三基发射药半溶剂法间断捏合加料方式对工艺及成品性能的影响

Effect of Feeding Ways of Intermittent Kneading with Semi-solvent Method on the Technology and Performance of Finished Product of Triple Base Propellant

对三基发射药半溶剂法间断捏合不同加料方式的工艺稳定性、力学性能及显微结构电镜(SEM)照片进行了研究,结果表明:加入固体填料硝基胍(NQ)和溶剂,使NQ被溶剂均匀、充分润湿后再加入粘结剂双基药片的加料方式工艺最稳定,其力学性能、显微结构最佳,同时分析了捏合过程工艺不稳定及成品性能较差的原因。

An investigation was made on the technological stability of different feeding ways of intermittent kneading with semi-solvent method for triple base propellants, on their mechanical properties and on the photographs of microstructure electron microscope (SEM). The results show that the loading way of feeding nitroguanidine(NQ)filler and solvent at first to disperse nitroguanidine uniformly and wet it sufficiently in solvent, then adding binder of double base powder flakes is the most stable technology process, and the finished product has an optimized mechanical properties and microstructure. The cause of instability of kneading process and bad performance of finished product are also discussed.
