Preperation Of Nano-based Composite Energetic Materials And Knock Radiation Testing Technology

Based on orthogonal design theory,use of chemical liquid precipitation meth- od La2O3/CNTs nanocomposite particles,Fourier transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),complexometric titration were characterized。Testing the luminous intensity and spectral images of different appendages pyrotechnic formulations,using thermal analysis method for thermal effects of different additions affect perchlorate decomposition。The results showed that the optimal conditions for the preparation of La2O3/CNTs nano composite particles for carbon nanotubes and lanthanum oxide mass ratio of 1: 0.08,and speed to 1300r/min, the bath temperature is 40℃,the calcination temperature of 700 ℃. By Fourier transform infrared analysis and X-ray diffraction analysis of lanthanum oxide particles can be obtained in a carbon nanotube surface load,diameter of 45.9nm. By complexation titration analysis,we can see lanthanum oxide loading on carbon nanotubes is 62%.La2O3/luminous intensity of CNTs-Al-KCl O4 formulations containing nanocomposite particles than single nano additives La2O3-Al-KCl O4 recipes and CNTs-Al-KCl O4 recipe, the luminous intensity can reach 379.933 lx,by thermal analysis catalytic effect means the final results nanocomposite particles La2O3/CNTs is better than lanthanum oxide nanoparticles with purified carbon nanotubes.
