【摘要】 采用压延机，在加工温度不高于１２０°Ｃ的条件下，成功地制备出热塑型聚氨酯弹性体（ＴＰＵ）与高氯酸铵、铝粉及增塑剂邻苯二甲酸二丁酯（ＤＢＰ）等组成的复合胶片，拉伸实验结果指出了所制备的热塑性弹性体复合体系具有良好的力学性能，完全达到或超过推进剂体系的要求指标。更多还原

【Abstract】 Composite films based on prepared thermoplastic polyurethanes (TPU),ammonium perchlorate (AP),aluminium powder,dibutyl phthalate (DBP) were prepared successfully by using calender with the process themperature no more than 120°C.Tensile test results indicated that these TPU composites have satisfactory mechanical properties which reach or surpass the property index for propellant system.更多还原
