摘要/Abstract

摘要： 研究了防老剂H（N，N’-二苯基对苯二胺）对丁羟推进剂力学性能的影响，从力学性能的角度提出了防老剂H在HTPB／TDI型推进剂中的最佳用量。发现防老剂H影响丁羟推进剂性能的规律与固化剂种类有关，如果不加入防老剂H，则HTPB／IPDI推进剂的力学性能会显著优于HTPB／TDI推进剂。

Abstract: The effect of antioxidant H (N, N’-diphenyl-p-phenylene diamine) on mechanicalproperties of HTPB propellant is studied. The optimum content of antioxidant H used in HTPB/TDIpropellants is obtained in terms of mechanical properties, and it is also noted that the effect ofantioxidant H is dependent on the kind of curing agent. If antioxidant H is not used in thepropellants, the mechanical properties of HTPB/IPDI propellants are much better than those ofHTPB/TDI propellants.
