| 摘 要： | 以丁羟液体橡胶(HTPB)、N,N-双(2-羟丙基)苯胺(BHA)和甲苯二异氰酸酯(TDI)制得丁羟聚氨酯预聚体,然后用3,3'-二氯-4,4'-二氨基二苯甲烷(MOCA)固化制备了丁羟聚氨酯弹性体；研究了合成方法、不同二元醇、反应温度、反应时间、预聚体中-NCO质量分数及固化工艺对丁羟聚氯酯弹性体力学性能的影响.利用红外光谱分析了不同固化温度的丁羟聚氨酯弹性体,结果显示弹性体的微相分离程度从高温到低温梯度降低.

| Abstract: | A series of polyurethane elastomers were prepared by pre-polymerization method using hydroxyl-terminated polybutadiene（ HTPB）, N, N bis （2-hydroxylpropylene） anitin （BHA） and toluene diisocyanate（TDI） as materials, and using 4, 4＇-methylene bis （2-chloroaniline） （MOCA） as chain ex tender. The influences on the mechanical properties of polyurethane elastomers were studied, including the synthetic method, polyol, reaction temperature, reaction time, the content of --NCO in polyure- thane prepolymer and curing technology. Through FTIR spectroscopy of different curing temperature polyurethane elastomer research shows elastomer micro phase separation degree gradually increasing. |
