采用低温抗冲强度、高温抗压强度及延伸率试验方法 ,对低易损发射药配方用惰性粘结剂与力学性能的关系进行了探索试验研究。经试验研究 ,发现醋丁纤维素较其它惰性粘结剂对低易损发射药力学性能的贡献优越。同时对不同规格醋丁纤维素特性进行了试验研究 ,提出 CAB- Ger可作为该发射药配方的基础粘结剂 ,进一步进行性能改善研究 Low temperature impact strength, high temperature compressive strength and elongation test methods were used to explore the relationship between inert binder and mechanical properties of low vulnerability propellant formulations. The experimental study found that vinegar cellulose than other inert binders on the performance of low-loss propellant contributes superior mechanical properties. At the same time, the properties of cellulose acetate with different specifications were tested and studied. It was suggested that CAB-Ger could be used as the basic binder for the propellant formulation and further study on the performance improvement
