摘要
采用傅里叶转换红外光谱仪研究炭黑与丁腈橡胶(NBR)的界面作用。结果表明:与未添加填料的NBR混炼胶相比,炭黑/NBR混炼胶的C■N伸缩振动峰、反式1,4-丁二烯基团C—H键的弯曲振动峰和亚甲基C—H键的弯曲振动峰均发生红移,而二氧化钛/NBR混炼胶的上述振动峰无变化;炭黑品种对炭黑/NBR混炼胶各基团的红外特征峰影响不大。小分子模拟试验表明炭黑表面的羧基、羧酸基团及炭黑的大苯环体系对其与NBR的相互作用贡献较大;氨解试验表明炭黑与—CH—CH—和—CH2的作用不同于与—C■N的氢键作用。
The interracial 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--H bending vibrational absorption of trans 1, 4-butadiene groups and C--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 interracial in- teraction of NBR and carbon black. The ammonolysis experiments showed that the interaction between carbon black and --CH=CH-- and --CH2 was different from the hydrogen-bond interaction between carbon black and --C≡N .
