摘要/Abstract

摘要：

以十六烷基三甲基溴化铵为表面改性剂制备了有机膨润土, 并制备了以甲基丙烯酸十六酯为单体的吸油树脂/有机膨润土复合材料. 采用X射线衍射仪(XRD)、傅里叶变换红外光谱仪(FTIR)、扫描电子显微镜(SEM)对样品进行分析. 结果表明, 经十六烷基三甲基溴化铵改性的膨润土层间距由原来的1.12 nm增大到1.87 nm; 所得有机膨润土/吸油树脂复合材料对四氯化碳的饱和吸油率为16.3 g/g.

关键词: 高吸油树脂, 有机膨润土, 饱和吸油率

Abstract:

Cetyl-trimethyl ammonium bromide(CTAB) was used as a surface modifier to prepare hydrophobic organic bentonite. Then hexadecyl methacrylate was used to synthesize oil-absorptive resin with organic bentonite. X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FTIR) and scanning electron microscopy(SEM) were used to characterize the samples. The results show that the layer spacing of bentonite increases from 1.12 nm to 1.87 nm. When the concentrations(mass ratio to the monomer, hexadecyl methacrylate) of divinylbenzene(DVB), benzoyl peroxide(BPO), polyvinyl alcohol(PVA) and organic bentonite were 1.4%, 1.2%, 0.8% and 0.2%, respectively, the oil absorbency of the resin could reach 16.3 g/g.

Key words: High-oil adsorption resin, Organic bentonite, Oil absorption
