摘　　要：研究了胺类防老剂H（N，N-二苯基对苯二胺）和酚类防老剂甲叉4426－S（硫代双-（3，5一二特丁基-4-羟苄基）对HTPB-IPDI高燃速推进剂流变和力学性能的影响。实验结果表明，合防老剂H的推进剂药浆表现粘度增大，剪切速率指数变小，药浆的流动流平性变差，而甲叉4426-S对推进剂药浆的流动流平性影响较小。当推进剂的常温抗拉强度σm，相当时。加入防老剂H的推进剂其他力学性能比空白和含甲叉4426-S配方的力学性能略有提高。The effects of antioxidant H (N, N-diphenyl-p-phenylene diamine and 4426-S (sulfurized di- (3, 5-di-tert-butyl-4-hydroxylbenzyl) ) on rheologic and mechanical properties of HTPB/IPDI propellant with highburning rate is studied. The results show that the apparent viscosity of proPellant slurry with antioxidant Hincreases, shear rate exponent reduces, but the flowability and leveling of propellant slurry becomes poor.Antioxidant 4426-S has minor effect on the folwability and leveling of propellant slurry. Keeping same tensilestrength at room temperature, other mechanical property of propellant with antioxidant H are better thanthat of the blank propellant and the propellant with antioxidant 4426-S.
