| 摘 要： | 为了考察蒙脱土/木材复合材料的结晶性能，利用X射线衍射仪检测了以处理木材试样和蒙脱土为原材料、借助酚醛树脂制备的蒙脱土/木材复合材料，并将未处理试材、处理试材及复合材料进行比较后发现，试材经氢氧化钠、微波、氢氧化钠-微波、氢氧化钠-超声波处理后，相对结晶度降低；超声波处理后，相对结晶度增大。除氢氧化钠处理试材外，其他处理试材与蒙脱土形成的复合材料的结晶度均进一步降低。未处理材、处理材及复合材料结晶区晶层间距变化不明显。研究还发现，蒙脱土在复合材料中主要以插层型结构存在。

| Abstract: | For investigating crystal properties,the montmorillonite-wood composite(MPW),which is compound of wood and MMT with medium of phenol formaldehyde resin(PF),was scanned by X-ray diffraction,and compared with treated and untreated wood samples. Results were found that relative crystallinities of the samples,treated by liquid of sodium hydroxide (NaOH),microwave (MW),NaOH/MW and NoOH/ ultrasonic(US),were decreased compared with those of untreated wood samples,but relative crystallinities of US treated wood samples were increased. Comparing the treated samples,relative crystallinities of MPW,which was compounded with MMT and treated wood samples excepting for NaOH treatment wood samples,were decreased more. The layer space among untreated samples,treated samples and MPW changed unobviously confirmed by X-ray diffraction. It was also found that MMT mainly existed in MPW at intercalation state. |
