【摘要】：采用热重(TG)和差示扫描量热法(DSC)研究了三氧化二铁(Fe_2O_3)、氧化铜(CuO)、亚铬酸铜(Cr_2Cu_2O_5)、碳酸铅(PbCO_3)、3-硝基-1,2,4-三唑-5-酮(NTO)铅盐(NP)、柠檬酸铅(C_6H_5O_7Pb)、炭黑(CB)对聚叠氮缩水甘油醚(GAP)基含能热塑性聚氨酯弹性体(ETPE)热分解性能的影响。结果表明:几种燃速催化剂主要对GAP基ETPE中叠氮基团热分解产生较大影响。其中,CuO和Cr_2Cu_2O_5使GAP基ETPE中叠氮基团分解峰温分别提前了21.9,13.6℃,Fe_2O_3、PbCO_3、C_6H_5O_7Pb、NP和CB使GAP基ETPE中叠氮基团分解峰温分别滞后了1.7,2.6,1.6,1.0,1.1℃;CuO、Cr_2Cu_2O_5、C_6H_5O_7Pb、CB使GAP基ETPE中叠氮基团表观分解热分别增加75.5,84,43.4,103.1J·g~(-1),Fe_2O_3、PbCO_3和NP使GAP基ETPE中叠氮基团表观分解热分别降低137.9,58.8,47.3J·g~(-1)。综合比较认为,CuO和Cr_2Cu_2O_5使GAP基ETPE中叠氮基团分解峰温提前,表观分解热增加,是催化GAP基ETPE热分解理想的燃速催化剂。
