Description
Technical field
The present invention relates to a kind of cryogenic gas propellant, with aerogenesis temperature is low, aeration speed is fast, gas forming amount is big, solid
The features such as residue content is low, it disclosure satisfy that buffering pneumatic cushion and the utricule of other special purposes, it can also be used to extraordinary energy storage device
Fast aeration.
Background technology
Gas-forming agent burning produces a large amount of gases, according to the difference for producing gas property, available for different purposes.Example
Pure oxygen can be produced during the gas-forming agent burning being such as made using potassium manganate, available for the urgency under anaerobic condition
Rescue；The gas-forming agent being made using nitrine class material or some non-nitrine class materials has that aeration speed is fast, gas peace
The characteristics of Atoxic, available for safe automobile air bag；Some gas-forming agents, such as gas generator propellant, there are 800 DEG C~1400 DEG C
Ignition temperature, the features such as solid residue content is low, burn rate is low, flameholding, chemical energy can be converted into mechanical or electrical energy,
Gesture stability available for guided missile etc..
Automobile airbag gas propellant and armament systems gas generator propellant are because of combustion temperature height, it is necessary to pass through woven wire
Deng can just obtain a small amount of low temperature combustion gas after cooling measure, cause generator volume weight to increase considerably, large scale can not be realized
The fast aeration of closed utricule.
The content of the invention
It is an object of the invention to provide a kind of gas-forming agent, gas forming amount is big, and residue content is few, and gas-filling temperature is low.Adopt
The gas generator made of the propellant is simple in construction, is not required to Physical temperature-lowering（Wire netting etc.）Combustion gas can be poured to closed capsule
Body.
The present invention also aims to provide the preparation method of above-mentioned cryogenic gas propellant.
The technology of the present invention solution：Cryogenic gas propellant, include following component and content（Mass percent）：
Guanidine nitrate：40%~60%；
Ignition temperature conditioning agent agent：25~55%；
Combustion velocity regulator：3%~15%；
Adhesive：0.5%~3%.
Each component optimum ratio of the present invention is：
Guanidine nitrate：45%~50%；
Ignition temperature conditioning agent agent：40~48%；
Combustion velocity regulator：5%~10%；
Adhesive：1%~3%.
Ignition temperature conditioning agent of the present invention is oxamide, ammonium oxalate, ammonium sulfate, the hydrazine of oxalyl two, the formyl of azo two
One or more combination in ammonium.
Combustion velocity regulator of the present invention is double tetrazolium ammonium salts, zinc oxide, one kind in copper and iron oxide or several
Kind combination.
Adhesive of the present invention is the one or more combination in clay, paraffin, cellulose, modified cellulose.
The preparation method of cryogenic gas propellant of the present invention, component mixing is uniformly dispersed composition is made,
Using press devices such as tablet press machine, forging presses, combinations of the above thing is made to the entity of some strength through tabletting or be granulated.
The entity is the tablet that thickness is 1 ~ 8mm or cylinder or the entity of the interior any shape for having a blast tube, or
Tablet, spheric granules, the particle of irregular shape, the regular or irregular entity of cylinder or cone.
The component is mixed to be uniformly dispersed by the present invention is made composition, is set using wet granulation or dry granulation or ball blast
It is standby, by spherical made of the composition described in claim 1 or irregular entity.
The advantages of present invention is compared with other gas-forming agents are as follows.
(1) compared with gas generating agent for automobile safe gasbag, the present invention has gas forming amount big, fires the low advantage of temperature, uses
The gas generator of technology manufacture is simple in construction, without that can pour air bag using Physical temperature-lowering means such as wires.Although
Due to gas ingredients（Contain nitrogen oxides and carbon monoxide etc.）Limited, the present invention is not suitable for safe automobile air bag, but can be with
Sealing utricule to all size carries out fast aeration, realizes special purpose, and gas generating agent for automobile safe gasbag is because of combustion
Wen Gao, the low temperature combustion gas by obtaining few tolerance after wire Physical temperature-lowering is only capable of, the fast aeration to air vesicle can not be realized.
The present invention can be applied to expedient float bridge after quickly pouring utricule, deep water is salvaged, high-altitude soft landing（Such as Mars soft landing）, lifesaving
Ship, decoy, gas cylinder accumulator etc..
（2）Compared with the conventional gas generator propellant of Aeronautics and Astronautics, missile armament, the present invention has warm low, the aeration speed of combustion
The features such as fast.Combustion gas caused by conventional gas generator propellant can not be applied to the inflation of extraordinary air bag at 800 DEG C~1400 DEG C.
During to energy storage inflating gas cylinder, because initial gas temperature is high, drop of pressure is more during cooling, and practical use is little.It is and of the invention
Not only aeration speed is fast, and combustion temperature is low, and temperature decline is limited, and pressure is relatively stable.
Aerogenesis temperature of the present invention is low, and ignition temperature is no more than 600 DEG C, and gas temperature is no more than 250 DEG C after pouring utricule（Phase
To pressure 25kPa）, the utricule that the material such as aramid fiber makes can bear；Aeration speed is fast, and inflationtime can in 0.2s~1s
Adjust；Gas forming amount is big, solid residue content is low, and solid constituent is decomposed into micro-molecular gas, and carbon residue content is few, disclosure satisfy that
The utricule of buffering pneumatic cushion and other special purposes, it can also be used to the fast aeration of extraordinary energy storage device.
