低易损发射药配方用粘结剂与力学性能关系探索研究

Study on the relation of the Mechanical Properties with the Inert Binders of LOVA Propellants

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 。

The relation of the mechanical properties with the inert binders of LOVA propell ants was studied by the experiments of their impact strength at low temperature, their compression strength and tensile rate at high temperature. The results sh ow that acetate-butyrate cellulose makes more contribution to the mechanical pr operties of LOVA propellants than the others. By the tests on the characteristic s of different types of acetate-butyrate cellulose, CAB-Ger can be used the ba sic binder of LOVA propellants for further property improvement studies.
