Abstract
The submicron CL-20 was prepared by solvent-nonsolvent method with different surfactants, and the influence factors about various kinds, quality and injecting styles of surfactants were analyzed. Results show that the uniform and block-like CL-20 with 1 μm, 2 μm are obtained using 2 g raw materials CL-20 with 3.5 mL 2% polyvinyl alcohol (PV), and with 6.5 mL 5% polyoxyethylene ether (PT) respectively. The particle with 1 μm and elliptoid uniform and narrow particle-size distribution are obtained by watering pot injecting method with 6.5 mL 5% PT. CL-20 has higher heat sensitivity and is still ε polymorph after fine.
