【摘要】：采用熱重(TG)和差示掃描量熱法(DSC)研究了三氧化二鐵(Fe_2O_3)、氧化銅(CuO)、亞鉻酸銅(Cr_2Cu_2O_5)、碳酸鉛(PbCO_3)、3-硝基-1,2,4-三唑-5-酮(NTO)鉛鹽(NP)、檸檬酸鉛(C_6H_5O_7Pb)、炭黑(CB)對聚疊氮縮水甘油醚(GAP)基含能熱塑性聚氨酯彈性體(ETPE)熱分解性能的影響。結(jié)果表明:幾種燃速催化劑主要對GAP基ETPE中疊氮基團(tuán)熱分解產(chǎn)生較大影響。其中,CuO和Cr_2Cu_2O_5使GAP基ETPE中疊氮基團(tuán)分解峰溫分別提前了21.9,13.6℃,Fe_2O_3、PbCO_3、C_6H_5O_7Pb、NP和CB使GAP基ETPE中疊氮基團(tuán)分解峰溫分別滯后了1.7,2.6,1.6,1.0,1.1℃;CuO、Cr_2Cu_2O_5、C_6H_5O_7Pb、CB使GAP基ETPE中疊氮基團(tuán)表觀分解熱分別增加75.5,84,43.4,103.1J·g~(-1),Fe_2O_3、PbCO_3和NP使GAP基ETPE中疊氮基團(tuán)表觀分解熱分別降低137.9,58.8,47.3J·g~(-1)。綜合比較認(rèn)為,CuO和Cr_2Cu_2O_5使GAP基ETPE中疊氮基團(tuán)分解峰溫提前,表觀分解熱增加,是催化GAP基ETPE熱分解理想的燃速催化劑。

Effect of Polyurethane Elastomer on Thermal decomposition property. The results show that several kinds of burning rate catalysts mainly affect the thermal decomposition of azide groups in GAP based ETPE. 鍏朵腑,CuO鍜孋r_2Cu_2O_5浣縂AP鍩篍TPE涓彔姘熀鍥㈠垎瑙ｅ嘲娓╁垎鍒彁鍓嶄簡21.9,13.6鈩，
