摘要:
以三羟甲基丙烷(TMP)为交联剂,在较低交联参数下制得力学性能改善的聚叠氮缩水甘油醚(GAP)聚氨酯弹性体。采用傅里叶变换红外光谱(FT-IR)和X-射线衍射仪(WXRD)表征制备的GAP弹性体结构,动态力学热分析(DMA)、万能材料试验机、邵氏硬度仪和热重(TG)分析研究其高、低温力学及热分解特性。结果表明,该GAP弹性体具有叠氮型聚醚聚氨酯弹性体的结构特征,热稳定性较好。GAP弹性体试样经交联后,其常温力学强度显著提高,高温蠕变程度显著降低,但同时储能模量和玻璃化转变温度Tg略升高。其中GAP-T0.06弹性体试样的综合力学性能较好,其抗拉强度可达27.1 MPa,断裂伸长率为750%,Tg为-16.0 ℃,邵尔-A硬度为72.1 HA。
Abstract:
The glycidyl azide polymer(GAP)polyurethane elastomer with better mechanical properties are prepared by taking the trimethylolpropane(TMP)as the cross-linking agent under the condition of low cross-linking degree.The structure of the GAP elastomer is characterized by the Fourier transform infrared spectroscopy(FT-IR)and the wide X-ray diffraction(WXRD).The thermal and mechanical properties in the wide temperature range are investigated by the dynamic mechanic analysis(DMA),the universal testing machine,the Shore durometer,and the thermogravimetric(TG)analysis.The results reveal that the prepared GAP elastomers have typical features of azido-typed polyether-based polyurethane and good thermal stability.The slightly cross-linked structure promotes the mechanical properties in the room temperature effectively and reduces the degree of creep in high temperature observably,but makes the storage modulus and the Tg rise slightly.Among the samples,GAP-T0.06 samples with the tensile strength 27.1 MPa,the elongation strength 750%,the Tg -16.0 ℃ and the HA Shore-A hardness 72.1 exhibit better mechanical properties.
