| Abstract: |
| The interfacial interaction of carbon black/NBR was investigated by using Fourier transform infrared spectroscopy（FTIR）.The results showed that，compared with unfilled NBR compound，the C≡N stretching vibrational absorption，C一H bending vibrational absorption of trans 1，4-butadiene groups and C一H bending vibrational absorption of methylene of carbon black/NBR compound showed red-shift，but those vibrational absorptions of titanium dioxide/NBR compound showed no shift.The type of carbon black had little influence on the FTIR spectrum of carbon black/NBR compound.The simulation experiments of small function molecules showed that carboxylic acid，carboxyl groups and big benzene ring system of carbon black had large contribution to the interfacial interaction of NBR and carbon black.The ammonolysis experiments showed that the interaction betweencarbon black and 一CH＝CH一 and 一CH2 was different from the hydrogen-bond interaction between carbon black and 一C≡N. |
