Abstract
RDX was coated with hyantoin/triazines composite bonding agent and the effects of the processing parameters, including reaction time, reaction temperature and bonding agent mass on the coating degree were studied by means of water-solution suspending method in the L9(34) orthogonal experiment. The coated RDX was characterized by X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and impact sensitivity (H50). The optimum conditions are as follows: 10.0 g RDX, reaction time 90 min, reaction temperature 50°C, 0.3 g composite bonding agent (CBA), and stirring speed 700 r·min-1. Accordingly, coating degree is up to 87%. It is found that surface of the coated RDX is covered by clear film with a thickness of about 0.2 μm. In FTIR spectra, NO2 group absorption peak has a 22 cm-1 red shift to 1510 cm-1 and the absorption band widened. Thermal decomposition peak temperature is enhanced 0.4°C. The characteristic height of impact sensitivity (H50) is increased by 4.5 cm.
