Description
Technical field
The present invention relates to boron powder, more particularly to a kind of boron-based fuel-rich processing method of boron powder.
Background technology
Since nineteen seventies, countries in the world competitively developing solid rocket ramjet technology, research background is related to all kinds of guided missiles such as air-ground, absolutely empty, anti-ship and antiradiation.Boron-based fuel-rich is one of Pinch technology of restriction solid rocket ramjet technology application, is of future generation long-range China（More than 400km）The key technology of the practical Gonna breakthrough first of absolutely empty bullet, antiradiation missile.Boron powder is used as fuel in boron-based fuel-rich and provides energy, but boron powder footpath is small, and surface has B2O3、H3BO3Deng impurity, the technique and combustibility of propellant can be influenceed in engineer applied, solve these problems, the potential of competence exertion boron powder high heating value.
US 3976521 is given with liquefied ammonia as solvent, and ammonium perchlorate is the processing method that covering is coated to boron powder.Pang Wei is waited by force to reduce the B on amorphous boron powder surface2O3、H3BO3Deng impurity, respectively with mannitol, TP, TA and NaOH solution as raw material, Research on Surface Modification is carried out to amorphous boron powder.It was found that boron powder is modified through the surface of different chemical substances, the B element content on boron powder surface is improved.Fan Xuezhong etc. is optimized by orthogonal experiment, the technological parameter that spherical agglomerated boron particles are prepared to solvent evaporated method, have studied the influence of solidification temperature and hardening time to the form, Average Particle Diameters and its distribution of spherical agglomerated boron particles.Also there are following two aspects in engineer applied in domestic and international existing processing method：1）Processing performance to propellant improves not substantially, constrains the charge process of boron-propellant；2）To the combustibility of propellant, burning rate pressure exponent raising effect is especially improved not notable.
The content of the invention
There is obstinate B for the surface of boron powder2O3、H3BO3Deng impurity the characteristics of, using Surface coating and the compounding method of agglomeration granulation, invent a kind of processing method of boron-based fuel-rich boron powder.Present invention aim to address the problem that prior art can not produce boron-based fuel-rich boron powder, there is provided the compounding method of a kind of utilization Surface coating and agglomeration granulation, a kind of processing method for preparing boron-based fuel-rich boron powder is invented.
The present invention adopts the following technical scheme that realization：The surface treatment method of boron powder is comprised the following steps：
Step one, by boron powder soak at room temperature in a solvent, soak 24h, at a temperature of being placed in 50 DEG C dry take out, crush it is standby；
Step 2, covering and ethanol are mixed according to suitable ratio, are stirred at room temperature to solution clarification, the boron powder after solvent soaking is slowly added in solution, stirred, solvent slowly volatilizees, to boron powder it is more dry when, take out sieving, dry for standby；
Step 3, chemical treatments and acetone are dissolved according to a certain percentage, are slowly added to the boron powder of cladding, stirring, solvent slowly volatilizees, to boron powder it is more dry when, take out sieving, dry for standby；
Step 4, agglomeration granulation adhesive and curing agent are added acetone by a certain percentage, stirred to being completely dissolved, be slowly added to chemically treated boron powder, stirred, solvent slowly volatilizees, to boron powder it is more dry when, take out sieving, solidification.
Further, the solvent of the step one is any one in acetone, ethyl acetate.The mass fraction that solvent is used accounts for the 50%-80% of boron silty amount.
Further, the covering of the step 2 be ammonium perchlorate, HMX, hexogen in any one or a few.The mass fraction that described covering is used accounts for the 10%-15% of boron silty amount.Described covering and the mass ratio of ethanol are 1:30.
Further, the chemical treatments of the step 3 are phenylisocyanate, 4, any one or a few in 4 '-methyl diphenylene diisocyanate, PPDI.The mass fraction that described chemical treatments are used accounts for the 1%-2% of boron silty amount.Described chemical treatments and the mass ratio of acetone are 1:50.
Further, the adhesive of the step 4 is end hydroxy butadiene.Described curing agent is any one in 2,4- toluene di-isocyanate(TDI)s, IPDI or two kinds.
Described adhesive is 1 with curing agent mass ratio:1-1:1.5.
The mass fraction that described adhesive and curing agent is used accounts for the 5%-7% of boron silty amount.
Described adhesive and curing agent total amount and the mass ratio of acetone are 1:80
Boron powder after described agglomeration granulation solidifies 7 days at 60 DEG C.
The invention has the advantages that：
（1）, can there is obstinate B by the surface of boron powder by the means such as chemical reaction and isolation using solvent soaking, precipitation cladding and chemically treated composite surface treatment method in the boron-based fuel-rich of the invention processing method of boron powder2O3、H3BO3Influence Deng impurity is preferably minimized.
（2）The boron-based fuel-rich of the invention processing method of boron powder, the boron powder of suitable particle diameter is prepared using agglomerating prilling method, can meet motor charge to Propellant Processing Characteristics demand by size grading.
（3）The boron-based fuel-rich of the invention processing method of boron powder, yield is high, typically more than 95%.
