Title Research on modified of Hydrazinium Nitroformate by coated method
Abstract
In order to improve some properties of HNF, HNF was coated with 2%, 3% and 5% of polyvinyl alcohol, pentaerythritol stearic acid ester, 12-hydroxystearic acid and 3%, 4% and 5% of TNT by use of coating technology of liquid phase separation and recrystallization. Then uncoated and coated HNF were characterized by infrared spectrometer (FTIR), differential scanning calorimetry(DSC), thermogravimetric analysis (TG) and scanning electron microscopy (SEM) .
The results show that the thermal decomposition peak temperature of the second stage of coated HNF increased, which was coated with 2%, 3%, 4% of polyvinyl alcohol and pentaerythritol stearic acid ester and 3%, 4% and 5% of TNT. Meanwhile, the thermal decomposition peak temperature of the first stage of HNF coated with 2%, 3% and 5% of 12-hydroxystearic acid raised slightly. In addition, the amount of decomposition residue of coated HNF rises more or less, which was coated with 2% and 4% of polyvinyl alcohol, 3% and 4% of pentaerythritol stearic acid ester, 3% of 12-hydroxystearic acid, and 3% of TNT. The result of SEM demonstrated that neat HNF was well-shaped, while the particle shape of coated HNF was irregular, and surface of HNF was coated with above coated agents.
