改性蒙脱土/双马来酰亚胺复合材料微观形貌及力学性能
|
Abstract:
采用聚醚胺（POP）和十八烷基三甲基氯化铵（OTAC）作为改性剂，通过离子交换法制备了改性蒙脱土（POP-MMT和OTAC-MMT）；以4，4'-二氨基二苯甲烷双马来酰亚胺（MBMI）、3，3'-二烯丙基双酚A（BBA）、双酚A和双烯丙基醚（BBE）为原料制备了复合材料基体（MBMI-BBA-BBE）；利用原位聚合法将POP-MMT和OTAC-MMT分别掺杂于基体中制备POP-MMT/MBMI-BBA-BBE和OTAC-MMT/MBMI-BBA-BBE复合材料。FTIR图谱显示，两种改性蒙脱土片层中均引入了新的基团并成功实现改性。XRD结果表明，OTAC-MMT和POP-MMT层间距相对于钠基蒙脱土（Na-MMT）均增大。SEM图像显示：复合材料的表面更加粗糙，改性蒙脱土分散均匀，出现了银纹和微裂纹并向不同方向发展，呈韧性断裂。力学性能测试结果表明：POP-MMT/MBMI-BBA-BBE和OTAC-MMT/MBMI-BBA-BBE的冲击强度及弯曲强度均先增加后降低，且均高于Na-MMT/MBMI-BBA-BBE和MBMI-BBA-BBE，力学性能提高明显，尤其OTAC-MMT/MBMI-BBA-BBE复合材料的效果更为显著。 Taking poly(oxypropylene)-polyamines (POP) and cetyltrimethyl ammonium chloride(OTAC) as modifier, modified montmorillonite(POP-MMT and OTAC-MMT) was prepared via cation exchange. 4,4'-diamino diphenyl methane bismaleimide (MBMI), 3,3'-diallyl bisphenol A (BBA) and bisphenol-A diallyl ether (BBE) were used to synthesize MBMI-BBA-BBE matrix. POP-MMT/MBMI-BBA-BBE and OTAC-MMT/MBMI-BBA-BBE composites were prepared from MBMI-BBA-BBE, POP-MMT and OTAC-MMT by in-situ polymerization method, respectively.The results of FTIR spectra show that new groups have been introduced into the layers of two kinds of modified montmorillonite and organized successfully. The XRD result reveals that the interlayer spacing of POP-MMT and OTAC-MMT increases compared with sodium montmorillonite(Na-MMT). The SEM images display that the surface of composites is more rough, modified MMT disperses uniformly, crazing and microcrack appear and direct in different directions, and the composites exhibit ductile fracture. The test results of mechanical properties of composites show that the tendency of the bending strength and the impact strength of composites first increase and then decrease, which are higher than that of Na-MMT/MBMI-BBA-BBE and MBMI-BBA-BBE, the mechanical properties increase significantly, especially the effect of OTAC-MMT/MBMI-BBA-BBE is more obvious. 哈尔滨创新人才专项（2015RAXXJ029）
