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

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.
