Description
Technical field
The invention belongs to the energetic material preparation field, relate to a kind of low mechanical sensitivity explosive and preparation method thereof, be specifically related to a kind of graphene oxide (GO) and sensitive explosive of utilizing and be mixed with low mechanical sensitivity method of filling explosive.
Background technology
Nitro-amine compound explosive such as octogen (HMX), Cyclotrimethylene trinitramine (RDX) and hexanitro-hexaazaisopen wootz alkyl (CL-20) are to use at present high energy master explosive material very widely, have that energy density is big, premium propertiess such as good heat resistance, detonation are stable, explosion velocity height.They are bringing into play the effect that can not be substituted at aspects such as national defense and military.Yet because such explosive has high explosion velocity, detonation pressure, quick-fried heat and big power and brisance, this gives safety in production, stores the many problems of having brought of transporting.For this reason, domestic and international many scientific research personnel handle feeling immediately of such explosive and have carried out research deeply and widely.Median size, purity, pattern, slickness and the lattice defect etc. of finding explosive crystal as people such as Antoine have very big relation with its sensitivity, and this shows the purpose that explosive can be realized insensitiveness through good crystallization and post-processing technology.In addition, adding inert material (as paraffin, stearic acid, high molecular polymer, carbon material etc.) also is a kind of efficient ways that reduces explosive sensitivity at present.Wherein carbon material receives many scientific research persons' concern again because it is cheap.As Manning(USP6524706,2003) investigated the interpolation of Graphite Powder 99 to the influence of sensitive explosive sensitivity.Experimental result shows that the interpolation of Graphite Powder 99 makes the explosive impact sensitivity reduce by 40%.People such as Peng (Propellants Explos.Pyrotech.2008,33) at first utilize recrystallization method to prepare two kinds of new soccerballene (C60-2, C60-3), adopt the method for milling respectively they and the commercial soccerballene of buying (C60-1) to be added in the HMX explosive then.Test result shows, the 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 and not obvious falls.People such as Chi Yu (GF-A0092102G, 2006) adopt the method for mechanically mixing that the carbon nanotube (CNTs) of different ratios is sneaked among the explosive HMX.Under the same test condition, compare 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%, 28% from 100%; Friction sensitivity drops to 76%, 72% from 100%.Above result of study shows, although these present carbon materials such as graphite, C60 and CNTs can make the mechanical sensitivity of explosive decrease, effect all is not very desirable.In addition, these carbon materials itself are not energetic materials, and their adding certainly will influence the energy that explosive discharges.
Graphene oxide (GO) is as the novel carbon nanomaterial 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 of feeling agent self as explosive immediately simultaneously.At first, it is the unsettled material of a kind of high-energy, and its exothermic maximum amount can reach 6～8kJ/g, and scientific research person has thought it a kind of energetic material at present.So using it for the energetic material field will more have superiority than other carbon materials.Its two, on the graphene oxide surface and marginal distribution groups such as abundant carboxyl, epoxy group(ing), hydroxyl and carbonyl are arranged, this makes GO sheet interlayer Van der Waals force die down, lamella is easy to slide, and has reduced the possibility that focus emerges.Its three, GO is regarded as a kind of " soft " material because of the characteristic that has shown similar and polymkeric substance, gel and film.So when external force acted on sensitive explosive, " soft material " GO tended to make bump to obtain buffering, simultaneously its easy deformation flows, increase with develop in contacting of focus and absorbing heat, be conducive to stop development and the propagation of focus.
