Description
Technical field
The present invention relates to special fuel product scope, more particularly, to a kind of low temperature gas-forming agent and its preparation side
Method.
Background technology
There is hydrogen peroxide high density specific impulse (high-energy), environmental protection, normal temperature can store, easy-to-operate, can be single
Constituent element decompose and can spontaneous combustion the advantages of, it is extremely widely applied in industrial circles such as Aero-Space, national defence.Hydrogen peroxide
There is following significant good characteristic as liquid propellant：(1) density and density ratio are leapt high；(2) double groups be can not only be used for
The oxidant of first propellant, can be used as SP again.Hydrogen peroxide pushes away also many advantages as special fuel, such as
Ground can be stored, vapour pressure is low, wherein most prominent advantage is nontoxic pollution-free, be conducive to ensureing aircraft operation personnel life
Life safety, it is easy to operate and use, be spacecraft etc. reuse in cleaning, safeguard create advantage, reduce operation
Expense, shortens and reuses Maintenance Demand Time, can reach the purpose quickly reused, and current each state is all deeply opening
Open up hydrogen peroxide, the research of peroxide motor.
Due to the energy density of high-strength hydrogen peroxide it is big and active high the characteristics of, can when running into impurity or dealing with improperly
It can explode, at home and abroad once occur security incident caused by multiple hydrogen peroxide, except large-scale can sternly be supervised
, structure can pay outside the professional machine of Aero-Space of sky high cost, the high-strength hydrogen peroxide that energy density is big and activity is high is simultaneously
Be not suitable for robot, rehabilitation medicine equipment, game station, gas generating unit, energy generating apparatus etc. close to the general of personnel
Application scenario, is that must capture hydrogen peroxide to decompose that to produce the safety that height temperate zone comes hidden to the successful application prerequisite of the occasion
Suffer from problem, such as 90% hydrogen peroxide decomposition temperature is 850 DEG C, and 85% hydrogen peroxide decomposition temperature is 630 DEG C, easily causes personnel
Injury, the inferior position of heat radiation influence and material tolerance limit extensive use, take Insulation will increase system weight and
Complexity, makes its advantage not embodied, the problems such as liquid cooling such as directly adding water and will bring ignition difficulties, therefore with mistake
Hydrogen oxide is that low temperature gas-forming agent that matrix adds carbon dioxide and preparation method thereof has realistic meaning and its advance.
The content of the invention
The purpose of the present invention is exactly to provide a kind of low temperature gas-forming agent and its preparation side to solve the above problems
Method.
The purpose of the present invention is achieved through the following technical solutions：
A kind of low temperature gas-forming agent, including following component and weight percent content：
A. hydrogen peroxide 25~90%；
B. water 3~40%；
C. carbon dioxide 5~50%.
Described low temperature gas-forming agent decomposition temperature declines 50 DEG C~200 DEG C than prior art.
The preparation method of described low temperature gas-forming agent is：Water is added into hydrogen peroxide by matching, two are added
Carbonoxide is pressurized, and carbon dioxide generates carbonic acid with water, reduces pH value, cools, and is stirred and is obtained purpose production
Thing, temperature is -30~30 DEG C during preparation, and pressure is 1~10Mpa.Mixture is stirred, and the rotating speed of stirring is 10~8000
Rev/min, mixing time is 60~200 minutes.
The present invention is pressurized by being passed through carbon dioxide in aqueous hydrogen peroxide solution, in high pressure system, titanium dioxide
Carbon generates carbonic acid, pH value reduction with water.The present invention reaches heat absorption by controlling hydrogen peroxide, water and the ratio of carbon dioxide
Balanced with heat release, hydrogen peroxide is decomposed into oxygen and water in the presence of catalyst or igniting, and carbon dioxide can absorb
The heat that hydrogen oxide is produced when decomposing, reduces temperature；In addition the gas-forming agent also have low temperature adaptability is good, corrosivity is small,
Combustion gas cleaning non-scaling is not the advantages of carbon distribution, production process are generated without hazardous waste.
Compared with prior art, because present invention employs rational carbon dioxide proportioning, the decomposition (burning) of the product
Temperature reduces by 50~200 DEG C than the decomposition temperature of single aqueous hydrogen peroxide solution, under equal conditions considerably reduces one
As application scenario hydrogen peroxide decompose the potential safety hazards such as the personnel's injury and heat radiation influence that produce that height temperate zone comes, improve material
Tolerance.Due to reducing pH value, stability improves more than 0.5% under similarity condition, is conducive to the extension of shelf-life.Together
When reduce Insulation requirement, using the liquid cooling of addition water etc., do not increase igniting difficulty.
