Study on Preparation and Characterization of Modified Montmorillonite with the Aromatic Isocyanate

Abstract:

In this article, the methylene diphenyl isocyanate (MDI) containing two benzene rings was used to modify montmorillonite. The detection analysis of the original MMT and the samples after modification were investigated by infrared spectroscopy (FT-IR), x-ray diffraction (XRD) and thermo gravimetry (TG). Analysis of detection results shows that MDI and the surface of montmorillonite form chemical bonds and the spacing of montmorillonite layer increases from 1.24 nm to 1.86 nm. It provides highly active terminal isocyanate groups in situ polymerization for the montmorillonite and smart materials. It will improve the compatibility of the MMT and polymer, and allows the montmorillonite have always been able to maintain a good dispersion in polymer. Meanwhile the diphenyl isocyanate into ring can improve the heat stability of montmorillonite-modified polymer.
