单基包覆火药界面粘结强度研究

该文提出了一种改善单基包覆火药界面粘结强度的方法，其工艺过程如下：（１）将单基火药吸收增塑剂进行表面预处理；（２０进行包覆，制备了用增塑剂ＮＧ和ＤＢＰ进行表面预处理的２种单基包覆火药，与直接包覆的单克包覆火药作对比，进行老化和落锤冲击试验，测试其界面粘结强度。

Study on the Interfacial Bonding Strength of Coated Single base Propellant

This paper introduces a method for improving the interfacial bonding strength of coated single base propellant grains.The procedure is as follows: (1) the single base propellant grains are presurfaced by absorbing the plasticizer,(2) coated,and in contrast to the coated single base propellant by the direct coated process,two coated single base propellants presurfaced by NG or DBP are prepared,then aged and measured the interfacial bording strength with the fallhammer test.The effect of the conditions such as plasticizer,aging time and temperature on the interfacial bonding strength of coated single base propellant is discussed.Experiments show that the interfacial bonding strength of coated single base propellant presurfaced by plasticizer NG can be improved obviously.
