Direct Analysis of Heavily Loaded Carbon Black Filled Styrene-Butadiene Rubber Used in Tank Track Pads by FT-IR

摘要

Infrared spectra have been obtained of a heavily loaded (50 per hundred) carbon black filled styrene-butadiene rubber using a Fourier transform infrared spectrometer (FT-IT). Attenuated total reflectance (ATR) spectroscopy sampling employing a germanium (Ge) internal reflectance element was found to yield quality infrared spectra where other techniques have failed. Subtle changes were observed between the spectra of the filled and unfilled styrene-butadiene rubber (SBR). These changes are attributed to the interaction between polymer and filler.
