为了克服二硝酰胺铵(ADN)和异氰酸酯类固化剂不相容的问题,以聚叠氮缩水甘油醚(GAP)/丁二酸二丙炔醇酯(BPS)交联体为包覆材料,通过1,3-偶极加成环化反应对球形ADN颗粒进行了交联固化包覆研究。采用扫描电镜能谱仪(EDS)和动态吸湿性分析法分析了ADN包覆后的表面元素组成和吸湿性,结果表明,与GAP/六亚甲基二异氰酸酯缩二脲固化剂(N-100)交联体相比,GAP/BPS交联体不仅与ADN相容性较好,还可获得较好的包覆效果,包覆后ADN的饱和吸湿率仅为0.78%。
In order to overcome the incompatibility of ammonium dinitramide (ADN) and isocyanate curing agent, the cross-linked polygalactopyranose (GAP) / dipropinol succinate (BPS) The spherical ADN particles were crosslinked and cured by 1,3-dipolar addition cyclization. The elemental composition and hygroscopicity of ADN coated surface were analyzed by scanning electron microscopy (EDS) and dynamic hygroscopicity analysis. The results showed that the surface elemental composition and hygroscopicity of ADN coating were compared with that of GAP / hexamethylene diisocyanate biuret curing agent (N-100 ) Cross-linked body, GAP / BPS cross-linked body not only with ADN better compatibility, but also get a better coating effect, after coating ADN saturated moisture absorption rate was only 0.78%.
