| 摘 要： | 为探索性能优异的高聚物增强木质基复合材料的制备方法,以大青杨木材为研究对象,选用双功能性单体甲基丙烯酸缩水甘油酯(GMA)和丙烯酸类单体甲基丙烯酸甲酯(MMA),通过加热引发聚合的方式制得P(GMA-co-MMA)/木材复合材料。利用SEM、FTIR和XRD表征其结构,并测试其相关性能。结果表明:GMA的加入,使高聚物与木材细胞壁紧密接触,界面相互作用力增强;GMA一端的环氧基团,与木材细胞壁上的羟基充分发生了化学反应,其双键与MMA单体发生自由基共聚合反应,从而使P(GMA-co-MMA)接枝在木材细胞壁上,并且主要以无定形态存在。与未改性的木材相比,P(GMA-co-MMA)/木材复合材料的静曲强度(MOR)、尺寸稳定性、防腐性能和热稳定性依次提高90.53%、54.05%、92.85%和31℃。

| Abstract: | In order to prepare a polymer reinforced wood-based composite with excellent properties,a fast-growing wood,Populus ussuriensis Kom,and glycidyl methacrylate(GMA) as a difunctional monomer and methyl methacrylate(MMA) as an acrylate monomer were selected,and the monomers were impregnated into the porous structure of wood and further initiated by a catalyst-thermal treatment for their in situ polymerization.The composite's structure was characterized by SEM,FTIR and XRD,and its corresponding properties were ... |
