摘要:
采用介观动力学(MesoDyn)模拟方法对比研究了增塑剂硝化甘油(NG)、1,5-二叠氮-3-硝基氮杂环戊烷(DIANP)、N-丁基硝氧乙基硝胺(Bu-NENA)、双(2,2-二硝基丙醇)缩甲醛(BDNPF)/双(2,2-二硝基丙醇)缩乙醛(BDNPA)(BDNPF/A,两者质量比为1∶1)与硝化纤维素(NC)共混体系的相结构及其演变过程和影响因素,用扫描电子显微镜对比研究了质量配比为50/50的4种NC/增塑剂共混体系混溶产物的微观形貌。结果表明,与NG相比,DIANP、Bu-NENA和BDNPF/A与NC的混溶性更好,且显微形貌特征与介观动力学模拟结果一致性较好;20℃下,质量配比为30/70的NC/BDNPA/F共混体系和质量配比为70/30、60/40、50/50、40/60和30/70的NC/NG共混体系产生相分离;质量配比为50/50的NC/NG共混体系,NG与NC的混溶性随温度的升高而改善,40℃以上时体系的相分离现象消失。
Abstract:
The phase structures and their evolution processes and affecting factors of blend systems of plasticizers nitroglycerine (NG), 1,5-diazido-3-nitrazapentane (DIANP), N-butyl nitroxyethyl nitramine (Bu-NENA),bis(2,2-dinitropropyl) formal (BDNPF)/bis (2,2-dinitropropyl) formal acetal (BDNPA) (designated as BDNPF/A when the mass ratio of BDNPF/BDNPA is 1:1) and nitrocellulose (NC) respectively were compared and studied by using a mesoscopic dynamics simulation method. The micromorphology of miscible products of four kinds of blend systems with the mass ratio of NC and plasticizer as 50/50 was compared and studied using scanning electron microscope. The results show that compared with plasticizer NG, the plasticizers DIANP, Bu-NENA and BDNPF/A exhibit better miscibility with NC, and their micromorphology characteristics are in good agreement with the mesoscopic dynamics simulation results. At 20℃, the phase separation for NC/BDNPA/F blend system with the mass ratio as 30/70 and NC/NG blend systems with the mass ratio as 70/30, 60/40, 50/50, 40/60 and 30/70 occurs. For the NC/NG blend system with the mass ratio as 50/50, the miscibility of NG and NC improves with increasing the temperature, and the phase separation phenomenon of the system disappeared at more than 40℃.
