摘要
Abstract
In view of the high friction sensitivity of DAP-4,DAP-4/MW composites were prepared by in-situ coating with microcrystalline wax(MW)in a non-aqueous solvent.The morphology and structure of DAP-4 before and after coating were characterized,the thermal decomposition behavior of DAP-4/MW composites was analyzed,and the sensitivity properties were tested.The results show that MW can be well coated on the surface of DAP-4;The initial thermal decomposition temperature of DAP-4 was advanced by the in-situ coating of MW.When the content of MW increased from 1%to 5%,the decomposition temperature of DAP-4 decreased at different heating rates,and the nergy of activation(Ea)decreased first and then increased.A small amount of MW could reduce the Ea of DAP-4;When the content of MW was 5%,the friction sensitivity(20%)and impact sensitivity(0)of DAP-4/MW5%were significantly lower than the friction sensitivity(100%)and impact sensitivity(15%)of DAP-4.The in-situ coating of microcrystalline wax could effectively improve the safety of DAP-4.关键词
