Study on Properties of Energetic Plasticizer Modified Double‐Base
To improve the low-temperature mechanical properties of double-base propellants, the effects of three energetic plasticizers (geminal dinitro aldehyde acetal plasticizer, azido-terminated glycidyl azide polymer, and ester-terminated glycidyl azide polymer) on the low-temperature mechanical properties of nitrocellulose (NC)/nitroglycerin (NG)
- What is azido plasticizer?
- Azido plasticizer, a type of energetic plasticizer, possesses excellent thermal stability and low glass transition temperature. However, the incorporation of a single azido group can lead to issues such as decreased oxygen balance and reduced density. In recent years, novel azido plasticizers containing various energetic groups have been developed.
- Which reagent is used to introduce azido groups in energetic plasticizers?
- For azido groups, the introduction of azido groups in energetic plasticizers is to use -N 3 in nucleophilic reagent NaN 3 to replace halogen (-X) , trifluoromethane sulfonate (-OTf) , nitrate ester (-ONO 2) and other leaving groups.
- What are energetic plasticizers?
- In modern energetic propellant composition, conventional plasticizers are being gradually replaced by energetic plasticizers having nitro, nitroamino, azido and other energetic groups or combination of energetic groups in the same molecule.
- Can nitramine be used in azido plasticizers?
- In recent years, novel azido plasticizers containing various energetic groups have been developed. Among these, the introduction of a nitramine group into the azido plasticizer has shown significant improvements in oxygen balance, density, and sensitivity compatibility.
- Why do we use plasticizers in gun propellants?
- Plasticizers can enhance the low temperature mechanical properties, reduce migration and volatilization both in gun propellants and solid propellants. However, gun propellants typically strive for a low combustion temperature and pure gas to prevent gun barrel erosion, whereas solid propellants require higher energy to elevate the specific impulse.
- What is azidation modification of energetic compounds?
- Azidation modification of energetic compounds allows for the preparation of a series of azido energetic plasticizers with different functional groups, such as azido nitro, azido esters, and azidonitramines [, , ]. Representative energetic plasticizers with various functional groups are depicted in Fig. 1.
