采用悬浮接枝聚合法合成了木质纤维素–g–甲基丙烯酸丁酯插层有机蒙脱石(LNC–g–BMA/OMMT)吸油性树脂,对汽油的吸油率可达9 873.1 mg/g。采用Fourier红外光谱、X射线衍射、扫描电子显微镜和孔隙比表面积分析仪等对吸油性树脂的形貌和结构进行表征,分析了有机蒙脱石、引发剂、交联剂、分散剂用量以及水油比对树脂吸油性能的影响。结果表明,LNC―g―BMA/OMMT吸油性树脂表面疏松,有利于汽油分子在树脂内扩散;蒙脱石经有机化改性后层间距扩大,聚合物插入到有机蒙脱石片层中,通过破坏有机蒙脱石的片层结构使有机蒙脱石基本单元均匀分散于聚合物基体中。
The LNC-g-BMA / OMMT oil-absorbing resin was synthesized by suspension graft polymerization and its oil absorption rate to gasoline was up to 9 873.1 mg / g . The morphology and structure of the oil-absorbent resin were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy and pore specific surface area analyzer. The effects of organic montmorillonite, initiator, crosslinking agent, dispersant and water Effect of Oil Ratio on Resin Oil Absorption. The results showed that the surface of LNC-g-BMA / OMMT oil-absorbing resin was loose, which was conducive to the diffusion of gasoline molecules in the resin. The interlayer spacing of the modified montmorillonite was enlarged after the organic modification, and the polymer was inserted into the organic montmorillonite. By destroying the lamellar structure of the montmorillonite, the montmorillonite basic units are uniformly dispersed in the polymer matrix.
