摘　　要：为了获得安全性能较好的压装高聚物粘结炸药(PBX),以3-硝基-1,2,4-三唑-5-酮(NTO)和奥克托今(HMX)为主体炸药,采用水悬浮法制备了NTO/HMX基压装PBX,测定了NTO在水中的溶解度,考察了水药比、搅拌速度对包覆效果的影响和主炸药粒度对撞击感度的影响,测定了产品的爆速。结果表明:NTO在水中的溶解度较大,在常温下制备,用NTO饱和水溶液代替水作分散介质;最佳工艺条件为:水药比(体积质量比)为1.6∶1,搅拌速度为500 r/min;主炸药粒度细化后产品的撞击感度下降了43%,只有15.3%;产品的爆速为8 200 m/s,达到了理论爆速的95%以上。In order to obtain a pressed fitting PBX that has good safety performance,3-nitro-1,2,4-triazol-5-one（ NTO） and HMX is used as the base explosive to make NTO/HMX based pressed fitting PBX by water slurry method.Solubility of NTO in water has been determined. The influences of the ratio of water and explosive compound,and agitating rate on the coating effect are studied. The effect of particle size of explosive compound on the impact sensitivity is also investigated. The detonation velocity of PBX has been determined. The result indicates that NTO has high solubility in water. At room temperature,the saturated NTO solution can be used to make molding powder. The optimal technical conditions are 1. 6∶ 1 of water and explosive compound ratio（ V / M） and 500 r / min of agitating rate. After refining particle size of NTO and HMX,the impact sensitivity is only 15. 3%,which is decreased by 43%. The detonation velocity of PBX was 8 200 m / s,which is above 95% of theoretical maximum detonation velocity.
