固体推进剂中填料的聚合物包覆

Polymeric-based Cover of the Filler in Solid Propellants

综述了聚合物包覆填料颗粒表面的方法，介绍了一些包覆颗粒的表征手段，提出采用聚合物材料包覆固体颗粒，可提高与粘结剂的界面结合性能，避免脱湿现象，满足推进剂的使用要求。

The particle of the solid fillers have extremely influence on mechanical properties, inflammable and impact sensitivity. The treatment on the surface of the fillers are very important. Therefore, the methods covered on the surface of the fillers by polymers are viewed in this paper and some characteristic methods are also introduced. It is put forword that the polymeric materials covering on the solid particles can raise the surface-bonding energy with binder and avoid dehumidity, which is satisfied for the application of the propellants.
