The present invention relates to a kind of using micro-nano thermite as material cavity liner containing energy, obtained by the raw material mixing compacting of following weight/mass percentage composition：Aluminium powder 15~35%, metal oxide 55~80%, ferrocene 1~5%, binding agent 1~8%, wherein binding agent are the compound system of fluorubber and polystyrene.Cavity liner energy density of the present invention is high, has a safety feature, when explosive drives will not immediate response, but Penetration can occur harsh chemical and react and release high heat, the generation red-hot reaction product of high temperature.The present invention containing can cavity liner can be used with conventional cavity liner matched combined, play it is appropriate expand perforation diameter and the follow-up effect of setting on fire, injured or fragmentation effect with strengthening.
Description
Technical field
The invention belongs to cavity liner technical field, is related to a kind of cavity liner being made up of aluminothermy class energetic material.The present invention
It is described containing can cavity liner not only there is high security feature, and have very high energy density, moderate reaction speed and
Higher mechanical property, it can be applied to efficiently injure field.
Background technology
With the development of modern military industrial technology, all kinds of reactive armor guard technologies have obtained further raising, to broken at present
Selection, structure and the manufacturing process of first bullet cavity liner propose acid test.The jet that traditional inertia property of medicine cover is formed exists
Aftereffect deficiency after penetration target, it is impossible to which enough effective strikes are carried out to enemy's target.Under the premise of this, it is switched on both at home and abroad
The research of active cavity liner (i.e. the cavity liner containing energy).So-called " activity ", the material for referring to manufacture cavity liner is no longer entirely inertia
Metal material, and be utilized in the active material that a large amount of chemical energy can be discharged in Penetration.Traditional cavity liner, such as apply
Most wide copper cover, it is to realize broken first by mechanical force, a perforation can only be formed in plate armour, strike effect is limited.Activity
Cavity liner is then while ensureing that mechanical force breaks first (perforating), moreover it is possible to discharges a large amount of chemical energy to aid in brokenly first, significantly
Increase damage effectiveness (such as effect of setting on fire after increase holes diameter, and broken first etc.).Therefore, Types of Medicine are manufactured with active material
Cover, is a new direction of current cavity liner development, but studies also very limited.
Foreign countries have carried out the research of active cavity liner already, but extremely maintain secrecy, and are only capable of finding US military at present 2001
One meeting paper (E.L. Baker, A.S. Daniels, K.W. Ng, etc. Barnie in year: A Unitary
Demolition Warhead[C]. 19th International Symposium of Ballistics, 7–11 May
2001, Interlaken, Switzerland, 569-574.).The paper reports the unitary of a kind of entitled " Barnie " to contain
Energy cavity liner, the cavity liner are made up of some unknown materials, and play can occur during penetration target for the jet formed
Strong chemical reaction, substantial amounts of heat and gas are generated, produces subsequent explosion effect, and be successfully applied to stone matter and concrete
Target.From the point of view of experiment process and result, the material for manufacturing the cavity liner should be a kind of larger compound material containing energy of density
Material.
The domestic research for active cavity liner starts to walk very late, the document of some common simulations early stage and theoretical calculation, closely
Just there is within 2 years the research on manufacturing and testing on a small quantity.Such as, Zhang Zimin etc. (study by active metal medicine type cover perforating bullet armor-penetrating test
[J] explosives, 2013,42 (4):53-56.) report a kind of formula of active metal medicine type cover perforating bullet, prepare
And armor-penetrating test research, using the mixture of aluminium powder (Al) and nickel powder (Ni) as active component, polytetrafluoroethylene (PTFE) (PTFE) is viscous
Agent is tied, the purpose of increase damage effectiveness is reached using alloying reaction (Al+Ni → AlNi) heat release between Al and Ni.But should
Reaction thermal discharge very little (1.38kJ/g) thermodynamically, chemical reaction free energy it is higher (Δ G at 1000 DEG C=-
101.95kJ/mol), therefore it is not the exothermic reaction of a self- propagating.As can be seen that and inertia cover from its experiment effect
Compare, the raising of its damage effectiveness is simultaneously little, and effect of not setting on fire.Strictly speaking, Al-Ni mixtures can only be referred to as active material
Material, rather than energetic material.In addition, as binding agent the mechanical property of cavity liner can be caused to be deteriorated using PTFE.
Xin Chunliang etc. (active cavity liner beehive-shaped charge bullet damage effect research [J] war industry's journal, 2014,35
(Suppl.2):A kind of active cavity liner 217-220.) is reported, and test it injures performance.Its cavity liner formula is
Al-PTFE systems, the system are a kind of relatively low systems containing energy of heat release, and shortcoming is the small (~2.2g/cm of cavity liner density3), machine
Tool low intensity, formula oxygen balance are not easy to grasp.Particularly polymer P TFE mass fraction reaches 70% in its formula, certainly will incite somebody to action
Have a strong impact on the mechanical property of cavity liner；Also, PTFE powder is a kind of polymer powder, it is difficult production during explosion driving
Raw high intensity jet.In addition, the cavity liner is that blank is made using sintering process, finally it is machined into.Although this method
It is suitable for the shaping of inert powder cavity liner, but is not suitable for the shaping of the cavity liner containing energy, because sintering process is to energetic material
For it is extremely dangerous, be added significantly to prepare danger.
Nanometer aluminium powder is applied to energetic material as high-energy fuel, has been demonstrated that the combustion of energetic material can be significantly improved
Burn performance.It can improve the HRR in condensed phase due to its high rate of heat release, therefore the energetic material containing nanometer aluminium powder
With higher heat flux, cause tens times or even hundreds of times that its combustion intensity is traditional micro materials.Due to nanometer aluminium powder
With larger specific surface area (＞ 50m2/ g), compared with common aluminium powder, the thermal oxidation process of nanometer aluminium powder has low-down
Reaction activity, reacting initial temperature is caused significantly to shift to an earlier date and light a fire easily.For example, traditional bulky grain Al-Fe2O3Thermite
Reaction activity (Ea) it is about 500kJ/mol, reacting initial temperature (T 0 ) it is about 950 DEG C；And the Al- being made up of Al Nanoparticles
Fe2O3ThermiteEa≈ 300kJ/mol,T 0 ≈550℃.Therefore, the granularity of aluminium powder is decreased to nanoscale, in dynamics side
Combustion reaction in face of thermite has the effect of greatly facilitating.But in the data that can be retrieved at present, by nanometer aluminium powder
Apply in shaped charge material that there is not been reported.
The content of the invention
It is an object of the invention to provide a kind of using micro-nano thermite as material cavity liner containing energy, to improve property of medicine cover institute
Aftereffect of the jet of formation after penetration target, effectively strike enough is carried out to enemy's target.
