Description
Technical field
The invention belongs to energetic material preparation field, relate to a kind of low mechanical sensitivity explosive and preparation method thereof, be specifically related to one and utilize graphene oxide (GO) and sensitive explosive to be mixed with the method for low mechanical sensitivity explosive.
Background technology
Nitro-amine compound explosive is apply the main explosive material of high energy very widely at present as octogen (HMX), Cyclotrimethylene trinitramine (RDX) and Hexanitrohexaazaisowurtzitane (CL-20), has the premium propertiess such as energy density is large, good heat resistance, detonation are stable, explosion velocity is high.They play the effect that can not be substituted in national defense and military etc.But because such explosive has high explosion velocity, detonation pressure, quick-fried heat and large power and brisance, this gives safety in production, storage transport brings many problems.For this reason, the feel process of domestic and international many scientific research personnel to such explosive has been carried out deeply studying widely.As the people such as Antoine find the median size of explosive crystal, purity, pattern, slickness and lattice defect etc. have very large relation with its sensitivity, this shows that explosive can realize the object of insensitiveness through good crystallization and post-processing technology.In addition, adding inert material (as paraffin, stearic acid, high molecular polymer, carbon material etc.) is also the effective method of one reducing explosive sensitivity at present.Wherein carbon material receives again the concern of many scientific research persons because it is cheap.As Manning(USP6524706,2003) investigate the interpolation of Graphite Powder 99 to the impact of sensitive explosive sensitivity.Experimental result shows, the interpolation of Graphite Powder 99 makes Shock Sensitivities of Condensed Explosives reduce 40%.The people such as Peng (PropellantsExplos.Pyrotech.2008,33) recrystallization method is first utilized to prepare two kinds of new soccerballene (C60-2, C60-3), the method for milling then is adopted to be added in HMX explosive by the soccerballene (C60-1) that they and business are bought respectively.Test result shows, adding of C60-3 can make the impact sensitivity of HMX and friction sensitivity drop to 70%, 60% from 100% respectively, but C60-1 and C60-2 sense effect not obvious is fallen.The people such as Chi Yu (GF-A0092102G, 2006) adopt the method for mechanically mixing to be mixed in explosive HMX by the carbon nanotube (CNTs) of different ratios.Under same test condition, compared with HMX, the rate of explosion of pyrotechnic composition HMX/CNTs obviously reduces.Along with content of carbon nanotubes increases to 5.0wt% from 1.0wt%, impact sensitivity is reduced to 72% from 100%, and 28%; Friction sensitivity drops to 76% from 100%, and 72%.Above result of study shows, although these current carbon materials such as graphite, C60 and CNTs can make the mechanical sensitivity of explosive decrease, effect is not all very desirable.In addition, these carbon materials itself are not energetic materials, they add the energy that certainly will affect explosive and discharge.
Graphene oxide (GO) is as the Novel Carbon Nanomaterials of discovered in recent years.It not only possesses the fundamental property that other carbon materials have, and it also shows many excellent specific properties feeling agent self as explosive immediately simultaneously.First, it is a kind of material of high-energy instability, and its exothermic maximum amount can reach 6 ~ 8kJ/g, and scientific research person has been thought a kind of energetic material at present.Therefore use it for energetic material field will advantageously than other carbon materials.Its two, have the groups such as abundant carboxyl, epoxy group(ing), hydroxyl and carbonyl in surface of graphene oxide and marginal distribution, this makes GO sheet interlayer Van der Waals force die down, lamella be easy to slide, decrease the possibility that focus is emerged.It three, GO is similarly regarded as one " soft " material with the characteristic of polymkeric substance, gel and film because showing.Therefore when External Force Acting is in sensitive explosive, " soft material " GO tends to make shock be cushioned, simultaneously its easy Deformation Flow, increases and the contact of focus in development and absorbing heat, is conducive to the development and the propagation that stop focus.
