| 摘 要： | 以3,3-双叠氮甲基环氧丁烷-3-叠氮甲基-3-甲基环氧丁烷(BAMO-AMMO)无规共聚物为预聚物,甲苯二异氰酸酯(TDI)和1,4-丁二醇(BDO)为固化剂,三羟甲基乙烷(TME)为交联剂,制备了BAMO-AMMO/TDI/BDO/TME含能粘合剂胶片,并进行了力学性能、溶度参数、DSC和DMA的表征。在TME的质量分数为(TME+BDO)的30%时,胶片的拉伸强度可达6.34 MPa,延伸率为475%。BAMO-AMMO胶片与硝酸酯类增塑剂的溶度参数相近,具有良好的相溶性。随着TME含量的增大,胶片的玻璃化转变温度依次为-33.52℃(w(TME)=10%),-32.37℃(w(TME)=20%),-31.25℃(w(TME)=30%),-31.81℃(w(TME)=40%),-30.64℃(w(TME)=50%),呈现出升高的趋势。在-70℃胶片出现β次级转变。

| Abstract: | 3,3-bisazidomethyloxetane-3-azidomethyl-3-methyloxetane(BAMO-AMMO)/toluene diisocyanate(TDI)/1,4-butanediol(BDO)/pentaglycerine(TME) energetic binder films were prepared using BAMO-AMMO random copolymer as prepolymer,TDI and BDO as curing agents and TME as crosslinking agent.Mechanical analysis,solubility measurement,DSC and DMA were used to charactize the film.The tensile strength of the binder film raises to 6.34 MPa and the breaking elongation is 475% when the mass fraction TME is 30% in TEM+BDO.Solubility parameters of BAMO-AMMO binder film is close to that of the nitrate ester plasticizers commonly used in propellant,showing the excellent miscibility.Glass transition temperatures of the binder film gradually increase with the increase of TME content.β transition appears at-70 ℃. |
