| 摘 要： | 以四氢甲基苯酐(MeTHPA)为固化剂,超支化聚酰胺酯(HBP)为增韧剂,制备了HBP/MeTHPA/环氧树脂(EP)固化体系。采用红外光谱(FT-IR)对HBP/MeTHPA/EP复合体系的固化机理进行了研究,并讨论了不同含量的HBP对固化体系热力学性能的影响。实验结果表明,HBP的加入会促进体系的固化反应;当w(HBP)=10%时力学性能最佳,冲击强度和拉伸强度分别增加了142.71%和34.44%,而玻璃化转变温度(Tg)有所下降,储能模量在玻璃态时均明显提高。

| Abstract: | With methyl tetrahydrophthalic anhydride(MeTHPA) as curing agent and hyperbranched polyamide ester(HBP) as toughener,the HBP/MeTHPA/epoxy resin(EP) curing system was prepared. The curing mechanism based on HBP/MeTHPA/EP composite system was researched by FT-IR spectra and the effects of HBP content on thermodynamics performance of the curing system were discussed. The experiment results indicated that the curing reaction could be accelerated by adding HBP. The mechanics performances were excellent when mass... |
