Kinetic Study and Thermal Decomposition Behavior of Magnesium-Sodium Nitrate Based on Hydroxyl-Terminated Polybutadiene
This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...
متن کاملInvestigating the Effect of Curing Agent and Casting Temperature on Pot Life of Binder System Based on HTPB
Effect of temperature and curing agent type parameters on rheological behavior of binder system based on Hydroxyl terminated Polybutadiene (HTPB) is important in the aspect of production for medium and large-size grains. In this research, the effect of casting temperature 40, 50 and 60 ºC) and chemical structure of curing agents (TDI, IPDI and HDI) on rheological behavior of a binder system bas...
متن کاملStudies on Sheet Explosive Formulation Based on Octahydro-1,3,5,7-Tetranitro- 1,3,5,7-Tetrazocine and Hydroxyl Terminated Polybutadiene
The effect of replacing hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) by octahydro-1,3,5,7-tetranitro-1,3,5,7tetrazocine (HMX) in HTPB-binder on the performance, sensitivity, thermal, and mechanical properties of the sheet explosive formulation has been studied. The maximum loading of HMX was achieved up to 78 per cent in HTPB-binder system. The velocity of detonation (VOD) of HMX-based sheet e...
متن کاملبررسی اثر زنجیرافزاینده 4،4 َ- بیس(فنیل آمین) متان بر خواص مکانیکی و حرارتی شبکه پلی‌اوره- یورتان بر پایه HTPB
Polyurea-urethanes are one of the polyurethane categories that causes better phase separation due to increasing the hard segment length and non-covalent interactions. In this research, hydroxyl-terminated polybutadiene based polyurea-urethanes have been synthesized via one-pot polymerization of triethanol amine triflouroborate comlex as cross-linker, isophoron diisocyanate as curing agent and v...
متن کاملEffect of Hyperbranched Polyesters on HTPB Polyurethane Curing Kinetic
Effects of hyperbranched polyesters on kinetics of the reaction between hydroxyl-terminated polybutadiene (HTPB) and isophorone diisocyanate (IPDI) were investigated. HTPB and IPDI were in-situ cured in the presence of two different hyperbranched polyesters, stearic acid ester-terminated hyperbranched polyester (SHPE) and acetate-terminated hyperbranched polyester (AHPE). The curing processes w...
