为解决水悬浮分散包覆工艺制备超细 A5传爆药时存在撞击感度高、制备工艺流程长、超细 RDX 团聚等问题，采用溶剂蒸发法制备工艺，以硬脂酸（ SA）为钝感包覆剂、无水乙醇为溶剂和悬浮剂制备了超细 A5传爆药。对两种工艺制备的样品进行了扫描电镜观察、撞击感度测试和 SA含量测定。结果表明，溶剂蒸发法制备的超细 A5传爆药包覆更均匀，粒径为2．17～10．72μm。与水悬浮分散包覆工艺所得超细 A5传爆药相比，溶剂蒸发法工艺所得超细 A5传爆药撞击感度的特性落高由18．62 cm 提高到32．69 cm，SA的损失率由0．120％减少为0．046％，显示感度低和成分控制更准确。

To solve the problem of high impact sensitivity,long preparation technological process and agglomerate of superfine RDX etc. existed during preparation of superfine A5 booster explosive by aqueous suspension coating technology,superfine A5 booster explosive was prepared with the solvent evaporation technology using stearic acid( SA)as insensitive agent,absolute ethyl alcohol as solvent and dispersant. The scanning electron microscope( SEM)observation,impact sensitivity test and SA content de-termination to samples prepared by two kinds of processes were performed. Results show that the superfine A5 booster explosive is coated more evenly,its particle size is 2. 17 ~10. 72 μm. Compared with superfine A5 booster explosive obtained by an aqueous suspension coating technology,the characteristic drop height of impact sensitivity of superfine A5 booster explosive obtained by the solvent evaporation technology increases from 18 . 62 cm to 32 . 69 cm and loss rate of SA decreases from 0 . 120% to 0 . 046%, which showing a low sensitive and more exactly component controlling.
