摘　　要：为研究聚丙二醇二缩水甘油醚(JH-230)对热固性形状记忆环氧树脂基本性能的影响,将异佛尔酮二胺(IPDA)与具有不同分子量比的氢化双酚A型环氧树脂(AL-3040)、聚丙二醇二缩水甘油醚(JH-230)共混,经完全固化制备出一种新型的形状记忆氢化双酚A型环氧树脂。借助傅里叶红外光谱仪(FT-IR)、差示扫描量热仪(DSC)、动态热机械分析仪(DMA)和拉伸-回复形状记忆测试分析了热固性形状记忆环氧树脂的分子结构以及JH-230对固化体系玻璃化转变温度、储能模量和形状记忆性能的影响。研究表明,JH-230可以增加固化体系链段的柔韧性;固化体系的玻璃化转变温度与动态模量随JH-230含量的增加而降低;该形状记忆氢化双酚A型环氧树脂体系具有良好的形状记忆性能,且形变完全回复时间随JH-230含量的增加而延长。In order to study the effect of polypropylene glycol diglycidyl ether(JH-230)on the basic properties of thermosetting shape memory epoxy resin,a novel shape memory hydrogenated bisphenol A epoxy resin was prepared by the hydrogenated bisphenol A epoxy resin(AL-3040),polypropylene glycol diglycidyl ether(JH-230)and isophorone diamine(IPDA)with different molar ratios between the AL-3040 and the JH-230.The molecular structures of the thermosetting shape memory epoxy resin were mea-sured by the flourier transform infrared spectroscopy(FT-IR),the glass-transition temperature(T g)of the epoxy resin was studied by the differential scanning calorimetry(DSC),and the corresponding storage modulus and shape memory property were observed by the dynamic thermomechanical analyzer(DMA)and tensile-recovery shape memory test.Results showed that the flexibility of the epoxy resin increased and the T g of the epoxy resin decreased with increased JH-230 content.The storage modulus of the epoxy resin decreased and the complete recovery time of the epoxy resin extended with increased JH-230 content.It was suggested that the flexibility,T g and storage modulus of epoxy resin can be controlled by adjusting the JH-230 content,and the shape memory hydrogenated bisphenol A epoxy resin has good shape memory property.
