根据表面和界面化学原理,应用动态接触角测量仪和表面-界而张力仪测试了少烟NEPE推进剂的黏合剂体系(PNT)、填料(HMX、AP和Al粉)和键合剂的表面和界面性能.结果表明,填料(HMX、AP和Al粉)与黏合剂体系(PNT)的界面张力(γsl)大小顺序为:γAl/PNT＜γAP/PNT＜γHMX/PNT,填料与黏合剂体系的黏附功(Wa)大小顺序为:Wa(Al/PNT)＞Wa(HMX/PNT)＞Wa(AP/PNT);键合剂能够自发吸附和分散在推进剂的填料(HMX、AP和Al粉)表面和黏合剂体系中;在推进剂制备过程中,键合剂吸附于填料表面形成的界面能够稳定保持在黏合剂体系中;键合剂能明显提高推进剂的强度和模量,改善填料颗粒与黏合剂体系的界面粘结性能,这与表面性能测试结果一致.

The surface and interracial properties of the binder system, solid particles (including HMX, AP and Al) and bonding agents of low smoke NEPE propellant were studied by means of the dynamic contact angle meter and tensiometer on the principles of surface and interfaeial chemistry. The results indicated that the interfacial tensions (γsl) between the particles (HMX, AP and Al) and binder system (PNT) increase in the order γAl/PNT＜γAP/PNT＜γHMX/PNT and the adhesions (Wa) between them are decrease in the order Wa(Al/PNT)＞Wa(HMX/PNT)＞Wa(AP/PNT). It was found that the bonding agents of the propellant could bond on the surfaces of the solid particles (HMX, AP and Al) and disperse in the binder system automatically. The interfaces between the bonding agent and the particles could be maintained in the binder system during the mixing process of the propellant. It was experimentally shown that the tensile strength and initial modulus of the propellant are increased and bonding strength between the particles and the binder system of the propellant are improved, these are in agreement with the results of the surface and interracial properties measurement.
