乳液法有机蒙脱土/SBR纳米复合技术的改进

Modification of emulsion nano-compounding technology for organo-montmorillonite/SBR

对现有大分子乳液插层法制备蒙脱土 /SBR纳米复合材料技术进行改进。试验结果表明 ,使用低分子醇类混合物预分散有机蒙脱土 ,可使疏水的有机蒙脱土直接用于乳液插层法制备有机蒙脱土 /SBR纳米复合材料 ;在SBR胶乳中加入少量带羟基的聚合物水溶液 ,能够使有机蒙脱土层间距扩大 ,有利于提高插层动力 ;

The technology of montmorillonite/SBR composite prepared by macromolecular emulsion intercalation was modified.The test results showed that the hydrophobic organo-montmorillonite,which was predispersed in a low molecular alcoholic mixture,was directly used to prepare organo-montmorillonite/SBR nano-composite by emulsion intercalation;the distance between the layers of organo-montmorillonite was extended by adding small amount of water solution of a polymer with hydroxyl to SBR latex,which was beneficial to increase the intercalating power;and the ultrasonic had little effect on the enhancement of polymer intercalation.
