摘要
为阐述新一代纤维素基含能黏合剂的研究和发展前景,针对纤维素、硝化纤维素的结构和性能特点,指出由于其大分子链刚性强,使得NC火药普遍存在能量低、制品低温脆、高温软等不足,通过分析近期研究成果和国内外相关资料,综述了纤维素基新型高性能黏合剂研发必要性、化学结构、现状及其应用方向,认为纤维素接枝侧长链增塑后、再在羟基上叠氮化和硝化,作为高性能黏合剂,可极大地提高推进剂的低特征信号、高能和钝感等综合性能。
In order to expatiate on the foreground of the new generation energetic bonder research and development, a shortcoming of low energy, brittleness at low temperature and turning soft at high temperature of the NC powder caused by the rigidity of the NC molecular chain is presented. With the help of the recent research with the internal and overseas status, the necessity of developing the new generation cellulose-based and high performance energetic bonder, the chemical structure, actuality and applied direction of the new energetic bond are summarized. The cellulose plasticized by long carbon chain at the flank, azidonitrified and nitrified at the hydroxyl as a high performance bonder can enhance the synthetical performances of the propellant, e.g. high energy, desenisitivity and low signal.
