摘要

The organically modified smectite-type clay in the epoxy resin is dispersed together with the diglycidyl ether (DGEBA) of bisphenol-A, and anhydrous nadic methyl (NMA) and / or benzydimethylamine (BDMA) and / The epoxy-silicate nanocomposites are cured at 100-200C in the presence of trifluoro-monoethylamine (BTMA) to produce epoxy-silicate nanocomposites. Crosslinking with a smectite layer with good wettability of the silicate surface by the epoxy substrate and spacing of To obtain a molecular dispersion of the layers in the bonded ecchymetics. The curing reaction is a direct attachment of the polymer network to the molecularly dispersed silicate layer by the cross-linking reaction of the functional groups of the alkylammonium ions located in the corrugations of the organically modified clay. Nanocomposites exhibit broad Tg at slightly higher temperatures than unmodified epoxy. The dynamic storage of nanocomposites appears to have a much higher glacier area and a much higher rubbery flatness area than these modules of unmodified epoxy.
