Abstract

Bentonites are composed predominantly of the clay minerals montmorillonites, a sub-group within the smectites group.Raw bentonite collected from Potiskum Yobe State Nigeria were dried, grounded to mesh and sieved. The raw bentonite were purified using sodium hexa meta phosphate (NaPO3)6 dispersing agent to enhance its dispersion property followed by modification using tetra phenyl phosphonium bromide (TPPB) surfactant to turn it to organo-bentonite there by creating an active center for intercalation and enhance its fire retardant property. The DGEBA epoxy resin/modified bentonite composite were prepared using the modified bentonite incorporated into Diglycidyl ether of bisphenol A (DGEBA) epoxy matrix. The raw bentonite, modified bentonite and the prepared composite samples were characterized by Fourier transform infrared spectroscopy (FT-IR) and Scanning electron microscopy (SEM). The FT-IR Spectral data indicated that, the raw bentonite were successfully purified, modified and showed evidence of chemical interaction with the DGEBA epoxy resin matrix while, the SEM analysis indicated that both the raw and modified bentonite were dispersed completely in the matrix. The resultsfurther showed that, organically modified bentonite exhibited better dispersion than the raw bentonite.
