摘要
利用高压蒸汽闪爆处理后的Novel纤维素为原料,经过碱化、醚化、硝化和叠氮化反应,得到了一种新型高能粘合剂——硝化纤维素叠氮甘油醚,并采用元素分析、DSC、FIT红外光谱和X-射线等对其含氮量、结构和性能进行了分析表征。结果表明,新型高能粘合剂同时含有-ONO2和-N3基团,其含氮量可达到15%～21%,结晶性下降,在204℃分解,有较大的放热峰,在丙酮等有机溶剂中溶解性很好。
A kind of new high energetic bonder—nitrocellulose azidonitrate glycidyl ether (NCAGE) for solid propellant was synthesized based on cotton cellulose pretreated by steam explosion. The process of preparing NCAGE included the following steps: (a) alkalization of the treated cellulose; (b) etherification of the alkali cellulose; (c) nitration of the water-soluble cellulose ether; and (d) azidation of nitrocellulose glycidol ether. The nitrogen content, structure and properties of NCAGE were measured and characterized by elementary analysis, DSC, FTIR and X ray Diffraction. The results indicate that the nitrogen content of NCAGE can arrive at 15%～21% duo to the presence of - ONO2 and -N3, and the product can absolutely dissolve in solvents such as acetone, decompose at the temperature of 204℃ and has lower degree of crystallinity compared to original cellulose.
