有机膨润土的制备及其结构表征
Study on the Preparation and Structure Characterization of Organobentonites
摘要:
本文利用十六烷基三甲基溴化铵(CTAB)对辽宁黑山的Na-膨润土进行有机改性,并利用XRD、FTIR和TG等手段对有机膨润土的结构进行表征。结果表明:CTAB有效地插层进入了膨润土的层状结构中,增大了片层间距且具有良好的疏水性,从而拓宽了膨润土的应用领域。
Abstract:
This paper is based on the use of artificial Na-bentonite as raw material, cetrimonium bromide (CTAB) as modifier of Na-base bentonite for organic modification. The structure and properties of the Na-bentonites and organobentonites are characterized by means of XRD, FTIR and TG. The results showed that CTAB effectively entered layered structure of bentonite, increasing the layer spacing and providing with a good hydrophobicity, which widened application fields of Na-bentonite.
