摘要
采用3,3-双叠氮甲基氧丁环(BAMO)/叠氮缩水甘油醚(GAP)无规共聚物为预聚物,多异氰酸酯(N100)、异佛尔酮二异氰酸酯(IPDI)为固化剂,1,4-丁二醇(BDO)为扩链剂合成了BAMO/GAP无规共聚物/N100/IPDI体系的粘合剂胶片,并对其进行了FT-IR、DSC、TG-DTG表征和力学性能测试。实验表明,所得的粘合剂胶片拉伸强度可达0.87 MPa,断裂延伸率大于106%,玻璃化转变温度在-50℃左右,热分解起始温度为217.0℃,具有较好的热稳定性。
The binder film of 3,3-bis （azidomethy） oxetane-r-（ glycidyl azide ） （ BAMO-r-GAP ） copolymer/N100/IPDI system was synthesized using BAMO-r-GAP copolymer as pre-polymer,N100 and IPDI as curing agent and BDO as chain extended agent. The Fourier transform infrared （ FT-IR ） spectrometer, differential scanning calorimetry （DSC） and thermogravimetry-derivative thermo- gravimetry（TG-DTG） were used to characterize the binder film, and the mechanical properties was also measured. Results show that the tensile strength of the binder film is raised to 0.87 MPa,and the breaking elongation is above 106%. The glass transition temperature （Tg） of the binder film is about -50 ℃ and the thermal decomposition starts at 217.0 ℃, which means the binder film has Rood thermal stability.
