| Abstract: | By optimizing modifying reaction conditions(surfactant loadings,reaction time),a series of organically-modified montmorillonite(MMT) are prepared from natural MMT by cation exchange with cetyltrimethylammonium bromide(1631-Br).The organic MMT is characterized by XRD,FT-IR and TEM.The results indicate that MMT compatibility with the polymer and matrix asphalt is obviously improved when adding 25% of the surfactant loadings reacting 2 hours. |
