.
Preferably, the preparation method of the modified oxidized magnesium is：Magnesia and atlapulgite are mixed, grind 10-
20min, methyl-silicone oil is added, be warming up to 40-50 DEG C, insulated and stirred 50-60min, vacuum drying, cross 400-500 mesh sieves, produce
Modified oxidized magnesium.
Preferably, the conditioning agent includes aluminium carbonate, magnesium carbonate and carbon dust.
Preferably, the magnesia, atlapulgite, the weight ratio of methyl-silicone oil are 1：0.2-0.5：2-3.
Preferably, the aluminium carbonate, magnesium carbonate, the weight ratio of carbon dust are 1-2：1-3：1-3.
The preparation technology of the novel hot aerosol extinguishing agent of the present invention can be made according to the conventional fabrication process in place field,
Each raw material is mixed according to the parts by weight and is molded.
Using modified oxidized magnesium and sodium nitrate as oxidant in the hot-gas sol fire extinguishing agent of the present invention, wherein, with active white
Soil and methyl-silicone oil are modified to magnesia, and both, which coordinate, is collectively forming the hydrophobic field of superposition, and collaboration keeps the hydrophobic of magnesia
Moisture resistance, the defects of making up the magnesia easy moisture absorption, modified magnesia and sodium nitrate interworking, have that oxygen content is high, is not easy to inhale
Tide, the characteristics of product is nontoxic, while make obtained hot-gas sol fire extinguishing agent that there is relatively low friction sensitivity and impact sensitivity；With nitre
Base guanidine and potassium picrate as fuel agent, wherein, potassium picrate has preferable heat endurance, compatibility and a stability, and fires
It is few to burn rapid residual, adds wool powder, and its potassium element contained can play fire extinguishing function, add wool powder, can be to hardship
Sour potassium is modified, and reduces the ignition temperature of potassium picrate, after nitroguanidine interworking so that hot-gas sol fire extinguishing agent has excellent
Different fire extinguishing effect；Castor oil, shellac, methenamine, sodium oxalate are added, with sodium nitrate mating reaction, further reduces burning
Temperature, improve combustion stability, fire extinguishing effectiveness and the stability of hot-gas sol fire extinguishing agent.
