| 摘 要： | 纤维素甘油醚硝酸酯NGEC是一种改性硝化棉,以NGEC为粘合剂代替NC,采用传统的无溶剂法制备了NGEC基改性双基推进剂。研究了以NGEC为粘合剂的改性双基推进剂的力学、燃烧和弹道性能及燃烧波结构。结果表明,NGEC具有较好的热塑性,NGEC基改性双基推进剂加工性能优良,其低温-40℃延伸率可达相同配方NC基改性双基推进剂的1.5倍以上,其推进剂弹道性能稳定,燃烧性能和燃烧波结构与NC基推进剂相似。因此,NGEC作为含能粘合剂代替NC,可用于改善改性双基推进剂性能的研究。 |

| Abstract: | Nitrate ester of cellulose glycidyl ether(NGEC) is one kind of modified nitrocelluloses.The NGEC-modified double-base propellants were prepared by using traditional solvent-free method.The properties of NGEC modified double base propellant including mechanical,combustion,ballistic and combustion wave structure were investigated.The results show that NGEC has good thermoplastic and NGEC modified double base propellant exhibits a better processing property.Compared with NC-based propellant,NGEC modified double base propellant possesses 1.5 times higher elongation at low temperature(-40 ℃),stable ballistic performance and similar combustion properties and combustion waves structure.So,as an energetic thermoplastic binder instead of NC,NGEC can be used in new modified double base propellant research. |
| Keywords: | modified nitrocellulose the high-solid modified double base propellant mechanical properties combustion performance combustion waves structure |
